+# CONTRIBUTING
+
+The libuv project welcomes new contributors. This document will guide you
+through the process.
+
+
+### FORK
+
+Fork the project [on GitHub](https://github.com/libuv/libuv) and check out
+your copy.
+
+```
+$ git clone https://github.com/username/libuv.git
+$ cd libuv
+$ git remote add upstream https://github.com/libuv/libuv.git
+```
+
+Now decide if you want your feature or bug fix to go into the master branch
+or the stable branch.  As a rule of thumb, bug fixes go into the stable branch
+while new features go into the master branch.
+
+The stable branch is effectively frozen; patches that change the libuv
+API/ABI or affect the run-time behavior of applications get rejected.
+
+In case of doubt, open an issue in the [issue tracker][], post your question
+to the [libuv discussions forum], or message the [libuv mailing list].
+
+Especially do so if you plan to work on something big. Nothing is more
+frustrating than seeing your hard work go to waste because your vision does not
+align with that of the [project maintainers].
+
+
+### BRANCH
+
+Okay, so you have decided on the proper branch.  Create a feature branch
+and start hacking:
+
+```
+$ git checkout -b my-feature-branch -t origin/v1.x
+```
+
+(Where v1.x is the latest stable branch as of this writing.)
+
+### CODE
+
+Please adhere to libuv's code style. In general it follows the conventions from
+the [Google C/C++ style guide]. Some of the key points, as well as some
+additional guidelines, are enumerated below.
+
+* Code that is specific to unix-y platforms should be placed in `src/unix`, and
+  declarations go into `include/uv/unix.h`.
+
+* Source code that is Windows-specific goes into `src/win`, and related
+  publicly exported types, functions and macro declarations should generally
+  be declared in `include/uv/win.h`.
+
+* Names should be descriptive and concise.
+
+* All the symbols and types that libuv makes available publicly should be
+  prefixed with `uv_` (or `UV_` in case of macros).
+
+* Internal, non-static functions should be prefixed with `uv__`.
+
+* Use two spaces and no tabs.
+
+* Lines should be wrapped at 80 characters.
+
+* Ensure that lines have no trailing whitespace, and use unix-style (LF) line
+  endings.
+
+* Use C89-compliant syntax. In other words, variables can only be declared at
+  the top of a scope (function, if/for/while-block).
+
+* When writing comments, use properly constructed sentences, including
+  punctuation.
+
+* When documenting APIs and/or source code, don't make assumptions or make
+  implications about race, gender, religion, political orientation or anything
+  else that isn't relevant to the project.
+
+* Remember that source code usually gets written once and read often: ensure
+  the reader doesn't have to make guesses. Make sure that the purpose and inner
+  logic are either obvious to a reasonably skilled professional, or add a
+  comment that explains it.
+
+
+### COMMIT
+
+Make sure git knows your name and email address:
+
+```
+$ git config --global user.name "J. Random User"
+$ git config --global user.email "j.random.user@example.com"
+```
+
+Writing good commit logs is important.  A commit log should describe what
+changed and why.  Follow these guidelines when writing one:
+
+1. The first line should be 50 characters or less and contain a short
+   description of the change prefixed with the name of the changed
+   subsystem (e.g. "net: add localAddress and localPort to Socket").
+2. Keep the second line blank.
+3. Wrap all other lines at 72 columns.
+
+A good commit log looks like this:
+
+```
+subsystem: explaining the commit in one line
+
+Body of commit message is a few lines of text, explaining things
+in more detail, possibly giving some background about the issue
+being fixed, etc etc.
+
+The body of the commit message can be several paragraphs, and
+please do proper word-wrap and keep columns shorter than about
+72 characters or so. That way `git log` will show things
+nicely even when it is indented.
+```
+
+The header line should be meaningful; it is what other people see when they
+run `git shortlog` or `git log --oneline`.
+
+Check the output of `git log --oneline files_that_you_changed` to find out
+what subsystem (or subsystems) your changes touch.
+
+
+### REBASE
+
+Use `git rebase` (not `git merge`) to sync your work from time to time.
+
+```
+$ git fetch upstream
+$ git rebase upstream/v1.x  # or upstream/master
+```
+
+
+### TEST
+
+Bug fixes and features should come with tests.  Add your tests in the
+`test/` directory. Each new test needs to be registered in `test/test-list.h`.
+
+If you add a new test file, it needs to be registered in three places:
+- `CMakeLists.txt`: add the file's name to the `uv_test_sources` list.
+- `Makefile.am`: add the file's name to the `test_run_tests_SOURCES` list.
+
+Look at other tests to see how they should be structured (license boilerplate,
+the way entry points are declared, etc.).
+
+Check README.md file to find out how to run the test suite and make sure that
+there are no test regressions.
+
+### PUSH
+
+```
+$ git push origin my-feature-branch
+```
+
+Go to https://github.com/username/libuv and select your feature branch.  Click
+the 'Pull Request' button and fill out the form.
+
+Pull requests are usually reviewed within a few days.  If there are comments
+to address, apply your changes in a separate commit and push that to your
+feature branch.  Post a comment in the pull request afterwards; GitHub does
+not send out notifications when you add commits.

+Using Creative Commons Public Licenses
+
+Creative Commons public licenses provide a standard set of terms and
+conditions that creators and other rights holders may use to share
+original works of authorship and other material subject to copyright
+and certain other rights specified in the public license below. The
+following considerations are for informational purposes only, are not
+exhaustive, and do not form part of our licenses.
+
+     Considerations for licensors: Our public licenses are
+     intended for use by those authorized to give the public
+     permission to use material in ways otherwise restricted by
+     copyright and certain other rights. Our licenses are
+     irrevocable. Licensors should read and understand the terms
+     and conditions of the license they choose before applying it.
+     Licensors should also secure all rights necessary before
+     applying our licenses so that the public can reuse the
+     material as expected. Licensors should clearly mark any
+     material not subject to the license. This includes other CC-
+     licensed material, or material used under an exception or
+     limitation to copyright. More considerations for licensors:

+
+     Considerations for the public: By using one of our public
+     licenses, a licensor grants the public permission to use the
+     licensed material under specified terms and conditions. If
+     the licensor's permission is not necessary for any reason--for
+     example, because of any applicable exception or limitation to
+     copyright--then that use is not regulated by the license. Our
+     licenses grant only permissions under copyright and certain
+     other rights that a licensor has authority to grant. Use of
+     the licensed material may still be restricted for other
+     reasons, including because others have copyright or other
+     rights in the material. A licensor may make special requests,
+     such as asking that all changes be marked or described.
+     Although not required by our licenses, you are encouraged to
+     respect those requests where reasonable. More_considerations

+
+By exercising the Licensed Rights (defined below), You accept and agree
+to be bound by the terms and conditions of this Creative Commons
+Attribution 4.0 International Public License ("Public License"). To the
+extent this Public License may be interpreted as a contract, You are
+granted the Licensed Rights in consideration of Your acceptance of
+these terms and conditions, and the Licensor grants You such rights in
+consideration of benefits the Licensor receives from making the
+Licensed Material available under these terms and conditions.
+
+
+Section 1 -- Definitions.
+
+  a. Adapted Material means material subject to Copyright and Similar
+     Rights that is derived from or based upon the Licensed Material
+     and in which the Licensed Material is translated, altered,
+     arranged, transformed, or otherwise modified in a manner requiring
+     permission under the Copyright and Similar Rights held by the
+     Licensor. For purposes of this Public License, where the Licensed
+     Material is a musical work, performance, or sound recording,
+     Adapted Material is always produced where the Licensed Material is
+     synched in timed relation with a moving image.
+
+  b. Adapter's License means the license You apply to Your Copyright
+     and Similar Rights in Your contributions to Adapted Material in
+     accordance with the terms and conditions of this Public License.
+
+  c. Copyright and Similar Rights means copyright and/or similar rights
+     closely related to copyright including, without limitation,
+     performance, broadcast, sound recording, and Sui Generis Database
+     Rights, without regard to how the rights are labeled or
+     categorized. For purposes of this Public License, the rights
+     specified in Section 2(b)(1)-(2) are not Copyright and Similar
+     Rights.
+
+  d. Effective Technological Measures means those measures that, in the
+     absence of proper authority, may not be circumvented under laws
+     fulfilling obligations under Article 11 of the WIPO Copyright
+     Treaty adopted on December 20, 1996, and/or similar international
+     agreements.
+
+  e. Exceptions and Limitations means fair use, fair dealing, and/or
+     any other exception or limitation to Copyright and Similar Rights
+     that applies to Your use of the Licensed Material.
+
+  f. Licensed Material means the artistic or literary work, database,
+     or other material to which the Licensor applied this Public
+     License.
+
+  g. Licensed Rights means the rights granted to You subject to the
+     terms and conditions of this Public License, which are limited to
+     all Copyright and Similar Rights that apply to Your use of the
+     Licensed Material and that the Licensor has authority to license.
+
+  h. Licensor means the individual(s) or entity(ies) granting rights
+     under this Public License.
+
+  i. Share means to provide material to the public by any means or
+     process that requires permission under the Licensed Rights, such
+     as reproduction, public display, public performance, distribution,
+     dissemination, communication, or importation, and to make material
+     available to the public including in ways that members of the
+     public may access the material from a place and at a time
+     individually chosen by them.
+
+  j. Sui Generis Database Rights means rights other than copyright
+     resulting from Directive 96/9/EC of the European Parliament and of
+     the Council of 11 March 1996 on the legal protection of databases,
+     as amended and/or succeeded, as well as other essentially
+     equivalent rights anywhere in the world.
+
+  k. You means the individual or entity exercising the Licensed Rights
+     under this Public License. Your has a corresponding meaning.
+
+
+Section 2 -- Scope.
+
+  a. License grant.
+
+       1. Subject to the terms and conditions of this Public License,
+          the Licensor hereby grants You a worldwide, royalty-free,
+          non-sublicensable, non-exclusive, irrevocable license to
+          exercise the Licensed Rights in the Licensed Material to:
+
+            a. reproduce and Share the Licensed Material, in whole or
+               in part; and
+
+            b. produce, reproduce, and Share Adapted Material.
+
+       2. Exceptions and Limitations. For the avoidance of doubt, where
+          Exceptions and Limitations apply to Your use, this Public
+          License does not apply, and You do not need to comply with
+          its terms and conditions.
+
+       3. Term. The term of this Public License is specified in Section
+          6(a).
+
+       4. Media and formats; technical modifications allowed. The
+          Licensor authorizes You to exercise the Licensed Rights in
+          all media and formats whether now known or hereafter created,
+          and to make technical modifications necessary to do so. The
+          Licensor waives and/or agrees not to assert any right or
+          authority to forbid You from making technical modifications
+          necessary to exercise the Licensed Rights, including
+          technical modifications necessary to circumvent Effective
+          Technological Measures. For purposes of this Public License,
+          simply making modifications authorized by this Section 2(a)
+          (4) never produces Adapted Material.
+
+       5. Downstream recipients.
+
+            a. Offer from the Licensor -- Licensed Material. Every
+               recipient of the Licensed Material automatically
+               receives an offer from the Licensor to exercise the
+               Licensed Rights under the terms and conditions of this
+               Public License.
+
+            b. No downstream restrictions. You may not offer or impose
+               any additional or different terms or conditions on, or
+               apply any Effective Technological Measures to, the
+               Licensed Material if doing so restricts exercise of the
+               Licensed Rights by any recipient of the Licensed
+               Material.
+
+       6. No endorsement. Nothing in this Public License constitutes or
+          may be construed as permission to assert or imply that You
+          are, or that Your use of the Licensed Material is, connected
+          with, or sponsored, endorsed, or granted official status by,
+          the Licensor or others designated to receive attribution as
+          provided in Section 3(a)(1)(A)(i).
+
+  b. Other rights.
+
+       1. Moral rights, such as the right of integrity, are not
+          licensed under this Public License, nor are publicity,
+          privacy, and/or other similar personality rights; however, to
+          the extent possible, the Licensor waives and/or agrees not to
+          assert any such rights held by the Licensor to the limited
+          extent necessary to allow You to exercise the Licensed
+          Rights, but not otherwise.
+
+       2. Patent and trademark rights are not licensed under this
+          Public License.
+
+       3. To the extent possible, the Licensor waives any right to
+          collect royalties from You for the exercise of the Licensed
+          Rights, whether directly or through a collecting society
+          under any voluntary or waivable statutory or compulsory
+          licensing scheme. In all other cases the Licensor expressly
+          reserves any right to collect such royalties.
+
+
+Section 3 -- License Conditions.
+
+Your exercise of the Licensed Rights is expressly made subject to the
+following conditions.
+
+  a. Attribution.
+
+       1. If You Share the Licensed Material (including in modified
+          form), You must:
+
+            a. retain the following if it is supplied by the Licensor
+               with the Licensed Material:
+
+                 i. identification of the creator(s) of the Licensed
+                    Material and any others designated to receive
+                    attribution, in any reasonable manner requested by
+                    the Licensor (including by pseudonym if
+                    designated);
+
+                ii. a copyright notice;
+
+               iii. a notice that refers to this Public License;
+
+                iv. a notice that refers to the disclaimer of
+                    warranties;
+
+                 v. a URI or hyperlink to the Licensed Material to the
+                    extent reasonably practicable;
+
+            b. indicate if You modified the Licensed Material and
+               retain an indication of any previous modifications; and
+
+            c. indicate the Licensed Material is licensed under this
+               Public License, and include the text of, or the URI or
+               hyperlink to, this Public License.
+
+       2. You may satisfy the conditions in Section 3(a)(1) in any
+          reasonable manner based on the medium, means, and context in
+          which You Share the Licensed Material. For example, it may be
+          reasonable to satisfy the conditions by providing a URI or
+          hyperlink to a resource that includes the required
+          information.
+
+       3. If requested by the Licensor, You must remove any of the
+          information required by Section 3(a)(1)(A) to the extent
+          reasonably practicable.
+
+       4. If You Share Adapted Material You produce, the Adapter's
+          License You apply must not prevent recipients of the Adapted
+          Material from complying with this Public License.
+
+
+Section 4 -- Sui Generis Database Rights.
+
+Where the Licensed Rights include Sui Generis Database Rights that
+apply to Your use of the Licensed Material:
+
+  a. for the avoidance of doubt, Section 2(a)(1) grants You the right
+     to extract, reuse, reproduce, and Share all or a substantial
+     portion of the contents of the database;
+
+  b. if You include all or a substantial portion of the database
+     contents in a database in which You have Sui Generis Database
+     Rights, then the database in which You have Sui Generis Database
+     Rights (but not its individual contents) is Adapted Material; and
+
+  c. You must comply with the conditions in Section 3(a) if You Share
+     all or a substantial portion of the contents of the database.
+
+For the avoidance of doubt, this Section 4 supplements and does not
+replace Your obligations under this Public License where the Licensed
+Rights include other Copyright and Similar Rights.
+
+
+Section 5 -- Disclaimer of Warranties and Limitation of Liability.
+
+  a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE
+     EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS
+     AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF
+     ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS,
+     IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION,
+     WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR
+     PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS,
+     ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT
+     KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT
+     ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.
+
+  b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE
+     TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION,
+     NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT,
+     INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES,
+     COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR
+     USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN
+     ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR
+     DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR
+     IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.
+
+  c. The disclaimer of warranties and limitation of liability provided
+     above shall be interpreted in a manner that, to the extent
+     possible, most closely approximates an absolute disclaimer and
+     waiver of all liability.
+
+
+Section 6 -- Term and Termination.
+
+  a. This Public License applies for the term of the Copyright and
+     Similar Rights licensed here. However, if You fail to comply with
+     this Public License, then Your rights under this Public License
+     terminate automatically.
+
+  b. Where Your right to use the Licensed Material has terminated under
+     Section 6(a), it reinstates:
+
+       1. automatically as of the date the violation is cured, provided
+          it is cured within 30 days of Your discovery of the
+          violation; or
+
+       2. upon express reinstatement by the Licensor.
+
+     For the avoidance of doubt, this Section 6(b) does not affect any
+     right the Licensor may have to seek remedies for Your violations
+     of this Public License.
+
+  c. For the avoidance of doubt, the Licensor may also offer the
+     Licensed Material under separate terms or conditions or stop
+     distributing the Licensed Material at any time; however, doing so
+     will not terminate this Public License.
+
+  d. Sections 1, 5, 6, 7, and 8 survive termination of this Public
+     License.
+
+
+Section 7 -- Other Terms and Conditions.
+
+  a. The Licensor shall not be bound by any additional or different
+     terms or conditions communicated by You unless expressly agreed.
+
+  b. Any arrangements, understandings, or agreements regarding the
+     Licensed Material not stated herein are separate from and
+     independent of the terms and conditions of this Public License.
+
+
+Section 8 -- Interpretation.
+
+  a. For the avoidance of doubt, this Public License does not, and
+     shall not be interpreted to, reduce, limit, restrict, or impose
+     conditions on any use of the Licensed Material that could lawfully
+     be made without permission under this Public License.
+
+  b. To the extent possible, if any provision of this Public License is
+     deemed unenforceable, it shall be automatically reformed to the
+     minimum extent necessary to make it enforceable. If the provision
+     cannot be reformed, it shall be severed from this Public License
+     without affecting the enforceability of the remaining terms and
+     conditions.
+
+  c. No term or condition of this Public License will be waived and no
+     failure to comply consented to unless expressly agreed to by the
+     Licensor.
+
+  d. Nothing in this Public License constitutes or may be interpreted
+     as a limitation upon, or waiver of, any privileges and immunities
+     that apply to the Licensor or You, including from the legal
+     processes of any jurisdiction or authority.

+## Storing a maintainer key in Git
+
+It's quite handy to store a maintainer's signature as a git blob, and have
+that object tagged and signed with such key.
+
+Export your public key:
+
+    $ gpg --armor --export saghul@gmail.com > saghul.asc
+
+Store it as a blob on the repo:
+
+    $ git hash-object -w saghul.asc
+
+The previous command returns a hash, copy it. For the sake of this explanation,
+we'll assume it's 'abcd1234'. Storing the blob in git is not enough, it could
+be garbage collected since nothing references it, so we'll create a tag for it:
+
+    $ git tag -s pubkey-saghul abcd1234
+
+Commit the changes and push:
+
+    $ git push origin pubkey-saghul

+
+## Overview
+
+libuv is a multi-platform support library with a focus on asynchronous I/O. It
+was primarily developed for use by [Node.js][], but it's also
+used by [Luvit](http://luvit.io/), [Julia](http://julialang.org/),
+[uvloop](https://github.com/MagicStack/uvloop), and [others](https://github.com/libuv/libuv/blob/v1.x/LINKS.md).
+
+## Feature highlights
+
+ * Full-featured event loop backed by epoll, kqueue, IOCP, event ports.
+
+ * Asynchronous TCP and UDP sockets
+
+ * Asynchronous DNS resolution
+
+ * Asynchronous file and file system operations
+
+ * File system events
+
+ * ANSI escape code controlled TTY
+
+ * IPC with socket sharing, using Unix domain sockets or named pipes (Windows)
+
+ * Child processes
+
+ * Thread pool
+
+ * Signal handling
+
+ * High resolution clock
+
+ * Threading and synchronization primitives
+
+## Versioning
+
+Starting with version 1.0.0 libuv follows the [semantic versioning](http://semver.org/)
+scheme. The API change and backwards compatibility rules are those indicated by
+SemVer. libuv will keep a stable ABI across major releases.
+
+The ABI/API changes can be tracked [here](http://abi-laboratory.pro/tracker/timeline/libuv/).
+
+## Licensing
+
+libuv is licensed under the MIT license. Check the [LICENSE file](LICENSE).
+The documentation is licensed under the CC BY 4.0 license. Check the [LICENSE-docs file](LICENSE-docs).

+
+## Documentation
+
+### Official documentation
+
+Located in the docs/ subdirectory. It uses the [Sphinx](http://sphinx-doc.org/)
+framework, which makes it possible to build the documentation in multiple
+formats.
+
+Show different supported building options:
+
+```bash
+$ make help
+```
+
+Build documentation as HTML:
+
+```bash
+$ make html
+```
+
+Build documentation as HTML and live reload it when it changes (this requires
+sphinx-autobuild to be installed and is only supported on Unix):
+
+```bash
+$ make livehtml
+```
+
+Build documentation as man pages:
+
+```bash
+$ make man
+```
+
+Build documentation as ePub:
+
+```bash
+$ make epub
+```
+
+NOTE: Windows users need to use make.bat instead of plain 'make'.
+
+Documentation can be browsed online [here](http://docs.libuv.org).
+
+The [tests and benchmarks](https://github.com/libuv/libuv/tree/master/test)
+also serve as API specification and usage examples.
+
+### Other resources
+
+ * [LXJS 2012 talk](http://www.youtube.com/watch?v=nGn60vDSxQ4)
+   &mdash; High-level introductory talk about libuv.
+ * [libuv-dox](https://github.com/thlorenz/libuv-dox)
+   &mdash; Documenting types and methods of libuv, mostly by reading uv.h.
+ * [learnuv](https://github.com/thlorenz/learnuv)
+   &mdash; Learn uv for fun and profit, a self guided workshop to libuv.
+
+These resources are not handled by libuv maintainers and might be out of
+date. Please verify it before opening new issues.
+
+## Downloading
+
+libuv can be downloaded either from the
+[GitHub repository](https://github.com/libuv/libuv)
+or from the [downloads site](http://dist.libuv.org/dist/).
+
+Before verifying the git tags or signature files, importing the relevant keys
+is necessary. Key IDs are listed in the
+[MAINTAINERS](https://github.com/libuv/libuv/blob/master/MAINTAINERS.md)
+file, but are also available as git blob objects for easier use.
+
+Importing a key the usual way:
+
+```bash
+$ gpg --keyserver pool.sks-keyservers.net --recv-keys AE9BC059
+```
+
+Importing a key from a git blob object:
+
+```bash
+$ git show pubkey-saghul | gpg --import
+```
+
+### Verifying releases
+
+Git tags are signed with the developer's key, they can be verified as follows:
+
+```bash
+$ git verify-tag v1.6.1
+```
+
+Starting with libuv 1.7.0, the tarballs stored in the
+[downloads site](http://dist.libuv.org/dist/) are signed and an accompanying
+signature file sit alongside each. Once both the release tarball and the
+signature file are downloaded, the file can be verified as follows:
+
+```bash
+$ gpg --verify libuv-1.7.0.tar.gz.sign
+```
+
+## Build Instructions
+
+For UNIX-like platforms, including macOS, there are two build methods:
+autotools or [CMake][].
+
+For Windows, [CMake][] is the only supported build method and has the
+following prerequisites:
+
+<details>
+
+* One of:
+  * [Visual C++ Build Tools][]
+  * [Visual Studio 2015 Update 3][], all editions
+    including the Community edition (remember to select
+    "Common Tools for Visual C++ 2015" feature during installation).
+  * [Visual Studio 2017][], any edition (including the Build Tools SKU).
+    **Required Components:** "MSbuild", "VC++ 2017 v141 toolset" and one of the
+    Windows SDKs (10 or 8.1).
+* Basic Unix tools required for some tests,
+  [Git for Windows][] includes Git Bash
+  and tools which can be included in the global `PATH`.
+
+</details>
+
+To build with autotools:
+
+```bash
+$ sh autogen.sh
+$ ./configure
+$ make
+$ make check
+$ make install
+```
+
+To build with [CMake][]:
+
+```bash
+$ mkdir -p build
+
+$ (cd build && cmake .. -DBUILD_TESTING=ON) # generate project with tests
+$ cmake --build build                       # add `-j <n>` with cmake >= 3.12
+
+# Run tests:
+$ (cd build && ctest -C Debug --output-on-failure)
+
+# Or manually run tests:
+$ build/uv_run_tests                        # shared library build
+$ build/uv_run_tests_a                      # static library build
+```
+
+To cross-compile with [CMake][] (unsupported but generally works):
+
+```bash
+$ cmake ../..                 \
+  -DCMAKE_SYSTEM_NAME=Windows \
+  -DCMAKE_SYSTEM_VERSION=6.1  \
+  -DCMAKE_C_COMPILER=i686-w64-mingw32-gcc
+```
+
+### Install with Homebrew
+
+```bash
+$ brew install --HEAD libuv
+```
+
+Note to OS X users:
+
+Make sure that you specify the architecture you wish to build for in the
+"ARCHS" flag. You can specify more than one by delimiting with a space
+(e.g. "x86_64 i386").
+
+### Running tests
+
+Some tests are timing sensitive. Relaxing test timeouts may be necessary
+on slow or overloaded machines:
+
+```bash
+$ env UV_TEST_TIMEOUT_MULTIPLIER=2 build/uv_run_tests # 10s instead of 5s
+```
+
+#### Run one test
+
+The list of all tests is in `test/test-list.h`.
+
+This invocation will cause the test driver to fork and execute `TEST_NAME` in
+a child process:
+
+```bash
+$ build/uv_run_tests_a TEST_NAME
+```
+
+This invocation will cause the test driver to execute the test in
+the same process:
+
+```bash
+$ build/uv_run_tests_a TEST_NAME TEST_NAME
+```
+
+#### Debugging tools
+
+When running the test from within the test driver process
+(`build/uv_run_tests_a TEST_NAME TEST_NAME`), tools like gdb and valgrind
+work normally.
+
+When running the test from a child of the test driver process
+(`build/uv_run_tests_a TEST_NAME`), use these tools in a fork-aware manner.
+
+##### Fork-aware gdb
+
+Use the [follow-fork-mode](https://sourceware.org/gdb/onlinedocs/gdb/Forks.html) setting:
+
+```
+$ gdb --args build/uv_run_tests_a TEST_NAME
+
+(gdb) set follow-fork-mode child
+...
+```
+
+##### Fork-aware valgrind
+
+Use the `--trace-children=yes` parameter:
+
+```bash
+$ valgrind --trace-children=yes -v --tool=memcheck --leak-check=full --track-origins=yes --leak-resolution=high --show-reachable=yes --log-file=memcheck-%p.log build/uv_run_tests_a TEST_NAME
+```
+
+### Running benchmarks
+
+See the section on running tests.
+The benchmark driver is `./uv_run_benchmarks_a` and the benchmarks are
+listed in `test/benchmark-list.h`.
+
+## Supported Platforms
+
+Check the [SUPPORTED_PLATFORMS file](SUPPORTED_PLATFORMS.md).
+
+### `-fno-strict-aliasing`
+
+It is recommended to turn on the `-fno-strict-aliasing` compiler flag in
+projects that use libuv. The use of ad hoc "inheritance" in the libuv API
+may not be safe in the presence of compiler optimizations that depend on
+strict aliasing.
+
+MSVC does not have an equivalent flag but it also does not appear to need it
+at the time of writing (December 2019.)
+
+### AIX Notes
+
+AIX compilation using IBM XL C/C++ requires version 12.1 or greater.
+
+AIX support for filesystem events requires the non-default IBM `bos.ahafs`
+package to be installed.  This package provides the AIX Event Infrastructure
+that is detected by `autoconf`.
+[IBM documentation](http://www.ibm.com/developerworks/aix/library/au-aix_event_infrastructure/)
+describes the package in more detail.
+
+### z/OS Notes
+
+z/OS compilation requires [ZOSLIB](https://github.com/ibmruntimes/zoslib) to be installed. When building with [CMake][], use the flag `-DZOSLIB_DIR` to specify the path to [ZOSLIB](https://github.com/ibmruntimes/zoslib):
+
+```bash
+$ (cd build && cmake .. -DBUILD_TESTING=ON -DZOSLIB_DIR=/path/to/zoslib)
+$ cmake --build build
+```
+
+z/OS creates System V semaphores and message queues. These persist on the system
+after the process terminates unless the event loop is closed.
+
+Use the `ipcrm` command to manually clear up System V resources.

+
+## Support types
+
+* **Tier 1**: Officially supported and tested with CI. Any contributed patch
+  MUST NOT break such systems. These are supported by @libuv/collaborators.
+
+* **Tier 2**: Officially supported, but not necessarily tested with CI. These
+  systems are maintained to the best of @libuv/collaborators ability,
+  without being a top priority.
+
+* **Tier 3**: Community maintained. These systems may inadvertently break and the
+  community and interested parties are expected to help with the maintenance.
+
+## Adding support for a new platform
+
+**IMPORTANT**: Before attempting to add support for a new platform please open
+an issue about it for discussion.
+
+### Unix
+
+I/O handling is abstracted by an internal `uv__io_t` handle. The new platform
+will need to implement some of the functions, the prototypes are in
+``src/unix/internal.h``.
+
+If the new platform requires extra fields for any handle structure, create a
+new include file in ``include/`` with the name ``uv-theplatform.h`` and add
+the appropriate defines there.
+
+All functionality related to the new platform must be implemented in its own
+file inside ``src/unix/`` unless it's already done in a common file, in which
+case adding an `ifdef` is fine.
+
+Two build systems are supported: autotools and cmake. Ideally both need to be
+supported, but if one of the two does not support the new platform it can be
+left out.
+
+### Windows
+
+Windows is treated as a single platform, so adding support for a new platform
+would mean adding support for a new version.
+
+Compilation and runtime must succeed for the minimum supported version. If a
+new API is to be used, it must be done optionally, only in supported versions.
+
+### Common
+
+Some common notes when adding support for new platforms:
+
+* Generally libuv tries to avoid compile time checks. Do not add any to the
+  autotools based build system or use version checking macros.
+  Dynamically load functions and symbols if they are not supported by the
+  minimum supported version.

+:c:type:`uv_async_t` --- Async handle
+=====================================
+
+Async handles allow the user to "wakeup" the event loop and get a callback
+called from another thread.
+
+
+Data types
+----------
+
+.. c:type:: uv_async_t
+
+    Async handle type.
+
+.. c:type:: void (*uv_async_cb)(uv_async_t* handle)
+
+    Type definition for callback passed to :c:func:`uv_async_init`.
+
+
+Public members

+
+
+API
+---
+
+.. c:function:: int uv_async_init(uv_loop_t* loop, uv_async_t* async, uv_async_cb async_cb)
+
+    Initialize the handle. A NULL callback is allowed.
+
+    :returns: 0 on success, or an error code < 0 on failure.
+
+    .. note::
+        Unlike other handle initialization  functions, it immediately starts the handle.
+
+.. c:function:: int uv_async_send(uv_async_t* async)
+
+    Wake up the event loop and call the async handle's callback.
+
+    :returns: 0 on success, or an error code < 0 on failure.
+
+    .. note::
+        It's safe to call this function from any thread. The callback will be called on the
+        loop thread.
+
+    .. note::
+        :c:func:`uv_async_send` is `async-signal-safe <https://man7.org/linux/man-pages/man7/signal-safety.7.html>`_.
+        It's safe to call this function from a signal handler.
+
+    .. warning::
+        libuv will coalesce calls to :c:func:`uv_async_send`, that is, not every call to it will
+        yield an execution of the callback. For example: if :c:func:`uv_async_send` is called 5
+        times in a row before the callback is called, the callback will only be called once. If
+        :c:func:`uv_async_send` is called again after the callback was called, it will be called
+        again.
+
+.. seealso::

+
+Design overview
+===============
+
+libuv is cross-platform support library which was originally written for `Node.js`_. It's designed
+around the event-driven asynchronous I/O model.
+
+.. _Node.js: https://nodejs.org
+
+The library provides much more than a simple abstraction over different I/O polling mechanisms:
+'handles' and 'streams' provide a high level abstraction for sockets and other entities;
+cross-platform file I/O and threading functionality is also provided, amongst other things.
+
+Here is a diagram illustrating the different parts that compose libuv and what subsystem they
+relate to:
+
+.. image:: static/architecture.png
+    :scale: 75%
+    :align: center
+
+
+Handles and requests
+^^^^^^^^^^^^^^^^^^^^
+
+libuv provides users with 2 abstractions to work with, in combination with the event loop:
+handles and requests.
+
+Handles represent long-lived objects capable of performing certain operations while active. Some examples:
+
+- A prepare handle gets its callback called once every loop iteration when active.
+- A TCP server handle that gets its connection callback called every time there is a new connection.
+
+Requests represent (typically) short-lived operations. These operations can be performed over a
+handle: write requests are used to write data on a handle; or standalone: getaddrinfo requests
+don't need a handle they run directly on the loop.
+
+
+The I/O loop
+^^^^^^^^^^^^
+
+The I/O (or event) loop is the central part of libuv. It establishes the content for all I/O
+operations, and it's meant to be tied to a single thread. One can run multiple event loops
+as long as each runs in a different thread. The libuv event loop (or any other API involving
+the loop or handles, for that matter) **is not thread-safe** except where stated otherwise.
+
+The event loop follows the rather usual single threaded asynchronous I/O approach: all (network)
+I/O is performed on non-blocking sockets which are polled using the best mechanism available
+on the given platform: epoll on Linux, kqueue on OSX and other BSDs, event ports on SunOS and IOCP
+on Windows. As part of a loop iteration the loop will block waiting for I/O activity on sockets
+which have been added to the poller and callbacks will be fired indicating socket conditions
+(readable, writable hangup) so handles can read, write or perform the desired I/O operation.
+
+In order to better understand how the event loop operates, the following diagram illustrates all
+stages of a loop iteration:
+
+.. image:: static/loop_iteration.png
+    :scale: 75%
+    :align: center
+
+
+#. The loop concept of 'now' is updated. The event loop caches the current time at the start of
+   the event loop tick in order to reduce the number of time-related system calls.
+
+#. If the loop is *alive*  an iteration is started, otherwise the loop will exit immediately. So,
+   when is a loop considered to be *alive*? If a loop has active and ref'd handles, active
+   requests or closing handles it's considered to be *alive*.
+
+#. Due timers are run. All active timers scheduled for a time before the loop's concept of *now*
+   get their callbacks called.
+
+#. Pending callbacks are called. All I/O callbacks are called right after polling for I/O, for the
+   most part. There are cases, however, in which calling such a callback is deferred for the next
+   loop iteration. If the previous iteration deferred any I/O callback it will be run at this point.
+
+#. Idle handle callbacks are called. Despite the unfortunate name, idle handles are run on every
+   loop iteration, if they are active.
+
+#. Prepare handle callbacks are called. Prepare handles get their callbacks called right before
+   the loop will block for I/O.
+
+#. Poll timeout is calculated. Before blocking for I/O the loop calculates for how long it should
+   block. These are the rules when calculating the timeout:
+
+        * If the loop was run with the ``UV_RUN_NOWAIT`` flag, the timeout is 0.
+        * If the loop is going to be stopped (:c:func:`uv_stop` was called), the timeout is 0.
+        * If there are no active handles or requests, the timeout is 0.
+        * If there are any idle handles active, the timeout is 0.
+        * If there are any handles pending to be closed, the timeout is 0.
+        * If none of the above cases matches, the timeout of the closest timer is taken, or
+          if there are no active timers, infinity.
+
+#. The loop blocks for I/O. At this point the loop will block for I/O for the duration calculated
+   in the previous step. All I/O related handles that were monitoring a given file descriptor
+   for a read or write operation get their callbacks called at this point.
+
+#. Check handle callbacks are called. Check handles get their callbacks called right after the
+   loop has blocked for I/O. Check handles are essentially the counterpart of prepare handles.
+
+#. Close callbacks are called. If a handle was closed by calling :c:func:`uv_close` it will
+   get the close callback called.
+
+#. Special case in case the loop was run with ``UV_RUN_ONCE``, as it implies forward progress.
+   It's possible that no I/O callbacks were fired after blocking for I/O, but some time has passed
+   so there might be timers which are due, those timers get their callbacks called.
+
+#. Iteration ends. If the loop was run with ``UV_RUN_NOWAIT`` or ``UV_RUN_ONCE`` modes the
+   iteration ends and :c:func:`uv_run` will return. If the loop was run with ``UV_RUN_DEFAULT``
+   it will continue from the start if it's still *alive*, otherwise it will also end.
+
+
+.. important::
+    libuv uses a thread pool to make asynchronous file I/O operations possible, but
+    network I/O is **always** performed in a single thread, each loop's thread.
+
+.. note::
+    While the polling mechanism is different, libuv makes the execution model consistent
+    across Unix systems and Windows.
+
+
+File I/O
+^^^^^^^^
+
+Unlike network I/O, there are no platform-specific file I/O primitives libuv could rely on,
+so the current approach is to run blocking file I/O operations in a thread pool.

+
+libuv currently uses a global thread pool on which all loops can queue work. 3 types of
+operations are currently run on this pool:
+
+    * File system operations
+    * DNS functions (getaddrinfo and getnameinfo)
+    * User specified code via :c:func:`uv_queue_work`
+
+.. warning::
+    See the :c:ref:`threadpool` section for more details, but keep in mind the thread pool size
+    is quite limited.

+Error handling
+==============
+
+In libuv errors are negative numbered constants. As a rule of thumb, whenever
+there is a status parameter, or an API functions returns an integer, a negative
+number will imply an error.
+
+When a function which takes a callback returns an error, the callback will never
+be called.
+
+.. note::
+    Implementation detail: on Unix error codes are the negated `errno` (or `-errno`), while on
+    Windows they are defined by libuv to arbitrary negative numbers.

+File system operations
+======================
+
+libuv provides a wide variety of cross-platform sync and async file system
+operations. All functions defined in this document take a callback, which is
+allowed to be NULL. If the callback is NULL the request is completed synchronously,
+otherwise it will be performed asynchronously.
+
+All file operations are run on the threadpool. See :ref:`threadpool` for information
+on the threadpool size.
+
+.. note::
+     On Windows `uv_fs_*` functions use utf-8 encoding.

+          must be spawned for each monitor for the same event.
+        - Events for file modification (writing to a file) are not received if only the
+          containing folder is watched.

+    See documentation_ for more details.

+About
+=====
+
+`Nikhil Marathe <https://nikhilism.com>`_ started writing this book one
+afternoon (June 16, 2012) when he didn't feel like programming. He had recently
+been stung by the lack of good documentation on libuv while working on
+`node-taglib <https://github.com/nikhilm/node-taglib>`_. Although reference
+documentation was present, there were no comprehensive tutorials. This book is
+the output of that need and tries to be accurate. That said, the book may have
+mistakes. Pull requests are encouraged.
+
+Nikhil is indebted to Marc Lehmann's comprehensive `man page
+<http://pod.tst.eu/http://cvs.schmorp.de/libev/ev.pod>`_ about libev which
+describes much of the semantics of the two libraries.
+
+This book was made using `Sphinx <https://www.sphinx-doc.org>`_ and `vim
+<https://www.vim.org>`_.
+
+.. note::
+    In 2017 the libuv project incorporated the Nikhil's work into the official
+    documentation and it's maintained there henceforth.

+Basics of libuv
+===============
+
+libuv enforces an **asynchronous**, **event-driven** style of programming.  Its
+core job is to provide an event loop and callback based notifications of I/O
+and other activities.  libuv offers core utilities like timers, non-blocking
+networking support, asynchronous file system access, child processes and more.
+
+Event loops
+-----------
+
+In event-driven programming, an application expresses interest in certain events
+and respond to them when they occur. The responsibility of gathering events
+from the operating system or monitoring other sources of events is handled by
+libuv, and the user can register callbacks to be invoked when an event occurs.
+The event-loop usually keeps running *forever*. In pseudocode:
+
+.. code-block:: python
+
+    while there are still events to process:
+        e = get the next event
+        if there is a callback associated with e:
+            call the callback
+
+Some examples of events are:
+
+* File is ready for writing
+* A socket has data ready to be read
+* A timer has timed out
+
+This event loop is encapsulated by ``uv_run()`` -- the end-all function when using
+libuv.
+
+The most common activity of systems programs is to deal with input and output,
+rather than a lot of number-crunching. The problem with using conventional
+input/output functions (``read``, ``fprintf``, etc.) is that they are
+**blocking**. The actual write to a hard disk or reading from a network, takes
+a disproportionately long time compared to the speed of the processor. The
+functions don't return until the task is done, so that your program is doing
+nothing. For programs which require high performance this is a major roadblock
+as other activities and other I/O operations are kept waiting.
+
+One of the standard solutions is to use threads. Each blocking I/O operation is
+started in a separate thread (or in a thread pool). When the blocking function
+gets invoked in the thread, the operating system can schedule another thread to run,
+which actually needs the CPU.
+
+The approach followed by libuv uses another style, which is the **asynchronous,
+non-blocking** style. Most modern operating systems provide event notification
+subsystems. For example, a normal ``read`` call on a socket would block until
+the sender actually sent something. Instead, the application can request the
+operating system to watch the socket and put an event notification in the
+queue. The application can inspect the events at its convenience (perhaps doing
+some number crunching before to use the processor to the maximum) and grab the
+data. It is **asynchronous** because the application expressed interest at one
+point, then used the data at another point (in time and space). It is
+**non-blocking** because the application process was free to do other tasks.
+This fits in well with libuv's event-loop approach, since the operating system
+events can be treated as just another libuv event. The non-blocking ensures
+that other events can continue to be handled as fast as they come in [#]_.
+
+.. NOTE::
+
+    How the I/O is run in the background is not of our concern, but due to the
+    way our computer hardware works, with the thread as the basic unit of the
+    processor, libuv and OSes will usually run background/worker threads and/or
+    polling to perform tasks in a non-blocking manner.
+
+Bert Belder, one of the libuv core developers has a small video explaining the
+architecture of libuv and its background. If you have no prior experience with
+either libuv or libev, it is a quick, useful watch.
+
+libuv's event loop is explained in more detail in the `documentation
+<https://docs.libuv.org/en/v1.x/design.html#the-i-o-loop>`_.

+    allowfullscreen></iframe>
+
+Hello World
+-----------
+
+With the basics out of the way, let's write our first libuv program. It does
+nothing, except start a loop which will exit immediately.
+
+.. rubric:: helloworld/main.c
+.. literalinclude:: ../../code/helloworld/main.c
+    :language: c
+    :linenos:
+
+This program quits immediately because it has no events to process. A libuv
+event loop has to be told to watch out for events using the various API
+functions.
+
+Starting with libuv v1.0, users should allocate the memory for the loops before
+initializing it with ``uv_loop_init(uv_loop_t *)``. This allows you to plug in
+custom memory management. Remember to de-initialize the loop using
+``uv_loop_close(uv_loop_t *)`` and then delete the storage. The examples never
+close loops since the program quits after the loop ends and the system will
+reclaim memory. Production grade projects, especially long running systems
+programs, should take care to release correctly.
+
+Default loop
+++++++++++++
+
+A default loop is provided by libuv and can be accessed using
+``uv_default_loop()``. You should use this loop if you only want a single
+loop.
+
+.. rubric:: default-loop/main.c
+.. literalinclude:: ../../code/default-loop/main.c
+    :language: c
+    :linenos:
+
+.. note::
+
+    node.js uses the default loop as its main loop. If you are writing bindings
+    you should be aware of this.
+
+.. _libuv-error-handling:
+
+Error handling
+--------------
+
+Initialization functions or synchronous functions which may fail return a negative number on error. Async functions that may fail will pass a status parameter to their callbacks. The error messages are defined as ``UV_E*`` `constants`_.
+
+.. _constants: https://docs.libuv.org/en/v1.x/errors.html#error-constants
+
+You can use the ``uv_strerror(int)`` and ``uv_err_name(int)`` functions
+to get a ``const char *`` describing the error or the error name respectively.
+
+I/O read callbacks (such as for files and sockets) are passed a parameter ``nread``. If ``nread`` is less than 0, there was an error (UV_EOF is the end of file error, which you may want to handle differently).
+
+Handles and Requests
+--------------------
+
+libuv works by the user expressing interest in particular events. This is
+usually done by creating a **handle** to an I/O device, timer or process.
+Handles are opaque structs named as ``uv_TYPE_t`` where type signifies what the
+handle is used for.
+
+.. rubric:: libuv watchers
+.. code-block:: c
+
+    /* Handle types. */
+    typedef struct uv_loop_s uv_loop_t;
+    typedef struct uv_handle_s uv_handle_t;
+    typedef struct uv_dir_s uv_dir_t;
+    typedef struct uv_stream_s uv_stream_t;
+    typedef struct uv_tcp_s uv_tcp_t;
+    typedef struct uv_udp_s uv_udp_t;
+    typedef struct uv_pipe_s uv_pipe_t;
+    typedef struct uv_tty_s uv_tty_t;
+    typedef struct uv_poll_s uv_poll_t;

+    typedef struct uv_check_s uv_check_t;

+    typedef struct uv_async_s uv_async_t;
+    typedef struct uv_process_s uv_process_t;
+    typedef struct uv_fs_event_s uv_fs_event_t;
+    typedef struct uv_fs_poll_s uv_fs_poll_t;
+    typedef struct uv_signal_s uv_signal_t;
+
+    /* Request types. */
+    typedef struct uv_req_s uv_req_t;
+    typedef struct uv_getaddrinfo_s uv_getaddrinfo_t;
+    typedef struct uv_getnameinfo_s uv_getnameinfo_t;
+    typedef struct uv_shutdown_s uv_shutdown_t;
+    typedef struct uv_write_s uv_write_t;
+    typedef struct uv_connect_s uv_connect_t;
+    typedef struct uv_udp_send_s uv_udp_send_t;
+    typedef struct uv_fs_s uv_fs_t;
+    typedef struct uv_work_s uv_work_t;
+    typedef struct uv_random_s uv_random_t;
+
+    /* None of the above. */
+    typedef struct uv_env_item_s uv_env_item_t;
+    typedef struct uv_cpu_info_s uv_cpu_info_t;
+    typedef struct uv_interface_address_s uv_interface_address_t;
+    typedef struct uv_dirent_s uv_dirent_t;
+    typedef struct uv_passwd_s uv_passwd_t;
+    typedef struct uv_utsname_s uv_utsname_t;
+    typedef struct uv_statfs_s uv_statfs_t;
+
+
+Handles represent long-lived objects. Async operations on such handles are
+identified using **requests**. A request is short-lived (usually used across
+only one callback) and usually indicates one I/O operation on a handle.
+Requests are used to preserve context between the initiation and the callback
+of individual actions. For example, an UDP socket is represented by
+a ``uv_udp_t``, while individual writes to the socket use a ``uv_udp_send_t``
+structure that is passed to the callback after the write is done.
+
+Handles are setup by a corresponding::
+
+    uv_TYPE_init(uv_loop_t *, uv_TYPE_t *)
+
+function.
+
+Callbacks are functions which are called by libuv whenever an event the watcher
+is interested in has taken place. Application specific logic will usually be
+implemented in the callback. For example, an IO watcher's callback will receive
+the data read from a file, a timer callback will be triggered on timeout and so
+on.
+
+Idling
+++++++
+
+Here is an example of using an idle handle. The callback is called once on
+every turn of the event loop. A use case for idle handles is discussed in
+:doc:`utilities`. Let us use an idle watcher to look at the watcher life cycle
+and see how ``uv_run()`` will now block because a watcher is present. The idle
+watcher is stopped when the count is reached and ``uv_run()`` exits since no
+event watchers are active.
+
+.. rubric:: idle-basic/main.c
+.. literalinclude:: ../../code/idle-basic/main.c
+    :language: c
+    :emphasize-lines: 6,10,14-17
+
+Storing context
++++++++++++++++
+
+In callback based programming style you'll often want to pass some 'context' --
+application specific information -- between the call site and the callback. All
+handles and requests have a ``void* data`` member which you can set to the
+context and cast back in the callback. This is a common pattern used throughout
+the C library ecosystem. In addition ``uv_loop_t`` also has a similar data
+member.

+Advanced event loops
+====================
+
+libuv provides considerable user control over event loops, and you can achieve
+interesting results by juggling multiple loops. You can also embed libuv's
+event loop into another event loop based library -- imagine a Qt based UI, and
+Qt's event loop driving a libuv backend which does intensive system level
+tasks.
+
+Stopping an event loop
+~~~~~~~~~~~~~~~~~~~~~~
+
+``uv_stop()`` can be used to stop an event loop. The earliest the loop will
+stop running is *on the next iteration*, possibly later. This means that events
+that are ready to be processed in this iteration of the loop will still be
+processed, so ``uv_stop()`` can't be used as a kill switch. When ``uv_stop()``
+is called, the loop **won't** block for i/o on this iteration. The semantics of
+these things can be a bit difficult to understand, so let's look at
+``uv_run()`` where all the control flow occurs.
+
+.. rubric:: src/unix/core.c - uv_run
+.. literalinclude:: ../../../src/unix/core.c
+    :language: c
+    :linenos:
+    :lines: 304-324
+    :emphasize-lines: 10,19,21
+
+``stop_flag`` is set by ``uv_stop()``. Now all libuv callbacks are invoked
+within the event loop, which is why invoking ``uv_stop()`` in them will still
+lead to this iteration of the loop occurring. First libuv updates timers, then
+runs pending timer, idle and prepare callbacks, and invokes any pending I/O
+callbacks. If you were to call ``uv_stop()`` in any of them, ``stop_flag``
+would be set. This causes ``uv_backend_timeout()`` to return ``0``, which is
+why the loop does not block on I/O. If on the other hand, you called
+``uv_stop()`` in one of the check handlers, I/O has already finished and is not
+affected.
+
+``uv_stop()`` is useful to shutdown a loop when a result has been computed or
+there is an error, without having to ensure that all handlers are stopped one
+by one.
+
+Here is a simple example that stops the loop and demonstrates how the current
+iteration of the loop still takes places.

+Filesystem
+==========
+
+Simple filesystem read/write is achieved using the ``uv_fs_*`` functions and the
+``uv_fs_t`` struct.
+
+.. note::
+
+    The libuv filesystem operations are different from :doc:`socket operations
+    <networking>`. Socket operations use the non-blocking operations provided
+    by the operating system. Filesystem operations use blocking functions
+    internally, but invoke these functions in a `thread pool`_ and notify
+    watchers registered with the event loop when application interaction is
+    required.
+
+.. _thread pool: https://docs.libuv.org/en/v1.x/threadpool.html#thread-pool-work-scheduling
+
+All filesystem functions have two forms - *synchronous* and *asynchronous*.
+
+The *synchronous* forms automatically get called (and **block**) if the
+callback is null. The return value of functions is a :ref:`libuv error code
+<libuv-error-handling>`. This is usually only useful for synchronous calls.
+The *asynchronous* form is called when a callback is passed and the return
+value is 0.
+
+Reading/Writing files
+---------------------
+
+A file descriptor is obtained using
+
+.. code-block:: c
+
+    int uv_fs_open(uv_loop_t* loop, uv_fs_t* req, const char* path, int flags, int mode, uv_fs_cb cb)
+
+``flags`` and ``mode`` are standard
+`Unix flags <https://man7.org/linux/man-pages/man2/open.2.html>`_.
+libuv takes care of converting to the appropriate Windows flags.
+
+File descriptors are closed using
+
+.. code-block:: c
+
+    int uv_fs_close(uv_loop_t* loop, uv_fs_t* req, uv_file file, uv_fs_cb cb)
+
+
+Filesystem operation callbacks have the signature:
+
+.. code-block:: c
+
+    void callback(uv_fs_t* req);
+
+Let's see a simple implementation of ``cat``. We start with registering
+a callback for when the file is opened:
+
+.. rubric:: uvcat/main.c - opening a file
+.. literalinclude:: ../../code/uvcat/main.c
+    :language: c
+    :linenos:
+    :lines: 41-53
+    :emphasize-lines: 4, 6-7
+
+The ``result`` field of a ``uv_fs_t`` is the file descriptor in case of the
+``uv_fs_open`` callback. If the file is successfully opened, we start reading it.
+
+.. rubric:: uvcat/main.c - read callback
+.. literalinclude:: ../../code/uvcat/main.c
+    :language: c
+    :linenos:
+    :lines: 26-39
+    :emphasize-lines: 2,8,12
+
+In the case of a read call, you should pass an *initialized* buffer which will
+be filled with data before the read callback is triggered. The ``uv_fs_*``
+operations map almost directly to certain POSIX functions, so EOF is indicated
+in this case by ``result`` being 0. In the case of streams or pipes, the
+``UV_EOF`` constant would have been passed as a status instead.
+
+Here you see a common pattern when writing asynchronous programs. The
+``uv_fs_close()`` call is performed synchronously. *Usually tasks which are
+one-off, or are done as part of the startup or shutdown stage are performed
+synchronously, since we are interested in fast I/O when the program is going
+about its primary task and dealing with multiple I/O sources*. For solo tasks
+the performance difference usually is negligible and may lead to simpler code.
+
+Filesystem writing is similarly simple using ``uv_fs_write()``.  *Your callback
+will be triggered after the write is complete*.  In our case the callback
+simply drives the next read. Thus read and write proceed in lockstep via
+callbacks.
+
+.. rubric:: uvcat/main.c - write callback
+.. literalinclude:: ../../code/uvcat/main.c
+    :language: c
+    :linenos:
+    :lines: 17-24
+    :emphasize-lines: 6
+
+.. warning::
+
+    Due to the way filesystems and disk drives are configured for performance,
+    a write that 'succeeds' may not be committed to disk yet.
+
+We set the dominos rolling in ``main()``:
+
+.. rubric:: uvcat/main.c
+.. literalinclude:: ../../code/uvcat/main.c
+    :language: c
+    :linenos:
+    :lines: 55-
+    :emphasize-lines: 2
+
+.. warning::
+
+    The ``uv_fs_req_cleanup()`` function must always be called on filesystem
+    requests to free internal memory allocations in libuv.
+
+Filesystem operations
+---------------------
+
+All the standard filesystem operations like ``unlink``, ``rmdir``, ``stat`` are
+supported asynchronously and have intuitive argument order. They follow the
+same patterns as the read/write/open calls, returning the result in the
+``uv_fs_t.result`` field. The full list:
+
+.. rubric:: Filesystem operations
+.. code-block:: c
+
+    int uv_fs_close(uv_loop_t* loop, uv_fs_t* req, uv_file file, uv_fs_cb cb);

+
+
+.. _buffers-and-streams:
+
+Buffers and Streams
+-------------------
+
+The basic I/O handle in libuv is the stream (``uv_stream_t``). TCP sockets, UDP
+sockets, and pipes for file I/O and IPC are all treated as stream subclasses.
+
+Streams are initialized using custom functions for each subclass, then operated
+upon using
+
+.. code-block:: c
+
+    int uv_read_start(uv_stream_t*, uv_alloc_cb alloc_cb, uv_read_cb read_cb);
+    int uv_read_stop(uv_stream_t*);
+    int uv_write(uv_write_t* req, uv_stream_t* handle,
+                 const uv_buf_t bufs[], unsigned int nbufs, uv_write_cb cb);
+
+The stream based functions are simpler to use than the filesystem ones and
+libuv will automatically keep reading from a stream when ``uv_read_start()`` is
+called once, until ``uv_read_stop()`` is called.
+
+The discrete unit of data is the buffer -- ``uv_buf_t``. This is simply
+a collection of a pointer to bytes (``uv_buf_t.base``) and the length
+(``uv_buf_t.len``). The ``uv_buf_t`` is lightweight and passed around by value.
+What does require management is the actual bytes, which have to be allocated
+and freed by the application.
+
+.. ERROR::
+
+    **THIS PROGRAM DOES NOT ALWAYS WORK, NEED SOMETHING BETTER**
+
+To demonstrate streams we will need to use ``uv_pipe_t``. This allows streaming
+local files [#]_. Here is a simple tee utility using libuv.  Doing all operations
+asynchronously shows the power of evented I/O. The two writes won't block each
+other, but we have to be careful to copy over the buffer data to ensure we don't
+free a buffer until it has been written.
+
+The program is to be executed as::
+
+    ./uvtee <output_file>
+
+We start off opening pipes on the files we require. libuv pipes to a file are
+opened as bidirectional by default.
+
+.. rubric:: uvtee/main.c - read on pipes
+.. literalinclude:: ../../code/uvtee/main.c
+    :language: c
+    :linenos:
+    :lines: 62-80
+    :emphasize-lines: 4,5,15
+
+The third argument of ``uv_pipe_init()`` should be set to 1 for IPC using named
+pipes. This is covered in :doc:`processes`. The ``uv_pipe_open()`` call
+associates the pipe with the file descriptor, in this case ``0`` (standard
+input).
+
+We start monitoring ``stdin``. The ``alloc_buffer`` callback is invoked as new
+buffers are required to hold incoming data. ``read_stdin`` will be called with
+these buffers.
+
+.. rubric:: uvtee/main.c - reading buffers
+.. literalinclude:: ../../code/uvtee/main.c
+    :language: c
+    :linenos:
+    :lines: 19-22,44-60
+
+The standard ``malloc`` is sufficient here, but you can use any memory allocation
+scheme. For example, node.js uses its own slab allocator which associates
+buffers with V8 objects.
+
+The read callback ``nread`` parameter is less than 0 on any error. This error
+might be EOF, in which case we close all the streams, using the generic close
+function ``uv_close()`` which deals with the handle based on its internal type.
+Otherwise ``nread`` is a non-negative number and we can attempt to write that
+many bytes to the output streams. Finally remember that buffer allocation and
+deallocation is application responsibility, so we free the data.
+
+The allocation callback may return a buffer with length zero if it fails to
+allocate memory. In this case, the read callback is invoked with error
+UV_ENOBUFS. libuv will continue to attempt to read the stream though, so you
+must explicitly call ``uv_close()`` if you want to stop when allocation fails.
+
+The read callback may be called with ``nread = 0``, indicating that at this
+point there is nothing to be read. Most applications will just ignore this.
+
+.. rubric:: uvtee/main.c - Write to pipe
+.. literalinclude:: ../../code/uvtee/main.c
+    :language: c
+    :linenos:
+    :lines: 9-13,23-42
+
+``write_data()`` makes a copy of the buffer obtained from read. This buffer
+does not get passed through to the write callback trigged on write completion. To
+get around this we wrap a write request and a buffer in ``write_req_t`` and
+unwrap it in the callbacks. We make a copy so we can free the two buffers from
+the two calls to ``write_data`` independently of each other. While acceptable
+for a demo program like this, you'll probably want smarter memory management,
+like reference counted buffers or a pool of buffers in any major application.
+
+.. WARNING::
+
+    If your program is meant to be used with other programs it may knowingly or
+    unknowingly be writing to a pipe. This makes it susceptible to `aborting on
+    receiving a SIGPIPE`_. It is a good idea to insert::
+
+        signal(SIGPIPE, SIG_IGN)
+
+    in the initialization stages of your application.

+
+File change events
+------------------
+
+All modern operating systems provide APIs to put watches on individual files or
+directories and be informed when the files are modified. libuv wraps common
+file change notification libraries [#fsnotify]_. This is one of the more
+inconsistent parts of libuv. File change notification systems are themselves
+extremely varied across platforms so getting everything working everywhere is
+difficult. To demonstrate, I'm going to build a simple utility which runs
+a command whenever any of the watched files change::
+
+    ./onchange <command> <file1> [file2] ...
+
+.. note::
+
+    Currently this example only works on OSX and Windows.
+    Refer to the `notes of uv_fs_event_start`_ function.
+
+.. _notes of uv_fs_event_start: https://docs.libuv.org/en/v1.x/fs_event.html#c.uv_fs_event_start
+
+The file change notification is started using ``uv_fs_event_init()``:
+
+.. rubric:: onchange/main.c - The setup
+.. literalinclude:: ../../code/onchange/main.c
+    :language: c
+    :linenos:
+    :lines: 26-
+    :emphasize-lines: 15
+
+The third argument is the actual file or directory to monitor. The last
+argument, ``flags``, can be:
+
+.. code-block:: c
+
+    /*
+     * Flags to be passed to uv_fs_event_start().
+     */
+    enum uv_fs_event_flags {
+        UV_FS_EVENT_WATCH_ENTRY = 1,
+        UV_FS_EVENT_STAT = 2,
+        UV_FS_EVENT_RECURSIVE = 4
+    };
+
+``UV_FS_EVENT_WATCH_ENTRY`` and ``UV_FS_EVENT_STAT`` don't do anything (yet).
+``UV_FS_EVENT_RECURSIVE`` will start watching subdirectories as well on
+supported platforms.
+
+The callback will receive the following arguments:
+
+  #. ``uv_fs_event_t *handle`` - The handle. The ``path`` field of the handle
+     is the file on which the watch was set.
+  #. ``const char *filename`` - If a directory is being monitored, this is the
+     file which was changed. Only non-``null`` on Linux and Windows. May be ``null``
+     even on those platforms.
+  #. ``int events`` - one of ``UV_RENAME`` or ``UV_CHANGE``, or a bitwise OR of
+     both.
+  #. ``int status`` - If ``status < 0``, there is an :ref:`libuv error<libuv-error-handling>`.
+
+In our example we simply print the arguments and run the command using

+Introduction
+============
+
+This 'book' is a small set of tutorials about using libuv_ as
+a high performance evented I/O library which offers the same API on Windows and Unix.
+
+It is meant to cover the main areas of libuv, but is not a comprehensive
+reference discussing every function and data structure. The `official libuv
+documentation`_ may be consulted for full details.
+
+.. _official libuv documentation: https://docs.libuv.org/en/v1.x/
+
+This book is still a work in progress, so sections may be incomplete, but
+I hope you will enjoy it as it grows.
+
+Who this book is for
+--------------------
+
+If you are reading this book, you are either:
+
+1) a systems programmer, creating low-level programs such as daemons or network
+   services and clients. You have found that the event loop approach is well
+   suited for your application and decided to use libuv.
+
+2) a node.js module writer, who wants to wrap platform APIs
+   written in C or C++ with a set of (a)synchronous APIs that are exposed to
+   JavaScript. You will use libuv purely in the context of node.js. For
+   this you will require some other resources as the book does not cover parts
+   specific to v8/node.js.
+
+This book assumes that you are comfortable with the C programming language.
+
+Background
+----------
+
+The node.js_ project began in 2009 as a JavaScript environment decoupled
+from the browser. Using Google's V8_ and Marc Lehmann's libev_, node.js
+combined a model of I/O -- evented -- with a language that was well suited to
+the style of programming; due to the way it had been shaped by browsers. As
+node.js grew in popularity, it was important to make it work on Windows, but
+libev ran only on Unix. The Windows equivalent of kernel event notification
+mechanisms like kqueue or (e)poll is IOCP. libuv was an abstraction around libev
+or IOCP depending on the platform, providing users an API based on libev.
+In the node-v0.9.0 version of libuv `libev was removed`_.
+
+Since then libuv has continued to mature and become a high quality standalone
+library for system programming. Users outside of node.js include Mozilla's
+Rust_ programming language, and a variety_ of language bindings.
+
+This book and the code is based on libuv version `v1.42.0`_.
+
+Code
+----
+
+All the example code and the source of the book is included as part of
+the libuv_ project on Github.
+Clone or Download libuv_, then build it::
+
+    sh autogen.sh
+    ./configure
+    make
+
+There is no need to ``make install``. To build the examples run ``make`` in the
+``docs/code/`` directory.

+Networking
+==========
+
+Networking in libuv is not much different from directly using the BSD socket
+interface, some things are easier, all are non-blocking, but the concepts stay
+the same. In addition libuv offers utility functions to abstract the annoying,
+repetitive and low-level tasks like setting up sockets using the BSD socket
+structures, DNS lookup, and tweaking various socket parameters.
+
+The ``uv_tcp_t`` and ``uv_udp_t`` structures are used for network I/O.
+
+.. NOTE::
+
+  The code samples in this chapter exist to show certain libuv APIs. They are
+  not examples of good quality code. They leak memory and don't always close
+  connections properly.
+
+TCP
+---
+
+TCP is a connection oriented, stream protocol and is therefore based on the
+libuv streams infrastructure.
+
+Server
+++++++
+
+Server sockets proceed by:
+
+1. ``uv_tcp_init`` the TCP handle.
+2. ``uv_tcp_bind`` it.
+3. Call ``uv_listen`` on the handle to have a callback invoked whenever a new
+   connection is established by a client.
+4. Use ``uv_accept`` to accept the connection.
+5. Use :ref:`stream operations <buffers-and-streams>` to communicate with the
+   client.
+
+Here is a simple echo server
+
+.. rubric:: tcp-echo-server/main.c - The listen socket
+.. literalinclude:: ../../code/tcp-echo-server/main.c
+    :language: c
+    :linenos:
+    :lines: 68-
+    :emphasize-lines: 4-5,7-10
+
+You can see the utility function ``uv_ip4_addr`` being used to convert from
+a human readable IP address, port pair to the sockaddr_in structure required by
+the BSD socket APIs. The reverse can be obtained using ``uv_ip4_name``.
+
+.. NOTE::
+
+    There are ``uv_ip6_*`` analogues for the ip4 functions.
+
+Most of the setup functions are synchronous since they are CPU-bound.
+``uv_listen`` is where we return to libuv's callback style. The second
+arguments is the backlog queue -- the maximum length of queued connections.
+
+When a connection is initiated by clients, the callback is required to set up
+a handle for the client socket and associate the handle using ``uv_accept``.
+In this case we also establish interest in reading from this stream.
+
+.. rubric:: tcp-echo-server/main.c - Accepting the client
+.. literalinclude:: ../../code/tcp-echo-server/main.c
+    :language: c
+    :linenos:
+    :lines: 51-66
+    :emphasize-lines: 9-10
+
+The remaining set of functions is very similar to the streams example and can
+be found in the code. Just remember to call ``uv_close`` when the socket isn't
+required. This can be done even in the ``uv_listen`` callback if you are not
+interested in accepting the connection.
+
+Client
+++++++
+
+Where you do bind/listen/accept on the server, on the client side it's simply
+a matter of calling ``uv_tcp_connect``. The same ``uv_connect_cb`` style
+callback of ``uv_listen`` is used by ``uv_tcp_connect``. Try::
+
+    uv_tcp_t* socket = (uv_tcp_t*)malloc(sizeof(uv_tcp_t));
+    uv_tcp_init(loop, socket);
+
+    uv_connect_t* connect = (uv_connect_t*)malloc(sizeof(uv_connect_t));
+
+    struct sockaddr_in dest;
+    uv_ip4_addr("127.0.0.1", 80, &dest);
+
+    uv_tcp_connect(connect, socket, (const struct sockaddr*)&dest, on_connect);
+
+where ``on_connect`` will be called after the connection is established. The
+callback receives the ``uv_connect_t`` struct, which has a member ``.handle``
+pointing to the socket.
+
+UDP
+---
+
+The `User Datagram Protocol`_ offers connectionless, unreliable network
+communication. Hence libuv doesn't offer a stream. Instead libuv provides
+non-blocking UDP support via the `uv_udp_t` handle (for receiving) and
+`uv_udp_send_t` request (for sending) and related functions. That said, the
+actual API for reading/writing is very similar to normal stream reads. To look
+at how UDP can be used, the example shows the first stage of obtaining an IP
+address from a `DHCP`_ server -- DHCP Discover.
+
+.. note::
+
+    You will have to run `udp-dhcp` as **root** since it uses well known port
+    numbers below 1024.
+
+.. rubric:: udp-dhcp/main.c - Setup and send UDP packets
+.. literalinclude:: ../../code/udp-dhcp/main.c
+    :language: c
+    :linenos:
+    :lines: 7-11,104-
+    :emphasize-lines: 8,10-11,17-18,21
+
+.. note::
+
+    The IP address ``0.0.0.0`` is used to bind to all interfaces. The IP
+    address ``255.255.255.255`` is a broadcast address meaning that packets
+    will be sent to all interfaces on the subnet.  port ``0`` means that the OS
+    randomly assigns a port.
+
+First we setup the receiving socket to bind on all interfaces on port 68 (DHCP
+client) and start a read on it. This will read back responses from any DHCP
+server that replies. We use the UV_UDP_REUSEADDR flag to play nice with any
+other system DHCP clients that are running on this computer on the same port.
+Then we setup a similar send socket and use ``uv_udp_send`` to send
+a *broadcast message* on port 67 (DHCP server).
+
+It is **necessary** to set the broadcast flag, otherwise you will get an
+``EACCES`` error [#]_. The exact message being sent is not relevant to this
+book and you can study the code if you are interested. As usual the read and
+write callbacks will receive a status code of < 0 if something went wrong.
+
+Since UDP sockets are not connected to a particular peer, the read callback
+receives an extra parameter about the sender of the packet.
+
+``nread`` may be zero if there is no more data to be read. If ``addr`` is NULL,
+it indicates there is nothing to read (the callback shouldn't do anything), if
+not NULL, it indicates that an empty datagram was received from the host at
+``addr``. The ``flags`` parameter may be ``UV_UDP_PARTIAL`` if the buffer
+provided by your allocator was not large enough to hold the data. *In this case
+the OS will discard the data that could not fit* (That's UDP for you!).

+
+UDP Options
++++++++++++
+
+Time-to-live
+~~~~~~~~~~~~
+
+The TTL of packets sent on the socket can be changed using ``uv_udp_set_ttl``.
+
+IPv6 stack only
+~~~~~~~~~~~~~~~
+
+IPv6 sockets can be used for both IPv4 and IPv6 communication. If you want to
+restrict the socket to IPv6 only, pass the ``UV_UDP_IPV6ONLY`` flag to
+``uv_udp_bind`` [#]_.
+
+Multicast
+~~~~~~~~~
+
+A socket can (un)subscribe to a multicast group using:
+
+.. code::block:: c
+
+    int uv_udp_set_membership(uv_udp_t* handle, const char* multicast_addr, const char* interface_addr, uv_membership membership);
+
+where ``membership`` is ``UV_JOIN_GROUP`` or ``UV_LEAVE_GROUP``.
+
+The concepts of multicasting are nicely explained in `this guide`_.
+
+.. _this guide: https://www.tldp.org/HOWTO/Multicast-HOWTO-2.html
+
+Local loopback of multicast packets is enabled by default [#]_, use
+``uv_udp_set_multicast_loop`` to switch it off.
+
+The packet time-to-live for multicast packets can be changed using
+``uv_udp_set_multicast_ttl``.
+
+Querying DNS
+------------
+
+libuv provides asynchronous DNS resolution. For this it provides its own
+``getaddrinfo`` replacement [#]_. In the callback you can
+perform normal socket operations on the retrieved addresses. Let's connect to
+Libera.chat to see an example of DNS resolution.
+
+.. rubric:: dns/main.c
+.. literalinclude:: ../../code/dns/main.c
+    :language: c
+    :linenos:
+    :lines: 61-
+    :emphasize-lines: 12
+
+If ``uv_getaddrinfo`` returns non-zero, something went wrong in the setup and
+your callback won't be invoked at all. All arguments can be freed immediately
+after ``uv_getaddrinfo`` returns. The `hostname`, `servname` and `hints`
+structures are documented in `the getaddrinfo man page <getaddrinfo_>`_. The
+callback can be ``NULL`` in which case the function will run synchronously.
+
+In the resolver callback, you can pick any IP from the linked list of ``struct
+addrinfo(s)``. This also demonstrates ``uv_tcp_connect``. It is necessary to
+call ``uv_freeaddrinfo`` in the callback.
+
+.. rubric:: dns/main.c
+.. literalinclude:: ../../code/dns/main.c
+    :language: c
+    :linenos:
+    :lines: 42-60
+    :emphasize-lines: 8,16
+
+libuv also provides the inverse `uv_getnameinfo`_.
+
+.. _uv_getnameinfo: http://docs.libuv.org/en/v1.x/dns.html#c.uv_getnameinfo
+
+Network interfaces
+------------------
+
+Information about the system's network interfaces can be obtained through libuv
+using ``uv_interface_addresses``. This simple program just prints out all the
+interface details so you get an idea of the fields that are available. This is
+useful to allow your service to bind to IP addresses when it starts.
+
+.. rubric:: interfaces/main.c
+.. literalinclude:: ../../code/interfaces/main.c
+    :language: c
+    :linenos:
+    :emphasize-lines: 9,17
+
+``is_internal`` is true for loopback interfaces. Note that if a physical
+interface has multiple IPv4/IPv6 addresses, the name will be reported multiple
+times, with each address being reported once.

+Processes
+=========
+
+libuv offers considerable child process management, abstracting the platform
+differences and allowing communication with the child process using streams or
+named pipes.
+
+A common idiom in Unix is for every process to do one thing and do it well. In
+such a case, a process often uses multiple child processes to achieve tasks
+(similar to using pipes in shells). A multi-process model with messages
+may also be easier to reason about compared to one with threads and shared
+memory.
+
+A common refrain against event-based programs is that they cannot take
+advantage of multiple cores in modern computers. In a multi-threaded program
+the kernel can perform scheduling and assign different threads to different
+cores, improving performance. But an event loop has only one thread.  The
+workaround can be to launch multiple processes instead, with each process
+running an event loop, and each process getting assigned to a separate CPU
+core.
+
+Spawning child processes
+------------------------
+
+The simplest case is when you simply want to launch a process and know when it
+exits. This is achieved using ``uv_spawn``.
+
+.. rubric:: spawn/main.c
+.. literalinclude:: ../../code/spawn/main.c
+    :language: c
+    :linenos:
+    :lines: 6-8,15-
+    :emphasize-lines: 11,13-17
+
+.. NOTE::
+
+    ``options`` is implicitly initialized with zeros since it is a global
+    variable.  If you change ``options`` to a local variable, remember to
+    initialize it to null out all unused fields::
+
+        uv_process_options_t options = {0};
+
+The ``uv_process_t`` struct only acts as the handle, all options are set via
+``uv_process_options_t``. To simply launch a process, you need to set only the
+``file`` and ``args`` fields. ``file`` is the program to execute. Since
+``uv_spawn`` uses :man:`execvp(3)` internally, there is no need to supply the full
+path. Finally as per underlying conventions, **the arguments array has to be
+one larger than the number of arguments, with the last element being NULL**.
+
+After the call to ``uv_spawn``, ``uv_process_t.pid`` will contain the process
+ID of the child process.
+
+The exit callback will be invoked with the *exit status* and the type of *signal*
+which caused the exit.
+
+.. rubric:: spawn/main.c
+.. literalinclude:: ../../code/spawn/main.c
+    :language: c
+    :linenos:
+    :lines: 9-12
+    :emphasize-lines: 3
+
+It is **required** to close the process watcher after the process exits.
+
+Changing process parameters
+---------------------------
+
+Before the child process is launched you can control the execution environment
+using fields in ``uv_process_options_t``.
+
+Change execution directory
+++++++++++++++++++++++++++
+
+Set ``uv_process_options_t.cwd`` to the corresponding directory.
+
+Set environment variables
++++++++++++++++++++++++++
+
+``uv_process_options_t.env`` is a null-terminated array of strings, each of the
+form ``VAR=VALUE`` used to set up the environment variables for the process. Set
+this to ``NULL`` to inherit the environment from the parent (this) process.
+
+Option flags
+++++++++++++
+
+Setting ``uv_process_options_t.flags`` to a bitwise OR of the following flags,
+modifies the child process behaviour:
+
+* ``UV_PROCESS_SETUID`` - sets the child's execution user ID to ``uv_process_options_t.uid``.
+* ``UV_PROCESS_SETGID`` - sets the child's execution group ID to ``uv_process_options_t.gid``.
+
+Changing the UID/GID is only supported on Unix, ``uv_spawn`` will fail on
+Windows with ``UV_ENOTSUP``.
+
+* ``UV_PROCESS_WINDOWS_VERBATIM_ARGUMENTS`` - No quoting or escaping of
+  ``uv_process_options_t.args`` is done on Windows. Ignored on Unix.
+* ``UV_PROCESS_DETACHED`` - Starts the child process in a new session, which
+  will keep running after the parent process exits. See example below.
+
+Detaching processes
+-------------------
+
+Passing the flag ``UV_PROCESS_DETACHED`` can be used to launch daemons, or
+child processes which are independent of the parent so that the parent exiting
+does not affect it.
+
+.. rubric:: detach/main.c
+.. literalinclude:: ../../code/detach/main.c
+    :language: c
+    :linenos:
+    :lines: 9-30
+    :emphasize-lines: 12,19
+
+Just remember that the handle is still monitoring the child, so your program
+won't exit. Use ``uv_unref()`` if you want to be more *fire-and-forget*.
+
+Sending signals to processes
+----------------------------
+
+libuv wraps the standard ``kill(2)`` system call on Unix and implements one
+with similar semantics on Windows, with *one caveat*: all of ``SIGTERM``,
+``SIGINT`` and ``SIGKILL``, lead to termination of the process. The signature
+of ``uv_kill`` is::
+
+    uv_err_t uv_kill(int pid, int signum);
+
+For processes started using libuv, you may use ``uv_process_kill`` instead,
+which accepts the ``uv_process_t`` watcher as the first argument, rather than
+the pid. In this case, **remember to call** ``uv_close`` on the watcher.
+
+Signals
+-------
+
+libuv provides wrappers around Unix signals with `some Windows support
+<http://docs.libuv.org/en/v1.x/signal.html#signal>`_ as well.
+
+Use ``uv_signal_init()`` to initialize
+a handle and associate it with a loop. To listen for particular signals on
+that handler, use ``uv_signal_start()`` with the handler function. Each handler
+can only be associated with one signal number, with subsequent calls to
+``uv_signal_start()`` overwriting earlier associations. Use ``uv_signal_stop()`` to
+stop watching. Here is a small example demonstrating the various possibilities:
+
+.. rubric:: signal/main.c
+.. literalinclude:: ../../code/signal/main.c
+    :language: c
+    :linenos:
+    :emphasize-lines: 17-18,27-28
+
+.. NOTE::
+
+    ``uv_run(loop, UV_RUN_NOWAIT)`` is similar to ``uv_run(loop, UV_RUN_ONCE)``
+    in that it will process only one event. UV_RUN_ONCE blocks if there are no
+    pending events, while UV_RUN_NOWAIT will return immediately. We use NOWAIT
+    so that one of the loops isn't starved because the other one has no pending
+    activity.
+
+Send ``SIGUSR1`` to the process, and you'll find the handler being invoked
+4 times, one for each ``uv_signal_t``. The handler just stops each handle,
+so that the program exits. This sort of dispatch to all handlers is very
+useful. A server using multiple event loops could ensure that all data was
+safely saved before termination, simply by every loop adding a watcher for
+``SIGINT``.
+
+Child Process I/O
+-----------------
+
+A normal, newly spawned process has its own set of file descriptors, with 0,
+1 and 2 being ``stdin``, ``stdout`` and ``stderr`` respectively. Sometimes you
+may want to share file descriptors with the child. For example, perhaps your
+applications launches a sub-command and you want any errors to go in the log
+file, but ignore ``stdout``. For this you'd like to have ``stderr`` of the
+child be the same as the stderr of the parent. In this case, libuv supports
+*inheriting* file descriptors. In this sample, we invoke the test program,
+which is:
+
+.. rubric:: proc-streams/test.c
+.. literalinclude:: ../../code/proc-streams/test.c
+    :language: c
+
+The actual program ``proc-streams`` runs this while sharing only ``stderr``.
+The file descriptors of the child process are set using the ``stdio`` field in
+``uv_process_options_t``. First set the ``stdio_count`` field to the number of
+file descriptors being set. ``uv_process_options_t.stdio`` is an array of
+``uv_stdio_container_t``, which is:
+
+.. code-block:: c
+
+    typedef struct uv_stdio_container_s {
+        uv_stdio_flags flags;
+
+        union {
+            uv_stream_t* stream;
+            int fd;
+        } data;
+    } uv_stdio_container_t;
+
+where flags can have several values. Use ``UV_IGNORE`` if it isn't going to be
+used. If the first three ``stdio`` fields are marked as ``UV_IGNORE`` they'll
+redirect to ``/dev/null``.
+
+Since we want to pass on an existing descriptor, we'll use ``UV_INHERIT_FD``.
+Then we set the ``fd`` to ``stderr``.
+
+.. rubric:: proc-streams/main.c
+.. literalinclude:: ../../code/proc-streams/main.c
+    :language: c
+    :linenos:
+    :lines: 15-17,27-
+    :emphasize-lines: 6,10,11,12
+
+If you run ``proc-stream`` you'll see that only the line "This is stderr" will
+be displayed. Try marking ``stdout`` as being inherited and see the output.
+
+It is dead simple to apply this redirection to streams.  By setting ``flags``
+to ``UV_INHERIT_STREAM`` and setting ``data.stream`` to the stream in the
+parent process, the child process can treat that stream as standard I/O. This
+can be used to implement something like CGI_.
+
+.. _CGI: https://en.wikipedia.org/wiki/Common_Gateway_Interface
+
+A sample CGI script/executable is:
+
+.. rubric:: cgi/tick.c
+.. literalinclude:: ../../code/cgi/tick.c
+    :language: c
+
+The CGI server combines the concepts from this chapter and :doc:`networking` so
+that every client is sent ten ticks after which that connection is closed.
+
+.. rubric:: cgi/main.c
+.. literalinclude:: ../../code/cgi/main.c
+    :language: c
+    :linenos:
+    :lines: 49-63
+    :emphasize-lines: 10
+
+Here we simply accept the TCP connection and pass on the socket (*stream*) to
+``invoke_cgi_script``.
+
+.. rubric:: cgi/main.c
+.. literalinclude:: ../../code/cgi/main.c
+    :language: c
+    :linenos:
+    :lines: 16, 25-45
+    :emphasize-lines: 8-9,18,20
+
+The ``stdout`` of the CGI script is set to the socket so that whatever our tick
+script prints, gets sent to the client. By using processes, we can offload the
+read/write buffering to the operating system, so in terms of convenience this
+is great. Just be warned that creating processes is a costly task.
+
+.. _pipes:
+
+Parent-child IPC
+----------------
+
+A parent and child can have one or two way communication over a pipe created by
+settings ``uv_stdio_container_t.flags`` to a bit-wise combination of
+``UV_CREATE_PIPE`` and ``UV_READABLE_PIPE`` or ``UV_WRITABLE_PIPE``. The
+read/write flag is from the perspective of the child process.  In this case,
+the ``uv_stream_t* stream`` field must be set to point to an initialized,
+unopened ``uv_pipe_t`` instance.
+
+New stdio Pipes
++++++++++++++++
+
+The ``uv_pipe_t`` structure represents more than just `pipe(7)`_ (or ``|``),
+but supports any streaming file-like objects. On Windows, the only object of
+that description is the `Named Pipe`_.  On Unix, this could be any of `Unix
+Domain Socket`_, or derived from `mkfifo(1)`_, or it could actually be a
+`pipe(7)`_.  When ``uv_spawn`` initializes a ``uv_pipe_t`` due to the
+`UV_CREATE_PIPE` flag, it opts for creating a `socketpair(2)`_.
+
+This is intended for the purpose of allowing multiple libuv processes to
+communicate with IPC. This is discussed below.
+
+.. _pipe(7): https://man7.org/linux/man-pages/man7/pipe.7.html
+.. _mkfifo(1): https://man7.org/linux/man-pages/man1/mkfifo.1.html

+.. _Unix Domain Socket: https://man7.org/linux/man-pages/man7/unix.7.html
+.. _Named Pipe: https://docs.microsoft.com/en-us/windows/win32/ipc/named-pipes
+
+
+Arbitrary process IPC
++++++++++++++++++++++
+
+Since domain sockets [#]_ can have a well known name and a location in the
+file-system they can be used for IPC between unrelated processes. The D-BUS_
+system used by open source desktop environments uses domain sockets for event
+notification. Various applications can then react when a contact comes online
+or new hardware is detected. The MySQL server also runs a domain socket on
+which clients can interact with it.
+
+.. _D-BUS: https://www.freedesktop.org/wiki/Software/dbus
+
+When using domain sockets, a client-server pattern is usually followed with the
+creator/owner of the socket acting as the server. After the initial setup,
+messaging is no different from TCP, so we'll re-use the echo server example.
+
+.. rubric:: pipe-echo-server/main.c
+.. literalinclude:: ../../code/pipe-echo-server/main.c
+    :language: c
+    :linenos:
+    :lines: 70-
+    :emphasize-lines: 5,10,14
+
+We name the socket ``echo.sock`` which means it will be created in the local
+directory. This socket now behaves no different from TCP sockets as far as
+the stream API is concerned. You can test this server using `socat`_::
+
+    $ socat - /path/to/socket
+
+A client which wants to connect to a domain socket will use::
+
+    void uv_pipe_connect(uv_connect_t *req, uv_pipe_t *handle, const char *name, uv_connect_cb cb);
+
+where ``name`` will be ``echo.sock`` or similar. On Unix systems, ``name`` must
+point to a valid file (e.g. ``/tmp/echo.sock``). On Windows, ``name`` follows a
+``\\?\pipe\echo.sock`` format.
+
+.. _socat: http://www.dest-unreach.org/socat/
+
+Sending file descriptors over pipes
++++++++++++++++++++++++++++++++++++
+
+The cool thing about domain sockets is that file descriptors can be exchanged
+between processes by sending them over a domain socket. This allows processes
+to hand off their I/O to other processes. Applications include load-balancing
+servers, worker processes and other ways to make optimum use of CPU. libuv only
+supports sending **TCP sockets or other pipes** over pipes for now.
+
+To demonstrate, we will look at a echo server implementation that hands of
+clients to worker processes in a round-robin fashion. This program is a bit
+involved, and while only snippets are included in the book, it is recommended
+to read the full code to really understand it.
+
+The worker process is quite simple, since the file-descriptor is handed over to
+it by the master.
+
+.. rubric:: multi-echo-server/worker.c
+.. literalinclude:: ../../code/multi-echo-server/worker.c
+    :language: c
+    :linenos:
+    :lines: 7-9,81-
+    :emphasize-lines: 6-8
+
+``queue`` is the pipe connected to the master process on the other end, along
+which new file descriptors get sent. It is important to set the ``ipc``
+argument of ``uv_pipe_init`` to 1 to indicate this pipe will be used for
+inter-process communication! Since the master will write the file handle to the
+standard input of the worker, we connect the pipe to ``stdin`` using
+``uv_pipe_open``.
+
+.. rubric:: multi-echo-server/worker.c
+.. literalinclude:: ../../code/multi-echo-server/worker.c
+    :language: c
+    :linenos:
+    :lines: 51-79
+    :emphasize-lines: 10,15,20
+
+First we call ``uv_pipe_pending_count()`` to ensure that a handle is available
+to read out. If your program could deal with different types of handles,
+``uv_pipe_pending_type()`` can be used to determine the type.
+Although ``accept`` seems odd in this code, it actually makes sense. What
+``accept`` traditionally does is get a file descriptor (the client) from
+another file descriptor (The listening socket). Which is exactly what we do
+here. Fetch the file descriptor (``client``) from ``queue``. From this point
+the worker does standard echo server stuff.
+
+Turning now to the master, let's take a look at how the workers are launched to
+allow load balancing.
+
+.. rubric:: multi-echo-server/main.c
+.. literalinclude:: ../../code/multi-echo-server/main.c
+    :language: c
+    :linenos:
+    :lines: 9-13
+
+The ``child_worker`` structure wraps the process, and the pipe between the
+master and the individual process.
+
+.. rubric:: multi-echo-server/main.c
+.. literalinclude:: ../../code/multi-echo-server/main.c
+    :language: c
+    :linenos:
+    :lines: 51,61-95
+    :emphasize-lines: 17,20-21
+
+In setting up the workers, we use the nifty libuv function ``uv_cpu_info`` to
+get the number of CPUs so we can launch an equal number of workers. Again it is
+important to initialize the pipe acting as the IPC channel with the third
+argument as 1. We then indicate that the child process' ``stdin`` is to be
+a readable pipe (from the point of view of the child). Everything is
+straightforward till here. The workers are launched and waiting for file
+descriptors to be written to their standard input.
+
+It is in ``on_new_connection`` (the TCP infrastructure is initialized in
+``main()``), that we accept the client socket and pass it along to the next
+worker in the round-robin.
+
+.. rubric:: multi-echo-server/main.c

+    :language: c
+    :linenos:
+    :lines: 31-49
+    :emphasize-lines: 9,12-13
+
+The ``uv_write2`` call handles all the abstraction and it is simply a matter of
+passing in the handle (``client``) as the right argument. With this our
+multi-process echo server is operational.
+
+Thanks to Kyle for `pointing out`_ that ``uv_write2()`` requires a non-empty
+buffer even when sending handles.

+Threads
+=======
+
+Wait a minute? Why are we on threads? Aren't event loops supposed to be **the
+way** to do *web-scale programming*? Well... no. Threads are still the medium in
+which processors do their jobs. Threads are therefore mighty useful sometimes, even
+though you might have to wade through various synchronization primitives.
+
+Threads are used internally to fake the asynchronous nature of all of the system
+calls. libuv also uses threads to allow you, the application, to perform a task
+asynchronously that is actually blocking, by spawning a thread and collecting
+the result when it is done.
+
+Today there are two predominant thread libraries: the Windows threads
+implementation and POSIX's :man:`pthreads(7)`. libuv's thread API is analogous to
+the pthreads API and often has similar semantics.
+
+A notable aspect of libuv's thread facilities is that it is a self contained
+section within libuv. Whereas other features intimately depend on the event
+loop and callback principles, threads are complete agnostic, they block as
+required, signal errors directly via return values, and, as shown in the
+:ref:`first example <thread-create-example>`, don't even require a running
+event loop.
+
+libuv's thread API is also very limited since the semantics and syntax of
+threads are different on all platforms, with different levels of completeness.
+
+This chapter makes the following assumption: **There is only one event loop,
+running in one thread (the main thread)**. No other thread interacts
+with the event loop (except using ``uv_async_send``).
+
+Core thread operations
+----------------------
+
+There isn't much here, you just start a thread using ``uv_thread_create()`` and
+wait for it to close using ``uv_thread_join()``.
+
+.. _thread-create-example:
+
+.. rubric:: thread-create/main.c
+.. literalinclude:: ../../code/thread-create/main.c
+    :language: c
+    :linenos:
+    :lines: 26-36
+    :emphasize-lines: 3-7
+
+.. tip::
+
+    ``uv_thread_t`` is just an alias for ``pthread_t`` on Unix, but this is an
+    implementation detail, avoid depending on it to always be true.
+
+The second parameter is the function which will serve as the entry point for
+the thread, the last parameter is a ``void *`` argument which can be used to pass
+custom parameters to the thread. The function ``hare`` will now run in a separate
+thread, scheduled pre-emptively by the operating system:
+
+.. rubric:: thread-create/main.c
+.. literalinclude:: ../../code/thread-create/main.c
+    :language: c
+    :linenos:
+    :lines: 6-14
+    :emphasize-lines: 2
+
+Unlike ``pthread_join()`` which allows the target thread to pass back a value to
+the calling thread using a second parameter, ``uv_thread_join()`` does not. To
+send values use :ref:`inter-thread-communication`.
+
+Synchronization Primitives
+--------------------------
+
+This section is purposely spartan. This book is not about threads, so I only
+catalogue any surprises in the libuv APIs here. For the rest you can look at
+the :man:`pthreads(7)` man pages.
+
+Mutexes
+~~~~~~~
+
+The mutex functions are a **direct** map to the pthread equivalents.
+
+.. rubric:: libuv mutex functions
+.. code-block:: c
+
+    int uv_mutex_init(uv_mutex_t* handle);
+    int uv_mutex_init_recursive(uv_mutex_t* handle);
+    void uv_mutex_destroy(uv_mutex_t* handle);
+    void uv_mutex_lock(uv_mutex_t* handle);
+    int uv_mutex_trylock(uv_mutex_t* handle);
+    void uv_mutex_unlock(uv_mutex_t* handle);
+
+The ``uv_mutex_init()``, ``uv_mutex_init_recursive()`` and ``uv_mutex_trylock()``
+functions will return 0 on success, and an error code otherwise.
+
+If `libuv` has been compiled with debugging enabled, ``uv_mutex_destroy()``,
+``uv_mutex_lock()`` and ``uv_mutex_unlock()`` will ``abort()`` on error.
+Similarly ``uv_mutex_trylock()`` will abort if the error is anything *other
+than* ``EAGAIN`` or ``EBUSY``.
+
+Recursive mutexes are supported, but you should not rely on them. Also, they
+should not be used with ``uv_cond_t`` variables.
+
+The default BSD mutex implementation will raise an error if a thread which has
+locked a mutex attempts to lock it again. For example, a construct like::
+
+    uv_mutex_init(a_mutex);
+    uv_mutex_lock(a_mutex);
+    uv_thread_create(thread_id, entry, (void *)a_mutex);
+    uv_mutex_lock(a_mutex);
+    // more things here
+
+can be used to wait until another thread initializes some stuff and then
+unlocks ``a_mutex`` but will lead to your program crashing if in debug mode, or
+return an error in the second call to ``uv_mutex_lock()``.
+
+.. note::
+
+    Mutexes on Windows are always recursive.
+
+Locks
+~~~~~
+
+Read-write locks are a more granular access mechanism. Two readers can access
+shared memory at the same time. A writer may not acquire the lock when it is
+held by a reader. A reader or writer may not acquire a lock when a writer is
+holding it. Read-write locks are frequently used in databases. Here is a toy
+example.
+
+.. rubric:: locks/main.c - simple rwlocks
+.. literalinclude:: ../../code/locks/main.c
+    :language: c
+    :linenos:
+    :emphasize-lines: 13,16,27,31,42,55
+
+Run this and observe how the readers will sometimes overlap. In case of
+multiple writers, schedulers will usually give them higher priority, so if you
+add two writers, you'll see that both writers tend to finish first before the
+readers get a chance again.
+
+We also use barriers in the above example so that the main thread can wait for
+all readers and writers to indicate they have ended.
+
+Others
+~~~~~~
+
+libuv also supports semaphores_, `condition variables`_ and barriers_ with APIs
+very similar to their pthread counterparts.
+
+.. _semaphores: https://en.wikipedia.org/wiki/Semaphore_(programming)
+.. _condition variables: https://en.wikipedia.org/wiki/Monitor_(synchronization)#Condition_variables_2
+.. _barriers: https://en.wikipedia.org/wiki/Barrier_(computer_science)
+
+In addition, libuv provides a convenience function ``uv_once()``. Multiple
+threads can attempt to call ``uv_once()`` with a given guard and a function
+pointer, **only the first one will win, the function will be called once and
+only once**::
+
+    /* Initialize guard */
+    static uv_once_t once_only = UV_ONCE_INIT;
+
+    int i = 0;
+
+    void increment() {
+        i++;
+    }
+
+    void thread1() {
+        /* ... work */
+        uv_once(once_only, increment);
+    }
+
+    void thread2() {
+        /* ... work */
+        uv_once(once_only, increment);
+    }
+
+    int main() {
+        /* ... spawn threads */
+    }
+
+After all threads are done, ``i == 1``.
+
+.. _libuv-work-queue:
+
+libuv v0.11.11 onwards also added a ``uv_key_t`` struct and api_ for
+thread-local storage.
+
+.. _api: http://docs.libuv.org/en/v1.x/threading.html#thread-local-storage
+
+libuv work queue
+----------------
+
+``uv_queue_work()`` is a convenience function that allows an application to run
+a task in a separate thread, and have a callback that is triggered when the
+task is done. A seemingly simple function, what makes ``uv_queue_work()``
+tempting is that it allows potentially any third-party libraries to be used
+with the event-loop paradigm. When you use event loops, it is *imperative to
+make sure that no function which runs periodically in the loop thread blocks
+when performing I/O or is a serious CPU hog*, because this means that the loop
+slows down and events are not being handled at full capacity.
+
+However, a lot of existing code out there features blocking functions (for example
+a routine which performs I/O under the hood) to be used with threads if you
+want responsiveness (the classic 'one thread per client' server model), and
+getting them to play with an event loop library generally involves rolling your
+own system of running the task in a separate thread.  libuv just provides
+a convenient abstraction for this.
+
+Here is a simple example inspired by `node.js is cancer`_. We are going to
+calculate fibonacci numbers, sleeping a bit along the way, but run it in
+a separate thread so that the blocking and CPU bound task does not prevent the
+event loop from performing other activities.
+
+.. rubric:: queue-work/main.c - lazy fibonacci
+.. literalinclude:: ../../code/queue-work/main.c
+    :language: c
+    :linenos:
+    :lines: 17-29
+
+The actual task function is simple, nothing to show that it is going to be
+run in a separate thread. The ``uv_work_t`` structure is the clue. You can pass
+arbitrary data through it using the ``void* data`` field and use it to
+communicate to and from the thread. But be sure you are using proper locks if
+you are changing things while both threads may be running.
+
+The trigger is ``uv_queue_work``:
+
+.. rubric:: queue-work/main.c
+.. literalinclude:: ../../code/queue-work/main.c
+    :language: c
+    :linenos:
+    :lines: 31-44
+    :emphasize-lines: 10
+
+The thread function will be launched in a separate thread, passed the
+``uv_work_t`` structure and once the function returns, the *after* function
+will be called on the thread the event loop is running in. It will be passed
+the same structure.
+
+For writing wrappers to blocking libraries, a common :ref:`pattern <baton>`
+is to use a baton to exchange data.
+
+Since libuv version `0.9.4` an additional function, ``uv_cancel()``, is
+available. This allows you to cancel tasks on the libuv work queue. Only tasks
+that *are yet to be started* can be cancelled. If a task has *already started
+executing, or it has finished executing*, ``uv_cancel()`` **will fail**.
+
+``uv_cancel()`` is useful to cleanup pending tasks if the user requests
+termination. For example, a music player may queue up multiple directories to
+be scanned for audio files. If the user terminates the program, it should quit
+quickly and not wait until all pending requests are run.
+
+Let's modify the fibonacci example to demonstrate ``uv_cancel()``. We first set
+up a signal handler for termination.
+
+.. rubric:: queue-cancel/main.c
+.. literalinclude:: ../../code/queue-cancel/main.c
+    :language: c
+    :linenos:
+    :lines: 43-
+
+When the user triggers the signal by pressing ``Ctrl+C`` we send
+``uv_cancel()`` to all the workers. ``uv_cancel()`` will return ``0`` for those that are already executing or finished.
+
+.. rubric:: queue-cancel/main.c
+.. literalinclude:: ../../code/queue-cancel/main.c
+    :language: c
+    :linenos:
+    :lines: 33-41
+    :emphasize-lines: 6
+
+For tasks that do get cancelled successfully, the *after* function is called
+with ``status`` set to ``UV_ECANCELED``.
+
+.. rubric:: queue-cancel/main.c
+.. literalinclude:: ../../code/queue-cancel/main.c
+    :language: c
+    :linenos:
+    :lines: 28-31
+    :emphasize-lines: 2
+
+``uv_cancel()`` can also be used with ``uv_fs_t`` and ``uv_getaddrinfo_t``
+requests. For the filesystem family of functions, ``uv_fs_t.errorno`` will be
+set to ``UV_ECANCELED``.
+
+.. TIP::
+
+    A well designed program would have a way to terminate long running workers
+    that have already started executing. Such a worker could periodically check
+    for a variable that only the main process sets to signal termination.
+
+.. _inter-thread-communication:
+
+Inter-thread communication
+--------------------------
+
+Sometimes you want various threads to actually send each other messages *while*
+they are running. For example you might be running some long duration task in
+a separate thread (perhaps using ``uv_queue_work``) but want to notify progress
+to the main thread. This is a simple example of having a download manager
+informing the user of the status of running downloads.
+
+.. rubric:: progress/main.c
+.. literalinclude:: ../../code/progress/main.c
+    :language: c
+    :linenos:
+    :lines: 7-8,35-
+    :emphasize-lines: 2,11
+
+The async thread communication works *on loops* so although any thread can be
+the message sender, only threads with libuv loops can be receivers (or rather
+the loop is the receiver). libuv will invoke the callback (``print_progress``)
+with the async watcher whenever it receives a message.
+
+.. warning::
+
+    It is important to realize that since the message send is *async*, the callback
+    may be invoked immediately after ``uv_async_send`` is called in another
+    thread, or it may be invoked after some time. libuv may also combine
+    multiple calls to ``uv_async_send`` and invoke your callback only once. The
+    only guarantee that libuv makes is -- The callback function is called *at
+    least once* after the call to ``uv_async_send``. If you have no pending
+    calls to ``uv_async_send``, the callback won't be called. If you make two
+    or more calls, and libuv hasn't had a chance to run the callback yet, it
+    *may* invoke your callback *only once* for the multiple invocations of
+    ``uv_async_send``. Your callback will never be called twice for just one
+    event.
+
+.. rubric:: progress/main.c
+.. literalinclude:: ../../code/progress/main.c
+    :language: c
+    :linenos:
+    :lines: 10-24
+    :emphasize-lines: 7-8
+
+In the download function, we modify the progress indicator and queue the message
+for delivery with ``uv_async_send``. Remember: ``uv_async_send`` is also
+non-blocking and will return immediately.
+
+.. rubric:: progress/main.c
+.. literalinclude:: ../../code/progress/main.c
+    :language: c
+    :linenos:
+    :lines: 31-34
+
+The callback is a standard libuv pattern, extracting the data from the watcher.
+
+Finally it is important to remember to clean up the watcher.
+
+.. rubric:: progress/main.c
+.. literalinclude:: ../../code/progress/main.c
+    :language: c
+    :linenos:
+    :lines: 26-29
+    :emphasize-lines: 3
+
+After this example, which showed the abuse of the ``data`` field, bnoordhuis_
+pointed out that using the ``data`` field is not thread safe, and
+``uv_async_send()`` is actually only meant to wake up the event loop. Use
+a mutex or rwlock to ensure accesses are performed in the right order.
+
+.. note::
+
+    mutexes and rwlocks **DO NOT** work inside a signal handler, whereas
+    ``uv_async_send`` does.
+
+One use case where ``uv_async_send`` is required is when interoperating with
+libraries that require thread affinity for their functionality. For example in
+node.js, a v8 engine instance, contexts and its objects are bound to the thread
+that the v8 instance was started in. Interacting with v8 data structures from
+another thread can lead to undefined results. Now consider some node.js module
+which binds a third party library. It may go something like this:
+
+1. In node, the third party library is set up with a JavaScript callback to be
+   invoked for more information::
+
+    var lib = require('lib');
+    lib.on_progress(function() {
+        console.log("Progress");
+    });
+
+    lib.do();
+
+    // do other stuff
+
+2. ``lib.do`` is supposed to be non-blocking but the third party lib is
+   blocking, so the binding uses ``uv_queue_work``.
+
+3. The actual work being done in a separate thread wants to invoke the progress
+   callback, but cannot directly call into v8 to interact with JavaScript. So
+   it uses ``uv_async_send``.
+
+4. The async callback, invoked in the main loop thread, which is the v8 thread,
+   then interacts with v8 to invoke the JavaScript callback.

+Utilities
+=========
+
+This chapter catalogues tools and techniques which are useful for common tasks.
+The `libev man page`_ already covers some patterns which can be adopted to
+libuv through simple API changes. It also covers parts of the libuv API that
+don't require entire chapters dedicated to them.
+
+Timers
+------
+
+Timers invoke the callback after a certain time has elapsed since the timer was
+started. libuv timers can also be set to invoke at regular intervals instead of
+just once.
+
+Simple use is to init a watcher and start it with a ``timeout``, and optional ``repeat``.
+Timers can be stopped at any time.
+
+.. code-block:: c
+
+    uv_timer_t timer_req;
+
+    uv_timer_init(loop, &timer_req);
+    uv_timer_start(&timer_req, callback, 5000, 2000);
+
+will start a repeating timer, which first starts 5 seconds (the ``timeout``) after the execution
+of ``uv_timer_start``, then repeats every 2 seconds (the ``repeat``). Use:
+
+.. code-block:: c
+
+    uv_timer_stop(&timer_req);
+
+to stop the timer. This can be used safely from within the callback as well.
+
+The repeat interval can be modified at any time with::
+
+    uv_timer_set_repeat(uv_timer_t *timer, int64_t repeat);
+
+which will take effect **when possible**. If this function is called from
+a timer callback, it means:
+
+* If the timer was non-repeating, the timer has already been stopped. Use
+  ``uv_timer_start`` again.
+* If the timer is repeating, the next timeout has already been scheduled, so
+  the old repeat interval will be used once more before the timer switches to
+  the new interval.
+
+The utility function::
+
+    int uv_timer_again(uv_timer_t *)
+
+applies **only to repeating timers** and is equivalent to stopping the timer
+and then starting it with both initial ``timeout`` and ``repeat`` set to the
+old ``repeat`` value. If the timer hasn't been started it fails (error code
+``UV_EINVAL``) and returns -1.
+
+An actual timer example is in the :ref:`reference count section
+<reference-count>`.
+
+.. _reference-count:
+
+Event loop reference count
+--------------------------
+
+The event loop only runs as long as there are active handles. This system
+works by having every handle increase the reference count of the event loop
+when it is started and decreasing the reference count when stopped. It is also
+possible to manually change the reference count of handles using::
+
+    void uv_ref(uv_handle_t*);
+    void uv_unref(uv_handle_t*);
+
+These functions can be used to allow a loop to exit even when a watcher is
+active or to use custom objects to keep the loop alive.
+
+The latter can be used with interval timers. You might have a garbage collector
+which runs every X seconds, or your network service might send a heartbeat to
+others periodically, but you don't want to have to stop them along all clean
+exit paths or error scenarios. Or you want the program to exit when all your
+other watchers are done. In that case just unref the timer immediately after
+creation so that if it is the only watcher running then ``uv_run`` will still
+exit.
+
+This is also used in node.js where some libuv methods are being bubbled up to
+the JS API. A ``uv_handle_t`` (the superclass of all watchers) is created per
+JS object and can be ref/unrefed.
+
+.. rubric:: ref-timer/main.c
+.. literalinclude:: ../../code/ref-timer/main.c
+    :language: c
+    :linenos:
+    :lines: 5-8, 17-
+    :emphasize-lines: 9
+
+We initialize the garbage collector timer, then immediately ``unref`` it.
+Observe how after 9 seconds, when the fake job is done, the program
+automatically exits, even though the garbage collector is still running.
+
+Idler pattern
+-------------
+
+The callbacks of idle handles are invoked once per event loop. The idle
+callback can be used to perform some very low priority activity. For example,
+you could dispatch a summary of the daily application performance to the
+developers for analysis during periods of idleness, or use the application's
+CPU time to perform SETI calculations :) An idle watcher is also useful in
+a GUI application. Say you are using an event loop for a file download. If the
+TCP socket is still being established and no other events are present your
+event loop will pause (**block**), which means your progress bar will freeze
+and the user will face an unresponsive application. In such a case queue up and
+idle watcher to keep the UI operational.
+
+.. rubric:: idle-compute/main.c

+    :language: c
+    :linenos:
+    :lines: 5-9, 34-
+    :emphasize-lines: 13
+
+Here we initialize the idle watcher and queue it up along with the actual
+events we are interested in. ``crunch_away`` will now be called repeatedly
+until the user types something and presses Return. Then it will be interrupted
+for a brief amount as the loop deals with the input data, after which it will
+keep calling the idle callback again.

+.. rubric:: idle-compute/main.c
+.. literalinclude:: ../../code/idle-compute/main.c
+    :language: c
+    :linenos:
+    :lines: 10-19
+
+.. _baton:
+
+Passing data to worker thread
+-----------------------------
+
+When using ``uv_queue_work`` you'll usually need to pass complex data through
+to the worker thread. The solution is to use a ``struct`` and set
+``uv_work_t.data`` to point to it. A slight variation is to have the
+``uv_work_t`` itself as the first member of this struct (called a baton [#]_).
+This allows cleaning up the work request and all the data in one free call.
+
+.. code-block:: c
+    :linenos:
+    :emphasize-lines: 2
+
+    struct ftp_baton {
+        uv_work_t req;
+        char *host;
+        int port;

+        char *password;

+    baton->req.data = (void*) baton;
+    baton->host = strdup("my.webhost.com");
+    baton->port = 21;
+    // ...
+
+    uv_queue_work(loop, &baton->req, ftp_session, ftp_cleanup);
+
+Here we create the baton and queue the task.
+
+Now the task function can extract the data it needs:
+
+.. code-block:: c
+    :linenos:
+    :emphasize-lines: 2, 12
+
+    void ftp_session(uv_work_t *req) {
+        ftp_baton *baton = (ftp_baton*) req->data;
+
+        fprintf(stderr, "Connecting to %s\n", baton->host);
+    }
+
+    void ftp_cleanup(uv_work_t *req) {
+        ftp_baton *baton = (ftp_baton*) req->data;
+
+        free(baton->host);
+        // ...
+        free(baton);
+    }
+
+We then free the baton which also frees the watcher.
+
+External I/O with polling
+-------------------------
+
+Usually third-party libraries will handle their own I/O, and keep track of
+their sockets and other files internally. In this case it isn't possible to use
+the standard stream I/O operations, but the library can still be integrated
+into the libuv event loop. All that is required is that the library allow you
+to access the underlying file descriptors and provide functions that process
+tasks in small increments as decided by your application. Some libraries though
+will not allow such access, providing only a standard blocking function which
+will perform the entire I/O transaction and only then return. It is unwise to
+use these in the event loop thread, use the :ref:`threadpool` instead. Of
+course, this will also mean losing granular control on the library.
+
+The ``uv_poll`` section of libuv simply watches file descriptors using the
+operating system notification mechanism. In some sense, all the I/O operations
+that libuv implements itself are also backed by ``uv_poll`` like code. Whenever
+the OS notices a change of state in file descriptors being polled, libuv will
+invoke the associated callback.
+
+Here we will walk through a simple download manager that will use libcurl_ to
+download files. Rather than give all control to libcurl, we'll instead be
+using the libuv event loop, and use the non-blocking, async multi_ interface to
+progress with the download whenever libuv notifies of I/O readiness.

+    :emphasize-lines: 7,21,24-25
+
+The way each library is integrated with libuv will vary. In the case of
+libcurl, we can register two callbacks. The socket callback ``handle_socket``
+is invoked whenever the state of a socket changes and we have to start polling
+it. ``start_timeout`` is called by libcurl to notify us of the next timeout
+interval, after which we should drive libcurl forward regardless of I/O status.
+This is so that libcurl can handle errors or do whatever else is required to
+get the download moving.
+
+Our downloader is to be invoked as::
+
+    $ ./uvwget [url1] [url2] ...
+
+So we add each argument as an URL

+    :language: c
+    :linenos:
+    :lines: 39-56
+    :emphasize-lines: 13-14
+
+We let libcurl directly write the data to a file, but much more is possible if
+you so desire.
+
+``start_timeout`` will be called immediately the first time by libcurl, so
+things are set in motion. This simply starts a libuv `timer <#timers>`_ which
+drives ``curl_multi_socket_action`` with ``CURL_SOCKET_TIMEOUT`` whenever it
+times out. ``curl_multi_socket_action`` is what drives libcurl, and what we
+call whenever sockets change state. But before we go into that, we need to poll
+on sockets whenever ``handle_socket`` is called.
+
+.. rubric:: uvwget/main.c - Setting up polling

+    :linenos:
+    :lines: 102-140
+    :emphasize-lines: 9,11,15,21,24
+
+We are interested in the socket fd ``s``, and the ``action``. For every socket
+we create a ``uv_poll_t`` handle if it doesn't exist, and associate it with the
+socket using ``curl_multi_assign``. This way ``socketp`` points to it whenever
+the callback is invoked.
+
+In the case that the download is done or fails, libcurl requests removal of the
+poll. So we stop and free the poll handle.
+
+Depending on what events libcurl wishes to watch for, we start polling with
+``UV_READABLE`` or ``UV_WRITABLE``. Now libuv will invoke the poll callback
+whenever the socket is ready for reading or writing. Calling ``uv_poll_start``
+multiple times on the same handle is acceptable, it will just update the events
+mask with the new value. ``curl_perform`` is the crux of this program.

+    :language: c
+    :linenos:
+    :lines: 81-95
+    :emphasize-lines: 2,6-7,12
+
+The first thing we do is to stop the timer, since there has been some progress
+in the interval. Then depending on what event triggered the callback, we set
+the correct flags. Then we call ``curl_multi_socket_action`` with the socket
+that progressed and the flags informing about what events happened. At this
+point libcurl does all of its internal tasks in small increments, and will
+attempt to return as fast as possible, which is exactly what an evented program
+wants in its main thread. libcurl keeps queueing messages into its own queue
+about transfer progress. In our case we are only interested in transfers that
+are completed. So we extract these messages, and clean up handles whose
+transfers are done.

+TODO
+
+Loading libraries
+-----------------
+
+libuv provides a cross platform API to dynamically load `shared libraries`_.
+This can be used to implement your own plugin/extension/module system and is
+used by node.js to implement ``require()`` support for bindings. The usage is
+quite simple as long as your library exports the right symbols. Be careful with
+sanity and security checks when loading third party code, otherwise your
+program will behave unpredictably. This example implements a very simple
+plugin system which does nothing except print the name of the plugin.
+
+Let us first look at the interface provided to plugin authors.
+
+.. rubric:: plugin/plugin.h
+.. literalinclude:: ../../code/plugin/plugin.h
+    :language: c
+    :linenos:
+
+You can similarly add more functions that plugin authors can use to do useful
+things in your application [#]_. A sample plugin using this API is:
+
+.. rubric:: plugin/hello.c
+.. literalinclude:: ../../code/plugin/hello.c
+    :language: c
+    :linenos:
+
+Our interface defines that all plugins should have an ``initialize`` function
+which will be called by the application. This plugin is compiled as a shared
+library and can be loaded by running our application::
+
+    $ ./plugin libhello.dylib
+    Loading libhello.dylib
+    Registered plugin "Hello World!"
+
+.. NOTE::
+
+    The shared library filename will be different depending on platforms. On
+    Linux it is ``libhello.so``.
+
+This is done by using ``uv_dlopen`` to first load the shared library
+``libhello.dylib``. Then we get access to the ``initialize`` function using
+``uv_dlsym`` and invoke it.
+
+.. rubric:: plugin/main.c
+.. literalinclude:: ../../code/plugin/main.c
+    :language: c
+    :linenos:
+    :lines: 7-
+    :emphasize-lines: 15, 18, 24
+
+``uv_dlopen`` expects a path to the shared library and sets the opaque
+``uv_lib_t`` pointer. It returns 0 on success, -1 on error. Use ``uv_dlerror``
+to get the error message.
+
+``uv_dlsym`` stores a pointer to the symbol in the second argument in the third
+argument. ``init_plugin_function`` is a function pointer to the sort of
+function we are looking for in the application's plugins.
+
+.. _shared libraries: https://en.wikipedia.org/wiki/Shared_library#Shared_libraries
+
+TTY
+---
+
+Text terminals have supported basic formatting for a long time, with a `pretty
+standardised`_ command set. This formatting is often used by programs to
+improve the readability of terminal output. For example ``grep --colour``.
+libuv provides the ``uv_tty_t`` abstraction (a stream) and related functions to
+implement the ANSI escape codes across all platforms. By this I mean that libuv
+converts ANSI codes to the Windows equivalent, and provides functions to get
+terminal information.
+
+.. _pretty standardised: https://en.wikipedia.org/wiki/ANSI_escape_sequences
+
+The first thing to do is to initialize a ``uv_tty_t`` with the file descriptor
+it reads/writes from. This is achieved with::
+
+    int uv_tty_init(uv_loop_t*, uv_tty_t*, uv_file fd, int unused)
+
+The ``unused`` parameter is now auto-detected and ignored. It previously needed
+to be set to use ``uv_read_start()`` on the stream.
+
+It is then best to use ``uv_tty_set_mode`` to set the mode to *normal*
+which enables most TTY formatting, flow-control and other settings. Other_ modes
+are also available.
+
+.. _Other: http://docs.libuv.org/en/v1.x/tty.html#c.uv_tty_mode_t
+
+Remember to call ``uv_tty_reset_mode`` when your program exits to restore the
+state of the terminal. Just good manners. Another set of good manners is to be
+aware of redirection. If the user redirects the output of your command to
+a file, control sequences should not be written as they impede readability and
+``grep``. To check if the file descriptor is indeed a TTY, call
+``uv_guess_handle`` with the file descriptor and compare the return value with
+``UV_TTY``.
+
+Here is a simple example which prints white text on a red background:
+
+.. rubric:: tty/main.c
+.. literalinclude:: ../../code/tty/main.c
+    :language: c
+    :linenos:
+    :emphasize-lines: 11-12,14,17,27
+
+The final TTY helper is ``uv_tty_get_winsize()`` which is used to get the
+width and height of the terminal and returns ``0`` on success. Here is a small
+program which does some animation using the function and character position
+escape codes.
+
+.. rubric:: tty-gravity/main.c
+.. literalinclude:: ../../code/tty-gravity/main.c
+    :language: c
+    :linenos:
+    :emphasize-lines: 19,25,38
+
+The escape codes are:
+
+======  =======================
+Code    Meaning
+======  =======================
+*2* J    Clear part of the screen, 2 is entire screen
+H        Moves cursor to certain position, default top-left
+*n* B    Moves cursor down by n lines
+*n* C    Moves cursor right by n columns
+m        Obeys string of display settings, in this case green background (40+2), white text (30+7)
+======  =======================
+
+As you can see this is very useful to produce nicely formatted output, or even
+console based arcade games if that tickles your fancy. For fancier control you
+can try `ncurses`_.
+
+.. _ncurses: https://www.gnu.org/software/ncurses/ncurses.html
+
+.. versionchanged:: 1.23.1: the `readable` parameter is now unused and ignored.
+                    The appropriate value will now be auto-detected from the kernel.

+
+:c:type:`uv_handle_t` --- Base handle
+=====================================
+
+`uv_handle_t` is the base type for all libuv handle types.
+
+Structures are aligned so that any libuv handle can be cast to `uv_handle_t`.
+All API functions defined here work with any handle type.
+
+Libuv handles are not movable. Pointers to handle structures passed to
+functions must remain valid for the duration of the requested operation. Take
+care when using stack allocated handles.
+
+Data types
+----------
+
+.. c:type:: uv_handle_t
+
+    The base libuv handle type.
+
+.. c:enum:: uv_handle_type
+

+
+    Union of all handle types.
+
+.. c:type:: void (*uv_alloc_cb)(uv_handle_t* handle, size_t suggested_size, uv_buf_t* buf)
+
+    Type definition for callback passed to :c:func:`uv_read_start` and
+    :c:func:`uv_udp_recv_start`. The user must allocate memory and fill the supplied
+    :c:type:`uv_buf_t` structure. If NULL is assigned as the buffer's base or 0 as its length,
+    a ``UV_ENOBUFS`` error will be triggered in the :c:type:`uv_udp_recv_cb` or the
+    :c:type:`uv_read_cb` callback.
+
+    Each buffer is used only once and the user is responsible for freeing it in the
+    :c:type:`uv_udp_recv_cb` or the :c:type:`uv_read_cb` callback.
+
+    A suggested size (65536 at the moment in most cases) is provided, but it's just an indication,
+    not related in any way to the pending data to be read. The user is free to allocate the amount
+    of memory they decide.
+
+    As an example, applications with custom allocation schemes such as using freelists, allocation
+    pools or slab based allocators may decide to use a different size which matches the memory
+    chunks they already have.
+
+    Example:
+
+    ::
+
+        static void my_alloc_cb(uv_handle_t* handle, size_t suggested_size, uv_buf_t* buf) {
+          buf->base = malloc(suggested_size);
+          buf->len = suggested_size;
+        }
+
+.. c:type:: void (*uv_close_cb)(uv_handle_t* handle)
+
+    Type definition for callback passed to :c:func:`uv_close`.
+
+
+Public members
+^^^^^^^^^^^^^^
+
+.. c:member:: uv_loop_t* uv_handle_t.loop
+
+    Pointer to the :c:type:`uv_loop_t` the handle is running on. Readonly.
+
+.. c:member:: uv_handle_type uv_handle_t.type
+
+    The :c:type:`uv_handle_type`, indicating the type of the underlying handle. Readonly.
+
+.. c:member:: void* uv_handle_t.data
+
+    Space for user-defined arbitrary data. libuv does not use this field.
+
+
+API
+---
+
+.. c:macro:: UV_HANDLE_TYPE_MAP(iter_macro)
+
+    Macro that expands to a series of invocations of `iter_macro` for
+    each of the handle types. `iter_macro` is invoked with two
+    arguments: the name of the `uv_handle_type` element without the
+    `UV_` prefix, and the name of the corresponding structure type
+    without the `uv_` prefix and `_t` suffix.
+
+.. c:function:: int uv_is_active(const uv_handle_t* handle)
+
+    Returns non-zero if the handle is active, zero if it's inactive. What
+    "active" means depends on the type of handle:
+
+    - A uv_async_t handle is always active and cannot be deactivated, except
+      by closing it with uv_close().
+
+    - A uv_pipe_t, uv_tcp_t, uv_udp_t, etc. handle - basically any handle that
+      deals with i/o - is active when it is doing something that involves i/o,
+      like reading, writing, connecting, accepting new connections, etc.
+
+    - A uv_check_t, uv_idle_t, uv_timer_t, etc. handle is active when it has
+      been started with a call to uv_check_start(), uv_idle_start(), etc.
+
+    Rule of thumb: if a handle of type `uv_foo_t` has a `uv_foo_start()`
+    function, then it's active from the moment that function is called.
+    Likewise, `uv_foo_stop()` deactivates the handle again.
+
+.. c:function:: int uv_is_closing(const uv_handle_t* handle)
+
+    Returns non-zero if the handle is closing or closed, zero otherwise.
+
+    .. note::
+        This function should only be used between the initialization of the handle and the
+        arrival of the close callback.
+
+.. c:function:: void uv_close(uv_handle_t* handle, uv_close_cb close_cb)
+
+    Request handle to be closed. `close_cb` will be called asynchronously after
+    this call. This MUST be called on each handle before memory is released.
+    Moreover, the memory can only be released in `close_cb` or after it has
+    returned.
+
+    Handles that wrap file descriptors are closed immediately but
+    `close_cb` will still be deferred to the next iteration of the event loop.
+    It gives you a chance to free up any resources associated with the handle.
+
+    In-progress requests, like uv_connect_t or uv_write_t, are cancelled and
+    have their callbacks called asynchronously with status=UV_ECANCELED.
+
+.. c:function:: void uv_ref(uv_handle_t* handle)
+
+    Reference the given handle. References are idempotent, that is, if a handle
+    is already referenced calling this function again will have no effect.
+
+    See :ref:`refcount`.
+
+.. c:function:: void uv_unref(uv_handle_t* handle)
+
+    Un-reference the given handle. References are idempotent, that is, if a handle
+    is not referenced calling this function again will have no effect.
+
+    See :ref:`refcount`.
+
+.. c:function:: int uv_has_ref(const uv_handle_t* handle)
+
+    Returns non-zero if the handle referenced, zero otherwise.
+
+    See :ref:`refcount`.
+
+.. c:function:: size_t uv_handle_size(uv_handle_type type)
+
+    Returns the size of the given handle type. Useful for FFI binding writers
+    who don't want to know the structure layout.
+
+
+Miscellaneous API functions
+---------------------------
+
+The following API functions take a :c:type:`uv_handle_t` argument but they work
+just for some handle types.
+
+.. c:function:: int uv_send_buffer_size(uv_handle_t* handle, int* value)
+
+    Gets or sets the size of the send buffer that the operating
+    system uses for the socket.
+
+    If `*value` == 0, then it will set `*value` to the current send buffer size.
+    If `*value` > 0 then it will use `*value` to set the new send buffer size.
+
+    On success, zero is returned. On error, a negative result is
+    returned.
+
+    This function works for TCP, pipe and UDP handles on Unix and for TCP and
+    UDP handles on Windows.
+
+    .. note::
+        Linux will set double the size and return double the size of the original set value.
+
+.. c:function:: int uv_recv_buffer_size(uv_handle_t* handle, int* value)
+
+    Gets or sets the size of the receive buffer that the operating
+    system uses for the socket.
+
+    If `*value` == 0, then it will set `*value` to the current receive buffer size.
+    If `*value` > 0 then it will use `*value` to set the new receive buffer size.
+
+    On success, zero is returned. On error, a negative result is
+    returned.
+
+    This function works for TCP, pipe and UDP handles on Unix and for TCP and
+    UDP handles on Windows.
+
+    .. note::
+        Linux will set double the size and return double the size of the original set value.
+
+.. c:function:: int uv_fileno(const uv_handle_t* handle, uv_os_fd_t* fd)
+
+    Gets the platform dependent file descriptor equivalent.
+
+    The following handles are supported: TCP, pipes, TTY, UDP and poll. Passing
+    any other handle type will fail with `UV_EINVAL`.
+
+    If a handle doesn't have an attached file descriptor yet or the handle
+    itself has been closed, this function will return `UV_EBADF`.
+
+    .. warning::
+        Be very careful when using this function. libuv assumes it's in control of the file
+        descriptor so any change to it may lead to malfunction.
+
+.. c:function:: uv_loop_t* uv_handle_get_loop(const uv_handle_t* handle)
+
+    Returns `handle->loop`.
+
+    .. versionadded:: 1.19.0
+
+.. c:function:: void* uv_handle_get_data(const uv_handle_t* handle)
+
+    Returns `handle->data`.
+
+    .. versionadded:: 1.19.0
+
+.. c:function:: void* uv_handle_set_data(uv_handle_t* handle, void* data)
+
+    Sets `handle->data` to `data`.
+
+    .. versionadded:: 1.19.0
+
+.. c:function:: uv_handle_type uv_handle_get_type(const uv_handle_t* handle)
+
+    Returns `handle->type`.
+
+    .. versionadded:: 1.19.0
+
+.. c:function:: const char* uv_handle_type_name(uv_handle_type type)
+
+    Returns the name for the equivalent struct for a given handle type,
+    e.g. `"pipe"` (as in :c:type:`uv_pipe_t`) for `UV_NAMED_PIPE`.
+
+    If no such handle type exists, this returns `NULL`.
+
+    .. versionadded:: 1.19.0
+
+.. _refcount:
+
+Reference counting
+------------------
+
+The libuv event loop (if run in the default mode) will run until there are no
+active `and` referenced handles left. The user can force the loop to exit early
+by unreferencing handles which are active, for example by calling :c:func:`uv_unref`
+after calling :c:func:`uv_timer_start`.
+
+A handle can be referenced or unreferenced, the refcounting scheme doesn't use
+a counter, so both operations are idempotent.
+
+All handles are referenced when active by default, see :c:func:`uv_is_active`
+for a more detailed explanation on what being `active` involves.

+.. _loop:
+
+:c:type:`uv_loop_t` --- Event loop
+==================================
+
+The event loop is the central part of libuv's functionality. It takes care
+of polling for i/o and scheduling callbacks to be run based on different sources
+of events.
+
+
+Data types
+----------
+
+.. c:type:: uv_loop_t
+
+    Loop data type.
+
+.. c:enum:: uv_run_mode
+
+    Mode used to run the loop with :c:func:`uv_run`.
+
+    ::
+
+        typedef enum {
+            UV_RUN_DEFAULT = 0,
+            UV_RUN_ONCE,
+            UV_RUN_NOWAIT
+        } uv_run_mode;
+
+.. c:type:: void (*uv_walk_cb)(uv_handle_t* handle, void* arg)
+
+    Type definition for callback passed to :c:func:`uv_walk`.
+
+
+Public members
+^^^^^^^^^^^^^^
+
+.. c:member:: void* uv_loop_t.data
+
+    Space for user-defined arbitrary data. libuv does not use and does not
+    touch this field.
+
+
+API
+---
+
+.. c:function:: int uv_loop_init(uv_loop_t* loop)
+
+    Initializes the given `uv_loop_t` structure.
+
+.. c:function:: int uv_loop_configure(uv_loop_t* loop, uv_loop_option option, ...)
+
+    .. versionadded:: 1.0.2
+
+    Set additional loop options.  You should normally call this before the
+    first call to :c:func:`uv_run` unless mentioned otherwise.
+
+    Returns 0 on success or a UV_E* error code on failure.  Be prepared to
+    handle UV_ENOSYS; it means the loop option is not supported by the platform.
+
+    Supported options:
+
+    - UV_LOOP_BLOCK_SIGNAL: Block a signal when polling for new events.  The
+      second argument to :c:func:`uv_loop_configure` is the signal number.
+
+      This operation is currently only implemented for SIGPROF signals,
+      to suppress unnecessary wakeups when using a sampling profiler.
+      Requesting other signals will fail with UV_EINVAL.
+
+    - UV_METRICS_IDLE_TIME: Accumulate the amount of idle time the event loop
+      spends in the event provider.
+
+      This option is necessary to use :c:func:`uv_metrics_idle_time`.
+
+    .. versionchanged:: 1.39.0 added the UV_METRICS_IDLE_TIME option.
+
+.. c:function:: int uv_loop_close(uv_loop_t* loop)
+
+    Releases all internal loop resources. Call this function only when the loop
+    has finished executing and all open handles and requests have been closed,
+    or it will return UV_EBUSY. After this function returns, the user can free
+    the memory allocated for the loop.
+
+.. c:function:: uv_loop_t* uv_default_loop(void)
+
+    Returns the initialized default loop. It may return NULL in case of
+    allocation failure.
+
+    This function is just a convenient way for having a global loop throughout
+    an application, the default loop is in no way different than the ones
+    initialized with :c:func:`uv_loop_init`. As such, the default loop can (and
+    should) be closed with :c:func:`uv_loop_close` so the resources associated
+    with it are freed.
+
+    .. warning::
+        This function is not thread safe.
+
+.. c:function:: int uv_run(uv_loop_t* loop, uv_run_mode mode)
+
+    This function runs the event loop. It will act differently depending on the
+    specified mode:
+
+    - UV_RUN_DEFAULT: Runs the event loop until there are no more active and
+      referenced handles or requests. Returns non-zero if :c:func:`uv_stop`
+      was called and there are still active handles or requests.  Returns
+      zero in all other cases.
+    - UV_RUN_ONCE: Poll for i/o once. Note that this function blocks if
+      there are no pending callbacks. Returns zero when done (no active handles
+      or requests left), or non-zero if more callbacks are expected (meaning
+      you should run the event loop again sometime in the future).
+    - UV_RUN_NOWAIT: Poll for i/o once but don't block if there are no
+      pending callbacks. Returns zero if done (no active handles
+      or requests left), or non-zero if more callbacks are expected (meaning
+      you should run the event loop again sometime in the future).
+
+    :c:func:`uv_run` is not reentrant. It must not be called from a callback.
+
+.. c:function:: int uv_loop_alive(const uv_loop_t* loop)
+
+    Returns non-zero if there are referenced active handles, active
+    requests or closing handles in the loop.
+
+.. c:function:: void uv_stop(uv_loop_t* loop)
+
+    Stop the event loop, causing :c:func:`uv_run` to end as soon as
+    possible. This will happen not sooner than the next loop iteration.
+    If this function was called before blocking for i/o, the loop won't block
+    for i/o on this iteration.
+
+.. c:function:: size_t uv_loop_size(void)
+
+    Returns the size of the `uv_loop_t` structure. Useful for FFI binding
+    writers who don't want to know the structure layout.
+
+.. c:function:: int uv_backend_fd(const uv_loop_t* loop)
+
+    Get backend file descriptor. Only kqueue, epoll and event ports are
+    supported.
+
+    This can be used in conjunction with `uv_run(loop, UV_RUN_NOWAIT)` to
+    poll in one thread and run the event loop's callbacks in another see
+    test/test-embed.c for an example.
+
+    .. note::
+        Embedding a kqueue fd in another kqueue pollset doesn't work on all platforms. It's not
+        an error to add the fd but it never generates events.
+
+.. c:function:: int uv_backend_timeout(const uv_loop_t* loop)
+
+    Get the poll timeout. The return value is in milliseconds, or -1 for no
+    timeout.
+
+.. c:function:: uint64_t uv_now(const uv_loop_t* loop)
+
+    Return the current timestamp in milliseconds. The timestamp is cached at
+    the start of the event loop tick, see :c:func:`uv_update_time` for details
+    and rationale.
+
+    The timestamp increases monotonically from some arbitrary point in time.
+    Don't make assumptions about the starting point, you will only get
+    disappointed.
+
+    .. note::
+        Use :c:func:`uv_hrtime` if you need sub-millisecond granularity.
+
+.. c:function:: void uv_update_time(uv_loop_t* loop)
+
+    Update the event loop's concept of "now". Libuv caches the current time
+    at the start of the event loop tick in order to reduce the number of
+    time-related system calls.
+
+    You won't normally need to call this function unless you have callbacks
+    that block the event loop for longer periods of time, where "longer" is
+    somewhat subjective but probably on the order of a millisecond or more.
+
+.. c:function:: void uv_walk(uv_loop_t* loop, uv_walk_cb walk_cb, void* arg)
+
+    Walk the list of handles: `walk_cb` will be executed with the given `arg`.
+
+.. c:function:: int uv_loop_fork(uv_loop_t* loop)
+
+    .. versionadded:: 1.12.0
+
+    Reinitialize any kernel state necessary in the child process after
+    a :man:`fork(2)` system call.
+
+    Previously started watchers will continue to be started in the
+    child process.
+
+    It is necessary to explicitly call this function on every event
+    loop created in the parent process that you plan to continue to
+    use in the child, including the default loop (even if you don't
+    continue to use it in the parent). This function must be called
+    before calling :c:func:`uv_run` or any other API function using
+    the loop in the child. Failure to do so will result in undefined
+    behaviour, possibly including duplicate events delivered to both
+    parent and child or aborting the child process.
+
+    When possible, it is preferred to create a new loop in the child
+    process instead of reusing a loop created in the parent. New loops
+    created in the child process after the fork should not use this
+    function.
+
+    This function is not implemented on Windows, where it returns ``UV_ENOSYS``.
+
+    .. caution::
+
+       This function is experimental. It may contain bugs, and is subject to
+       change or removal. API and ABI stability is not guaranteed.
+
+    .. note::
+
+        On Mac OS X, if directory FS event handles were in use in the
+        parent process *for any event loop*, the child process will no
+        longer be able to use the most efficient FSEvent
+        implementation. Instead, uses of directory FS event handles in
+        the child will fall back to the same implementation used for
+        files and on other kqueue-based systems.
+
+    .. caution::
+
+       On AIX and SunOS, FS event handles that were already started in
+       the parent process at the time of forking will *not* deliver
+       events in the child process; they must be closed and restarted.
+       On all other platforms, they will continue to work normally
+       without any further intervention.
+
+    .. caution::
+
+       Any previous value returned from :c:func:`uv_backend_fd` is now
+       invalid. That function must be called again to determine the
+       correct backend file descriptor.
+
+.. c:function:: void* uv_loop_get_data(const uv_loop_t* loop)
+
+    Returns `loop->data`.
+
+    .. versionadded:: 1.19.0
+
+.. c:function:: void* uv_loop_set_data(uv_loop_t* loop, void* data)
+
+    Sets `loop->data` to `data`.
+
+    .. versionadded:: 1.19.0

+
+libuv 0.10 -> 1.0.0 migration guide
+===================================
+
+Some APIs changed quite a bit throughout the 1.0.0 development process. Here
+is a migration guide for the most significant changes that happened after 0.10
+was released.
+
+
+Loop initialization and closing
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+In libuv 0.10 (and previous versions), loops were created with `uv_loop_new`, which
+allocated memory for a new loop and initialized it; and destroyed with `uv_loop_delete`,
+which destroyed the loop and freed the memory. Starting with 1.0, those are deprecated
+and the user is responsible for allocating the memory and then initializing the loop.
+
+libuv 0.10
+
+::
+
+    uv_loop_t* loop = uv_loop_new();
+    ...
+    uv_loop_delete(loop);
+
+libuv 1.0
+
+::
+
+    uv_loop_t* loop = malloc(sizeof *loop);
+    uv_loop_init(loop);
+    ...
+    uv_loop_close(loop);
+    free(loop);
+
+.. note::
+    Error handling was omitted for brevity. Check the documentation for :c:func:`uv_loop_init`
+    and :c:func:`uv_loop_close`.
+
+
+Error handling
+~~~~~~~~~~~~~~
+
+Error handling had a major overhaul in libuv 1.0. In general, functions and status parameters
+would get 0 for success and -1 for failure on libuv 0.10, and the user had to use `uv_last_error`
+to fetch the error code, which was a positive number.
+
+In 1.0, functions and status parameters contain the actual error code, which is 0 for success, or
+a negative number in case of error.
+
+libuv 0.10
+
+::
+
+    ... assume 'server' is a TCP server which is already listening
+    r = uv_listen((uv_stream_t*) server, 511, NULL);
+    if (r == -1) {
+      uv_err_t err = uv_last_error(uv_default_loop());
+      /* err.code contains UV_EADDRINUSE */
+    }
+
+libuv 1.0
+
+::
+
+    ... assume 'server' is a TCP server which is already listening
+    r = uv_listen((uv_stream_t*) server, 511, NULL);
+    if (r < 0) {
+      /* r contains UV_EADDRINUSE */
+    }
+
+
+Threadpool changes
+~~~~~~~~~~~~~~~~~~
+
+In libuv 0.10 Unix used a threadpool which defaulted to 4 threads, while Windows used the
+`QueueUserWorkItem` API, which uses a Windows internal threadpool, which defaults to 512
+threads per process.
+
+In 1.0, we unified both implementations, so Windows now uses the same implementation Unix
+does. The threadpool size can be set by exporting the ``UV_THREADPOOL_SIZE`` environment
+variable. See :c:ref:`threadpool`.
+
+
+Allocation callback API change
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+In libuv 0.10 the callback had to return a filled :c:type:`uv_buf_t` by value:
+
+::
+
+    uv_buf_t alloc_cb(uv_handle_t* handle, size_t size) {
+        return uv_buf_init(malloc(size), size);
+    }
+
+In libuv 1.0 a pointer to a buffer is passed to the callback, which the user
+needs to fill:
+
+::
+
+    void alloc_cb(uv_handle_t* handle, size_t size, uv_buf_t* buf) {
+        buf->base = malloc(size);
+        buf->len = size;
+    }
+
+
+Unification of IPv4 / IPv6 APIs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+libuv 1.0 unified the IPv4 and IPv6 APIS. There is no longer a `uv_tcp_bind` and `uv_tcp_bind6`
+duality, there is only :c:func:`uv_tcp_bind` now.
+
+IPv4 functions took ``struct sockaddr_in`` structures by value, and IPv6 functions took
+``struct sockaddr_in6``. Now functions take a ``struct sockaddr*`` (note it's a pointer).
+It can be stack allocated.
+
+libuv 0.10
+
+::
+
+    struct sockaddr_in addr = uv_ip4_addr("0.0.0.0", 1234);
+    ...
+    uv_tcp_bind(&server, addr)
+
+libuv 1.0
+
+::
+
+    struct sockaddr_in addr;
+    uv_ip4_addr("0.0.0.0", 1234, &addr)
+    ...
+    uv_tcp_bind(&server, (const struct sockaddr*) &addr, 0);
+
+The IPv4 and IPv6 struct creating functions (:c:func:`uv_ip4_addr` and :c:func:`uv_ip6_addr`)
+have also changed, make sure you check the documentation.
+
+..note::
+    This change applies to all functions that made a distinction between IPv4 and IPv6
+    addresses.
+
+
+Streams / UDP  data receive callback API change
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The streams and UDP data receive callbacks now get a pointer to a :c:type:`uv_buf_t` buffer,
+not a structure by value.
+
+libuv 0.10
+
+::
+
+    void on_read(uv_stream_t* handle,
+                 ssize_t nread,
+                 uv_buf_t buf) {
+        ...
+    }
+
+    void recv_cb(uv_udp_t* handle,
+                 ssize_t nread,
+                 uv_buf_t buf,
+                 struct sockaddr* addr,
+                 unsigned flags) {
+        ...
+    }
+
+libuv 1.0
+
+::
+
+    void on_read(uv_stream_t* handle,
+                 ssize_t nread,
+                 const uv_buf_t* buf) {
+        ...
+    }
+
+    void recv_cb(uv_udp_t* handle,
+                 ssize_t nread,
+                 const uv_buf_t* buf,
+                 const struct sockaddr* addr,
+                 unsigned flags) {
+        ...
+    }
+
+
+Receiving handles over pipes API change
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+In libuv 0.10 (and earlier versions) the `uv_read2_start` function was used to start reading
+data on a pipe, which could also result in the reception of handles over it. The callback
+for such function looked like this:
+
+::
+
+    void on_read(uv_pipe_t* pipe,
+                 ssize_t nread,
+                 uv_buf_t buf,
+                 uv_handle_type pending) {
+        ...
+    }
+
+In libuv 1.0, `uv_read2_start` was removed, and the user needs to check if there are pending
+handles using :c:func:`uv_pipe_pending_count` and :c:func:`uv_pipe_pending_type` while in
+the read callback:
+
+::
+
+    void on_read(uv_stream_t* handle,
+                 ssize_t nread,
+                 const uv_buf_t* buf) {
+        ...
+        while (uv_pipe_pending_count((uv_pipe_t*) handle) != 0) {
+            pending = uv_pipe_pending_type((uv_pipe_t*) handle);
+            ...
+        }
+        ...
+    }
+
+
+Extracting the file descriptor out of a handle
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+While it wasn't supported by the API, users often accessed the libuv internals in
+order to get access to the file descriptor of a TCP handle, for example.
+
+::
+
+    fd = handle->io_watcher.fd;
+
+This is now properly exposed through the :c:func:`uv_fileno` function.
+
+
+uv_fs_readdir rename and API change
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+`uv_fs_readdir` returned a list of strings in the `req->ptr` field upon completion in
+libuv 0.10. In 1.0, this function got renamed to :c:func:`uv_fs_scandir`, since it's
+actually implemented using ``scandir(3)``.
+
+In addition, instead of allocating a full list strings, the user is able to get one
+result at a time by using the :c:func:`uv_fs_scandir_next` function. This function
+does not need to make a roundtrip to the threadpool, because libuv will keep the
+list of *dents* returned by ``scandir(3)`` around.

+Miscellaneous utilities
+=======================
+
+This section contains miscellaneous functions that don't really belong in any
+other section.
+

+        } uv_timeval_t;
+
+.. c:type:: uv_timeval64_t

+            uint64_t ru_inblock; /* block input operations */
+            uint64_t ru_oublock; /* block output operations */
+            uint64_t ru_msgsnd; /* IPC messages sent (X) */
+            uint64_t ru_msgrcv; /* IPC messages received (X) */
+            uint64_t ru_nsignals; /* signals received (X) */
+            uint64_t ru_nvcsw; /* voluntary context switches (X) */
+            uint64_t ru_nivcsw; /* involuntary context switches (X) */
+        } uv_rusage_t;
+
+    Members marked with `(X)` are unsupported on Windows.
+    See :man:`getrusage(2)` for supported fields on Unix
+
+.. c:type:: uv_cpu_info_t
+
+    Data type for CPU information.
+
+    ::

+            } netmask;
+        } uv_interface_address_t;
+
+.. c:type:: uv_passwd_t
+
+    Data type for password file information.
+
+    ::
+
+        typedef struct uv_passwd_s {
+            char* username;
+            long uid;
+            long gid;
+            char* shell;
+            char* homedir;
+        } uv_passwd_t;
+
+.. c:type:: uv_utsname_t
+
+    Data type for operating system name and version information.
+
+    ::
+
+        typedef struct uv_utsname_s {
+            char sysname[256];
+            char release[256];
+            char version[256];
+            char machine[256];
+        } uv_utsname_t;
+
+.. c:type:: uv_env_item_t
+
+    Data type for environment variable storage.
+
+    ::
+
+        typedef struct uv_env_item_s {
+            char* name;
+            char* value;
+        } uv_env_item_t;
+
+.. c:type:: uv_random_t
+
+    Random data request type.
+
+API
+---
+
+.. c:function:: uv_handle_type uv_guess_handle(uv_file file)
+
+    Used to detect what type of stream should be used with a given file
+    descriptor. Usually this will be used during initialization to guess the
+    type of the stdio streams.
+
+    For :man:`isatty(3)` equivalent functionality use this function and test
+    for ``UV_TTY``.
+
+.. c:function:: int uv_replace_allocator(uv_malloc_func malloc_func, uv_realloc_func realloc_func, uv_calloc_func calloc_func, uv_free_func free_func)
+
+    .. versionadded:: 1.6.0
+
+    Override the use of the standard library's :man:`malloc(3)`,
+    :man:`calloc(3)`, :man:`realloc(3)`, :man:`free(3)`, memory allocation
+    functions.
+
+    This function must be called before any other libuv function is called or
+    after all resources have been freed and thus libuv doesn't reference
+    any allocated memory chunk.
+
+    On success, it returns 0, if any of the function pointers is NULL it
+    returns UV_EINVAL.
+
+    .. warning:: There is no protection against changing the allocator multiple
+                 times. If the user changes it they are responsible for making
+                 sure the allocator is changed while no memory was allocated with
+                 the previous allocator, or that they are compatible.
+
+    .. warning:: Allocator must be thread-safe.
+
+.. c:function:: void uv_library_shutdown(void);
+
+    .. versionadded:: 1.38.0
+
+    Release any global state that libuv is holding onto. Libuv will normally
+    do so automatically when it is unloaded but it can be instructed to perform
+    cleanup manually.
+
+    .. warning:: Only call :c:func:`uv_library_shutdown()` once.
+
+    .. warning:: Don't call :c:func:`uv_library_shutdown()` when there are
+                 still event loops or I/O requests active.
+
+    .. warning:: Don't call libuv functions after calling
+                 :c:func:`uv_library_shutdown()`.
+
+.. c:function:: uv_buf_t uv_buf_init(char* base, unsigned int len)
+
+    Constructor for :c:type:`uv_buf_t`.
+
+    Due to platform differences the user cannot rely on the ordering of the
+    `base` and `len` members of the uv_buf_t struct. The user is responsible for
+    freeing `base` after the uv_buf_t is done. Return struct passed by value.
+
+.. c:function:: char** uv_setup_args(int argc, char** argv)
+
+    Store the program arguments. Required for getting / setting the process title
+    or the executable path. Libuv may take ownership of the memory that `argv` 
+    points to. This function should be called exactly once, at program start-up.
+
+    Example:
+
+    ::
+
+        argv = uv_setup_args(argc, argv);  /* May return a copy of argv. */
+
+
+.. c:function:: int uv_get_process_title(char* buffer, size_t size)
+
+    Gets the title of the current process. You *must* call `uv_setup_args`
+    before calling this function on Unix and AIX systems. If `uv_setup_args`
+    has not been called on systems that require it, then `UV_ENOBUFS` is
+    returned. If `buffer` is `NULL` or `size` is zero, `UV_EINVAL` is returned.
+    If `size` cannot accommodate the process title and terminating `nul`
+    character, the function returns `UV_ENOBUFS`.
+
+    .. note::
+        On BSD systems, `uv_setup_args` is needed for getting the initial process
+        title. The process title returned will be an empty string until either
+        `uv_setup_args` or `uv_set_process_title` is called.
+
+    .. versionchanged:: 1.18.1 now thread-safe on all supported platforms.
+
+    .. versionchanged:: 1.39.0 now returns an error if `uv_setup_args` is needed
+                        but hasn't been called.
+
+.. c:function:: int uv_set_process_title(const char* title)
+
+    Sets the current process title. You *must* call `uv_setup_args` before
+    calling this function on Unix and AIX systems. If `uv_setup_args` has not
+    been called on systems that require it, then `UV_ENOBUFS` is returned. On
+    platforms with a fixed size buffer for the process title the contents of
+    `title` will be copied to the buffer and truncated if larger than the
+    available space. Other platforms will return `UV_ENOMEM` if they cannot
+    allocate enough space to duplicate the contents of `title`.
+
+    .. versionchanged:: 1.18.1 now thread-safe on all supported platforms.
+
+    .. versionchanged:: 1.39.0 now returns an error if `uv_setup_args` is needed
+                        but hasn't been called.
+
+.. c:function:: int uv_resident_set_memory(size_t* rss)
+
+    Gets the resident set size (RSS) for the current process.
+
+.. c:function:: int uv_uptime(double* uptime)
+
+    Gets the current system uptime. Depending on the system full or fractional seconds are returned.
+
+.. c:function:: int uv_getrusage(uv_rusage_t* rusage)
+
+    Gets the resource usage measures for the current process.
+
+    .. note::
+        On Windows not all fields are set, the unsupported fields are filled with zeroes.
+        See :c:type:`uv_rusage_t` for more details.
+
+.. c:function:: uv_pid_t uv_os_getpid(void)
+
+    Returns the current process ID.
+
+    .. versionadded:: 1.18.0
+
+.. c:function:: uv_pid_t uv_os_getppid(void)
+
+    Returns the parent process ID.
+
+    .. versionadded:: 1.16.0
+
+.. c:function:: unsigned int uv_available_parallelism(void)
+
+    Returns an estimate of the default amount of parallelism a program should
+    use. Always returns a non-zero value.
+
+    On Linux, inspects the calling thread's CPU affinity mask to determine if
+    it has been pinned to specific CPUs.
+
+    On Windows, the available parallelism may be underreported on systems with
+    more than 64 logical CPUs.
+
+    On other platforms, reports the number of CPUs that the operating system
+    considers to be online.
+
+    .. versionadded:: 1.44.0
+
+.. c:function:: int uv_cpu_info(uv_cpu_info_t** cpu_infos, int* count)
+
+    Gets information about the CPUs on the system. The `cpu_infos` array will
+    have `count` elements and needs to be freed with :c:func:`uv_free_cpu_info`.
+
+    Use :c:func:`uv_available_parallelism` if you need to know how many CPUs
+    are available for threads or child processes.
+
+.. c:function:: void uv_free_cpu_info(uv_cpu_info_t* cpu_infos, int count)
+
+    Frees the `cpu_infos` array previously allocated with :c:func:`uv_cpu_info`.
+
+.. c:function:: int uv_interface_addresses(uv_interface_address_t** addresses, int* count)
+
+    Gets address information about the network interfaces on the system. An
+    array of `count` elements is allocated and returned in `addresses`. It must
+    be freed by the user, calling :c:func:`uv_free_interface_addresses`.
+
+.. c:function:: void uv_free_interface_addresses(uv_interface_address_t* addresses, int count)
+
+    Free an array of :c:type:`uv_interface_address_t` which was returned by
+    :c:func:`uv_interface_addresses`.
+
+.. c:function:: void uv_loadavg(double avg[3])
+
+    Gets the load average. See: `<https://en.wikipedia.org/wiki/Load_(computing)>`_
+
+    .. note::
+        Returns [0,0,0] on Windows (i.e., it's not implemented).
+
+.. c:function:: int uv_ip4_addr(const char* ip, int port, struct sockaddr_in* addr)
+
+    Convert a string containing an IPv4 addresses to a binary structure.
+
+.. c:function:: int uv_ip6_addr(const char* ip, int port, struct sockaddr_in6* addr)
+
+    Convert a string containing an IPv6 addresses to a binary structure.
+
+.. c:function:: int uv_ip4_name(const struct sockaddr_in* src, char* dst, size_t size)
+
+    Convert a binary structure containing an IPv4 address to a string.
+
+.. c:function:: int uv_ip6_name(const struct sockaddr_in6* src, char* dst, size_t size)
+
+    Convert a binary structure containing an IPv6 address to a string.
+
+.. c:function:: int uv_ip_name(const struct sockaddr *src, char *dst, size_t size)
+
+    Convert a binary structure containing an IPv4 address or an IPv6 address to a string.
+
+.. c:function:: int uv_inet_ntop(int af, const void* src, char* dst, size_t size)
+.. c:function:: int uv_inet_pton(int af, const char* src, void* dst)
+
+    Cross-platform IPv6-capable implementation of :man:`inet_ntop(3)`
+    and :man:`inet_pton(3)`. On success they return 0. In case of error
+    the target `dst` pointer is unmodified.
+
+.. c:macro:: UV_IF_NAMESIZE
+
+    Maximum IPv6 interface identifier name length.  Defined as
+    `IFNAMSIZ` on Unix and `IF_NAMESIZE` on Linux and Windows.
+
+    .. versionadded:: 1.16.0
+
+.. c:function:: int uv_if_indextoname(unsigned int ifindex, char* buffer, size_t* size)
+
+    IPv6-capable implementation of :man:`if_indextoname(3)`. When called,
+    `*size` indicates the length of the `buffer`, which is used to store the
+    result.
+    On success, zero is returned, `buffer` contains the interface name, and
+    `*size` represents the string length of the `buffer`, excluding the NUL
+    terminator byte from `*size`. On error, a negative result is
+    returned. If `buffer` is not large enough to hold the result,
+    `UV_ENOBUFS` is returned, and `*size` represents the necessary size in
+    bytes, including the NUL terminator byte into the `*size`.
+
+    On Unix, the returned interface name can be used directly as an
+    interface identifier in scoped IPv6 addresses, e.g.
+    `fe80::abc:def1:2345%en0`.
+
+    On Windows, the returned interface cannot be used as an interface
+    identifier, as Windows uses numerical interface identifiers, e.g.
+    `fe80::abc:def1:2345%5`.
+
+    To get an interface identifier in a cross-platform compatible way,
+    use `uv_if_indextoiid()`.
+
+    Example:
+
+    ::
+
+        char ifname[UV_IF_NAMESIZE];
+        size_t size = sizeof(ifname);
+        uv_if_indextoname(sin6->sin6_scope_id, ifname, &size);
+
+    .. versionadded:: 1.16.0
+
+.. c:function:: int uv_if_indextoiid(unsigned int ifindex, char* buffer, size_t* size)
+
+    Retrieves a network interface identifier suitable for use in an IPv6 scoped
+    address. On Windows, returns the numeric `ifindex` as a string. On all other
+    platforms, `uv_if_indextoname()` is called. The result is written to
+    `buffer`, with `*size` indicating the length of `buffer`. If `buffer` is not
+    large enough to hold the result, then `UV_ENOBUFS` is returned, and `*size`
+    represents the size, including the NUL byte, required to hold the
+    result.
+
+    See `uv_if_indextoname` for further details.
+
+    .. versionadded:: 1.16.0
+
+.. c:function:: int uv_exepath(char* buffer, size_t* size)
+
+    Gets the executable path. You *must* call `uv_setup_args` before calling
+    this function.
+
+.. c:function:: int uv_cwd(char* buffer, size_t* size)
+
+    Gets the current working directory, and stores it in `buffer`. If the
+    current working directory is too large to fit in `buffer`, this function
+    returns `UV_ENOBUFS`, and sets `size` to the required length, including the
+    null terminator.
+
+    .. versionchanged:: 1.1.0
+
+        On Unix the path no longer ends in a slash.
+
+    .. versionchanged:: 1.9.0 the returned length includes the terminating null
+                        byte on `UV_ENOBUFS`, and the buffer is null terminated
+                        on success.
+
+
+.. c:function:: int uv_chdir(const char* dir)
+
+    Changes the current working directory.
+
+.. c:function:: int uv_os_homedir(char* buffer, size_t* size)
+
+    Gets the current user's home directory. On Windows, `uv_os_homedir()` first
+    checks the `USERPROFILE` environment variable using
+    `GetEnvironmentVariableW()`. If `USERPROFILE` is not set,
+    `GetUserProfileDirectoryW()` is called. On all other operating systems,
+    `uv_os_homedir()` first checks the `HOME` environment variable using
+    :man:`getenv(3)`. If `HOME` is not set, :man:`getpwuid_r(3)` is called. The
+    user's home directory is stored in `buffer`. When `uv_os_homedir()` is
+    called, `size` indicates the maximum size of `buffer`. On success `size` is set
+    to the string length of `buffer`. On `UV_ENOBUFS` failure `size` is set to the
+    required length for `buffer`, including the null byte.
+
+    .. warning::
+        `uv_os_homedir()` is not thread safe.
+
+    .. versionadded:: 1.6.0
+
+.. c:function:: int uv_os_tmpdir(char* buffer, size_t* size)
+
+    Gets the temp directory. On Windows, `uv_os_tmpdir()` uses `GetTempPathW()`.
+    On all other operating systems, `uv_os_tmpdir()` uses the first environment
+    variable found in the ordered list `TMPDIR`, `TMP`, `TEMP`, and `TEMPDIR`.
+    If none of these are found, the path `"/tmp"` is used, or, on Android,
+    `"/data/local/tmp"` is used. The temp directory is stored in `buffer`. When
+    `uv_os_tmpdir()` is called, `size` indicates the maximum size of `buffer`.
+    On success `size` is set to the string length of `buffer` (which does not
+    include the terminating null). On `UV_ENOBUFS` failure `size` is set to the
+    required length for `buffer`, including the null byte.
+
+    .. warning::
+        `uv_os_tmpdir()` is not thread safe.
+
+    .. versionadded:: 1.9.0
+
+.. c:function:: int uv_os_get_passwd(uv_passwd_t* pwd)
+
+    Gets a subset of the password file entry for the current effective uid (not
+    the real uid). The populated data includes the username, euid, gid, shell,
+    and home directory. On non-Windows systems, all data comes from
+    :man:`getpwuid_r(3)`. On Windows, uid and gid are set to -1 and have no
+    meaning, and shell is `NULL`. After successfully calling this function, the
+    memory allocated to `pwd` needs to be freed with
+    :c:func:`uv_os_free_passwd`.
+
+    .. versionadded:: 1.9.0
+
+.. c:function:: void uv_os_free_passwd(uv_passwd_t* pwd)
+
+    Frees the `pwd` memory previously allocated with :c:func:`uv_os_get_passwd`.
+
+    .. versionadded:: 1.9.0
+
+.. c:function:: uint64_t uv_get_free_memory(void)
+
+    Gets the amount of free memory available in the system, as reported by the kernel (in bytes).

+
+    Gets the total amount of physical memory in the system (in bytes).

+
+    Gets the amount of memory available to the process (in bytes) based on

+.. _poll:
+
+:c:type:`uv_poll_t` --- Poll handle
+===================================
+
+Poll handles are used to watch file descriptors for readability,
+writability and disconnection similar to the purpose of :man:`poll(2)`.
+
+The purpose of poll handles is to enable integrating external libraries that
+rely on the event loop to signal it about the socket status changes, like
+c-ares or libssh2. Using uv_poll_t for any other purpose is not recommended;
+:c:type:`uv_tcp_t`, :c:type:`uv_udp_t`, etc. provide an implementation that is faster and
+more scalable than what can be achieved with :c:type:`uv_poll_t`, especially on
+Windows.
+
+It is possible that poll handles occasionally signal that a file descriptor is
+readable or writable even when it isn't. The user should therefore always
+be prepared to handle EAGAIN or equivalent when it attempts to read from or
+write to the fd.
+
+It is not okay to have multiple active poll handles for the same socket, this
+can cause libuv to busyloop or otherwise malfunction.
+
+The user should not close a file descriptor while it is being polled by an
+active poll handle. This can cause the handle to report an error,
+but it might also start polling another socket. However the fd can be safely
+closed immediately after a call to :c:func:`uv_poll_stop` or :c:func:`uv_close`.
+
+.. note::
+    On windows only sockets can be polled with poll handles. On Unix any file
+    descriptor that would be accepted by :man:`poll(2)` can be used.
+
+.. note::
+    On AIX, watching for disconnection is not supported.
+
+Data types

+
+
+API
+---
+
+.. c:function:: int uv_poll_init(uv_loop_t* loop, uv_poll_t* handle, int fd)
+
+    Initialize the handle using a file descriptor.
+
+    .. versionchanged:: 1.2.2 the file descriptor is set to non-blocking mode.
+
+.. c:function:: int uv_poll_init_socket(uv_loop_t* loop, uv_poll_t* handle, uv_os_sock_t socket)
+
+    Initialize the handle using a socket descriptor. On Unix this is identical
+    to :c:func:`uv_poll_init`. On windows it takes a SOCKET handle.
+
+    .. versionchanged:: 1.2.2 the socket is set to non-blocking mode.
+
+.. c:function:: int uv_poll_start(uv_poll_t* handle, int events, uv_poll_cb cb)
+
+    Starts polling the file descriptor. `events` is a bitmask made up of
+    `UV_READABLE`, `UV_WRITABLE`, `UV_PRIORITIZED` and `UV_DISCONNECT`. As soon
+    as an event is detected the callback will be called with `status` set to 0,
+    and the detected events set on the `events` field.
+
+    The `UV_PRIORITIZED` event is used to watch for sysfs interrupts or TCP
+    out-of-band messages.
+
+    The `UV_DISCONNECT` event is optional in the sense that it may not be
+    reported and the user is free to ignore it, but it can help optimize the
+    shutdown path because an extra read or write call might be avoided.
+
+    If an error happens while polling, `status` will be < 0 and corresponds
+    with one of the `UV_E*` error codes (see :ref:`errors`). The user should
+    not close the socket while the handle is active. If the user does that
+    anyway, the callback *may* be called reporting an error status, but this is
+    **not** guaranteed.
+
+    .. note::
+        Calling :c:func:`uv_poll_start` on a handle that is already active is
+        fine. Doing so will update the events mask that is being watched for.
+
+    .. note::
+        Though `UV_DISCONNECT` can be set, it is unsupported on AIX and as such
+        will not be set on the `events` field in the callback.
+
+    .. note::
+        If one of the events `UV_READABLE` or `UV_WRITABLE` are set, the
+        callback will be called again, as long as the given fd/socket remains
+        readable or writable accordingly. Particularly in each of the following
+        scenarios:
+
+        * The callback has been called because the socket became
+          readable/writable and the callback did not conduct a read/write on
+          this socket at all.
+        * The callback committed a read on the socket, and has not read all the
+          available data (when `UV_READABLE` is set).
+        * The callback committed a write on the socket, but it remained
+          writable afterwards (when `UV_WRITABLE` is set).
+        * The socket has already became readable/writable before calling
+          :c:func:`uv_poll_start` on a poll handle associated with this socket,
+          and since then the state of the socket did not changed.
+
+        In all of the above listed scenarios, the socket remains readable or
+        writable and hence the callback will be called again (depending on the
+        events set in the bitmask). This behaviour is known as level
+        triggering.
+
+    .. versionchanged:: 1.9.0 Added the `UV_DISCONNECT` event.
+    .. versionchanged:: 1.14.0 Added the `UV_PRIORITIZED` event.
+
+.. c:function:: int uv_poll_stop(uv_poll_t* poll)
+
+    Stop polling the file descriptor, the callback will no longer be called.
+
+    .. note::
+        Calling :c:func:`uv_poll_stop` is effective immediately: any pending
+        callback is also canceled, even if the socket state change notification
+        was already pending.
+
+.. seealso:: The :c:type:`uv_handle_t` API functions also apply.

+    The :c:type:`uv_handle_t` members also apply.
+
+.. c:member:: uv_exit_cb uv_process_options_t.exit_cb

+
+    Path pointing to the program to be executed.
+
+.. c:member:: char** uv_process_options_t.args
+
+    Command line arguments. args[0] should be the path to the program. On
+    Windows this uses `CreateProcess` which concatenates the arguments into a
+    string this can cause some strange errors. See the
+    ``UV_PROCESS_WINDOWS_VERBATIM_ARGUMENTS`` flag on :c:type:`uv_process_flags`.
+
+.. c:member:: char** uv_process_options_t.env
+
+    Environment for the new process. If NULL the parents environment is used.
+
+.. c:member:: const char* uv_process_options_t.cwd
+
+    Current working directory for the subprocess.
+
+.. c:member:: unsigned int uv_process_options_t.flags
+

+
+.. c:member:: int uv_process_options_t.stdio_count
+.. c:member:: uv_stdio_container_t* uv_process_options_t.stdio
+
+    The `stdio` field points to an array of :c:type:`uv_stdio_container_t`
+    structs that describe the file descriptors that will be made available to
+    the child process. The convention is that stdio[0] points to stdin,
+    fd 1 is used for stdout, and fd 2 is stderr.
+
+    .. note::
+        On Windows file descriptors greater than 2 are available to the child process only if
+        the child processes uses the MSVCRT runtime.
+
+.. c:member:: uv_uid_t uv_process_options_t.uid
+.. c:member:: uv_gid_t uv_process_options_t.gid
+
+    Libuv can change the child process' user/group id. This happens only when
+    the appropriate bits are set in the flags fields.
+
+    .. note::
+        This is not supported on Windows, :c:func:`uv_spawn` will fail and set the error
+        to ``UV_ENOTSUP``.
+
+.. c:member:: uv_stdio_flags uv_stdio_container_t.flags
+
+    Flags specifying how the stdio container should be passed to the child.
+
+.. c:member:: union @0 uv_stdio_container_t.data
+
+    Union containing either the `stream` or `fd` to be passed on to the child
+    process.
+
+
+API
+---
+
+.. c:function:: void uv_disable_stdio_inheritance(void)
+
+    Disables inheritance for file descriptors / handles that this process
+    inherited from its parent. The effect is that child processes spawned by
+    this process don't accidentally inherit these handles.
+
+    It is recommended to call this function as early in your program as possible,
+    before the inherited file descriptors can be closed or duplicated.
+
+    .. note::
+        This function works on a best-effort basis: there is no guarantee that libuv can discover
+        all file descriptors that were inherited. In general it does a better job on Windows than
+        it does on Unix.
+
+.. c:function:: int uv_spawn(uv_loop_t* loop, uv_process_t* handle, const uv_process_options_t* options)
+
+    Initializes the process handle and starts the process. If the process is
+    successfully spawned, this function will return 0. Otherwise, the
+    negative error code corresponding to the reason it couldn't spawn is
+    returned.
+
+    Possible reasons for failing to spawn would include (but not be limited to)
+    the file to execute not existing, not having permissions to use the setuid or
+    setgid specified, or not having enough memory to allocate for the new
+    process.
+
+    .. versionchanged:: 1.24.0 Added `UV_PROCESS_WINDOWS_HIDE_CONSOLE` and
+                        `UV_PROCESS_WINDOWS_HIDE_GUI` flags.
+
+.. c:function:: int uv_process_kill(uv_process_t* handle, int signum)
+
+    Sends the specified signal to the given process handle. Check the documentation
+    on :c:ref:`signal` for signal support, specially on Windows.

+
+:c:type:`uv_signal_t` --- Signal handle
+=======================================
+
+Signal handles implement Unix style signal handling on a per-event loop bases.
+
+Windows notes
+-------------
+
+Reception of some signals is emulated:
+
+* SIGINT is normally delivered when the user presses CTRL+C. However, like
+  on Unix, it is not generated when terminal raw mode is enabled.
+
+* SIGBREAK is delivered when the user pressed CTRL + BREAK.
+
+* SIGHUP is generated when the user closes the console window. On SIGHUP the
+  program is given approximately 10 seconds to perform cleanup. After that
+  Windows will unconditionally terminate it.
+
+* SIGWINCH is raised whenever libuv detects that the console has been
+  resized. When a libuv app is running under a console emulator, or when a
+  32-bit libuv app is running on 64-bit system, SIGWINCH will be emulated. In
+  such cases SIGWINCH signals may not always be delivered in a timely manner.
+  For a writable :c:type:`uv_tty_t` handle libuv will only detect size changes
+  when the cursor is moved. When a readable :c:type:`uv_tty_t` handle is used,
+  resizing of the console buffer will be detected only if the handle is in raw
+  mode and is being read.
+
+* Watchers for other signals can be successfully created, but these signals
+  are never received. These signals are: `SIGILL`, `SIGABRT`, `SIGFPE`, `SIGSEGV`,
+  `SIGTERM` and `SIGKILL.`
+
+* Calls to raise() or abort() to programmatically raise a signal are
+  not detected by libuv; these will not trigger a signal watcher.
+
+.. versionchanged:: 1.15.0 SIGWINCH support on Windows was improved.
+.. versionchanged:: 1.31.0 32-bit libuv SIGWINCH support on 64-bit Windows was
+                           rolled back to old implementation.
+
+Unix notes
+----------
+
+* SIGKILL and SIGSTOP are impossible to catch.
+
+* Handling SIGBUS, SIGFPE, SIGILL or SIGSEGV via libuv results into undefined behavior.
+
+* SIGABRT will not be caught by libuv if generated by `abort()`, e.g. through `assert()`.
+
+* On Linux SIGRT0 and SIGRT1 (signals 32 and 33) are used by the NPTL pthreads library to
+  manage threads. Installing watchers for those signals will lead to unpredictable behavior
+  and is strongly discouraged. Future versions of libuv may simply reject them.

+
+:c:type:`uv_stream_t` --- Stream handle
+=======================================
+
+Stream handles provide an abstraction of a duplex communication channel.
+:c:type:`uv_stream_t` is an abstract type, libuv provides 3 stream implementations
+in the form of :c:type:`uv_tcp_t`, :c:type:`uv_pipe_t` and :c:type:`uv_tty_t`.
+
+
+Data types
+----------
+
+.. c:type:: uv_stream_t
+
+    Stream handle type.
+
+.. c:type:: uv_connect_t
+
+    Connect request type.
+
+.. c:type:: uv_shutdown_t
+
+    Shutdown request type.
+
+.. c:type:: uv_write_t
+
+    Write request type. Careful attention must be paid when reusing objects of
+    this type. When a stream is in non-blocking mode, write requests sent
+    with ``uv_write`` will be queued. Reusing objects at this point is undefined
+    behaviour. It is safe to reuse the ``uv_write_t`` object only after the
+    callback passed to ``uv_write`` is fired.
+
+.. c:type:: void (*uv_read_cb)(uv_stream_t* stream, ssize_t nread, const uv_buf_t* buf)
+
+    Callback called when data was read on a stream.
+
+    `nread` is > 0 if there is data available or < 0 on error. When we've
+    reached EOF, `nread` will be set to ``UV_EOF``. When `nread` < 0,
+    the `buf` parameter might not point to a valid buffer; in that case
+    `buf.len` and `buf.base` are both set to 0.
+
+    .. note::
+        `nread` might be 0, which does *not* indicate an error or EOF. This
+        is equivalent to ``EAGAIN`` or ``EWOULDBLOCK`` under ``read(2)``.
+
+    The callee is responsible for stopping/closing the stream when an error happens
+    by calling :c:func:`uv_read_stop` or :c:func:`uv_close`. Trying to read
+    from the stream again is undefined.
+
+    The callee is responsible for freeing the buffer, libuv does not reuse it.
+    The buffer may be a null buffer (where `buf->base` == NULL and `buf->len` == 0)
+    on error.
+
+.. c:type:: void (*uv_write_cb)(uv_write_t* req, int status)
+
+    Callback called after data was written on a stream. `status` will be 0 in
+    case of success, < 0 otherwise.
+
+.. c:type:: void (*uv_connect_cb)(uv_connect_t* req, int status)
+
+    Callback called after a connection started by :c:func:`uv_connect` is done.
+    `status` will be 0 in case of success, < 0 otherwise.
+
+.. c:type:: void (*uv_shutdown_cb)(uv_shutdown_t* req, int status)
+
+    Callback called after a shutdown request has been completed. `status` will
+    be 0 in case of success, < 0 otherwise.
+
+.. c:type:: void (*uv_connection_cb)(uv_stream_t* server, int status)
+
+    Callback called when a stream server has received an incoming connection.
+    The user can accept the connection by calling :c:func:`uv_accept`.
+    `status` will be 0 in case of success, < 0 otherwise.
+
+
+Public members
+^^^^^^^^^^^^^^
+
+.. c:member:: size_t uv_stream_t.write_queue_size
+
+    Contains the amount of queued bytes waiting to be sent. Readonly.
+
+.. c:member:: uv_stream_t* uv_connect_t.handle
+
+    Pointer to the stream where this connection request is running.
+
+.. c:member:: uv_stream_t* uv_shutdown_t.handle
+
+    Pointer to the stream where this shutdown request is running.
+
+.. c:member:: uv_stream_t* uv_write_t.handle
+
+    Pointer to the stream where this write request is running.
+
+.. c:member:: uv_stream_t* uv_write_t.send_handle
+
+    Pointer to the stream being sent using this write request.
+
+.. seealso:: The :c:type:`uv_handle_t` members also apply.
+
+
+API
+---
+
+.. c:function:: int uv_shutdown(uv_shutdown_t* req, uv_stream_t* handle, uv_shutdown_cb cb)
+
+    Shutdown the outgoing (write) side of a duplex stream. It waits for pending
+    write requests to complete. The `handle` should refer to a initialized stream.
+    `req` should be an uninitialized shutdown request struct. The `cb` is called
+    after shutdown is complete.
+
+.. c:function:: int uv_listen(uv_stream_t* stream, int backlog, uv_connection_cb cb)
+
+    Start listening for incoming connections. `backlog` indicates the number of
+    connections the kernel might queue, same as :man:`listen(2)`. When a new
+    incoming connection is received the :c:type:`uv_connection_cb` callback is
+    called.
+
+.. c:function:: int uv_accept(uv_stream_t* server, uv_stream_t* client)
+
+    This call is used in conjunction with :c:func:`uv_listen` to accept incoming
+    connections. Call this function after receiving a :c:type:`uv_connection_cb`
+    to accept the connection. Before calling this function the client handle must
+    be initialized. < 0 return value indicates an error.
+
+    When the :c:type:`uv_connection_cb` callback is called it is guaranteed that
+    this function will complete successfully the first time. If you attempt to use
+    it more than once, it may fail. It is suggested to only call this function once
+    per :c:type:`uv_connection_cb` call.
+
+    .. note::
+        `server` and `client` must be handles running on the same loop.
+
+.. c:function:: int uv_read_start(uv_stream_t* stream, uv_alloc_cb alloc_cb, uv_read_cb read_cb)
+
+    Read data from an incoming stream. The :c:type:`uv_read_cb` callback will
+    be made several times until there is no more data to read or
+    :c:func:`uv_read_stop` is called.
+
+    .. versionchanged:: 1.38.0 :c:func:`uv_read_start()` now consistently
+      returns `UV_EALREADY` when called twice, and `UV_EINVAL` when the
+      stream is closing. With older libuv versions, it returns `UV_EALREADY`
+      on Windows but not UNIX, and `UV_EINVAL` on UNIX but not Windows.
+
+.. c:function:: int uv_read_stop(uv_stream_t*)
+
+    Stop reading data from the stream. The :c:type:`uv_read_cb` callback will
+    no longer be called.
+
+    This function is idempotent and may be safely called on a stopped stream.
+
+    This function will always succeed; hence, checking its return value is
+    unnecessary. A non-zero return indicates that finishing releasing resources
+    may be pending on the next input event on that TTY on Windows, and does not
+    indicate failure.
+
+.. c:function:: int uv_write(uv_write_t* req, uv_stream_t* handle, const uv_buf_t bufs[], unsigned int nbufs, uv_write_cb cb)
+
+    Write data to stream. Buffers are written in order. Example:
+
+    ::
+
+        void cb(uv_write_t* req, int status) {
+            /* Logic which handles the write result */
+        }
+
+        uv_buf_t a[] = {
+            { .base = "1", .len = 1 },
+            { .base = "2", .len = 1 }
+        };
+
+        uv_buf_t b[] = {
+            { .base = "3", .len = 1 },
+            { .base = "4", .len = 1 }
+        };
+
+        uv_write_t req1;
+        uv_write_t req2;
+
+        /* writes "1234" */
+        uv_write(&req1, stream, a, 2, cb);
+        uv_write(&req2, stream, b, 2, cb);
+
+    .. note::
+        The memory pointed to by the buffers must remain valid until the callback gets called.
+        This also holds for :c:func:`uv_write2`.
+
+.. c:function:: int uv_write2(uv_write_t* req, uv_stream_t* handle, const uv_buf_t bufs[], unsigned int nbufs, uv_stream_t* send_handle, uv_write_cb cb)
+
+    Extended write function for sending handles over a pipe. The pipe must be
+    initialized with `ipc` == 1.
+
+    .. note::
+        `send_handle` must be a TCP, pipe and UDP handle on Unix, or a TCP
+        handle on Windows, which is a server or a connection (listening or
+        connected state). Bound sockets or pipes will be assumed to be servers.
+
+.. c:function:: int uv_try_write(uv_stream_t* handle, const uv_buf_t bufs[], unsigned int nbufs)
+
+    Same as :c:func:`uv_write`, but won't queue a write request if it can't be
+    completed immediately.
+
+    Will return either:
+
+    * > 0: number of bytes written (can be less than the supplied buffer size).
+    * < 0: negative error code (``UV_EAGAIN`` is returned if no data can be sent
+      immediately).
+
+.. c:function:: int uv_try_write2(uv_stream_t* handle, const uv_buf_t bufs[], unsigned int nbufs, uv_stream_t* send_handle)
+
+    Same as :c:func:`uv_try_write` and extended write function for sending
+    handles over a pipe like c:func:`uv_write2`.
+
+    Try to send a handle is not supported on Windows,
+    where it returns ``UV_EAGAIN``.
+
+    .. versionadded:: 1.42.0
+    
+.. c:function:: int uv_is_readable(const uv_stream_t* handle)
+
+    Returns 1 if the stream is readable, 0 otherwise.
+
+.. c:function:: int uv_is_writable(const uv_stream_t* handle)
+
+    Returns 1 if the stream is writable, 0 otherwise.
+
+.. c:function:: int uv_stream_set_blocking(uv_stream_t* handle, int blocking)
+
+    Enable or disable blocking mode for a stream.
+
+    When blocking mode is enabled all writes complete synchronously. The
+    interface remains unchanged otherwise, e.g. completion or failure of the
+    operation will still be reported through a callback which is made
+    asynchronously.
+
+    .. warning::
+        Relying too much on this API is not recommended. It is likely to change
+        significantly in the future.
+
+        Currently only works on Windows for :c:type:`uv_pipe_t` handles.
+        On UNIX platforms, all :c:type:`uv_stream_t` handles are supported.
+
+        Also libuv currently makes no ordering guarantee when the blocking mode
+        is changed after write requests have already been submitted. Therefore it is
+        recommended to set the blocking mode immediately after opening or creating
+        the stream.
+
+    .. versionchanged:: 1.4.0 UNIX implementation added.
+
+.. c:function:: size_t uv_stream_get_write_queue_size(const uv_stream_t* stream)
+
+    Returns `stream->write_queue_size`.
+
+    .. versionadded:: 1.19.0
+
+.. seealso:: The :c:type:`uv_handle_t` API functions also apply.

+
+:c:type:`uv_tcp_t` --- TCP handle
+=================================
+
+TCP handles are used to represent both TCP streams and servers.
+
+:c:type:`uv_tcp_t` is a 'subclass' of :c:type:`uv_stream_t`.
+
+
+Data types
+----------
+
+.. c:type:: uv_tcp_t
+
+    TCP handle type.
+
+
+Public members
+^^^^^^^^^^^^^^
+
+N/A
+
+.. seealso:: The :c:type:`uv_stream_t` members also apply.
+
+
+API
+---
+
+.. c:function:: int uv_tcp_init(uv_loop_t* loop, uv_tcp_t* handle)
+
+    Initialize the handle. No socket is created as of yet.
+
+.. c:function:: int uv_tcp_init_ex(uv_loop_t* loop, uv_tcp_t* handle, unsigned int flags)
+
+    Initialize the handle with the specified flags. At the moment only the lower 8 bits
+    of the `flags` parameter are used as the socket domain. A socket will be created
+    for the given domain. If the specified domain is ``AF_UNSPEC`` no socket is created,
+    just like :c:func:`uv_tcp_init`.
+
+    .. versionadded:: 1.7.0
+
+.. c:function:: int uv_tcp_open(uv_tcp_t* handle, uv_os_sock_t sock)
+
+    Open an existing file descriptor or SOCKET as a TCP handle.
+
+    .. versionchanged:: 1.2.1 the file descriptor is set to non-blocking mode.
+
+    .. note::
+        The passed file descriptor or SOCKET is not checked for its type, but
+        it's required that it represents a valid stream socket.
+
+.. c:function:: int uv_tcp_nodelay(uv_tcp_t* handle, int enable)
+
+    Enable `TCP_NODELAY`, which disables Nagle's algorithm.
+
+.. c:function:: int uv_tcp_keepalive(uv_tcp_t* handle, int enable, unsigned int delay)
+
+    Enable / disable TCP keep-alive. `delay` is the initial delay in seconds,
+    ignored when `enable` is zero.
+
+    After `delay` has been reached, 10 successive probes, each spaced 1 second
+    from the previous one, will still happen. If the connection is still lost
+    at the end of this procedure, then the handle is destroyed with a
+    ``UV_ETIMEDOUT`` error passed to the corresponding callback.
+
+.. c:function:: int uv_tcp_simultaneous_accepts(uv_tcp_t* handle, int enable)
+
+    Enable / disable simultaneous asynchronous accept requests that are
+    queued by the operating system when listening for new TCP connections.
+
+    This setting is used to tune a TCP server for the desired performance.
+    Having simultaneous accepts can significantly improve the rate of accepting
+    connections (which is why it is enabled by default) but may lead to uneven
+    load distribution in multi-process setups.
+
+.. c:function:: int uv_tcp_bind(uv_tcp_t* handle, const struct sockaddr* addr, unsigned int flags)
+
+    Bind the handle to an address and port. `addr` should point to an
+    initialized ``struct sockaddr_in`` or ``struct sockaddr_in6``.
+
+    When the port is already taken, you can expect to see an ``UV_EADDRINUSE``
+    error from :c:func:`uv_listen` or :c:func:`uv_tcp_connect`. That is,
+    a successful call to this function does not guarantee that the call
+    to :c:func:`uv_listen` or :c:func:`uv_tcp_connect` will succeed as well.
+
+    `flags` can contain ``UV_TCP_IPV6ONLY``, in which case dual-stack support
+    is disabled and only IPv6 is used.
+
+.. c:function:: int uv_tcp_getsockname(const uv_tcp_t* handle, struct sockaddr* name, int* namelen)
+
+    Get the current address to which the handle is bound. `name` must point to
+    a valid and big enough chunk of memory, ``struct sockaddr_storage`` is
+    recommended for IPv4 and IPv6 support.
+
+.. c:function:: int uv_tcp_getpeername(const uv_tcp_t* handle, struct sockaddr* name, int* namelen)
+
+    Get the address of the peer connected to the handle. `name` must point to
+    a valid and big enough chunk of memory, ``struct sockaddr_storage`` is
+    recommended for IPv4 and IPv6 support.
+
+.. c:function:: int uv_tcp_connect(uv_connect_t* req, uv_tcp_t* handle, const struct sockaddr* addr, uv_connect_cb cb)
+
+    Establish an IPv4 or IPv6 TCP connection. Provide an initialized TCP handle
+    and an uninitialized :c:type:`uv_connect_t`. `addr` should point to an
+    initialized ``struct sockaddr_in`` or ``struct sockaddr_in6``.
+
+    On Windows if the `addr` is initialized to point to an unspecified address
+    (``0.0.0.0`` or ``::``) it will be changed to point to ``localhost``.
+    This is done to match the behavior of Linux systems.
+
+    The callback is made when the connection has been established or when a
+    connection error happened.
+
+    .. versionchanged:: 1.19.0 added ``0.0.0.0`` and ``::`` to ``localhost``
+        mapping
+
+.. seealso:: The :c:type:`uv_stream_t` API functions also apply.
+
+.. c:function:: int uv_tcp_close_reset(uv_tcp_t* handle, uv_close_cb close_cb)
+
+    Resets a TCP connection by sending a RST packet. This is accomplished by
+    setting the `SO_LINGER` socket option with a linger interval of zero and
+    then calling :c:func:`uv_close`.
+    Due to some platform inconsistencies, mixing of :c:func:`uv_shutdown` and
+    :c:func:`uv_tcp_close_reset` calls is not allowed.
+
+    .. versionadded:: 1.32.0
+
+.. c:function:: int uv_socketpair(int type, int protocol, uv_os_sock_t socket_vector[2], int flags0, int flags1)
+
+    Create a pair of connected sockets with the specified properties.
+    The resulting handles can be passed to `uv_tcp_open`, used with `uv_spawn`,
+    or for any other purpose.
+
+    Valid values for `flags0` and `flags1` are:
+
+      - UV_NONBLOCK_PIPE: Opens the specified socket handle for `OVERLAPPED`
+        or `FIONBIO`/`O_NONBLOCK` I/O usage.
+        This is recommended for handles that will be used by libuv,
+        and not usually recommended otherwise.
+
+    Equivalent to :man:`socketpair(2)` with a domain of AF_UNIX.

+Threading and synchronization utilities
+=======================================
+
+libuv provides cross-platform implementations for multiple threading and
+synchronization primitives. The API largely follows the pthreads API.
+
+
+Data types
+----------
+
+.. c:type:: uv_thread_t
+
+    Thread data type.
+
+.. c:type:: void (*uv_thread_cb)(void* arg)
+
+    Callback that is invoked to initialize thread execution. `arg` is the same
+    value that was passed to :c:func:`uv_thread_create`.
+
+.. c:type:: uv_key_t
+
+    Thread-local key data type.
+
+.. c:type:: uv_once_t
+
+    Once-only initializer data type.
+
+.. c:type:: uv_mutex_t
+
+    Mutex data type.
+
+.. c:type:: uv_rwlock_t
+
+    Read-write lock data type.
+
+.. c:type:: uv_sem_t
+
+    Semaphore data type.
+
+.. c:type:: uv_cond_t
+
+    Condition data type.
+
+.. c:type:: uv_barrier_t
+
+    Barrier data type.
+
+
+API
+---
+
+Threads
+^^^^^^^
+
+.. c:type:: uv_thread_options_t
+
+    Options for spawning a new thread (passed to :c:func:`uv_thread_create_ex`).
+
+    ::
+
+        typedef struct uv_thread_options_s {
+          enum {
+            UV_THREAD_NO_FLAGS = 0x00,
+            UV_THREAD_HAS_STACK_SIZE = 0x01
+          } flags;
+          size_t stack_size;
+        } uv_thread_options_t;
+
+    More fields may be added to this struct at any time, so its exact
+    layout and size should not be relied upon.
+
+    .. versionadded:: 1.26.0
+
+.. c:function:: int uv_thread_create(uv_thread_t* tid, uv_thread_cb entry, void* arg)
+
+    .. versionchanged:: 1.4.1 returns a UV_E* error code on failure
+
+.. c:function:: int uv_thread_create_ex(uv_thread_t* tid, const uv_thread_options_t* params, uv_thread_cb entry, void* arg)
+
+    Like :c:func:`uv_thread_create`, but additionally specifies options for creating a new thread.
+
+    If `UV_THREAD_HAS_STACK_SIZE` is set, `stack_size` specifies a stack size for the new thread.
+    `0` indicates that the default value should be used, i.e. behaves as if the flag was not set.
+    Other values will be rounded up to the nearest page boundary.
+
+    .. versionadded:: 1.26.0
+
+.. c:function:: uv_thread_t uv_thread_self(void)
+.. c:function:: int uv_thread_join(uv_thread_t *tid)
+.. c:function:: int uv_thread_equal(const uv_thread_t* t1, const uv_thread_t* t2)
+
+Thread-local storage
+^^^^^^^^^^^^^^^^^^^^
+
+.. note::
+    The total thread-local storage size may be limited. That is, it may not be possible to
+    create many TLS keys.
+
+.. c:function:: int uv_key_create(uv_key_t* key)
+.. c:function:: void uv_key_delete(uv_key_t* key)
+.. c:function:: void* uv_key_get(uv_key_t* key)
+.. c:function:: void uv_key_set(uv_key_t* key, void* value)
+
+Once-only initialization
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+Runs a function once and only once. Concurrent calls to :c:func:`uv_once` with the
+same guard will block all callers except one (it's unspecified which one).
+The guard should be initialized statically with the UV_ONCE_INIT macro.
+
+.. c:function:: void uv_once(uv_once_t* guard, void (*callback)(void))
+
+Mutex locks
+^^^^^^^^^^^
+
+Functions return 0 on success or an error code < 0 (unless the
+return type is void, of course).
+
+.. c:function:: int uv_mutex_init(uv_mutex_t* handle)
+.. c:function:: int uv_mutex_init_recursive(uv_mutex_t* handle)
+.. c:function:: void uv_mutex_destroy(uv_mutex_t* handle)

+.. c:function:: int uv_mutex_trylock(uv_mutex_t* handle)
+.. c:function:: void uv_mutex_unlock(uv_mutex_t* handle)
+
+Read-write locks
+^^^^^^^^^^^^^^^^
+
+Functions return 0 on success or an error code < 0 (unless the
+return type is void, of course).
+
+.. c:function:: int uv_rwlock_init(uv_rwlock_t* rwlock)
+.. c:function:: void uv_rwlock_destroy(uv_rwlock_t* rwlock)
+.. c:function:: void uv_rwlock_rdlock(uv_rwlock_t* rwlock)

+.. c:function:: void uv_rwlock_wrunlock(uv_rwlock_t* rwlock)
+
+Semaphores
+^^^^^^^^^^
+
+Functions return 0 on success or an error code < 0 (unless the
+return type is void, of course).
+
+.. c:function:: int uv_sem_init(uv_sem_t* sem, unsigned int value)
+.. c:function:: void uv_sem_destroy(uv_sem_t* sem)
+.. c:function:: void uv_sem_post(uv_sem_t* sem)
+.. c:function:: void uv_sem_wait(uv_sem_t* sem)
+.. c:function:: int uv_sem_trywait(uv_sem_t* sem)
+
+Conditions
+^^^^^^^^^^
+
+Functions return 0 on success or an error code < 0 (unless the
+return type is void, of course).
+
+.. note::
+    1. Callers should be prepared to deal with spurious wakeups on :c:func:`uv_cond_wait`
+       and :c:func:`uv_cond_timedwait`.
+    2. The timeout parameter for :c:func:`uv_cond_timedwait` is relative to the time
+       at which function is called.
+    3. On z/OS, the timeout parameter for :c:func:`uv_cond_timedwait` is converted to an
+       absolute system time at which the wait expires. If the current system clock time
+       passes the absolute time calculated before the condition is signaled, an ETIMEDOUT
+       error results. After the wait begins, the wait time is not affected by changes
+       to the system clock.
+
+.. c:function:: int uv_cond_init(uv_cond_t* cond)
+.. c:function:: void uv_cond_destroy(uv_cond_t* cond)

+
+Barriers
+^^^^^^^^
+
+Functions return 0 on success or an error code < 0 (unless the
+return type is void, of course).
+
+.. note::
+    :c:func:`uv_barrier_wait` returns a value > 0 to an arbitrarily chosen "serializer" thread
+    to facilitate cleanup, i.e.
+
+    ::
+
+        if (uv_barrier_wait(&barrier) > 0)

+
+Thread pool work scheduling
+===========================
+
+libuv provides a threadpool which can be used to run user code and get notified
+in the loop thread. This thread pool is internally used to run all file system
+operations, as well as getaddrinfo and getnameinfo requests.
+
+Its default size is 4, but it can be changed at startup time by setting the
+``UV_THREADPOOL_SIZE`` environment variable to any value (the absolute maximum
+is 1024).
+
+.. versionchanged:: 1.30.0 the maximum UV_THREADPOOL_SIZE allowed was increased from 128 to 1024.
+
+The threadpool is global and shared across all event loops. When a particular
+function makes use of the threadpool (i.e. when using :c:func:`uv_queue_work`)
+libuv preallocates and initializes the maximum number of threads allowed by
+``UV_THREADPOOL_SIZE``. This causes a relatively minor memory overhead
+(~1MB for 128 threads) but increases the performance of threading at runtime.
+
+.. note::
+    Note that even though a global thread pool which is shared across all events
+    loops is used, the functions are not thread safe.
+
+
+Data types
+----------
+
+.. c:type:: uv_work_t
+
+    Work request type.
+
+.. c:type:: void (*uv_work_cb)(uv_work_t* req)
+
+    Callback passed to :c:func:`uv_queue_work` which will be run on the thread
+    pool.
+
+.. c:type:: void (*uv_after_work_cb)(uv_work_t* req, int status)
+
+    Callback passed to :c:func:`uv_queue_work` which will be called on the loop
+    thread after the work on the threadpool has been completed. If the work
+    was cancelled using :c:func:`uv_cancel` `status` will be ``UV_ECANCELED``.
+
+

+    from the threadpool. Once `work_cb` is completed, `after_work_cb` will be

+
+.. c:function:: int uv_timer_start(uv_timer_t* handle, uv_timer_cb cb, uint64_t timeout, uint64_t repeat)
+
+    Start the timer. `timeout` and `repeat` are in milliseconds.
+
+    If `timeout` is zero, the callback fires on the next event loop iteration.
+    If `repeat` is non-zero, the callback fires first after `timeout`
+    milliseconds and then repeatedly after `repeat` milliseconds.

+
+.. c:function:: void uv_timer_set_repeat(uv_timer_t* handle, uint64_t repeat)

+
+    For example, if a 50ms repeating timer first runs for 17ms, it will be
+    scheduled to run again 33ms later. If other tasks consume more than the
+    33ms following the first timer callback, then the callback will run as soon

+
+    .. note::
+        If the repeat value is set from a timer callback it does not immediately take effect.

+
+    * `handle`: UDP handle
+    * `nread`:  Number of bytes that have been received.
+      0 if there is no more data to read. Note that 0 may also mean that an
+      empty datagram was received (in this case `addr` is not NULL). < 0 if
+      a transmission error was detected; if using :man:`recvmmsg(2)` no more
+      chunks will be received and the buffer can be freed safely.
+    * `buf`: :c:type:`uv_buf_t` with the received data.
+    * `addr`: ``struct sockaddr*`` containing the address of the sender.
+      Can be NULL. Valid for the duration of the callback only.
+    * `flags`: One or more or'ed UV_UDP_* constants.
+
+    The callee is responsible for freeing the buffer, libuv does not reuse it.

+    allocated data with the `UV_UDP_MMSG_CHUNK` flag cleared and the `UV_UDP_MMSG_FREE`
+    flag set. If a UDP socket error occurs, `nread` will be < 0. In either scenario,

+Public members
+^^^^^^^^^^^^^^
+
+.. c:member:: size_t uv_udp_t.send_queue_size
+
+    Number of bytes queued for sending. This field strictly shows how much
+    information is currently queued.
+
+.. c:member:: size_t uv_udp_t.send_queue_count
+
+    Number of send requests currently in the queue awaiting to be processed.
+
+.. c:member:: uv_udp_t* uv_udp_send_t.handle
+
+    UDP handle where this send request is taking place.
+
+.. seealso:: The :c:type:`uv_handle_t` members also apply.
+
+
+API
+---
+
+.. c:function:: int uv_udp_init(uv_loop_t* loop, uv_udp_t* handle)
+
+    Initialize a new UDP handle. The actual socket is created lazily.
+    Returns 0 on success.
+
+.. c:function:: int uv_udp_init_ex(uv_loop_t* loop, uv_udp_t* handle, unsigned int flags)
+
+    Initialize the handle with the specified flags. The lower 8 bits of the `flags`
+    parameter are used as the socket domain. A socket will be created for the given domain.
+    If the specified domain is ``AF_UNSPEC`` no socket is created, just like :c:func:`uv_udp_init`.
+
+    The remaining bits can be used to set one of these flags:
+
+    * `UV_UDP_RECVMMSG`: if set, and the platform supports it, :man:`recvmmsg(2)` will
+      be used.
+
+    .. versionadded:: 1.7.0
+    .. versionchanged:: 1.37.0 added the `UV_UDP_RECVMMSG` flag.
+
+.. c:function:: int uv_udp_open(uv_udp_t* handle, uv_os_sock_t sock)
+
+    Opens an existing file descriptor or Windows SOCKET as a UDP handle.
+
+    Unix only:
+    The only requirement of the `sock` argument is that it follows the datagram
+    contract (works in unconnected mode, supports sendmsg()/recvmsg(), etc).
+    In other words, other datagram-type sockets like raw sockets or netlink
+    sockets can also be passed to this function.
+
+    .. versionchanged:: 1.2.1 the file descriptor is set to non-blocking mode.
+
+    .. note::
+        The passed file descriptor or SOCKET is not checked for its type, but
+        it's required that it represents a valid datagram socket.
+
+.. c:function:: int uv_udp_bind(uv_udp_t* handle, const struct sockaddr* addr, unsigned int flags)
+
+    Bind the UDP handle to an IP address and port.
+
+    :param handle: UDP handle. Should have been initialized with
+        :c:func:`uv_udp_init`.
+
+    :param addr: `struct sockaddr_in` or `struct sockaddr_in6`
+        with the address and port to bind to.
+
+    :param flags: Indicate how the socket will be bound,
+        ``UV_UDP_IPV6ONLY``, ``UV_UDP_REUSEADDR``, and ``UV_UDP_RECVERR``
+        are supported.
+
+    :returns: 0 on success, or an error code < 0 on failure.
+
+.. c:function:: int uv_udp_connect(uv_udp_t* handle, const struct sockaddr* addr)
+
+    Associate the UDP handle to a remote address and port, so every
+    message sent by this handle is automatically sent to that destination.
+    Calling this function with a `NULL` `addr` disconnects the handle.
+    Trying to call `uv_udp_connect()` on an already connected handle will result
+    in an `UV_EISCONN` error. Trying to disconnect a handle that is not
+    connected will return an `UV_ENOTCONN` error.
+
+    :param handle: UDP handle. Should have been initialized with
+        :c:func:`uv_udp_init`.
+
+    :param addr: `struct sockaddr_in` or `struct sockaddr_in6`
+        with the address and port to associate to.
+
+    :returns: 0 on success, or an error code < 0 on failure.
+

+
+.. c:function:: int uv_udp_getpeername(const uv_udp_t* handle, struct sockaddr* name, int* namelen)
+
+    Get the remote IP and port of the UDP handle on connected UDP handles.
+    On unconnected handles, it returns `UV_ENOTCONN`.
+
+    :param handle: UDP handle. Should have been initialized with

+        output it indicates how much of it was filled.
+
+    :returns: 0 on success, or an error code < 0 on failure
+
+    .. versionadded:: 1.27.0
+
+.. c:function:: int uv_udp_getsockname(const uv_udp_t* handle, struct sockaddr* name, int* namelen)
+
+    Get the local IP and port of the UDP handle.

+        :c:func:`uv_udp_init` and bound.
+
+    :param name: Pointer to the structure to be filled with the address data.

+
+    Set membership for a source-specific multicast group.
+

+
+    Set IP multicast loop flag. Makes multicast packets loop back to

+.. c:function:: int uv_udp_send(uv_udp_send_t* req, uv_udp_t* handle, const uv_buf_t bufs[], unsigned int nbufs, const struct sockaddr* addr, uv_udp_send_cb send_cb)
+
+    Send data over the UDP socket. If the socket has not previously been bound
+    with :c:func:`uv_udp_bind` it will be bound to 0.0.0.0
+    (the "all interfaces" IPv4 address) and a random port number.
+
+    On Windows if the `addr` is initialized to point to an unspecified address
+    (``0.0.0.0`` or ``::``) it will be changed to point to ``localhost``.
+    This is done to match the behavior of Linux systems.
+
+    For connected UDP handles, `addr` must be set to `NULL`, otherwise it will
+    return `UV_EISCONN` error.
+
+    For connectionless UDP handles, `addr` cannot be `NULL`, otherwise it will
+    return `UV_EDESTADDRREQ` error.
+
+    :param req: UDP request handle. Need not be initialized.
+

+
+    :returns: 0 on success, or an error code < 0 on failure.
+
+    .. versionchanged:: 1.19.0 added ``0.0.0.0`` and ``::`` to ``localhost``
+        mapping
+
+    .. versionchanged:: 1.27.0 added support for connected sockets
+
+.. c:function:: int uv_udp_try_send(uv_udp_t* handle, const uv_buf_t bufs[], unsigned int nbufs, const struct sockaddr* addr)
+
+    Same as :c:func:`uv_udp_send`, but won't queue a send request if it can't
+    be completed immediately.
+
+    For connected UDP handles, `addr` must be set to `NULL`, otherwise it will
+    return `UV_EISCONN` error.
+
+    For connectionless UDP handles, `addr` cannot be `NULL`, otherwise it will
+    return `UV_EDESTADDRREQ` error.
+
+    :returns: >= 0: number of bytes sent (it matches the given buffer size).
+        < 0: negative error code (``UV_EAGAIN`` is returned when the message
+        can't be sent immediately).

+
+.. c:function:: int uv_udp_recv_start(uv_udp_t* handle, uv_alloc_cb alloc_cb, uv_udp_recv_cb recv_cb)
+
+    Prepare for receiving data. If the socket has not previously been bound
+    with :c:func:`uv_udp_bind` it is bound to 0.0.0.0 (the "all interfaces"
+    IPv4 address) and a random port number.
+
+    :param handle: UDP handle. Should have been initialized with
+        :c:func:`uv_udp_init`.
+
+    :param alloc_cb: Callback to invoke when temporary storage is needed.
+
+    :param recv_cb: Callback to invoke with received data.
+
+    :returns: 0 on success, or an error code < 0 on failure.
+
+    .. note::
+        When using :man:`recvmmsg(2)`, the number of messages received at a time is limited
+        by the number of max size dgrams that will fit into the buffer allocated in `alloc_cb`, and
+        `suggested_size` in `alloc_cb` for udp_recv is always set to the size of 1 max size dgram.
+
+    .. versionchanged:: 1.35.0 added support for :man:`recvmmsg(2)` on supported platforms).
+                        The use of this feature requires a buffer larger than
+                        2 * 64KB to be passed to `alloc_cb`.
+    .. versionchanged:: 1.37.0 :man:`recvmmsg(2)` support is no longer enabled implicitly,
+                        it must be explicitly requested by passing the `UV_UDP_RECVMMSG` flag to

+                        allocated for the current handle/platform.
+
+.. c:function:: int uv_udp_using_recvmmsg(uv_udp_t* handle)
+
+    Returns 1 if the UDP handle was created with the `UV_UDP_RECVMMSG` flag
+    and the platform supports :man:`recvmmsg(2)`, 0 otherwise.
+
+    .. versionadded:: 1.39.0
+
+.. c:function:: int uv_udp_recv_stop(uv_udp_t* handle)
+
+    Stop listening for incoming datagrams.
+
+    :param handle: UDP handle. Should have been initialized with

+
+    :returns: 0 on success, or an error code < 0 on failure.

+Version-checking macros and functions
+=====================================
+
+Starting with version 1.0.0 libuv follows the `semantic versioning`_
+scheme. This means that new APIs can be introduced throughout the lifetime of
+a major release. In this section you'll find all macros and functions that
+will allow you to write or compile code conditionally, in order to work with
+multiple libuv versions.
+
+.. _semantic versioning: https://semver.org
+
+
+Macros
+------
+
+.. c:macro:: UV_VERSION_MAJOR
+
+    libuv version's major number.
+
+.. c:macro:: UV_VERSION_MINOR
+
+    libuv version's minor number.
+
+.. c:macro:: UV_VERSION_PATCH
+
+    libuv version's patch number.
+
+.. c:macro:: UV_VERSION_IS_RELEASE
+
+    Set to 1 to indicate a release version of libuv, 0 for a development
+    snapshot.
+
+.. c:macro:: UV_VERSION_SUFFIX
+
+    libuv version suffix. Certain development releases such as Release Candidates
+    might have a suffix such as "rc".
+
+.. c:macro:: UV_VERSION_HEX
+
+    Returns the libuv version packed into a single integer. 8 bits are used for
+    each component, with the patch number stored in the 8 least significant
+    bits. E.g. for libuv 1.2.3 this would be 0x010203.
+
+    .. versionadded:: 1.7.0
+
+
+Functions
+---------
+
+.. c:function:: unsigned int uv_version(void)
+
+    Returns :c:macro:`UV_VERSION_HEX`.
+
+.. c:function:: const char* uv_version_string(void)
+
+    Returns the libuv version number as a string. For non-release versions the
+    version suffix is included.

+ * This file defines data structures for different types of trees:
+ * splay trees and red-black trees.
+ *
+ * A splay tree is a self-organizing data structure.  Every operation
+ * on the tree causes a splay to happen.  The splay moves the requested
+ * node to the root of the tree and partly rebalances it.
+ *
+ * This has the benefit that request locality causes faster lookups as
+ * the requested nodes move to the top of the tree.  On the other hand,
+ * every lookup causes memory writes.
+ *
+ * The Balance Theorem bounds the total access time for m operations
+ * and n inserts on an initially empty tree as O((m + n)lg n).  The
+ * amortized cost for a sequence of m accesses to a splay tree is O(lg n);
+ *
+ * A red-black tree is a binary search tree with the node color as an
+ * extra attribute.  It fulfills a set of conditions:
+ *  - every search path from the root to a leaf consists of the
+ *    same number of black nodes,
+ *  - each red node (except for the root) has a black parent,
+ *  - each leaf node is black.
+ *
+ * Every operation on a red-black tree is bounded as O(lg n).
+ * The maximum height of a red-black tree is 2lg (n+1).

+# SYNOPSIS
+#
+#   AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
+#
+# DESCRIPTION
+#
+#   This macro figures out how to build C programs using POSIX threads. It
+#   sets the PTHREAD_LIBS output variable to the threads library and linker
+#   flags, and the PTHREAD_CFLAGS output variable to any special C compiler
+#   flags that are needed. (The user can also force certain compiler
+#   flags/libs to be tested by setting these environment variables.)
+#
+#   Also sets PTHREAD_CC to any special C compiler that is needed for
+#   multi-threaded programs (defaults to the value of CC otherwise). (This
+#   is necessary on AIX to use the special cc_r compiler alias.)
+#
+#   NOTE: You are assumed to not only compile your program with these flags,
+#   but also to link with them as well. For example, you might link with
+#   $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
+#
+#   If you are only building threaded programs, you may wish to use these
+#   variables in your default LIBS, CFLAGS, and CC:
+#
+#     LIBS="$PTHREAD_LIBS $LIBS"
+#     CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
+#     CC="$PTHREAD_CC"
+#
+#   In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
+#   has a nonstandard name, this macro defines PTHREAD_CREATE_JOINABLE to
+#   that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
+#
+#   Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the
+#   PTHREAD_PRIO_INHERIT symbol is defined when compiling with
+#   PTHREAD_CFLAGS.
+#
+#   ACTION-IF-FOUND is a list of shell commands to run if a threads library
+#   is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
+#   is not found. If ACTION-IF-FOUND is not specified, the default action
+#   will define HAVE_PTHREAD.
+#
+#   Please let the authors know if this macro fails on any platform, or if
+#   you have any other suggestions or comments. This macro was based on work
+#   by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
+#   from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
+#   Alejandro Forero Cuervo to the autoconf macro repository. We are also
+#   grateful for the helpful feedback of numerous users.

+   * We try to use pread() and fall back to regular read() if the source fd

+   *
+   * If we get EAGAIN when writing to the target fd, we poll() on it until
+   * it becomes writable again.
+   *
+   * FIXME: If we get a write error when use_pread==1, it should be safe to
+   *        return the number of sent bytes instead of an error because pread()
+   *        is, in theory, idempotent. However, special files in /dev or /proc
+   *        may support pread() but not necessarily return the same data on
+   *        successive reads.

+ * Furthermore, it tries to follow the semantics that cmd.exe, with this
+ * exception that PATHEXT environment variable isn't used. Since CreateProcess
+ * can start only .com and .exe files, only those extensions are tried. This
+ * behavior equals that of msvcrt's spawn functions.
+ *
+ * - Do not search the path if the filename already contains a path (either
+ *   relative or absolute).
+ *
+ * - If there's really only a filename, check the current directory for file,
+ *   then search all path directories.
+ *
+ * - If filename specified has *any* extension, search for the file with the
+ *   specified extension first.
+ *
+ * - If the literal filename is not found in a directory, try *appending*
+ *   (not replacing) .com first and then .exe.
+ *
+ * - The path variable may contain relative paths; relative paths are relative
+ *   to the cwd.
+ *
+ * - Directories in path may or may not end with a trailing backslash.
+ *
+ * - CMD does not trim leading/trailing whitespace from path/pathex entries
+ *   nor from the environment variables as a whole.
+ *
+ * - When cmd.exe cannot read a directory, it will just skip it and go on
+ *   searching. However, unlike posix-y systems, it will happily try to run a
+ *   file that is not readable/executable; if the spawn fails it will not
+ *   continue searching.
+ *
+ * UNC path support: we are dealing with UNC paths in both the path and the
+ * filename. This is a deviation from what cmd.exe does (it does not let you
+ * start a program by specifying an UNC path on the command line) but this is

+/* Tests commented out with XXX are ones that are failing on Linux */
+
+/*
+ * Purpose of this test is to check semantics of starting and stopping
+ * prepare, check and idle watchers.
+ *
+ * - A watcher must be able to safely stop or close itself;
+ * - Once a watcher is stopped or closed its callback should never be called.
+ * - If a watcher is closed, it is implicitly stopped and its close_cb should
+ *   be called exactly once.
+ * - A watcher can safely start and stop other watchers of the same type.
+ * - Prepare and check watchers are called once per event loop iterations.
+ * - All active idle watchers are queued when the event loop has no more work
+ *   to do. This is done repeatedly until all idle watchers are inactive.
+ * - If a watcher starts another watcher of the same type its callback is not
+ *   immediately queued. For check and prepare watchers, that means that if
+ *   a watcher makes another of the same type active, it'll not be called until
+ *   the next event loop iteration. For idle. watchers this means that the
+ *   newly activated idle watcher might not be queued immediately.
+ * - Prepare, check, idle watchers keep the event loop alive even when they're
+ *   not active.
+ *
+ * This is what the test globally does:
+ *
+ * - prepare_1 is always active and counts event loop iterations. It also
+ *   creates and starts prepare_2 every other iteration. Finally it verifies
+ *   that no idle watchers are active before polling.
+ * - prepare_2 is started by prepare_1 every other iteration. It immediately
+ *   stops itself. It verifies that a watcher is not queued immediately
+ *   if created by another watcher of the same type.
+ * - There's a check watcher that stops the event loop after a certain number
+ *   of iterations. It starts a varying number of idle_1 watchers.
+ * - Idle_1 watchers stop themselves after being called a few times. All idle_1
+ *   watchers try to start the idle_2 watcher if it is not already started or
+ *   awaiting its close callback.
+ * - The idle_2 watcher always exists but immediately closes itself after
+ *   being started by a check_1 watcher. It verifies that a watcher is
+ *   implicitly stopped when closed, and that a watcher can close itself
+ *   safely.
+ * - There is a repeating timer. It does not keep the event loop alive
+ *   (ev_unref) but makes sure that the loop keeps polling the system for
+ *   events.

+ * The idea behind the test is as follows.
+ * Certain handle types are stored in a queue internally.
+ * Extra care should be taken for removal of a handle from the queue while iterating over the queue.
+ * (i.e., QUEUE_REMOVE() called within QUEUE_FOREACH())
+ * This usually happens when someone closes or stops a handle from within its callback.
+ * So we need to check that we haven't screwed the queue on close/stop.
+ * To do so we do the following (for each handle type):
+ *  1. Create and start 3 handles (#0, #1, and #2).
+ *
+ *     The queue after the start() calls:
+ *     ..=> [queue head] <=> [handle] <=> [handle #1] <=> [handle] <=..
+ *
+ *  2. Trigger handles to fire (for uv_idle_t, uv_prepare_t, and uv_check_t there is nothing to do).
+ *
+ *  3. In the callback for the first-executed handle (#0 or #2 depending on handle type)
+ *     stop the handle and the next one (#1).
+ *     (for uv_idle_t, uv_prepare_t, and uv_check_t callbacks are executed in the reverse order as they are start()'ed,
+ *     so callback for handle #2 will be called first)
+ *
+ *     The queue after the stop() calls:
+ *                                correct foreach "next"  |
+ *                                                       \/
+ *     ..=> [queue head] <==============================> [handle] <=..
+ *          [          ] <-  [handle] <=> [handle #1]  -> [      ]
+ *                                       /\
+ *                  wrong foreach "next"  |
+ *
+ *  4. The callback for handle #1 shouldn't be called because the handle #1 is stopped in the previous step.
+ *     However, if QUEUE_REMOVE() is not handled properly within QUEUE_FOREACH(), the callback _will_ be called.

-Metrics operations
-======================
-
-libuv provides a metrics API to track the amount of time the event loop has
-spent idle in the kernel's event provider.
-
-API
----
-
-.. c:function:: uint64_t uv_metrics_idle_time(uv_loop_t* loop)
-
-    Retrieve the amount of time the event loop has been idle in the kernel's
-    event provider (e.g. ``epoll_wait``). The call is thread safe.
-
-    The return value is the accumulated time spent idle in the kernel's event
-    provider starting from when the :c:type:`uv_loop_t` was configured to
-    collect the idle time.
-
-    .. note::
-        The event loop will not begin accumulating the event provider's idle
-        time until calling :c:type:`uv_loop_configure` with
-        :c:type:`UV_METRICS_IDLE_TIME`.
-
-    .. versionadded:: 1.39.0

+libuv provides a metrics API to track various internal operations of the event
+loop.
+
+
+Data types
+----------
+
+.. c:type:: uv_metrics_t
+
+    The struct that contains event loop metrics. It is recommended to retrieve
+    these metrics in a :c:type:`uv_prepare_cb` in order to make sure there are
+    no inconsistencies with the metrics counters.

+
+.. c:member:: uint64_t uv_metrics_t.loop_count
+
+    Number of event loop iterations.
+
+.. c:member:: uint64_t uv_metrics_t.events
+
+    Number of events that have been processed by the event handler.
+
+.. c:member:: uint64_t uv_metrics_t.events_waiting
+
+    Number of events that were waiting to be processed when the event provider
+    was called.

+
+API
+---
+
+.. c:function:: uint64_t uv_metrics_idle_time(uv_loop_t* loop)
+
+    Retrieve the amount of time the event loop has been idle in the kernel's
+    event provider (e.g. ``epoll_wait``). The call is thread safe.
+
+    The return value is the accumulated time spent idle in the kernel's event
+    provider starting from when the :c:type:`uv_loop_t` was configured to
+    collect the idle time.
+
+    .. note::
+        The event loop will not begin accumulating the event provider's idle
+        time until calling :c:type:`uv_loop_configure` with
+        :c:type:`UV_METRICS_IDLE_TIME`.
+
+    .. versionadded:: 1.39.0
+
+.. c:function:: int uv_metrics_info(uv_loop_t* loop, uv_metrics_t* metrics)

-# CONTRIBUTING
-
-The libuv project welcomes new contributors. This document will guide you
-through the process.
-
-
-### FORK
-
-Fork the project [on GitHub](https://github.com/libuv/libuv) and check out
-your copy.
-
-```
-$ git clone https://github.com/username/libuv.git
-$ cd libuv
-$ git remote add upstream https://github.com/libuv/libuv.git
-```
-
-Now decide if you want your feature or bug fix to go into the master branch
-or the stable branch.  As a rule of thumb, bug fixes go into the stable branch
-while new features go into the master branch.
-
-The stable branch is effectively frozen; patches that change the libuv
-API/ABI or affect the run-time behavior of applications get rejected.
-
-In case of doubt, open an issue in the [issue tracker][], post your question
-to the [libuv discussions forum], or message the [libuv mailing list].
-
-Especially do so if you plan to work on something big. Nothing is more
-frustrating than seeing your hard work go to waste because your vision does not
-align with that of the [project maintainers].
-
-
-### BRANCH
-
-Okay, so you have decided on the proper branch.  Create a feature branch
-and start hacking:
-
-```
-$ git checkout -b my-feature-branch -t origin/v1.x
-```
-
-(Where v1.x is the latest stable branch as of this writing.)
-
-### CODE
-
-Please adhere to libuv's code style. In general it follows the conventions from
-the [Google C/C++ style guide]. Some of the key points, as well as some
-additional guidelines, are enumerated below.
-
-* Code that is specific to unix-y platforms should be placed in `src/unix`, and
-  declarations go into `include/uv/unix.h`.
-
-* Source code that is Windows-specific goes into `src/win`, and related
-  publicly exported types, functions and macro declarations should generally
-  be declared in `include/uv/win.h`.
-
-* Names should be descriptive and concise.
-
-* All the symbols and types that libuv makes available publicly should be
-  prefixed with `uv_` (or `UV_` in case of macros).
-
-* Internal, non-static functions should be prefixed with `uv__`.
-
-* Use two spaces and no tabs.
-
-* Lines should be wrapped at 80 characters.
-
-* Ensure that lines have no trailing whitespace, and use unix-style (LF) line
-  endings.
-
-* Use C89-compliant syntax. In other words, variables can only be declared at
-  the top of a scope (function, if/for/while-block).
-
-* When writing comments, use properly constructed sentences, including
-  punctuation.
-
-* When documenting APIs and/or source code, don't make assumptions or make
-  implications about race, gender, religion, political orientation or anything
-  else that isn't relevant to the project.
-
-* Remember that source code usually gets written once and read often: ensure
-  the reader doesn't have to make guesses. Make sure that the purpose and inner
-  logic are either obvious to a reasonably skilled professional, or add a
-  comment that explains it.
-
-
-### COMMIT
-
-Make sure git knows your name and email address:
-
-```
-$ git config --global user.name "J. Random User"
-$ git config --global user.email "j.random.user@example.com"
-```
-
-Writing good commit logs is important.  A commit log should describe what
-changed and why.  Follow these guidelines when writing one:
-
-1. The first line should be 50 characters or less and contain a short
-   description of the change prefixed with the name of the changed
-   subsystem (e.g. "net: add localAddress and localPort to Socket").
-2. Keep the second line blank.
-3. Wrap all other lines at 72 columns.
-
-A good commit log looks like this:
-
-```
-subsystem: explaining the commit in one line
-
-Body of commit message is a few lines of text, explaining things
-in more detail, possibly giving some background about the issue
-being fixed, etc etc.
-
-The body of the commit message can be several paragraphs, and
-please do proper word-wrap and keep columns shorter than about
-72 characters or so. That way `git log` will show things
-nicely even when it is indented.
-```
-
-The header line should be meaningful; it is what other people see when they
-run `git shortlog` or `git log --oneline`.
-
-Check the output of `git log --oneline files_that_you_changed` to find out
-what subsystem (or subsystems) your changes touch.
-
-
-### REBASE
-
-Use `git rebase` (not `git merge`) to sync your work from time to time.
-
-```
-$ git fetch upstream
-$ git rebase upstream/v1.x  # or upstream/master
-```
-
-
-### TEST
-
-Bug fixes and features should come with tests.  Add your tests in the
-`test/` directory. Each new test needs to be registered in `test/test-list.h`.
-
-If you add a new test file, it needs to be registered in three places:
-- `CMakeLists.txt`: add the file's name to the `uv_test_sources` list.
-- `Makefile.am`: add the file's name to the `test_run_tests_SOURCES` list.
-
-Look at other tests to see how they should be structured (license boilerplate,
-the way entry points are declared, etc.).
-
-Check README.md file to find out how to run the test suite and make sure that
-there are no test regressions.
-
-### PUSH
-
-```
-$ git push origin my-feature-branch
-```
-
-Go to https://github.com/username/libuv and select your feature branch.  Click
-the 'Pull Request' button and fill out the form.
-
-Pull requests are usually reviewed within a few days.  If there are comments
-to address, apply your changes in a separate commit and push that to your
-feature branch.  Post a comment in the pull request afterwards; GitHub does
-not send out notifications when you add commits.

-Section 2 -- Scope.
-
-  a. License grant.
-
-       1. Subject to the terms and conditions of this Public License,
-          the Licensor hereby grants You a worldwide, royalty-free,
-          non-sublicensable, non-exclusive, irrevocable license to
-          exercise the Licensed Rights in the Licensed Material to:
-
-            a. reproduce and Share the Licensed Material, in whole or
-               in part; and
-
-            b. produce, reproduce, and Share Adapted Material.
-
-       2. Exceptions and Limitations. For the avoidance of doubt, where
-          Exceptions and Limitations apply to Your use, this Public
-          License does not apply, and You do not need to comply with
-          its terms and conditions.
-
-       3. Term. The term of this Public License is specified in Section
-          6(a).
-
-       4. Media and formats; technical modifications allowed. The
-          Licensor authorizes You to exercise the Licensed Rights in
-          all media and formats whether now known or hereafter created,
-          and to make technical modifications necessary to do so. The
-          Licensor waives and/or agrees not to assert any right or
-          authority to forbid You from making technical modifications
-          necessary to exercise the Licensed Rights, including
-          technical modifications necessary to circumvent Effective
-          Technological Measures. For purposes of this Public License,
-          simply making modifications authorized by this Section 2(a)
-          (4) never produces Adapted Material.
-
-       5. Downstream recipients.
-
-            a. Offer from the Licensor -- Licensed Material. Every
-               recipient of the Licensed Material automatically
-               receives an offer from the Licensor to exercise the
-               Licensed Rights under the terms and conditions of this
-               Public License.
-
-            b. No downstream restrictions. You may not offer or impose
-               any additional or different terms or conditions on, or
-               apply any Effective Technological Measures to, the
-               Licensed Material if doing so restricts exercise of the
-               Licensed Rights by any recipient of the Licensed
-               Material.
-
-       6. No endorsement. Nothing in this Public License constitutes or
-          may be construed as permission to assert or imply that You
-          are, or that Your use of the Licensed Material is, connected
-          with, or sponsored, endorsed, or granted official status by,
-          the Licensor or others designated to receive attribution as
-          provided in Section 3(a)(1)(A)(i).
-
-  b. Other rights.
-
-       1. Moral rights, such as the right of integrity, are not
-          licensed under this Public License, nor are publicity,
-          privacy, and/or other similar personality rights; however, to
-          the extent possible, the Licensor waives and/or agrees not to
-          assert any such rights held by the Licensor to the limited
-          extent necessary to allow You to exercise the Licensed
-          Rights, but not otherwise.
-
-       2. Patent and trademark rights are not licensed under this
-          Public License.
-
-       3. To the extent possible, the Licensor waives any right to
-          collect royalties from You for the exercise of the Licensed
-          Rights, whether directly or through a collecting society
-          under any voluntary or waivable statutory or compulsory
-          licensing scheme. In all other cases the Licensor expressly
-          reserves any right to collect such royalties.
-
-
-Section 3 -- License Conditions.
-
-Your exercise of the Licensed Rights is expressly made subject to the
-following conditions.
-
-  a. Attribution.
-
-       1. If You Share the Licensed Material (including in modified
-          form), You must:
-
-            a. retain the following if it is supplied by the Licensor
-               with the Licensed Material:
-
-                 i. identification of the creator(s) of the Licensed
-                    Material and any others designated to receive
-                    attribution, in any reasonable manner requested by
-                    the Licensor (including by pseudonym if
-                    designated);
-
-                ii. a copyright notice;
-
-               iii. a notice that refers to this Public License;
-
-                iv. a notice that refers to the disclaimer of
-                    warranties;
-
-                 v. a URI or hyperlink to the Licensed Material to the
-                    extent reasonably practicable;
-
-            b. indicate if You modified the Licensed Material and
-               retain an indication of any previous modifications; and
-
-            c. indicate the Licensed Material is licensed under this
-               Public License, and include the text of, or the URI or
-               hyperlink to, this Public License.
-
-       2. You may satisfy the conditions in Section 3(a)(1) in any
-          reasonable manner based on the medium, means, and context in
-          which You Share the Licensed Material. For example, it may be
-          reasonable to satisfy the conditions by providing a URI or
-          hyperlink to a resource that includes the required
-          information.
-
-       3. If requested by the Licensor, You must remove any of the
-          information required by Section 3(a)(1)(A) to the extent
-          reasonably practicable.
-
-       4. If You Share Adapted Material You produce, the Adapter's
-          License You apply must not prevent recipients of the Adapted
-          Material from complying with this Public License.
-
-
-Section 4 -- Sui Generis Database Rights.
-
-Where the Licensed Rights include Sui Generis Database Rights that
-apply to Your use of the Licensed Material:
-
-  a. for the avoidance of doubt, Section 2(a)(1) grants You the right
-     to extract, reuse, reproduce, and Share all or a substantial
-     portion of the contents of the database;
-
-  b. if You include all or a substantial portion of the database
-     contents in a database in which You have Sui Generis Database
-     Rights, then the database in which You have Sui Generis Database
-     Rights (but not its individual contents) is Adapted Material; and
-
-  c. You must comply with the conditions in Section 3(a) if You Share
-     all or a substantial portion of the contents of the database.
-
-For the avoidance of doubt, this Section 4 supplements and does not
-replace Your obligations under this Public License where the Licensed
-Rights include other Copyright and Similar Rights.
-
-
-Section 5 -- Disclaimer of Warranties and Limitation of Liability.
-
-  a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE
-     EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS
-     AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF
-     ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS,
-     IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION,
-     WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR
-     PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS,
-     ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT
-     KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT
-     ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.
-
-  b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE
-     TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION,
-     NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT,
-     INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES,
-     COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR
-     USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN
-     ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR
-     DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR
-     IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.
-
-  c. The disclaimer of warranties and limitation of liability provided
-     above shall be interpreted in a manner that, to the extent
-     possible, most closely approximates an absolute disclaimer and
-     waiver of all liability.
-
-
-Section 6 -- Term and Termination.
-
-  a. This Public License applies for the term of the Copyright and
-     Similar Rights licensed here. However, if You fail to comply with
-     this Public License, then Your rights under this Public License
-     terminate automatically.
-
-  b. Where Your right to use the Licensed Material has terminated under
-     Section 6(a), it reinstates:
-
-       1. automatically as of the date the violation is cured, provided
-          it is cured within 30 days of Your discovery of the
-          violation; or
-
-       2. upon express reinstatement by the Licensor.
-
-     For the avoidance of doubt, this Section 6(b) does not affect any
-     right the Licensor may have to seek remedies for Your violations
-     of this Public License.
-
-  c. For the avoidance of doubt, the Licensor may also offer the
-     Licensed Material under separate terms or conditions or stop
-     distributing the Licensed Material at any time; however, doing so
-     will not terminate this Public License.
-
-  d. Sections 1, 5, 6, 7, and 8 survive termination of this Public
-     License.
-
-
-Section 7 -- Other Terms and Conditions.
-
-  a. The Licensor shall not be bound by any additional or different
-     terms or conditions communicated by You unless expressly agreed.
-
-  b. Any arrangements, understandings, or agreements regarding the
-     Licensed Material not stated herein are separate from and
-     independent of the terms and conditions of this Public License.
-
-
-Section 8 -- Interpretation.
-
-  a. For the avoidance of doubt, this Public License does not, and
-     shall not be interpreted to, reduce, limit, restrict, or impose
-     conditions on any use of the Licensed Material that could lawfully
-     be made without permission under this Public License.
-
-  b. To the extent possible, if any provision of this Public License is
-     deemed unenforceable, it shall be automatically reformed to the
-     minimum extent necessary to make it enforceable. If the provision
-     cannot be reformed, it shall be severed from this Public License
-     without affecting the enforceability of the remaining terms and
-     conditions.
-
-  c. No term or condition of this Public License will be waived and no
-     failure to comply consented to unless expressly agreed to by the
-     Licensor.
-
-  d. Nothing in this Public License constitutes or may be interpreted
-     as a limitation upon, or waiver of, any privileges and immunities
-     that apply to the Licensor or You, including from the legal
-     processes of any jurisdiction or authority.

-## Storing a maintainer key in Git
-
-It's quite handy to store a maintainer's signature as a git blob, and have
-that object tagged and signed with such key.
-
-Export your public key:
-
-    $ gpg --armor --export saghul@gmail.com > saghul.asc
-
-Store it as a blob on the repo:
-
-    $ git hash-object -w saghul.asc
-
-The previous command returns a hash, copy it. For the sake of this explanation,
-we'll assume it's 'abcd1234'. Storing the blob in git is not enough, it could
-be garbage collected since nothing references it, so we'll create a tag for it:
-
-    $ git tag -s pubkey-saghul abcd1234
-
-Commit the changes and push:
-
-    $ git push origin pubkey-saghul

-## Overview
-
-libuv is a multi-platform support library with a focus on asynchronous I/O. It
-was primarily developed for use by [Node.js][], but it's also
-used by [Luvit](http://luvit.io/), [Julia](http://julialang.org/),
-[uvloop](https://github.com/MagicStack/uvloop), and [others](https://github.com/libuv/libuv/blob/v1.x/LINKS.md).
-
-## Feature highlights
-
- * Full-featured event loop backed by epoll, kqueue, IOCP, event ports.
-
- * Asynchronous TCP and UDP sockets
-
- * Asynchronous DNS resolution
-
- * Asynchronous file and file system operations
-
- * File system events
-
- * ANSI escape code controlled TTY
-
- * IPC with socket sharing, using Unix domain sockets or named pipes (Windows)
-
- * Child processes
-
- * Thread pool
-
- * Signal handling
-
- * High resolution clock
-
- * Threading and synchronization primitives
-
-## Versioning
-
-Starting with version 1.0.0 libuv follows the [semantic versioning](http://semver.org/)
-scheme. The API change and backwards compatibility rules are those indicated by
-SemVer. libuv will keep a stable ABI across major releases.
-
-The ABI/API changes can be tracked [here](http://abi-laboratory.pro/tracker/timeline/libuv/).
-
-## Licensing
-
-libuv is licensed under the MIT license. Check the [LICENSE](LICENSE) and
-[LICENSE-extra](LICENSE-extra) files.
-
-The documentation is licensed under the CC BY 4.0 license. Check the
-[LICENSE-docs file](LICENSE-docs).

-## Documentation
-
-### Official documentation
-
-Located in the docs/ subdirectory. It uses the [Sphinx](http://sphinx-doc.org/)
-framework, which makes it possible to build the documentation in multiple
-formats.
-
-Show different supported building options:
-
-```bash
-$ make help
-```
-
-Build documentation as HTML:
-
-```bash
-$ make html
-```
-
-Build documentation as HTML and live reload it when it changes (this requires
-sphinx-autobuild to be installed and is only supported on Unix):
-
-```bash
-$ make livehtml
-```
-
-Build documentation as man pages:
-
-```bash
-$ make man
-```
-
-Build documentation as ePub:
-
-```bash
-$ make epub
-```
-
-NOTE: Windows users need to use make.bat instead of plain 'make'.
-
-Documentation can be browsed online [here](http://docs.libuv.org).
-
-The [tests and benchmarks](https://github.com/libuv/libuv/tree/master/test)
-also serve as API specification and usage examples.
-
-### Other resources
-
- * [LXJS 2012 talk](http://www.youtube.com/watch?v=nGn60vDSxQ4)
-   &mdash; High-level introductory talk about libuv.
- * [libuv-dox](https://github.com/thlorenz/libuv-dox)
-   &mdash; Documenting types and methods of libuv, mostly by reading uv.h.
- * [learnuv](https://github.com/thlorenz/learnuv)
-   &mdash; Learn uv for fun and profit, a self guided workshop to libuv.
-
-These resources are not handled by libuv maintainers and might be out of
-date. Please verify it before opening new issues.
-
-## Downloading
-
-libuv can be downloaded either from the
-[GitHub repository](https://github.com/libuv/libuv)
-or from the [downloads site](http://dist.libuv.org/dist/).
-
-Before verifying the git tags or signature files, importing the relevant keys
-is necessary. Key IDs are listed in the
-[MAINTAINERS](https://github.com/libuv/libuv/blob/master/MAINTAINERS.md)
-file, but are also available as git blob objects for easier use.
-
-Importing a key the usual way:
-
-```bash
-$ gpg --keyserver pool.sks-keyservers.net --recv-keys AE9BC059
-```
-
-Importing a key from a git blob object:
-
-```bash
-$ git show pubkey-saghul | gpg --import
-```
-
-### Verifying releases
-
-Git tags are signed with the developer's key, they can be verified as follows:
-
-```bash
-$ git verify-tag v1.6.1
-```
-
-Starting with libuv 1.7.0, the tarballs stored in the
-[downloads site](http://dist.libuv.org/dist/) are signed and an accompanying
-signature file sit alongside each. Once both the release tarball and the
-signature file are downloaded, the file can be verified as follows:
-
-```bash
-$ gpg --verify libuv-1.7.0.tar.gz.sign
-```
-
-## Build Instructions
-
-For UNIX-like platforms, including macOS, there are two build methods:
-autotools or [CMake][].
-
-For Windows, [CMake][] is the only supported build method and has the
-following prerequisites:
-
-<details>
-
-* One of:
-  * [Visual C++ Build Tools][]
-  * [Visual Studio 2015 Update 3][], all editions
-    including the Community edition (remember to select
-    "Common Tools for Visual C++ 2015" feature during installation).
-  * [Visual Studio 2017][], any edition (including the Build Tools SKU).
-    **Required Components:** "MSbuild", "VC++ 2017 v141 toolset" and one of the
-    Windows SDKs (10 or 8.1).
-* Basic Unix tools required for some tests,
-  [Git for Windows][] includes Git Bash
-  and tools which can be included in the global `PATH`.
-
-</details>
-
-To build with autotools:
-
-```bash
-$ sh autogen.sh
-$ ./configure
-$ make
-$ make check
-$ make install
-```
-
-To build with [CMake][]:
-
-```bash
-$ mkdir -p build
-
-$ (cd build && cmake .. -DBUILD_TESTING=ON) # generate project with tests
-$ cmake --build build                       # add `-j <n>` with cmake >= 3.12
-
-# Run tests:
-$ (cd build && ctest -C Debug --output-on-failure)
-
-# Or manually run tests:
-$ build/uv_run_tests                        # shared library build
-$ build/uv_run_tests_a                      # static library build
-```
-
-To cross-compile with [CMake][] (unsupported but generally works):
-
-```bash
-$ cmake ../..                 \
-  -DCMAKE_SYSTEM_NAME=Windows \
-  -DCMAKE_SYSTEM_VERSION=6.1  \
-  -DCMAKE_C_COMPILER=i686-w64-mingw32-gcc
-```
-
-### Install with Homebrew
-
-```bash
-$ brew install --HEAD libuv
-```
-
-Note to OS X users:
-
-Make sure that you specify the architecture you wish to build for in the
-"ARCHS" flag. You can specify more than one by delimiting with a space
-(e.g. "x86_64 i386").
-
-### Install with vcpkg
-
-```bash
-$ git clone https://github.com/microsoft/vcpkg.git
-$ ./bootstrap-vcpkg.bat # for powershell
-$ ./bootstrap-vcpkg.sh # for bash
-$ ./vcpkg install libuv
-```
-
-### Running tests
-
-Some tests are timing sensitive. Relaxing test timeouts may be necessary
-on slow or overloaded machines:
-
-```bash
-$ env UV_TEST_TIMEOUT_MULTIPLIER=2 build/uv_run_tests # 10s instead of 5s
-```
-
-#### Run one test
-
-The list of all tests is in `test/test-list.h`.
-
-This invocation will cause the test driver to fork and execute `TEST_NAME` in
-a child process:
-
-```bash
-$ build/uv_run_tests_a TEST_NAME
-```
-
-This invocation will cause the test driver to execute the test in
-the same process:
-
-```bash
-$ build/uv_run_tests_a TEST_NAME TEST_NAME
-```
-
-#### Debugging tools
-
-When running the test from within the test driver process
-(`build/uv_run_tests_a TEST_NAME TEST_NAME`), tools like gdb and valgrind
-work normally.
-
-When running the test from a child of the test driver process
-(`build/uv_run_tests_a TEST_NAME`), use these tools in a fork-aware manner.
-
-##### Fork-aware gdb
-
-Use the [follow-fork-mode](https://sourceware.org/gdb/onlinedocs/gdb/Forks.html) setting:
-
-```
-$ gdb --args build/uv_run_tests_a TEST_NAME
-
-(gdb) set follow-fork-mode child
-...
-```
-
-##### Fork-aware valgrind
-
-Use the `--trace-children=yes` parameter:
-
-```bash
-$ valgrind --trace-children=yes -v --tool=memcheck --leak-check=full --track-origins=yes --leak-resolution=high --show-reachable=yes --log-file=memcheck-%p.log build/uv_run_tests_a TEST_NAME
-```
-
-### Running benchmarks
-
-See the section on running tests.
-The benchmark driver is `./uv_run_benchmarks_a` and the benchmarks are
-listed in `test/benchmark-list.h`.
-
-## Supported Platforms
-
-Check the [SUPPORTED_PLATFORMS file](SUPPORTED_PLATFORMS.md).
-
-### `-fno-strict-aliasing`
-
-It is recommended to turn on the `-fno-strict-aliasing` compiler flag in
-projects that use libuv. The use of ad hoc "inheritance" in the libuv API
-may not be safe in the presence of compiler optimizations that depend on
-strict aliasing.
-
-MSVC does not have an equivalent flag but it also does not appear to need it
-at the time of writing (December 2019.)
-
-### AIX Notes
-
-AIX compilation using IBM XL C/C++ requires version 12.1 or greater.
-
-AIX support for filesystem events requires the non-default IBM `bos.ahafs`
-package to be installed.  This package provides the AIX Event Infrastructure
-that is detected by `autoconf`.
-[IBM documentation](http://www.ibm.com/developerworks/aix/library/au-aix_event_infrastructure/)
-describes the package in more detail.
-
-### z/OS Notes
-
-z/OS compilation requires [ZOSLIB](https://github.com/ibmruntimes/zoslib) to be installed. When building with [CMake][], use the flag `-DZOSLIB_DIR` to specify the path to [ZOSLIB](https://github.com/ibmruntimes/zoslib):
-
-```bash
-$ (cd build && cmake .. -DBUILD_TESTING=ON -DZOSLIB_DIR=/path/to/zoslib)
-$ cmake --build build
-```
-
-z/OS creates System V semaphores and message queues. These persist on the system
-after the process terminates unless the event loop is closed.
-
-Use the `ipcrm` command to manually clear up System V resources.

-
-## Support types
-
-* **Tier 1**: Officially supported and tested with CI. Any contributed patch
-  MUST NOT break such systems. These are supported by @libuv/collaborators.
-
-* **Tier 2**: Officially supported, but not necessarily tested with CI. These
-  systems are maintained to the best of @libuv/collaborators ability,
-  without being a top priority.
-
-* **Tier 3**: Community maintained. These systems may inadvertently break and the
-  community and interested parties are expected to help with the maintenance.
-
-## Adding support for a new platform
-
-**IMPORTANT**: Before attempting to add support for a new platform please open
-an issue about it for discussion.
-
-### Unix
-
-I/O handling is abstracted by an internal `uv__io_t` handle. The new platform
-will need to implement some of the functions, the prototypes are in
-``src/unix/internal.h``.
-
-If the new platform requires extra fields for any handle structure, create a
-new include file in ``include/`` with the name ``uv-theplatform.h`` and add
-the appropriate defines there.
-
-All functionality related to the new platform must be implemented in its own
-file inside ``src/unix/`` unless it's already done in a common file, in which
-case adding an `ifdef` is fine.
-
-Two build systems are supported: autotools and cmake. Ideally both need to be
-supported, but if one of the two does not support the new platform it can be
-left out.
-
-### Windows
-
-Windows is treated as a single platform, so adding support for a new platform
-would mean adding support for a new version.
-
-Compilation and runtime must succeed for the minimum supported version. If a
-new API is to be used, it must be done optionally, only in supported versions.
-
-### Common
-
-Some common notes when adding support for new platforms:
-
-* Generally libuv tries to avoid compile time checks. Do not add any to the
-  autotools based build system or use version checking macros.
-  Dynamically load functions and symbols if they are not supported by the
-  minimum supported version.

-API
----
-
-.. c:function:: int uv_async_init(uv_loop_t* loop, uv_async_t* async, uv_async_cb async_cb)
-
-    Initialize the handle. A NULL callback is allowed.
-
-    :returns: 0 on success, or an error code < 0 on failure.
-
-    .. note::
-        Unlike other handle initialization  functions, it immediately starts the handle.
-
-.. c:function:: int uv_async_send(uv_async_t* async)
-
-    Wake up the event loop and call the async handle's callback.
-
-    :returns: 0 on success, or an error code < 0 on failure.
-
-    .. note::
-        It's safe to call this function from any thread. The callback will be called on the
-        loop thread.
-
-    .. note::
-        :c:func:`uv_async_send` is `async-signal-safe <https://man7.org/linux/man-pages/man7/signal-safety.7.html>`_.
-        It's safe to call this function from a signal handler.
-
-    .. warning::
-        libuv will coalesce calls to :c:func:`uv_async_send`, that is, not every call to it will
-        yield an execution of the callback. For example: if :c:func:`uv_async_send` is called 5
-        times in a row before the callback is called, the callback will only be called once. If
-        :c:func:`uv_async_send` is called again after the callback was called, it will be called
-        again.
-
-.. seealso::
-    The :c:type:`uv_handle_t` API functions also apply.

-Design overview
-===============
-
-libuv is cross-platform support library which was originally written for `Node.js`_. It's designed
-around the event-driven asynchronous I/O model.
-
-.. _Node.js: https://nodejs.org
-
-The library provides much more than a simple abstraction over different I/O polling mechanisms:
-'handles' and 'streams' provide a high level abstraction for sockets and other entities;
-cross-platform file I/O and threading functionality is also provided, amongst other things.
-
-Here is a diagram illustrating the different parts that compose libuv and what subsystem they
-relate to:
-
-.. image:: static/architecture.png
-    :scale: 75%
-    :align: center
-
-
-Handles and requests
-^^^^^^^^^^^^^^^^^^^^
-
-libuv provides users with 2 abstractions to work with, in combination with the event loop:
-handles and requests.
-
-Handles represent long-lived objects capable of performing certain operations while active. Some examples:
-
-- A prepare handle gets its callback called once every loop iteration when active.
-- A TCP server handle that gets its connection callback called every time there is a new connection.
-
-Requests represent (typically) short-lived operations. These operations can be performed over a
-handle: write requests are used to write data on a handle; or standalone: getaddrinfo requests
-don't need a handle they run directly on the loop.
-
-
-The I/O loop
-^^^^^^^^^^^^
-
-The I/O (or event) loop is the central part of libuv. It establishes the content for all I/O
-operations, and it's meant to be tied to a single thread. One can run multiple event loops
-as long as each runs in a different thread. The libuv event loop (or any other API involving
-the loop or handles, for that matter) **is not thread-safe** except where stated otherwise.
-
-The event loop follows the rather usual single threaded asynchronous I/O approach: all (network)
-I/O is performed on non-blocking sockets which are polled using the best mechanism available
-on the given platform: epoll on Linux, kqueue on OSX and other BSDs, event ports on SunOS and IOCP
-on Windows. As part of a loop iteration the loop will block waiting for I/O activity on sockets
-which have been added to the poller and callbacks will be fired indicating socket conditions
-(readable, writable hangup) so handles can read, write or perform the desired I/O operation.
-
-In order to better understand how the event loop operates, the following diagram illustrates all
-stages of a loop iteration:
-
-.. image:: static/loop_iteration.png
-    :scale: 75%
-    :align: center
-
-
-#. The loop concept of 'now' is initially set.
-
-#. Due timers are run if the loop was run with ``UV_RUN_DEFAULT``. All active timers scheduled
-   for a time before the loop's concept of *now* get their callbacks called.
-
-#. If the loop is *alive*  an iteration is started, otherwise the loop will exit immediately. So,
-   when is a loop considered to be *alive*? If a loop has active and ref'd handles, active
-   requests or closing handles it's considered to be *alive*.
-
-#. Pending callbacks are called. All I/O callbacks are called right after polling for I/O, for the
-   most part. There are cases, however, in which calling such a callback is deferred for the next
-   loop iteration. If the previous iteration deferred any I/O callback it will be run at this point.
-
-#. Idle handle callbacks are called. Despite the unfortunate name, idle handles are run on every
-   loop iteration, if they are active.
-
-#. Prepare handle callbacks are called. Prepare handles get their callbacks called right before
-   the loop will block for I/O.
-
-#. Poll timeout is calculated. Before blocking for I/O the loop calculates for how long it should
-   block. These are the rules when calculating the timeout:
-
-        * If the loop was run with the ``UV_RUN_NOWAIT`` flag, the timeout is 0.
-        * If the loop is going to be stopped (:c:func:`uv_stop` was called), the timeout is 0.
-        * If there are no active handles or requests, the timeout is 0.
-        * If there are any idle handles active, the timeout is 0.
-        * If there are any handles pending to be closed, the timeout is 0.
-        * If none of the above cases matches, the timeout of the closest timer is taken, or
-          if there are no active timers, infinity.
-
-#. The loop blocks for I/O. At this point the loop will block for I/O for the duration calculated
-   in the previous step. All I/O related handles that were monitoring a given file descriptor
-   for a read or write operation get their callbacks called at this point.
-
-#. Check handle callbacks are called. Check handles get their callbacks called right after the
-   loop has blocked for I/O. Check handles are essentially the counterpart of prepare handles.
-
-#. Close callbacks are called. If a handle was closed by calling :c:func:`uv_close` it will
-   get the close callback called.
-
-#. The loop concept of 'now' is updated.
-
-#. Due timers are run. Note that 'now' is not updated again until the next loop iteration.
-   So if a timer became due while other timers were being processed, it won't be run until
-   the following event loop iteration.
-
-#. Iteration ends. If the loop was run with ``UV_RUN_NOWAIT`` or ``UV_RUN_ONCE`` modes the
-   iteration ends and :c:func:`uv_run` will return. If the loop was run with ``UV_RUN_DEFAULT``
-   it will continue from the start if it's still *alive*, otherwise it will also end.
-
-
-.. important::
-    libuv uses a thread pool to make asynchronous file I/O operations possible, but
-    network I/O is **always** performed in a single thread, each loop's thread.
-
-.. note::
-    While the polling mechanism is different, libuv makes the execution model consistent
-    across Unix systems and Windows.
-
-
-File I/O
-^^^^^^^^
-
-Unlike network I/O, there are no platform-specific file I/O primitives libuv could rely on,
-so the current approach is to run blocking file I/O operations in a thread pool.
-
-For a thorough explanation of the cross-platform file I/O landscape, check out
-`this post <https://blog.libtorrent.org/2012/10/asynchronous-disk-io/>`_.
-
-libuv currently uses a global thread pool on which all loops can queue work. 3 types of
-operations are currently run on this pool:
-
-    * File system operations
-    * DNS functions (getaddrinfo and getnameinfo)
-    * User specified code via :c:func:`uv_queue_work`
-
-.. warning::
-    See the :c:ref:`threadpool` section for more details, but keep in mind the thread pool size
-    is quite limited.

-Error handling
-==============
-
-In libuv errors are negative numbered constants. As a rule of thumb, whenever
-there is a status parameter, or an API functions returns an integer, a negative
-number will imply an error.
-
-When a function which takes a callback returns an error, the callback will never
-be called.
-
-.. note::
-    Implementation detail: on Unix error codes are the negated `errno` (or `-errno`), while on
-    Windows they are defined by libuv to arbitrary negative numbers.

-File system operations
-======================
-
-libuv provides a wide variety of cross-platform sync and async file system
-operations. All functions defined in this document take a callback, which is
-allowed to be NULL. If the callback is NULL the request is completed synchronously,
-otherwise it will be performed asynchronously.
-
-All file operations are run on the threadpool. See :ref:`threadpool` for information
-on the threadpool size.
-
-Starting with libuv v1.45.0, some file operations on Linux are handed off to
-`io_uring <https://en.wikipedia.org/wiki/Io_uring>` when possible. Apart from
-a (sometimes significant) increase in throughput there should be no change in
-observable behavior. Libuv reverts to using its threadpool when the necessary
-kernel features are unavailable or unsuitable.
-
-.. note::
-     On Windows `uv_fs_*` functions use utf-8 encoding.

-
-    Equivalent to :man:`open(2)`.
-
-    .. note::
-        On Windows libuv uses `CreateFileW` and thus the file is always opened
-        in binary mode. Because of this the O_BINARY and O_TEXT flags are not
-        supported.

-
-.. c:function:: int uv_fs_opendir(uv_loop_t* loop, uv_fs_t* req, const char* path, uv_fs_cb cb)
-
-    Opens `path` as a directory stream. On success, a `uv_dir_t` is allocated
-    and returned via `req->ptr`. This memory is not freed by
-    `uv_fs_req_cleanup()`, although `req->ptr` is set to `NULL`. The allocated
-    memory must be freed by calling `uv_fs_closedir()`. On failure, no memory
-    is allocated.
-
-    The contents of the directory can be iterated over by passing the resulting
-    `uv_dir_t` to `uv_fs_readdir()`.

-    .. versionadded:: 1.28.0
-
-.. c:function:: int uv_fs_readdir(uv_loop_t* loop, uv_fs_t* req, uv_dir_t* dir, uv_fs_cb cb)
-
-    Iterates over the directory stream, `dir`, returned by a successful
-    `uv_fs_opendir()` call. Prior to invoking `uv_fs_readdir()`, the caller
-    must set `dir->dirents` and `dir->nentries`, representing the array of
-    :c:type:`uv_dirent_t` elements used to hold the read directory entries and
-    its size.
-
-    On success, the result is an integer >= 0 representing the number of entries
-    read from the stream.
-
-    .. versionadded:: 1.28.0

-    .. warning::
-        `uv_fs_readdir()` is not thread safe.
-
-    .. note::
-        This function does not return the "." and ".." entries.
-
-    .. note::
-        On success this function allocates memory that must be freed using
-        `uv_fs_req_cleanup()`. `uv_fs_req_cleanup()` must be called before

-
-.. c:function:: int uv_fs_scandir(uv_loop_t* loop, uv_fs_t* req, const char* path, int flags, uv_fs_cb cb)
-.. c:function:: int uv_fs_scandir_next(uv_fs_t* req, uv_dirent_t* ent)
-
-    Equivalent to :man:`scandir(3)`, with a slightly different API. Once the callback
-    for the request is called, the user can use :c:func:`uv_fs_scandir_next` to
-    get `ent` populated with the next directory entry data. When there are no
-    more entries ``UV_EOF`` will be returned.
-
-    .. note::
-        Unlike `scandir(3)`, this function does not return the "." and ".." entries.
-
-    .. note::
-        On Linux, getting the type of an entry is only supported by some file systems (btrfs, ext2,

-
-    Copies a file from `path` to `new_path`. Supported `flags` are described below.
-
-    - `UV_FS_COPYFILE_EXCL`: If present, `uv_fs_copyfile()` will fail with
-      `UV_EEXIST` if the destination path already exists. The default behavior
-      is to overwrite the destination if it exists.
-    - `UV_FS_COPYFILE_FICLONE`: If present, `uv_fs_copyfile()` will attempt to
-      create a copy-on-write reflink. If the underlying platform does not
-      support copy-on-write, or an error occurs while attempting to use
-      copy-on-write, a fallback copy mechanism based on
-      :c:func:`uv_fs_sendfile()` is used.
-    - `UV_FS_COPYFILE_FICLONE_FORCE`: If present, `uv_fs_copyfile()` will

-            cannot be resolved.
-          - Inconsistent casing when using drive letters.
-          - Resolved path bypasses subst'd drives.

-
-.. note::
-    For AIX, the non default IBM bos.ahafs package has to be installed.
-    The AIX Event Infrastructure file system (ahafs) has some limitations:
-
-        - ahafs tracks monitoring per process and is not thread safe. A separate process
-          must be spawned for each monitor for the same event.
-        - Events for file modification (writing to a file) are not received if only the
-          containing folder is watched.
-
-    See documentation_ for more details.
-
-    The z/OS file system events monitoring infrastructure does not notify of file
-    creation/deletion within a directory that is being monitored.
-    See the `IBM Knowledge centre`_ for more details.

-About
-=====
-
-`Nikhil Marathe <https://nikhilism.com>`_ started writing this book one
-afternoon (June 16, 2012) when he didn't feel like programming. He had recently
-been stung by the lack of good documentation on libuv while working on
-`node-taglib <https://github.com/nikhilm/node-taglib>`_. Although reference
-documentation was present, there were no comprehensive tutorials. This book is
-the output of that need and tries to be accurate. That said, the book may have
-mistakes. Pull requests are encouraged.
-
-Nikhil is indebted to Marc Lehmann's comprehensive `man page
-<http://pod.tst.eu/http://cvs.schmorp.de/libev/ev.pod>`_ about libev which
-describes much of the semantics of the two libraries.
-
-This book was made using `Sphinx <https://www.sphinx-doc.org>`_ and `vim
-<https://www.vim.org>`_.
-
-.. note::
-    In 2017 the libuv project incorporated the Nikhil's work into the official
-    documentation and it's maintained there henceforth.

-Basics of libuv
-===============
-
-libuv enforces an **asynchronous**, **event-driven** style of programming.  Its
-core job is to provide an event loop and callback based notifications of I/O
-and other activities.  libuv offers core utilities like timers, non-blocking
-networking support, asynchronous file system access, child processes and more.
-
-Event loops
------------
-
-In event-driven programming, an application expresses interest in certain events
-and respond to them when they occur. The responsibility of gathering events
-from the operating system or monitoring other sources of events is handled by
-libuv, and the user can register callbacks to be invoked when an event occurs.
-The event-loop usually keeps running *forever*. In pseudocode:
-
-.. code-block:: python
-
-    while there are still events to process:
-        e = get the next event
-        if there is a callback associated with e:
-            call the callback
-
-Some examples of events are:
-
-* File is ready for writing
-* A socket has data ready to be read
-* A timer has timed out
-
-This event loop is encapsulated by ``uv_run()`` -- the end-all function when using
-libuv.
-
-The most common activity of systems programs is to deal with input and output,
-rather than a lot of number-crunching. The problem with using conventional
-input/output functions (``read``, ``fprintf``, etc.) is that they are
-**blocking**. The actual write to a hard disk or reading from a network, takes
-a disproportionately long time compared to the speed of the processor. The
-functions don't return until the task is done, so that your program is doing
-nothing. For programs which require high performance this is a major roadblock
-as other activities and other I/O operations are kept waiting.
-
-One of the standard solutions is to use threads. Each blocking I/O operation is
-started in a separate thread (or in a thread pool). When the blocking function
-gets invoked in the thread, the operating system can schedule another thread to run,
-which actually needs the CPU.
-
-The approach followed by libuv uses another style, which is the **asynchronous,
-non-blocking** style. Most modern operating systems provide event notification
-subsystems. For example, a normal ``read`` call on a socket would block until
-the sender actually sent something. Instead, the application can request the
-operating system to watch the socket and put an event notification in the
-queue. The application can inspect the events at its convenience (perhaps doing
-some number crunching before to use the processor to the maximum) and grab the
-data. It is **asynchronous** because the application expressed interest at one
-point, then used the data at another point (in time and space). It is
-**non-blocking** because the application process was free to do other tasks.
-This fits in well with libuv's event-loop approach, since the operating system
-events can be treated as just another libuv event. The non-blocking ensures
-that other events can continue to be handled as fast as they come in [#]_.
-
-.. NOTE::
-
-    How the I/O is run in the background is not of our concern, but due to the
-    way our computer hardware works, with the thread as the basic unit of the
-    processor, libuv and OSes will usually run background/worker threads and/or
-    polling to perform tasks in a non-blocking manner.
-
-Bert Belder, one of the libuv core developers has a small video explaining the
-architecture of libuv and its background. If you have no prior experience with
-either libuv or libev, it is a quick, useful watch.
-
-libuv's event loop is explained in more detail in the `documentation
-<https://docs.libuv.org/en/v1.x/design.html#the-i-o-loop>`_.

-
-Hello World
------------
-
-With the basics out of the way, let's write our first libuv program. It does
-nothing, except start a loop which will exit immediately.
-
-.. rubric:: helloworld/main.c
-.. literalinclude:: ../../code/helloworld/main.c
-    :language: c
-    :linenos:
-
-This program quits immediately because it has no events to process. A libuv
-event loop has to be told to watch out for events using the various API
-functions.
-
-Starting with libuv v1.0, users should allocate the memory for the loops before
-initializing it with ``uv_loop_init(uv_loop_t *)``. This allows you to plug in
-custom memory management. Remember to de-initialize the loop using
-``uv_loop_close(uv_loop_t *)`` and then delete the storage. The examples never
-close loops since the program quits after the loop ends and the system will
-reclaim memory. Production grade projects, especially long running systems
-programs, should take care to release correctly.
-
-Default loop
-++++++++++++
-
-A default loop is provided by libuv and can be accessed using
-``uv_default_loop()``. You should use this loop if you only want a single
-loop.
-
-.. rubric:: default-loop/main.c
-.. literalinclude:: ../../code/default-loop/main.c
-    :language: c
-    :linenos:
-
-.. note::
-
-    node.js uses the default loop as its main loop. If you are writing bindings
-    you should be aware of this.
-
-.. _libuv-error-handling:
-
-Error handling
---------------
-
-Initialization functions or synchronous functions which may fail return a negative number on error. Async functions that may fail will pass a status parameter to their callbacks. The error messages are defined as ``UV_E*`` `constants`_.
-
-.. _constants: https://docs.libuv.org/en/v1.x/errors.html#error-constants
-
-You can use the ``uv_strerror(int)`` and ``uv_err_name(int)`` functions
-to get a ``const char *`` describing the error or the error name respectively.
-
-I/O read callbacks (such as for files and sockets) are passed a parameter ``nread``. If ``nread`` is less than 0, there was an error (UV_EOF is the end of file error, which you may want to handle differently).
-
-Handles and Requests
---------------------
-
-libuv works by the user expressing interest in particular events. This is
-usually done by creating a **handle** to an I/O device, timer or process.
-Handles are opaque structs named as ``uv_TYPE_t`` where type signifies what the
-handle is used for.
-
-.. rubric:: libuv watchers
-.. code-block:: c
-
-    /* Handle types. */
-    typedef struct uv_loop_s uv_loop_t;
-    typedef struct uv_handle_s uv_handle_t;

-Handles represent long-lived objects. Async operations on such handles are
-identified using **requests**. A request is short-lived (usually used across
-only one callback) and usually indicates one I/O operation on a handle.
-Requests are used to preserve context between the initiation and the callback
-of individual actions. For example, an UDP socket is represented by
-a ``uv_udp_t``, while individual writes to the socket use a ``uv_udp_send_t``
-structure that is passed to the callback after the write is done.
-
-Handles are setup by a corresponding::
-
-    uv_TYPE_init(uv_loop_t *, uv_TYPE_t *)
-
-function.
-
-Callbacks are functions which are called by libuv whenever an event the watcher
-is interested in has taken place. Application specific logic will usually be
-implemented in the callback. For example, an IO watcher's callback will receive
-the data read from a file, a timer callback will be triggered on timeout and so
-on.
-
-Idling
-++++++
-
-Here is an example of using an idle handle. The callback is called once on
-every turn of the event loop. A use case for idle handles is discussed in
-:doc:`utilities`. Let us use an idle watcher to look at the watcher life cycle
-and see how ``uv_run()`` will now block because a watcher is present. The idle
-watcher is stopped when the count is reached and ``uv_run()`` exits since no
-event watchers are active.

-    :language: c
-    :emphasize-lines: 6,10,14-17
-
-Storing context
-+++++++++++++++
-
-In callback based programming style you'll often want to pass some 'context' --
-application specific information -- between the call site and the callback. All
-handles and requests have a ``void* data`` member which you can set to the
-context and cast back in the callback. This is a common pattern used throughout
-the C library ecosystem. In addition ``uv_loop_t`` also has a similar data
-member.

-Advanced event loops
-====================
-
-libuv provides considerable user control over event loops, and you can achieve
-interesting results by juggling multiple loops. You can also embed libuv's
-event loop into another event loop based library -- imagine a Qt based UI, and
-Qt's event loop driving a libuv backend which does intensive system level
-tasks.
-
-Stopping an event loop
-~~~~~~~~~~~~~~~~~~~~~~
-
-``uv_stop()`` can be used to stop an event loop. The earliest the loop will
-stop running is *on the next iteration*, possibly later. This means that events
-that are ready to be processed in this iteration of the loop will still be
-processed, so ``uv_stop()`` can't be used as a kill switch. When ``uv_stop()``
-is called, the loop **won't** block for i/o on this iteration. The semantics of
-these things can be a bit difficult to understand, so let's look at
-``uv_run()`` where all the control flow occurs.
-
-.. rubric:: src/unix/core.c - uv_run
-.. literalinclude:: ../../../src/unix/core.c
-    :language: c
-    :linenos:
-    :lines: 304-324
-    :emphasize-lines: 10,19,21
-
-``stop_flag`` is set by ``uv_stop()``. Now all libuv callbacks are invoked
-within the event loop, which is why invoking ``uv_stop()`` in them will still
-lead to this iteration of the loop occurring. First libuv updates timers, then
-runs pending timer, idle and prepare callbacks, and invokes any pending I/O
-callbacks. If you were to call ``uv_stop()`` in any of them, ``stop_flag``
-would be set. This causes ``uv_backend_timeout()`` to return ``0``, which is
-why the loop does not block on I/O. If on the other hand, you called
-``uv_stop()`` in one of the check handlers, I/O has already finished and is not
-affected.
-
-``uv_stop()`` is useful to shutdown a loop when a result has been computed or
-there is an error, without having to ensure that all handlers are stopped one
-by one.
-
-Here is a simple example that stops the loop and demonstrates how the current
-iteration of the loop still takes places.

-Filesystem
-==========
-
-Simple filesystem read/write is achieved using the ``uv_fs_*`` functions and the
-``uv_fs_t`` struct.
-
-.. note::
-
-    The libuv filesystem operations are different from :doc:`socket operations
-    <networking>`. Socket operations use the non-blocking operations provided
-    by the operating system. Filesystem operations use blocking functions
-    internally, but invoke these functions in a `thread pool`_ and notify
-    watchers registered with the event loop when application interaction is
-    required.
-
-.. _thread pool: https://docs.libuv.org/en/v1.x/threadpool.html#thread-pool-work-scheduling
-
-All filesystem functions have two forms - *synchronous* and *asynchronous*.
-
-The *synchronous* forms automatically get called (and **block**) if the
-callback is null. The return value of functions is a :ref:`libuv error code
-<libuv-error-handling>`. This is usually only useful for synchronous calls.
-The *asynchronous* form is called when a callback is passed and the return
-value is 0.
-
-Reading/Writing files
----------------------
-
-A file descriptor is obtained using
-
-.. code-block:: c
-
-    int uv_fs_open(uv_loop_t* loop, uv_fs_t* req, const char* path, int flags, int mode, uv_fs_cb cb)
-
-``flags`` and ``mode`` are standard
-`Unix flags <https://man7.org/linux/man-pages/man2/open.2.html>`_.
-libuv takes care of converting to the appropriate Windows flags.
-
-File descriptors are closed using
-
-.. code-block:: c
-
-    int uv_fs_close(uv_loop_t* loop, uv_fs_t* req, uv_file file, uv_fs_cb cb)
-
-
-Filesystem operation callbacks have the signature:
-
-.. code-block:: c
-
-    void callback(uv_fs_t* req);
-
-Let's see a simple implementation of ``cat``. We start with registering
-a callback for when the file is opened:
-
-.. rubric:: uvcat/main.c - opening a file
-.. literalinclude:: ../../code/uvcat/main.c
-    :language: c
-    :linenos:
-    :lines: 41-53
-    :emphasize-lines: 4, 6-7
-
-The ``result`` field of a ``uv_fs_t`` is the file descriptor in case of the
-``uv_fs_open`` callback. If the file is successfully opened, we start reading it.
-
-.. rubric:: uvcat/main.c - read callback
-.. literalinclude:: ../../code/uvcat/main.c
-    :language: c
-    :linenos:
-    :lines: 26-39
-    :emphasize-lines: 2,8,12
-
-In the case of a read call, you should pass an *initialized* buffer which will
-be filled with data before the read callback is triggered. The ``uv_fs_*``
-operations map almost directly to certain POSIX functions, so EOF is indicated
-in this case by ``result`` being 0. In the case of streams or pipes, the
-``UV_EOF`` constant would have been passed as a status instead.
-
-Here you see a common pattern when writing asynchronous programs. The
-``uv_fs_close()`` call is performed synchronously. *Usually tasks which are
-one-off, or are done as part of the startup or shutdown stage are performed
-synchronously, since we are interested in fast I/O when the program is going
-about its primary task and dealing with multiple I/O sources*. For solo tasks
-the performance difference usually is negligible and may lead to simpler code.
-
-Filesystem writing is similarly simple using ``uv_fs_write()``.  *Your callback
-will be triggered after the write is complete*.  In our case the callback
-simply drives the next read. Thus read and write proceed in lockstep via
-callbacks.
-
-.. rubric:: uvcat/main.c - write callback
-.. literalinclude:: ../../code/uvcat/main.c
-    :language: c
-    :linenos:
-    :lines: 17-24
-    :emphasize-lines: 6
-
-.. warning::
-
-    Due to the way filesystems and disk drives are configured for performance,
-    a write that 'succeeds' may not be committed to disk yet.
-
-We set the dominos rolling in ``main()``:
-
-.. rubric:: uvcat/main.c
-.. literalinclude:: ../../code/uvcat/main.c
-    :language: c
-    :linenos:
-    :lines: 55-
-    :emphasize-lines: 2
-
-.. warning::
-
-    The ``uv_fs_req_cleanup()`` function must always be called on filesystem
-    requests to free internal memory allocations in libuv.
-
-Filesystem operations
----------------------
-
-All the standard filesystem operations like ``unlink``, ``rmdir``, ``stat`` are
-supported asynchronously and have intuitive argument order. They follow the
-same patterns as the read/write/open calls, returning the result in the
-``uv_fs_t.result`` field. The full list:

-.. _buffers-and-streams:
-
-Buffers and Streams
--------------------
-
-The basic I/O handle in libuv is the stream (``uv_stream_t``). TCP sockets, UDP
-sockets, and pipes for file I/O and IPC are all treated as stream subclasses.
-
-Streams are initialized using custom functions for each subclass, then operated
-upon using
-
-.. code-block:: c
-
-    int uv_read_start(uv_stream_t*, uv_alloc_cb alloc_cb, uv_read_cb read_cb);
-    int uv_read_stop(uv_stream_t*);
-    int uv_write(uv_write_t* req, uv_stream_t* handle,
-                 const uv_buf_t bufs[], unsigned int nbufs, uv_write_cb cb);
-
-The stream based functions are simpler to use than the filesystem ones and
-libuv will automatically keep reading from a stream when ``uv_read_start()`` is
-called once, until ``uv_read_stop()`` is called.
-
-The discrete unit of data is the buffer -- ``uv_buf_t``. This is simply
-a collection of a pointer to bytes (``uv_buf_t.base``) and the length
-(``uv_buf_t.len``). The ``uv_buf_t`` is lightweight and passed around by value.
-What does require management is the actual bytes, which have to be allocated
-and freed by the application.
-
-.. ERROR::
-
-    **THIS PROGRAM DOES NOT ALWAYS WORK, NEED SOMETHING BETTER**
-
-To demonstrate streams we will need to use ``uv_pipe_t``. This allows streaming
-local files [#]_. Here is a simple tee utility using libuv.  Doing all operations
-asynchronously shows the power of evented I/O. The two writes won't block each
-other, but we have to be careful to copy over the buffer data to ensure we don't
-free a buffer until it has been written.
-
-The program is to be executed as::
-
-    ./uvtee <output_file>
-
-We start off opening pipes on the files we require. libuv pipes to a file are
-opened as bidirectional by default.
-
-.. rubric:: uvtee/main.c - read on pipes
-.. literalinclude:: ../../code/uvtee/main.c
-    :language: c
-    :linenos:
-    :lines: 62-80
-    :emphasize-lines: 4,5,15
-
-The third argument of ``uv_pipe_init()`` should be set to 1 for IPC using named
-pipes. This is covered in :doc:`processes`. The ``uv_pipe_open()`` call
-associates the pipe with the file descriptor, in this case ``0`` (standard
-input).
-
-We start monitoring ``stdin``. The ``alloc_buffer`` callback is invoked as new
-buffers are required to hold incoming data. ``read_stdin`` will be called with
-these buffers.
-
-.. rubric:: uvtee/main.c - reading buffers
-.. literalinclude:: ../../code/uvtee/main.c
-    :language: c
-    :linenos:
-    :lines: 19-22,44-60
-
-The standard ``malloc`` is sufficient here, but you can use any memory allocation
-scheme. For example, node.js uses its own slab allocator which associates
-buffers with V8 objects.
-
-The read callback ``nread`` parameter is less than 0 on any error. This error
-might be EOF, in which case we close all the streams, using the generic close
-function ``uv_close()`` which deals with the handle based on its internal type.
-Otherwise ``nread`` is a non-negative number and we can attempt to write that
-many bytes to the output streams. Finally remember that buffer allocation and
-deallocation is application responsibility, so we free the data.
-
-The allocation callback may return a buffer with length zero if it fails to
-allocate memory. In this case, the read callback is invoked with error
-UV_ENOBUFS. libuv will continue to attempt to read the stream though, so you
-must explicitly call ``uv_close()`` if you want to stop when allocation fails.
-
-The read callback may be called with ``nread = 0``, indicating that at this
-point there is nothing to be read. Most applications will just ignore this.
-
-.. rubric:: uvtee/main.c - Write to pipe
-.. literalinclude:: ../../code/uvtee/main.c
-    :language: c
-    :linenos:
-    :lines: 9-13,23-42
-
-``write_data()`` makes a copy of the buffer obtained from read. This buffer
-does not get passed through to the write callback trigged on write completion. To
-get around this we wrap a write request and a buffer in ``write_req_t`` and
-unwrap it in the callbacks. We make a copy so we can free the two buffers from
-the two calls to ``write_data`` independently of each other. While acceptable
-for a demo program like this, you'll probably want smarter memory management,
-like reference counted buffers or a pool of buffers in any major application.
-
-.. WARNING::
-
-    If your program is meant to be used with other programs it may knowingly or
-    unknowingly be writing to a pipe. This makes it susceptible to `aborting on
-    receiving a SIGPIPE`_. It is a good idea to insert::
-
-        signal(SIGPIPE, SIG_IGN)
-
-    in the initialization stages of your application.

-
-File change events
-------------------
-
-All modern operating systems provide APIs to put watches on individual files or
-directories and be informed when the files are modified. libuv wraps common
-file change notification libraries [#fsnotify]_. This is one of the more
-inconsistent parts of libuv. File change notification systems are themselves
-extremely varied across platforms so getting everything working everywhere is
-difficult. To demonstrate, I'm going to build a simple utility which runs
-a command whenever any of the watched files change::
-
-    ./onchange <command> <file1> [file2] ...
-
-.. note::
-
-    Currently this example only works on OSX and Windows.
-    Refer to the `notes of uv_fs_event_start`_ function.
-
-.. _notes of uv_fs_event_start: https://docs.libuv.org/en/v1.x/fs_event.html#c.uv_fs_event_start
-
-The file change notification is started using ``uv_fs_event_init()``:
-
-.. rubric:: onchange/main.c - The setup
-.. literalinclude:: ../../code/onchange/main.c
-    :language: c
-    :linenos:
-    :lines: 26-
-    :emphasize-lines: 15
-
-The third argument is the actual file or directory to monitor. The last
-argument, ``flags``, can be:
-
-.. code-block:: c
-
-    /*
-     * Flags to be passed to uv_fs_event_start().
-     */
-    enum uv_fs_event_flags {
-        UV_FS_EVENT_WATCH_ENTRY = 1,
-        UV_FS_EVENT_STAT = 2,
-        UV_FS_EVENT_RECURSIVE = 4
-    };
-
-``UV_FS_EVENT_WATCH_ENTRY`` and ``UV_FS_EVENT_STAT`` don't do anything (yet).
-``UV_FS_EVENT_RECURSIVE`` will start watching subdirectories as well on
-supported platforms.
-
-The callback will receive the following arguments:
-
-  #. ``uv_fs_event_t *handle`` - The handle. The ``path`` field of the handle
-     is the file on which the watch was set.
-  #. ``const char *filename`` - If a directory is being monitored, this is the
-     file which was changed. Only non-``null`` on Linux and Windows. May be ``null``
-     even on those platforms.
-  #. ``int events`` - one of ``UV_RENAME`` or ``UV_CHANGE``, or a bitwise OR of
-     both.
-  #. ``int status`` - If ``status < 0``, there is an :ref:`libuv error<libuv-error-handling>`.
-
-In our example we simply print the arguments and run the command using
-``system()``.

-a high performance evented I/O library which offers the same API on Windows and Unix.
-
-It is meant to cover the main areas of libuv, but is not a comprehensive
-reference discussing every function and data structure. The `official libuv
-documentation`_ may be consulted for full details.
-
-.. _official libuv documentation: https://docs.libuv.org/en/v1.x/
-
-This book is still a work in progress, so sections may be incomplete, but
-I hope you will enjoy it as it grows.
-
-Who this book is for
---------------------
-
-If you are reading this book, you are either:
-
-1) a systems programmer, creating low-level programs such as daemons or network
-   services and clients. You have found that the event loop approach is well
-   suited for your application and decided to use libuv.
-
-2) a node.js module writer, who wants to wrap platform APIs
-   written in C or C++ with a set of (a)synchronous APIs that are exposed to
-   JavaScript. You will use libuv purely in the context of node.js. For
-   this you will require some other resources as the book does not cover parts
-   specific to v8/node.js.
-
-This book assumes that you are comfortable with the C programming language.
-
-Background
-----------
-
-The node.js_ project began in 2009 as a JavaScript environment decoupled
-from the browser. Using Google's V8_ and Marc Lehmann's libev_, node.js
-combined a model of I/O -- evented -- with a language that was well suited to
-the style of programming; due to the way it had been shaped by browsers. As
-node.js grew in popularity, it was important to make it work on Windows, but
-libev ran only on Unix. The Windows equivalent of kernel event notification
-mechanisms like kqueue or (e)poll is IOCP. libuv was an abstraction around libev
-or IOCP depending on the platform, providing users an API based on libev.
-In the node-v0.9.0 version of libuv `libev was removed`_.
-
-Since then libuv has continued to mature and become a high quality standalone
-library for system programming. Users outside of node.js include Mozilla's
-Rust_ programming language, and a variety_ of language bindings.
-
-This book and the code is based on libuv version `v1.42.0`_.
-
-Code
-----
-
-All the example code and the source of the book is included as part of
-the libuv_ project on GitHub.
-Clone or Download libuv_, then build it::
-
-    sh autogen.sh
-    ./configure
-    make
-
-There is no need to ``make install``. To build the examples run ``make`` in the
-``docs/code/`` directory.

-Networking
-==========
-
-Networking in libuv is not much different from directly using the BSD socket
-interface, some things are easier, all are non-blocking, but the concepts stay
-the same. In addition libuv offers utility functions to abstract the annoying,
-repetitive and low-level tasks like setting up sockets using the BSD socket
-structures, DNS lookup, and tweaking various socket parameters.
-
-The ``uv_tcp_t`` and ``uv_udp_t`` structures are used for network I/O.
-
-.. NOTE::
-
-  The code samples in this chapter exist to show certain libuv APIs. They are
-  not examples of good quality code. They leak memory and don't always close
-  connections properly.
-
-TCP
----
-
-TCP is a connection oriented, stream protocol and is therefore based on the
-libuv streams infrastructure.
-
-Server
-++++++
-
-Server sockets proceed by:
-
-1. ``uv_tcp_init`` the TCP handle.
-2. ``uv_tcp_bind`` it.
-3. Call ``uv_listen`` on the handle to have a callback invoked whenever a new
-   connection is established by a client.
-4. Use ``uv_accept`` to accept the connection.
-5. Use :ref:`stream operations <buffers-and-streams>` to communicate with the
-   client.
-
-Here is a simple echo server
-
-.. rubric:: tcp-echo-server/main.c - The listen socket
-.. literalinclude:: ../../code/tcp-echo-server/main.c
-    :language: c
-    :linenos:
-    :lines: 68-
-    :emphasize-lines: 4-5,7-10
-
-You can see the utility function ``uv_ip4_addr`` being used to convert from
-a human readable IP address, port pair to the sockaddr_in structure required by
-the BSD socket APIs. The reverse can be obtained using ``uv_ip4_name``.
-
-.. NOTE::
-
-    There are ``uv_ip6_*`` analogues for the ip4 functions.
-
-Most of the setup functions are synchronous since they are CPU-bound.
-``uv_listen`` is where we return to libuv's callback style. The second
-arguments is the backlog queue -- the maximum length of queued connections.
-
-When a connection is initiated by clients, the callback is required to set up
-a handle for the client socket and associate the handle using ``uv_accept``.
-In this case we also establish interest in reading from this stream.
-
-.. rubric:: tcp-echo-server/main.c - Accepting the client
-.. literalinclude:: ../../code/tcp-echo-server/main.c
-    :language: c
-    :linenos:
-    :lines: 51-66
-    :emphasize-lines: 9-10
-
-The remaining set of functions is very similar to the streams example and can
-be found in the code. Just remember to call ``uv_close`` when the socket isn't
-required. This can be done even in the ``uv_listen`` callback if you are not
-interested in accepting the connection.
-
-Client
-++++++
-
-Where you do bind/listen/accept on the server, on the client side it's simply
-a matter of calling ``uv_tcp_connect``. The same ``uv_connect_cb`` style
-callback of ``uv_listen`` is used by ``uv_tcp_connect``. Try::
-
-    uv_tcp_t* socket = (uv_tcp_t*)malloc(sizeof(uv_tcp_t));
-    uv_tcp_init(loop, socket);
-
-    uv_connect_t* connect = (uv_connect_t*)malloc(sizeof(uv_connect_t));
-
-    struct sockaddr_in dest;
-    uv_ip4_addr("127.0.0.1", 80, &dest);
-
-    uv_tcp_connect(connect, socket, (const struct sockaddr*)&dest, on_connect);
-
-where ``on_connect`` will be called after the connection is established. The
-callback receives the ``uv_connect_t`` struct, which has a member ``.handle``
-pointing to the socket.
-
-UDP
----
-
-The `User Datagram Protocol`_ offers connectionless, unreliable network
-communication. Hence libuv doesn't offer a stream. Instead libuv provides
-non-blocking UDP support via the `uv_udp_t` handle (for receiving) and
-`uv_udp_send_t` request (for sending) and related functions. That said, the
-actual API for reading/writing is very similar to normal stream reads. To look
-at how UDP can be used, the example shows the first stage of obtaining an IP
-address from a `DHCP`_ server -- DHCP Discover.
-
-.. note::
-
-    You will have to run `udp-dhcp` as **root** since it uses well known port
-    numbers below 1024.
-
-.. rubric:: udp-dhcp/main.c - Setup and send UDP packets
-.. literalinclude:: ../../code/udp-dhcp/main.c
-    :language: c
-    :linenos:
-    :lines: 7-11,104-
-    :emphasize-lines: 8,10-11,17-18,21
-
-.. note::
-
-    The IP address ``0.0.0.0`` is used to bind to all interfaces. The IP
-    address ``255.255.255.255`` is a broadcast address meaning that packets
-    will be sent to all interfaces on the subnet.  port ``0`` means that the OS
-    randomly assigns a port.
-
-First we setup the receiving socket to bind on all interfaces on port 68 (DHCP
-client) and start a read on it. This will read back responses from any DHCP
-server that replies. We use the UV_UDP_REUSEADDR flag to play nice with any
-other system DHCP clients that are running on this computer on the same port.
-Then we setup a similar send socket and use ``uv_udp_send`` to send
-a *broadcast message* on port 67 (DHCP server).
-
-It is **necessary** to set the broadcast flag, otherwise you will get an
-``EACCES`` error [#]_. The exact message being sent is not relevant to this
-book and you can study the code if you are interested. As usual the read and
-write callbacks will receive a status code of < 0 if something went wrong.
-
-Since UDP sockets are not connected to a particular peer, the read callback
-receives an extra parameter about the sender of the packet.
-
-``nread`` may be zero if there is no more data to be read. If ``addr`` is NULL,
-it indicates there is nothing to read (the callback shouldn't do anything), if
-not NULL, it indicates that an empty datagram was received from the host at
-``addr``. The ``flags`` parameter may be ``UV_UDP_PARTIAL`` if the buffer
-provided by your allocator was not large enough to hold the data. *In this case
-the OS will discard the data that could not fit* (That's UDP for you!).

-    :emphasize-lines: 1,23
-
-UDP Options
-+++++++++++
-
-Time-to-live
-~~~~~~~~~~~~
-
-The TTL of packets sent on the socket can be changed using ``uv_udp_set_ttl``.
-
-IPv6 stack only
-~~~~~~~~~~~~~~~
-
-IPv6 sockets can be used for both IPv4 and IPv6 communication. If you want to
-restrict the socket to IPv6 only, pass the ``UV_UDP_IPV6ONLY`` flag to
-``uv_udp_bind``.
-
-Multicast
-~~~~~~~~~
-
-A socket can (un)subscribe to a multicast group using:
-
-.. code::block:: c
-
-    int uv_udp_set_membership(uv_udp_t* handle, const char* multicast_addr, const char* interface_addr, uv_membership membership);
-
-where ``membership`` is ``UV_JOIN_GROUP`` or ``UV_LEAVE_GROUP``.
-
-The concepts of multicasting are nicely explained in `this guide`_.
-
-.. _this guide: https://www.tldp.org/HOWTO/Multicast-HOWTO-2.html
-
-Local loopback of multicast packets is enabled by default [#]_, use
-``uv_udp_set_multicast_loop`` to switch it off.
-
-The packet time-to-live for multicast packets can be changed using
-``uv_udp_set_multicast_ttl``.
-
-Querying DNS
-------------
-
-libuv provides asynchronous DNS resolution. For this it provides its own
-``getaddrinfo`` replacement [#]_. In the callback you can
-perform normal socket operations on the retrieved addresses. Let's connect to
-Libera.chat to see an example of DNS resolution.
-
-.. rubric:: dns/main.c
-.. literalinclude:: ../../code/dns/main.c
-    :language: c
-    :linenos:
-    :lines: 61-
-    :emphasize-lines: 12
-
-If ``uv_getaddrinfo`` returns non-zero, something went wrong in the setup and
-your callback won't be invoked at all. All arguments can be freed immediately
-after ``uv_getaddrinfo`` returns. The `hostname`, `servname` and `hints`
-structures are documented in `the getaddrinfo man page <getaddrinfo_>`_. The
-callback can be ``NULL`` in which case the function will run synchronously.
-
-In the resolver callback, you can pick any IP from the linked list of ``struct
-addrinfo(s)``. This also demonstrates ``uv_tcp_connect``. It is necessary to
-call ``uv_freeaddrinfo`` in the callback.
-
-.. rubric:: dns/main.c
-.. literalinclude:: ../../code/dns/main.c
-    :language: c
-    :linenos:
-    :lines: 42-60
-    :emphasize-lines: 8,16
-
-libuv also provides the inverse `uv_getnameinfo`_.
-
-.. _uv_getnameinfo: http://docs.libuv.org/en/v1.x/dns.html#c.uv_getnameinfo
-
-Network interfaces
-------------------
-
-Information about the system's network interfaces can be obtained through libuv
-using ``uv_interface_addresses``. This simple program just prints out all the
-interface details so you get an idea of the fields that are available. This is
-useful to allow your service to bind to IP addresses when it starts.
-
-.. rubric:: interfaces/main.c
-.. literalinclude:: ../../code/interfaces/main.c
-    :language: c
-    :linenos:
-    :emphasize-lines: 9,17
-
-``is_internal`` is true for loopback interfaces. Note that if a physical
-interface has multiple IPv4/IPv6 addresses, the name will be reported multiple
-times, with each address being reported once.

-Processes
-=========
-
-libuv offers considerable child process management, abstracting the platform
-differences and allowing communication with the child process using streams or
-named pipes.
-
-A common idiom in Unix is for every process to do one thing and do it well. In
-such a case, a process often uses multiple child processes to achieve tasks
-(similar to using pipes in shells). A multi-process model with messages
-may also be easier to reason about compared to one with threads and shared
-memory.
-
-A common refrain against event-based programs is that they cannot take
-advantage of multiple cores in modern computers. In a multi-threaded program
-the kernel can perform scheduling and assign different threads to different
-cores, improving performance. But an event loop has only one thread.  The
-workaround can be to launch multiple processes instead, with each process
-running an event loop, and each process getting assigned to a separate CPU
-core.
-
-Spawning child processes
-------------------------
-
-The simplest case is when you simply want to launch a process and know when it
-exits. This is achieved using ``uv_spawn``.
-
-.. rubric:: spawn/main.c
-.. literalinclude:: ../../code/spawn/main.c
-    :language: c
-    :linenos:
-    :lines: 6-8,15-
-    :emphasize-lines: 11,13-17
-
-.. NOTE::
-
-    ``options`` is implicitly initialized with zeros since it is a global
-    variable.  If you change ``options`` to a local variable, remember to
-    initialize it to null out all unused fields::
-
-        uv_process_options_t options = {0};
-
-The ``uv_process_t`` struct only acts as the handle, all options are set via
-``uv_process_options_t``. To simply launch a process, you need to set only the
-``file`` and ``args`` fields. ``file`` is the program to execute. Since
-``uv_spawn`` uses :man:`execvp(3)` internally, there is no need to supply the full
-path. Finally as per underlying conventions, **the arguments array has to be
-one larger than the number of arguments, with the last element being NULL**.
-
-After the call to ``uv_spawn``, ``uv_process_t.pid`` will contain the process
-ID of the child process.
-
-The exit callback will be invoked with the *exit status* and the type of *signal*
-which caused the exit.
-
-Note that it is important **not** to call ``uv_close`` before the exit callback.
-
-.. rubric:: spawn/main.c
-.. literalinclude:: ../../code/spawn/main.c
-    :language: c
-    :linenos:
-    :lines: 9-12
-    :emphasize-lines: 3
-
-It is **required** to close the process watcher after the process exits.
-
-Changing process parameters
----------------------------
-
-Before the child process is launched you can control the execution environment
-using fields in ``uv_process_options_t``.
-
-Change execution directory
-++++++++++++++++++++++++++
-
-Set ``uv_process_options_t.cwd`` to the corresponding directory.
-
-Set environment variables
-+++++++++++++++++++++++++
-
-``uv_process_options_t.env`` is a null-terminated array of strings, each of the
-form ``VAR=VALUE`` used to set up the environment variables for the process. Set
-this to ``NULL`` to inherit the environment from the parent (this) process.
-
-Option flags
-++++++++++++
-
-Setting ``uv_process_options_t.flags`` to a bitwise OR of the following flags,
-modifies the child process behaviour:
-
-* ``UV_PROCESS_SETUID`` - sets the child's execution user ID to ``uv_process_options_t.uid``.
-* ``UV_PROCESS_SETGID`` - sets the child's execution group ID to ``uv_process_options_t.gid``.
-
-Changing the UID/GID is only supported on Unix, ``uv_spawn`` will fail on
-Windows with ``UV_ENOTSUP``.
-
-* ``UV_PROCESS_WINDOWS_VERBATIM_ARGUMENTS`` - No quoting or escaping of
-  ``uv_process_options_t.args`` is done on Windows. Ignored on Unix.
-* ``UV_PROCESS_DETACHED`` - Starts the child process in a new session, which
-  will keep running after the parent process exits. See example below.
-
-Detaching processes
--------------------
-
-Passing the flag ``UV_PROCESS_DETACHED`` can be used to launch daemons, or
-child processes which are independent of the parent so that the parent exiting
-does not affect it.
-
-.. rubric:: detach/main.c
-.. literalinclude:: ../../code/detach/main.c
-    :language: c
-    :linenos:
-    :lines: 9-30
-    :emphasize-lines: 12,19
-
-Just remember that the handle is still monitoring the child, so your program
-won't exit. Use ``uv_unref()`` if you want to be more *fire-and-forget*.
-
-Sending signals to processes
-----------------------------
-
-libuv wraps the standard ``kill(2)`` system call on Unix and implements one
-with similar semantics on Windows, with *one caveat*: all of ``SIGTERM``,
-``SIGINT`` and ``SIGKILL``, lead to termination of the process. The signature
-of ``uv_kill`` is::
-
-    uv_err_t uv_kill(int pid, int signum);
-
-For processes started using libuv, you may use ``uv_process_kill`` instead,
-which accepts the ``uv_process_t`` watcher as the first argument, rather than
-the pid. In this case, **remember to call** ``uv_close`` on the watcher _after_
-the exit callback has been called.
-
-Signals
--------
-
-libuv provides wrappers around Unix signals with `some Windows support
-<http://docs.libuv.org/en/v1.x/signal.html#signal>`_ as well.
-
-Use ``uv_signal_init()`` to initialize
-a handle and associate it with a loop. To listen for particular signals on
-that handler, use ``uv_signal_start()`` with the handler function. Each handler
-can only be associated with one signal number, with subsequent calls to
-``uv_signal_start()`` overwriting earlier associations. Use ``uv_signal_stop()`` to
-stop watching. Here is a small example demonstrating the various possibilities:
-
-.. rubric:: signal/main.c
-.. literalinclude:: ../../code/signal/main.c
-    :language: c
-    :linenos:
-    :emphasize-lines: 17-18,27-28
-
-.. NOTE::
-
-    ``uv_run(loop, UV_RUN_NOWAIT)`` is similar to ``uv_run(loop, UV_RUN_ONCE)``
-    in that it will process only one event. UV_RUN_ONCE blocks if there are no
-    pending events, while UV_RUN_NOWAIT will return immediately. We use NOWAIT
-    so that one of the loops isn't starved because the other one has no pending
-    activity.
-
-Send ``SIGUSR1`` to the process, and you'll find the handler being invoked
-4 times, one for each ``uv_signal_t``. The handler just stops each handle,
-so that the program exits. This sort of dispatch to all handlers is very
-useful. A server using multiple event loops could ensure that all data was
-safely saved before termination, simply by every loop adding a watcher for
-``SIGINT``.
-
-Child Process I/O
------------------
-
-A normal, newly spawned process has its own set of file descriptors, with 0,
-1 and 2 being ``stdin``, ``stdout`` and ``stderr`` respectively. Sometimes you
-may want to share file descriptors with the child. For example, perhaps your
-applications launches a sub-command and you want any errors to go in the log
-file, but ignore ``stdout``. For this you'd like to have ``stderr`` of the
-child be the same as the stderr of the parent. In this case, libuv supports
-*inheriting* file descriptors. In this sample, we invoke the test program,
-which is:
-
-.. rubric:: proc-streams/test.c
-.. literalinclude:: ../../code/proc-streams/test.c
-    :language: c
-
-The actual program ``proc-streams`` runs this while sharing only ``stderr``.
-The file descriptors of the child process are set using the ``stdio`` field in
-``uv_process_options_t``. First set the ``stdio_count`` field to the number of
-file descriptors being set. ``uv_process_options_t.stdio`` is an array of
-``uv_stdio_container_t``, which is:
-
-.. code-block:: c
-
-    typedef struct uv_stdio_container_s {
-        uv_stdio_flags flags;
-
-        union {
-            uv_stream_t* stream;
-            int fd;
-        } data;
-    } uv_stdio_container_t;
-
-where flags can have several values. Use ``UV_IGNORE`` if it isn't going to be
-used. If the first three ``stdio`` fields are marked as ``UV_IGNORE`` they'll
-redirect to ``/dev/null``.
-
-Since we want to pass on an existing descriptor, we'll use ``UV_INHERIT_FD``.
-Then we set the ``fd`` to ``stderr``.
-
-.. rubric:: proc-streams/main.c
-.. literalinclude:: ../../code/proc-streams/main.c
-    :language: c
-    :linenos:
-    :lines: 15-17,27-
-    :emphasize-lines: 6,10,11,12
-
-If you run ``proc-stream`` you'll see that only the line "This is stderr" will
-be displayed. Try marking ``stdout`` as being inherited and see the output.
-
-It is dead simple to apply this redirection to streams.  By setting ``flags``
-to ``UV_INHERIT_STREAM`` and setting ``data.stream`` to the stream in the
-parent process, the child process can treat that stream as standard I/O. This
-can be used to implement something like CGI_.
-
-.. _CGI: https://en.wikipedia.org/wiki/Common_Gateway_Interface
-
-A sample CGI script/executable is:
-
-.. rubric:: cgi/tick.c
-.. literalinclude:: ../../code/cgi/tick.c
-    :language: c
-
-The CGI server combines the concepts from this chapter and :doc:`networking` so
-that every client is sent ten ticks after which that connection is closed.
-
-.. rubric:: cgi/main.c
-.. literalinclude:: ../../code/cgi/main.c
-    :language: c
-    :linenos:
-    :lines: 49-63
-    :emphasize-lines: 10
-
-Here we simply accept the TCP connection and pass on the socket (*stream*) to
-``invoke_cgi_script``.
-
-.. rubric:: cgi/main.c
-.. literalinclude:: ../../code/cgi/main.c
-    :language: c
-    :linenos:
-    :lines: 16, 25-45
-    :emphasize-lines: 8-9,18,20
-
-The ``stdout`` of the CGI script is set to the socket so that whatever our tick
-script prints, gets sent to the client. By using processes, we can offload the
-read/write buffering to the operating system, so in terms of convenience this
-is great. Just be warned that creating processes is a costly task.
-
-.. _pipes:
-
-Parent-child IPC
-----------------
-
-A parent and child can have one or two way communication over a pipe created by
-settings ``uv_stdio_container_t.flags`` to a bit-wise combination of
-``UV_CREATE_PIPE`` and ``UV_READABLE_PIPE`` or ``UV_WRITABLE_PIPE``. The
-read/write flag is from the perspective of the child process.  In this case,
-the ``uv_stream_t* stream`` field must be set to point to an initialized,
-unopened ``uv_pipe_t`` instance.
-
-New stdio Pipes
-+++++++++++++++
-
-The ``uv_pipe_t`` structure represents more than just `pipe(7)`_ (or ``|``),
-but supports any streaming file-like objects. On Windows, the only object of
-that description is the `Named Pipe`_.  On Unix, this could be any of `Unix
-Domain Socket`_, or derived from `mkfifo(1)`_, or it could actually be a
-`pipe(7)`_.  When ``uv_spawn`` initializes a ``uv_pipe_t`` due to the
-`UV_CREATE_PIPE` flag, it opts for creating a `socketpair(2)`_.
-
-This is intended for the purpose of allowing multiple libuv processes to
-communicate with IPC. This is discussed below.

-Arbitrary process IPC
-+++++++++++++++++++++
-
-Since domain sockets [#]_ can have a well known name and a location in the
-file-system they can be used for IPC between unrelated processes. The D-BUS_
-system used by open source desktop environments uses domain sockets for event
-notification. Various applications can then react when a contact comes online
-or new hardware is detected. The MySQL server also runs a domain socket on
-which clients can interact with it.
-
-.. _D-BUS: https://www.freedesktop.org/wiki/Software/dbus
-
-When using domain sockets, a client-server pattern is usually followed with the
-creator/owner of the socket acting as the server. After the initial setup,
-messaging is no different from TCP, so we'll re-use the echo server example.
-
-.. rubric:: pipe-echo-server/main.c
-.. literalinclude:: ../../code/pipe-echo-server/main.c
-    :language: c
-    :linenos:
-    :lines: 70-
-    :emphasize-lines: 5,10,14
-
-We name the socket ``echo.sock`` which means it will be created in the local
-directory. This socket now behaves no different from TCP sockets as far as
-the stream API is concerned. You can test this server using `socat`_::
-
-    $ socat - /path/to/socket
-
-A client which wants to connect to a domain socket will use::
-
-    void uv_pipe_connect(uv_connect_t *req, uv_pipe_t *handle, const char *name, uv_connect_cb cb);
-
-where ``name`` will be ``echo.sock`` or similar. On Unix systems, ``name`` must
-point to a valid file (e.g. ``/tmp/echo.sock``). On Windows, ``name`` follows a
-``\\?\pipe\echo.sock`` format.
-
-.. _socat: http://www.dest-unreach.org/socat/
-
-Sending file descriptors over pipes
-+++++++++++++++++++++++++++++++++++
-
-The cool thing about domain sockets is that file descriptors can be exchanged
-between processes by sending them over a domain socket. This allows processes
-to hand off their I/O to other processes. Applications include load-balancing
-servers, worker processes and other ways to make optimum use of CPU. libuv only
-supports sending **TCP sockets or other pipes** over pipes for now.
-
-To demonstrate, we will look at a echo server implementation that hands of
-clients to worker processes in a round-robin fashion. This program is a bit
-involved, and while only snippets are included in the book, it is recommended
-to read the full code to really understand it.
-
-The worker process is quite simple, since the file-descriptor is handed over to
-it by the master.
-
-.. rubric:: multi-echo-server/worker.c
-.. literalinclude:: ../../code/multi-echo-server/worker.c
-    :language: c
-    :linenos:
-    :lines: 7-9,81-
-    :emphasize-lines: 6-8
-
-``queue`` is the pipe connected to the master process on the other end, along
-which new file descriptors get sent. It is important to set the ``ipc``
-argument of ``uv_pipe_init`` to 1 to indicate this pipe will be used for
-inter-process communication! Since the master will write the file handle to the
-standard input of the worker, we connect the pipe to ``stdin`` using
-``uv_pipe_open``.
-
-.. rubric:: multi-echo-server/worker.c
-.. literalinclude:: ../../code/multi-echo-server/worker.c
-    :language: c
-    :linenos:
-    :lines: 51-79
-    :emphasize-lines: 10,15,20
-
-First we call ``uv_pipe_pending_count()`` to ensure that a handle is available
-to read out. If your program could deal with different types of handles,
-``uv_pipe_pending_type()`` can be used to determine the type.
-Although ``accept`` seems odd in this code, it actually makes sense. What
-``accept`` traditionally does is get a file descriptor (the client) from
-another file descriptor (The listening socket). Which is exactly what we do
-here. Fetch the file descriptor (``client``) from ``queue``. From this point
-the worker does standard echo server stuff.
-
-Turning now to the master, let's take a look at how the workers are launched to
-allow load balancing.
-
-.. rubric:: multi-echo-server/main.c
-.. literalinclude:: ../../code/multi-echo-server/main.c
-    :language: c
-    :linenos:
-    :lines: 9-13
-
-The ``child_worker`` structure wraps the process, and the pipe between the
-master and the individual process.
-
-.. rubric:: multi-echo-server/main.c
-.. literalinclude:: ../../code/multi-echo-server/main.c
-    :language: c
-    :linenos:
-    :lines: 51,61-95
-    :emphasize-lines: 17,20-21
-
-In setting up the workers, we use the nifty libuv function ``uv_cpu_info`` to
-get the number of CPUs so we can launch an equal number of workers. Again it is
-important to initialize the pipe acting as the IPC channel with the third
-argument as 1. We then indicate that the child process' ``stdin`` is to be
-a readable pipe (from the point of view of the child). Everything is
-straightforward till here. The workers are launched and waiting for file
-descriptors to be written to their standard input.
-
-It is in ``on_new_connection`` (the TCP infrastructure is initialized in
-``main()``), that we accept the client socket and pass it along to the next
-worker in the round-robin.
-
-.. rubric:: multi-echo-server/main.c
-.. literalinclude:: ../../code/multi-echo-server/main.c
-    :language: c
-    :linenos:
-    :lines: 31-49
-    :emphasize-lines: 9,12-13
-
-The ``uv_write2`` call handles all the abstraction and it is simply a matter of
-passing in the handle (``client``) as the right argument. With this our
-multi-process echo server is operational.
-
-Thanks to Kyle for `pointing out`_ that ``uv_write2()`` requires a non-empty
-buffer even when sending handles.

-Threads
-=======
-
-Wait a minute? Why are we on threads? Aren't event loops supposed to be **the
-way** to do *web-scale programming*? Well... no. Threads are still the medium in
-which processors do their jobs. Threads are therefore mighty useful sometimes, even
-though you might have to wade through various synchronization primitives.
-
-Threads are used internally to fake the asynchronous nature of all of the system
-calls. libuv also uses threads to allow you, the application, to perform a task
-asynchronously that is actually blocking, by spawning a thread and collecting
-the result when it is done.
-
-Today there are two predominant thread libraries: the Windows threads
-implementation and POSIX's :man:`pthreads(7)`. libuv's thread API is analogous to
-the pthreads API and often has similar semantics.
-
-A notable aspect of libuv's thread facilities is that it is a self contained
-section within libuv. Whereas other features intimately depend on the event
-loop and callback principles, threads are complete agnostic, they block as
-required, signal errors directly via return values, and, as shown in the
-:ref:`first example <thread-create-example>`, don't even require a running
-event loop.
-
-libuv's thread API is also very limited since the semantics and syntax of
-threads are different on all platforms, with different levels of completeness.
-
-This chapter makes the following assumption: **There is only one event loop,
-running in one thread (the main thread)**. No other thread interacts
-with the event loop (except using ``uv_async_send``).
-
-Core thread operations
-----------------------
-
-There isn't much here, you just start a thread using ``uv_thread_create()`` and
-wait for it to close using ``uv_thread_join()``.
-
-.. _thread-create-example:
-
-.. rubric:: thread-create/main.c
-.. literalinclude:: ../../code/thread-create/main.c
-    :language: c
-    :linenos:
-    :lines: 26-36
-    :emphasize-lines: 3-7
-
-.. tip::
-
-    ``uv_thread_t`` is just an alias for ``pthread_t`` on Unix, but this is an
-    implementation detail, avoid depending on it to always be true.
-
-The second parameter is the function which will serve as the entry point for
-the thread, the last parameter is a ``void *`` argument which can be used to pass
-custom parameters to the thread. The function ``hare`` will now run in a separate
-thread, scheduled pre-emptively by the operating system:
-
-.. rubric:: thread-create/main.c
-.. literalinclude:: ../../code/thread-create/main.c
-    :language: c
-    :linenos:
-    :lines: 6-14
-    :emphasize-lines: 2
-
-Unlike ``pthread_join()`` which allows the target thread to pass back a value to
-the calling thread using a second parameter, ``uv_thread_join()`` does not. To
-send values use :ref:`inter-thread-communication`.
-
-Synchronization Primitives
---------------------------
-
-This section is purposely spartan. This book is not about threads, so I only
-catalogue any surprises in the libuv APIs here. For the rest you can look at
-the :man:`pthreads(7)` man pages.
-
-Mutexes
-~~~~~~~
-
-The mutex functions are a **direct** map to the pthread equivalents.
-
-.. rubric:: libuv mutex functions
-.. code-block:: c
-
-    int uv_mutex_init(uv_mutex_t* handle);
-    int uv_mutex_init_recursive(uv_mutex_t* handle);
-    void uv_mutex_destroy(uv_mutex_t* handle);
-    void uv_mutex_lock(uv_mutex_t* handle);
-    int uv_mutex_trylock(uv_mutex_t* handle);
-    void uv_mutex_unlock(uv_mutex_t* handle);
-
-The ``uv_mutex_init()``, ``uv_mutex_init_recursive()`` and ``uv_mutex_trylock()``
-functions will return 0 on success, and an error code otherwise.
-
-If `libuv` has been compiled with debugging enabled, ``uv_mutex_destroy()``,
-``uv_mutex_lock()`` and ``uv_mutex_unlock()`` will ``abort()`` on error.
-Similarly ``uv_mutex_trylock()`` will abort if the error is anything *other
-than* ``EAGAIN`` or ``EBUSY``.
-
-Recursive mutexes are supported, but you should not rely on them. Also, they
-should not be used with ``uv_cond_t`` variables.
-
-The default BSD mutex implementation will raise an error if a thread which has
-locked a mutex attempts to lock it again. For example, a construct like::
-
-    uv_mutex_init(a_mutex);
-    uv_mutex_lock(a_mutex);
-    uv_thread_create(thread_id, entry, (void *)a_mutex);
-    uv_mutex_lock(a_mutex);
-    // more things here
-
-can be used to wait until another thread initializes some stuff and then
-unlocks ``a_mutex`` but will lead to your program crashing if in debug mode, or
-return an error in the second call to ``uv_mutex_lock()``.
-
-.. note::
-
-    Mutexes on Windows are always recursive.
-
-Locks
-~~~~~
-
-Read-write locks are a more granular access mechanism. Two readers can access
-shared memory at the same time. A writer may not acquire the lock when it is
-held by a reader. A reader or writer may not acquire a lock when a writer is
-holding it. Read-write locks are frequently used in databases. Here is a toy
-example.
-
-.. rubric:: locks/main.c - simple rwlocks
-.. literalinclude:: ../../code/locks/main.c
-    :language: c
-    :linenos:
-    :emphasize-lines: 13,16,27,31,42,55
-
-Run this and observe how the readers will sometimes overlap. In case of
-multiple writers, schedulers will usually give them higher priority, so if you
-add two writers, you'll see that both writers tend to finish first before the
-readers get a chance again.
-
-We also use barriers in the above example so that the main thread can wait for
-all readers and writers to indicate they have ended.
-
-Others
-~~~~~~
-
-libuv also supports semaphores_, `condition variables`_ and barriers_ with APIs
-very similar to their pthread counterparts.
-
-.. _semaphores: https://en.wikipedia.org/wiki/Semaphore_(programming)
-.. _condition variables: https://en.wikipedia.org/wiki/Monitor_(synchronization)#Condition_variables_2
-.. _barriers: https://en.wikipedia.org/wiki/Barrier_(computer_science)
-
-In addition, libuv provides a convenience function ``uv_once()``. Multiple
-threads can attempt to call ``uv_once()`` with a given guard and a function
-pointer, **only the first one will win, the function will be called once and
-only once**::
-
-    /* Initialize guard */
-    static uv_once_t once_only = UV_ONCE_INIT;
-
-    int i = 0;
-
-    void increment() {
-        i++;
-    }
-
-    void thread1() {
-        /* ... work */
-        uv_once(once_only, increment);
-    }
-
-    void thread2() {
-        /* ... work */
-        uv_once(once_only, increment);
-    }
-
-    int main() {
-        /* ... spawn threads */
-    }
-
-After all threads are done, ``i == 1``.
-
-.. _libuv-work-queue:
-
-libuv v0.11.11 onwards also added a ``uv_key_t`` struct and api_ for
-thread-local storage.
-
-.. _api: http://docs.libuv.org/en/v1.x/threading.html#thread-local-storage
-
-libuv work queue
-----------------
-
-``uv_queue_work()`` is a convenience function that allows an application to run
-a task in a separate thread, and have a callback that is triggered when the
-task is done. A seemingly simple function, what makes ``uv_queue_work()``
-tempting is that it allows potentially any third-party libraries to be used
-with the event-loop paradigm. When you use event loops, it is *imperative to
-make sure that no function which runs periodically in the loop thread blocks
-when performing I/O or is a serious CPU hog*, because this means that the loop
-slows down and events are not being handled at full capacity.
-
-However, a lot of existing code out there features blocking functions (for example
-a routine which performs I/O under the hood) to be used with threads if you
-want responsiveness (the classic 'one thread per client' server model), and
-getting them to play with an event loop library generally involves rolling your
-own system of running the task in a separate thread.  libuv just provides
-a convenient abstraction for this.
-
-Here is a simple example inspired by `node.js is cancer`_. We are going to
-calculate fibonacci numbers, sleeping a bit along the way, but run it in
-a separate thread so that the blocking and CPU bound task does not prevent the
-event loop from performing other activities.
-
-.. rubric:: queue-work/main.c - lazy fibonacci
-.. literalinclude:: ../../code/queue-work/main.c
-    :language: c
-    :linenos:
-    :lines: 17-29
-
-The actual task function is simple, nothing to show that it is going to be
-run in a separate thread. The ``uv_work_t`` structure is the clue. You can pass
-arbitrary data through it using the ``void* data`` field and use it to
-communicate to and from the thread. But be sure you are using proper locks if
-you are changing things while both threads may be running.
-
-The trigger is ``uv_queue_work``:
-
-.. rubric:: queue-work/main.c
-.. literalinclude:: ../../code/queue-work/main.c
-    :language: c
-    :linenos:
-    :lines: 31-44
-    :emphasize-lines: 10
-
-The thread function will be launched in a separate thread, passed the
-``uv_work_t`` structure and once the function returns, the *after* function
-will be called on the thread the event loop is running in. It will be passed
-the same structure.
-
-For writing wrappers to blocking libraries, a common :ref:`pattern <baton>`
-is to use a baton to exchange data.
-
-Since libuv version `0.9.4` an additional function, ``uv_cancel()``, is
-available. This allows you to cancel tasks on the libuv work queue. Only tasks
-that *are yet to be started* can be cancelled. If a task has *already started
-executing, or it has finished executing*, ``uv_cancel()`` **will fail**.
-
-``uv_cancel()`` is useful to cleanup pending tasks if the user requests
-termination. For example, a music player may queue up multiple directories to
-be scanned for audio files. If the user terminates the program, it should quit
-quickly and not wait until all pending requests are run.
-
-Let's modify the fibonacci example to demonstrate ``uv_cancel()``. We first set
-up a signal handler for termination.
-
-.. rubric:: queue-cancel/main.c
-.. literalinclude:: ../../code/queue-cancel/main.c
-    :language: c
-    :linenos:
-    :lines: 43-
-
-When the user triggers the signal by pressing ``Ctrl+C`` we send
-``uv_cancel()`` to all the workers. ``uv_cancel()`` will return ``0`` for those that are already executing or finished.
-
-.. rubric:: queue-cancel/main.c
-.. literalinclude:: ../../code/queue-cancel/main.c
-    :language: c
-    :linenos:
-    :lines: 33-41
-    :emphasize-lines: 6
-
-For tasks that do get cancelled successfully, the *after* function is called
-with ``status`` set to ``UV_ECANCELED``.
-
-.. rubric:: queue-cancel/main.c
-.. literalinclude:: ../../code/queue-cancel/main.c
-    :language: c
-    :linenos:
-    :lines: 28-31
-    :emphasize-lines: 2
-
-``uv_cancel()`` can also be used with ``uv_fs_t`` and ``uv_getaddrinfo_t``
-requests. For the filesystem family of functions, ``uv_fs_t.errorno`` will be
-set to ``UV_ECANCELED``.
-
-.. TIP::
-
-    A well designed program would have a way to terminate long running workers
-    that have already started executing. Such a worker could periodically check
-    for a variable that only the main process sets to signal termination.
-
-.. _inter-thread-communication:
-
-Inter-thread communication
---------------------------
-
-Sometimes you want various threads to actually send each other messages *while*
-they are running. For example you might be running some long duration task in
-a separate thread (perhaps using ``uv_queue_work``) but want to notify progress
-to the main thread. This is a simple example of having a download manager
-informing the user of the status of running downloads.
-
-.. rubric:: progress/main.c
-.. literalinclude:: ../../code/progress/main.c
-    :language: c
-    :linenos:
-    :lines: 7-8,35-
-    :emphasize-lines: 2,11
-
-The async thread communication works *on loops* so although any thread can be
-the message sender, only threads with libuv loops can be receivers (or rather
-the loop is the receiver). libuv will invoke the callback (``print_progress``)
-with the async watcher whenever it receives a message.
-
-.. warning::
-
-    It is important to realize that since the message send is *async*, the callback
-    may be invoked immediately after ``uv_async_send`` is called in another
-    thread, or it may be invoked after some time. libuv may also combine
-    multiple calls to ``uv_async_send`` and invoke your callback only once. The
-    only guarantee that libuv makes is -- The callback function is called *at
-    least once* after the call to ``uv_async_send``. If you have no pending
-    calls to ``uv_async_send``, the callback won't be called. If you make two
-    or more calls, and libuv hasn't had a chance to run the callback yet, it
-    *may* invoke your callback *only once* for the multiple invocations of
-    ``uv_async_send``. Your callback will never be called twice for just one
-    event.
-
-.. rubric:: progress/main.c
-.. literalinclude:: ../../code/progress/main.c
-    :language: c
-    :linenos:
-    :lines: 10-24
-    :emphasize-lines: 7-8
-
-In the download function, we modify the progress indicator and queue the message
-for delivery with ``uv_async_send``. Remember: ``uv_async_send`` is also
-non-blocking and will return immediately.
-
-.. rubric:: progress/main.c
-.. literalinclude:: ../../code/progress/main.c
-    :language: c
-    :linenos:
-    :lines: 31-34
-
-The callback is a standard libuv pattern, extracting the data from the watcher.
-
-Finally it is important to remember to clean up the watcher.
-
-.. rubric:: progress/main.c
-.. literalinclude:: ../../code/progress/main.c
-    :language: c
-    :linenos:
-    :lines: 26-29
-    :emphasize-lines: 3
-
-After this example, which showed the abuse of the ``data`` field, bnoordhuis_
-pointed out that using the ``data`` field is not thread safe, and
-``uv_async_send()`` is actually only meant to wake up the event loop. Use
-a mutex or rwlock to ensure accesses are performed in the right order.
-
-.. note::
-
-    mutexes and rwlocks **DO NOT** work inside a signal handler, whereas
-    ``uv_async_send`` does.
-
-One use case where ``uv_async_send`` is required is when interoperating with
-libraries that require thread affinity for their functionality. For example in
-node.js, a v8 engine instance, contexts and its objects are bound to the thread
-that the v8 instance was started in. Interacting with v8 data structures from
-another thread can lead to undefined results. Now consider some node.js module
-which binds a third party library. It may go something like this:
-
-1. In node, the third party library is set up with a JavaScript callback to be
-   invoked for more information::
-
-    var lib = require('lib');
-    lib.on_progress(function() {
-        console.log("Progress");
-    });
-
-    lib.do();
-
-    // do other stuff
-
-2. ``lib.do`` is supposed to be non-blocking but the third party lib is
-   blocking, so the binding uses ``uv_queue_work``.
-
-3. The actual work being done in a separate thread wants to invoke the progress
-   callback, but cannot directly call into v8 to interact with JavaScript. So
-   it uses ``uv_async_send``.
-
-4. The async callback, invoked in the main loop thread, which is the v8 thread,
-   then interacts with v8 to invoke the JavaScript callback.

-Utilities
-=========
-
-This chapter catalogues tools and techniques which are useful for common tasks.
-The `libev man page`_ already covers some patterns which can be adopted to
-libuv through simple API changes. It also covers parts of the libuv API that
-don't require entire chapters dedicated to them.
-
-Timers
-------
-
-Timers invoke the callback after a certain time has elapsed since the timer was
-started. libuv timers can also be set to invoke at regular intervals instead of
-just once.
-
-Simple use is to init a watcher and start it with a ``timeout``, and optional ``repeat``.
-Timers can be stopped at any time.
-
-.. code-block:: c
-
-    uv_timer_t timer_req;
-
-    uv_timer_init(loop, &timer_req);
-    uv_timer_start(&timer_req, callback, 5000, 2000);
-
-will start a repeating timer, which first starts 5 seconds (the ``timeout``) after the execution
-of ``uv_timer_start``, then repeats every 2 seconds (the ``repeat``). Use:
-
-.. code-block:: c
-
-    uv_timer_stop(&timer_req);
-
-to stop the timer. This can be used safely from within the callback as well.
-
-The repeat interval can be modified at any time with::
-
-    uv_timer_set_repeat(uv_timer_t *timer, int64_t repeat);
-
-which will take effect **when possible**. If this function is called from
-a timer callback, it means:
-
-* If the timer was non-repeating, the timer has already been stopped. Use
-  ``uv_timer_start`` again.
-* If the timer is repeating, the next timeout has already been scheduled, so
-  the old repeat interval will be used once more before the timer switches to
-  the new interval.
-
-The utility function::
-
-    int uv_timer_again(uv_timer_t *)
-
-applies **only to repeating timers** and is equivalent to stopping the timer
-and then starting it with both initial ``timeout`` and ``repeat`` set to the
-old ``repeat`` value. If the timer hasn't been started it fails (error code
-``UV_EINVAL``) and returns -1.
-
-An actual timer example is in the :ref:`reference count section
-<reference-count>`.

-The event loop only runs as long as there are active handles. This system
-works by having every handle increase the reference count of the event loop
-when it is started and decreasing the reference count when stopped. It is also
-possible to manually change the reference count of handles using::
-
-    void uv_ref(uv_handle_t*);
-    void uv_unref(uv_handle_t*);
-
-These functions can be used to allow a loop to exit even when a watcher is
-active or to use custom objects to keep the loop alive.
-
-The latter can be used with interval timers. You might have a garbage collector
-which runs every X seconds, or your network service might send a heartbeat to
-others periodically, but you don't want to have to stop them along all clean
-exit paths or error scenarios. Or you want the program to exit when all your
-other watchers are done. In that case just unref the timer immediately after
-creation so that if it is the only watcher running then ``uv_run`` will still
-exit.
-
-This is also used in node.js where some libuv methods are being bubbled up to
-the JS API. A ``uv_handle_t`` (the superclass of all watchers) is created per
-JS object and can be ref/unrefed.

-    :emphasize-lines: 9
-
-We initialize the garbage collector timer, then immediately ``unref`` it.
-Observe how after 9 seconds, when the fake job is done, the program
-automatically exits, even though the garbage collector is still running.
-
-Idler pattern
--------------
-
-The callbacks of idle handles are invoked once per event loop. The idle
-callback can be used to perform some very low priority activity. For example,
-you could dispatch a summary of the daily application performance to the
-developers for analysis during periods of idleness, or use the application's
-CPU time to perform SETI calculations :) An idle watcher is also useful in
-a GUI application. Say you are using an event loop for a file download. If the
-TCP socket is still being established and no other events are present your
-event loop will pause (**block**), which means your progress bar will freeze
-and the user will face an unresponsive application. In such a case queue up and
-idle watcher to keep the UI operational.

-    :language: c
-    :linenos:
-    :lines: 5-9, 34-
-    :emphasize-lines: 13
-
-Here we initialize the idle watcher and queue it up along with the actual
-events we are interested in. ``crunch_away`` will now be called repeatedly
-until the user types something and presses Return. Then it will be interrupted
-for a brief amount as the loop deals with the input data, after which it will
-keep calling the idle callback again.

-Passing data to worker thread
------------------------------
-
-When using ``uv_queue_work`` you'll usually need to pass complex data through
-to the worker thread. The solution is to use a ``struct`` and set
-``uv_work_t.data`` to point to it. A slight variation is to have the
-``uv_work_t`` itself as the first member of this struct (called a baton [#]_).
-This allows cleaning up the work request and all the data in one free call.
-
-.. code-block:: c
-    :linenos:
-    :emphasize-lines: 2
-
-    struct ftp_baton {
-        uv_work_t req;
-        char *host;
-        int port;
-        char *username;
-        char *password;
-    }
-
-.. code-block:: c
-    :linenos:
-    :emphasize-lines: 2
-
-    ftp_baton *baton = (ftp_baton*) malloc(sizeof(ftp_baton));
-    baton->req.data = (void*) baton;
-    baton->host = strdup("my.webhost.com");
-    baton->port = 21;
-    // ...
-
-    uv_queue_work(loop, &baton->req, ftp_session, ftp_cleanup);
-
-Here we create the baton and queue the task.
-
-Now the task function can extract the data it needs:
-
-.. code-block:: c
-    :linenos:
-    :emphasize-lines: 2, 12
-
-    void ftp_session(uv_work_t *req) {
-        ftp_baton *baton = (ftp_baton*) req->data;
-
-        fprintf(stderr, "Connecting to %s\n", baton->host);
-    }
-
-    void ftp_cleanup(uv_work_t *req) {
-        ftp_baton *baton = (ftp_baton*) req->data;
-
-        free(baton->host);
-        // ...
-        free(baton);
-    }
-
-We then free the baton which also frees the watcher.
-
-External I/O with polling
--------------------------
-
-Usually third-party libraries will handle their own I/O, and keep track of
-their sockets and other files internally. In this case it isn't possible to use
-the standard stream I/O operations, but the library can still be integrated
-into the libuv event loop. All that is required is that the library allow you
-to access the underlying file descriptors and provide functions that process
-tasks in small increments as decided by your application. Some libraries though
-will not allow such access, providing only a standard blocking function which
-will perform the entire I/O transaction and only then return. It is unwise to
-use these in the event loop thread, use the :ref:`threadpool` instead. Of
-course, this will also mean losing granular control on the library.
-
-The ``uv_poll`` section of libuv simply watches file descriptors using the
-operating system notification mechanism. In some sense, all the I/O operations
-that libuv implements itself are also backed by ``uv_poll`` like code. Whenever
-the OS notices a change of state in file descriptors being polled, libuv will
-invoke the associated callback.
-
-Here we will walk through a simple download manager that will use libcurl_ to
-download files. Rather than give all control to libcurl, we'll instead be
-using the libuv event loop, and use the non-blocking, async multi_ interface to
-progress with the download whenever libuv notifies of I/O readiness.

-    :emphasize-lines: 7,21,24-25
-
-The way each library is integrated with libuv will vary. In the case of
-libcurl, we can register two callbacks. The socket callback ``handle_socket``
-is invoked whenever the state of a socket changes and we have to start polling
-it. ``start_timeout`` is called by libcurl to notify us of the next timeout
-interval, after which we should drive libcurl forward regardless of I/O status.
-This is so that libcurl can handle errors or do whatever else is required to
-get the download moving.
-
-Our downloader is to be invoked as::
-
-    $ ./uvwget [url1] [url2] ...
-
-So we add each argument as a URL

-    :lines: 39-56
-    :emphasize-lines: 13-14
-
-We let libcurl directly write the data to a file, but much more is possible if
-you so desire.
-
-``start_timeout`` will be called immediately the first time by libcurl, so
-things are set in motion. This simply starts a libuv `timer <#timers>`_ which
-drives ``curl_multi_socket_action`` with ``CURL_SOCKET_TIMEOUT`` whenever it
-times out. ``curl_multi_socket_action`` is what drives libcurl, and what we
-call whenever sockets change state. But before we go into that, we need to poll
-on sockets whenever ``handle_socket`` is called.

-    :emphasize-lines: 9,11,15,21,24
-
-We are interested in the socket fd ``s``, and the ``action``. For every socket
-we create a ``uv_poll_t`` handle if it doesn't exist, and associate it with the
-socket using ``curl_multi_assign``. This way ``socketp`` points to it whenever
-the callback is invoked.
-
-In the case that the download is done or fails, libcurl requests removal of the
-poll. So we stop and free the poll handle.
-
-Depending on what events libcurl wishes to watch for, we start polling with
-``UV_READABLE`` or ``UV_WRITABLE``. Now libuv will invoke the poll callback
-whenever the socket is ready for reading or writing. Calling ``uv_poll_start``
-multiple times on the same handle is acceptable, it will just update the events
-mask with the new value. ``curl_perform`` is the crux of this program.

-    :emphasize-lines: 2,6-7,12
-
-The first thing we do is to stop the timer, since there has been some progress
-in the interval. Then depending on what event triggered the callback, we set
-the correct flags. Then we call ``curl_multi_socket_action`` with the socket
-that progressed and the flags informing about what events happened. At this
-point libcurl does all of its internal tasks in small increments, and will
-attempt to return as fast as possible, which is exactly what an evented program
-wants in its main thread. libcurl keeps queueing messages into its own queue
-about transfer progress. In our case we are only interested in transfers that
-are completed. So we extract these messages, and clean up handles whose
-transfers are done.

-Loading libraries
------------------
-
-libuv provides a cross platform API to dynamically load `shared libraries`_.
-This can be used to implement your own plugin/extension/module system and is
-used by node.js to implement ``require()`` support for bindings. The usage is
-quite simple as long as your library exports the right symbols. Be careful with
-sanity and security checks when loading third party code, otherwise your
-program will behave unpredictably. This example implements a very simple
-plugin system which does nothing except print the name of the plugin.
-
-Let us first look at the interface provided to plugin authors.
-
-.. rubric:: plugin/plugin.h
-.. literalinclude:: ../../code/plugin/plugin.h
-    :language: c
-    :linenos:
-
-You can similarly add more functions that plugin authors can use to do useful
-things in your application [#]_. A sample plugin using this API is:
-
-.. rubric:: plugin/hello.c
-.. literalinclude:: ../../code/plugin/hello.c
-    :language: c
-    :linenos:
-
-Our interface defines that all plugins should have an ``initialize`` function
-which will be called by the application. This plugin is compiled as a shared
-library and can be loaded by running our application::
-
-    $ ./plugin libhello.dylib
-    Loading libhello.dylib
-    Registered plugin "Hello World!"
-
-.. NOTE::
-
-    The shared library filename will be different depending on platforms. On
-    Linux it is ``libhello.so``.
-
-This is done by using ``uv_dlopen`` to first load the shared library
-``libhello.dylib``. Then we get access to the ``initialize`` function using
-``uv_dlsym`` and invoke it.
-
-.. rubric:: plugin/main.c
-.. literalinclude:: ../../code/plugin/main.c
-    :language: c
-    :linenos:
-    :lines: 7-
-    :emphasize-lines: 15, 18, 24
-
-``uv_dlopen`` expects a path to the shared library and sets the opaque
-``uv_lib_t`` pointer. It returns 0 on success, -1 on error. Use ``uv_dlerror``
-to get the error message.
-
-``uv_dlsym`` stores a pointer to the symbol in the second argument in the third
-argument. ``init_plugin_function`` is a function pointer to the sort of
-function we are looking for in the application's plugins.

-TTY
----
-
-Text terminals have supported basic formatting for a long time, with a `pretty
-standardised`_ command set. This formatting is often used by programs to
-improve the readability of terminal output. For example ``grep --colour``.
-libuv provides the ``uv_tty_t`` abstraction (a stream) and related functions to
-implement the ANSI escape codes across all platforms. By this I mean that libuv
-converts ANSI codes to the Windows equivalent, and provides functions to get
-terminal information.
-
-.. _pretty standardised: https://en.wikipedia.org/wiki/ANSI_escape_sequences
-
-The first thing to do is to initialize a ``uv_tty_t`` with the file descriptor
-it reads/writes from. This is achieved with::
-
-    int uv_tty_init(uv_loop_t*, uv_tty_t*, uv_file fd, int unused)
-
-The ``unused`` parameter is now auto-detected and ignored. It previously needed
-to be set to use ``uv_read_start()`` on the stream.
-
-It is then best to use ``uv_tty_set_mode`` to set the mode to *normal*
-which enables most TTY formatting, flow-control and other settings. Other_ modes
-are also available.
-
-.. _Other: http://docs.libuv.org/en/v1.x/tty.html#c.uv_tty_mode_t
-
-Remember to call ``uv_tty_reset_mode`` when your program exits to restore the
-state of the terminal. Just good manners. Another set of good manners is to be
-aware of redirection. If the user redirects the output of your command to
-a file, control sequences should not be written as they impede readability and
-``grep``. To check if the file descriptor is indeed a TTY, call
-``uv_guess_handle`` with the file descriptor and compare the return value with
-``UV_TTY``.
-
-Here is a simple example which prints white text on a red background:
-
-.. rubric:: tty/main.c
-.. literalinclude:: ../../code/tty/main.c
-    :language: c
-    :linenos:
-    :emphasize-lines: 11-12,14,17,27
-
-The final TTY helper is ``uv_tty_get_winsize()`` which is used to get the
-width and height of the terminal and returns ``0`` on success. Here is a small
-program which does some animation using the function and character position
-escape codes.
-
-.. rubric:: tty-gravity/main.c
-.. literalinclude:: ../../code/tty-gravity/main.c
-    :language: c
-    :linenos:
-    :emphasize-lines: 19,25,38
-
-The escape codes are:
-
-======  =======================
-Code    Meaning
-======  =======================
-*2* J    Clear part of the screen, 2 is entire screen
-H        Moves cursor to certain position, default top-left
-*n* B    Moves cursor down by n lines
-*n* C    Moves cursor right by n columns
-m        Obeys string of display settings, in this case green background (40+2), white text (30+7)
-======  =======================
-
-As you can see this is very useful to produce nicely formatted output, or even
-console based arcade games if that tickles your fancy. For fancier control you
-can try `ncurses`_.
-
-.. _ncurses: https://www.gnu.org/software/ncurses/ncurses.html
-
-.. versionchanged:: 1.23.1: the `readable` parameter is now unused and ignored.
-                    The appropriate value will now be auto-detected from the kernel.

-:c:type:`uv_handle_t` --- Base handle
-=====================================
-
-`uv_handle_t` is the base type for all libuv handle types.
-
-Structures are aligned so that any libuv handle can be cast to `uv_handle_t`.
-All API functions defined here work with any handle type.
-
-Libuv handles are not movable. Pointers to handle structures passed to
-functions must remain valid for the duration of the requested operation. Take
-care when using stack allocated handles.

-
-    Union of all handle types.
-
-.. c:type:: void (*uv_alloc_cb)(uv_handle_t* handle, size_t suggested_size, uv_buf_t* buf)
-
-    Type definition for callback passed to :c:func:`uv_read_start` and
-    :c:func:`uv_udp_recv_start`. The user must allocate memory and fill the supplied
-    :c:type:`uv_buf_t` structure. If NULL is assigned as the buffer's base or 0 as its length,
-    a ``UV_ENOBUFS`` error will be triggered in the :c:type:`uv_udp_recv_cb` or the
-    :c:type:`uv_read_cb` callback.
-
-    Each buffer is used only once and the user is responsible for freeing it in the
-    :c:type:`uv_udp_recv_cb` or the :c:type:`uv_read_cb` callback.
-
-    A suggested size (65536 at the moment in most cases) is provided, but it's just an indication,
-    not related in any way to the pending data to be read. The user is free to allocate the amount
-    of memory they decide.
-
-    As an example, applications with custom allocation schemes such as using freelists, allocation
-    pools or slab based allocators may decide to use a different size which matches the memory
-    chunks they already have.
-
-    Example:
-
-    ::
-
-        static void my_alloc_cb(uv_handle_t* handle, size_t suggested_size, uv_buf_t* buf) {

-API
----
-
-.. c:macro:: UV_HANDLE_TYPE_MAP(iter_macro)
-
-    Macro that expands to a series of invocations of `iter_macro` for
-    each of the handle types. `iter_macro` is invoked with two
-    arguments: the name of the `uv_handle_type` element without the
-    `UV_` prefix, and the name of the corresponding structure type
-    without the `uv_` prefix and `_t` suffix.
-
-.. c:function:: int uv_is_active(const uv_handle_t* handle)
-
-    Returns non-zero if the handle is active, zero if it's inactive. What
-    "active" means depends on the type of handle:
-
-    - A uv_async_t handle is always active and cannot be deactivated, except
-      by closing it with uv_close().
-
-    - A uv_pipe_t, uv_tcp_t, uv_udp_t, etc. handle - basically any handle that
-      deals with i/o - is active when it is doing something that involves i/o,
-      like reading, writing, connecting, accepting new connections, etc.
-
-    - A uv_check_t, uv_idle_t, uv_timer_t, etc. handle is active when it has
-      been started with a call to uv_check_start(), uv_idle_start(), etc.
-
-    Rule of thumb: if a handle of type `uv_foo_t` has a `uv_foo_start()`
-    function, then it's active from the moment that function is called.
-    Likewise, `uv_foo_stop()` deactivates the handle again.
-
-.. c:function:: int uv_is_closing(const uv_handle_t* handle)
-
-    Returns non-zero if the handle is closing or closed, zero otherwise.
-
-    .. note::
-        This function should only be used between the initialization of the handle and the
-        arrival of the close callback.
-
-.. c:function:: void uv_close(uv_handle_t* handle, uv_close_cb close_cb)
-
-    Request handle to be closed. `close_cb` will be called asynchronously after
-    this call. This MUST be called on each handle before memory is released.
-    Moreover, the memory can only be released in `close_cb` or after it has
-    returned.
-
-    Handles that wrap file descriptors are closed immediately but
-    `close_cb` will still be deferred to the next iteration of the event loop.
-    It gives you a chance to free up any resources associated with the handle.
-
-    In-progress requests, like uv_connect_t or uv_write_t, are cancelled and
-    have their callbacks called asynchronously with status=UV_ECANCELED.
-
-    `close_cb` can be `NULL` in cases where no cleanup or deallocation is
-    necessary.
-
-.. c:function:: void uv_ref(uv_handle_t* handle)
-
-    Reference the given handle. References are idempotent, that is, if a handle
-    is already referenced calling this function again will have no effect.
-
-    See :ref:`refcount`.
-
-.. c:function:: void uv_unref(uv_handle_t* handle)
-
-    Un-reference the given handle. References are idempotent, that is, if a handle
-    is not referenced calling this function again will have no effect.
-
-    See :ref:`refcount`.
-
-.. c:function:: int uv_has_ref(const uv_handle_t* handle)
-
-    Returns non-zero if the handle referenced, zero otherwise.
-
-    See :ref:`refcount`.
-
-.. c:function:: size_t uv_handle_size(uv_handle_type type)
-
-    Returns the size of the given handle type. Useful for FFI binding writers
-    who don't want to know the structure layout.
-
-
-Miscellaneous API functions
----------------------------
-
-The following API functions take a :c:type:`uv_handle_t` argument but they work
-just for some handle types.
-
-.. c:function:: int uv_send_buffer_size(uv_handle_t* handle, int* value)
-
-    Gets or sets the size of the send buffer that the operating
-    system uses for the socket.
-
-    If `*value` == 0, then it will set `*value` to the current send buffer size.
-    If `*value` > 0 then it will use `*value` to set the new send buffer size.
-
-    On success, zero is returned. On error, a negative result is
-    returned.
-
-    This function works for TCP, pipe and UDP handles on Unix and for TCP and
-    UDP handles on Windows.
-
-    .. note::
-        Linux will set double the size and return double the size of the original set value.
-
-.. c:function:: int uv_recv_buffer_size(uv_handle_t* handle, int* value)
-
-    Gets or sets the size of the receive buffer that the operating
-    system uses for the socket.
-
-    If `*value` == 0, then it will set `*value` to the current receive buffer size.
-    If `*value` > 0 then it will use `*value` to set the new receive buffer size.
-
-    On success, zero is returned. On error, a negative result is
-    returned.
-
-    This function works for TCP, pipe and UDP handles on Unix and for TCP and
-    UDP handles on Windows.
-
-    .. note::
-        Linux will set double the size and return double the size of the original set value.
-
-.. c:function:: int uv_fileno(const uv_handle_t* handle, uv_os_fd_t* fd)
-
-    Gets the platform dependent file descriptor equivalent.
-
-    The following handles are supported: TCP, pipes, TTY, UDP and poll. Passing
-    any other handle type will fail with `UV_EINVAL`.
-
-    If a handle doesn't have an attached file descriptor yet or the handle
-    itself has been closed, this function will return `UV_EBADF`.
-
-    .. warning::
-        Be very careful when using this function. libuv assumes it's in control of the file
-        descriptor so any change to it may lead to malfunction.
-
-.. c:function:: uv_loop_t* uv_handle_get_loop(const uv_handle_t* handle)
-
-    Returns `handle->loop`.
-
-    .. versionadded:: 1.19.0

-.. c:function:: void* uv_handle_get_data(const uv_handle_t* handle)
-
-    Returns `handle->data`.
-

-
-.. c:function:: uv_handle_type uv_handle_get_type(const uv_handle_t* handle)
-
-    Returns `handle->type`.
-
-    .. versionadded:: 1.19.0
-
-.. c:function:: const char* uv_handle_type_name(uv_handle_type type)
-
-    Returns the name for the equivalent struct for a given handle type,
-    e.g. `"pipe"` (as in :c:type:`uv_pipe_t`) for `UV_NAMED_PIPE`.
-
-    If no such handle type exists, this returns `NULL`.
-
-    .. versionadded:: 1.19.0
-
-.. _refcount:
-
-Reference counting
-------------------
-
-The libuv event loop (if run in the default mode) will run until there are no
-active `and` referenced handles left. The user can force the loop to exit early
-by unreferencing handles which are active, for example by calling :c:func:`uv_unref`
-after calling :c:func:`uv_timer_start`.
-
-A handle can be referenced or unreferenced, the refcounting scheme doesn't use
-a counter, so both operations are idempotent.
-
-All handles are referenced when active by default, see :c:func:`uv_is_active`
-for a more detailed explanation on what being `active` involves.

-
-:c:type:`uv_loop_t` --- Event loop
-==================================
-
-The event loop is the central part of libuv's functionality. It takes care
-of polling for i/o and scheduling callbacks to be run based on different sources
-of events.
-
-
-Data types
-----------
-
-.. c:type:: uv_loop_t
-
-    Loop data type.
-
-.. c:enum:: uv_run_mode
-
-    Mode used to run the loop with :c:func:`uv_run`.
-
-    ::
-
-        typedef enum {
-            UV_RUN_DEFAULT = 0,
-            UV_RUN_ONCE,
-            UV_RUN_NOWAIT

-
-
-Public members
-^^^^^^^^^^^^^^
-
-.. c:member:: void* uv_loop_t.data
-
-    Space for user-defined arbitrary data. libuv does not use and does not
-    touch this field.
-
-
-API
----
-
-.. c:function:: int uv_loop_init(uv_loop_t* loop)
-
-    Initializes the given `uv_loop_t` structure.
-
-.. c:function:: int uv_loop_configure(uv_loop_t* loop, uv_loop_option option, ...)
-
-    .. versionadded:: 1.0.2
-
-    Set additional loop options.  You should normally call this before the
-    first call to :c:func:`uv_run` unless mentioned otherwise.
-
-    Returns 0 on success or a UV_E* error code on failure.  Be prepared to
-    handle UV_ENOSYS; it means the loop option is not supported by the platform.
-
-    Supported options:
-
-    - UV_LOOP_BLOCK_SIGNAL: Block a signal when polling for new events.  The
-      second argument to :c:func:`uv_loop_configure` is the signal number.
-
-      This operation is currently only implemented for SIGPROF signals,
-      to suppress unnecessary wakeups when using a sampling profiler.
-      Requesting other signals will fail with UV_EINVAL.
-
-    - UV_METRICS_IDLE_TIME: Accumulate the amount of idle time the event loop
-      spends in the event provider.
-
-      This option is necessary to use :c:func:`uv_metrics_idle_time`.
-
-    .. versionchanged:: 1.39.0 added the UV_METRICS_IDLE_TIME option.
-
-.. c:function:: int uv_loop_close(uv_loop_t* loop)
-
-    Releases all internal loop resources. Call this function only when the loop
-    has finished executing and all open handles and requests have been closed,
-    or it will return UV_EBUSY. After this function returns, the user can free
-    the memory allocated for the loop.
-
-.. c:function:: uv_loop_t* uv_default_loop(void)
-
-    Returns the initialized default loop. It may return NULL in case of
-    allocation failure.
-
-    This function is just a convenient way for having a global loop throughout
-    an application, the default loop is in no way different than the ones
-    initialized with :c:func:`uv_loop_init`. As such, the default loop can (and
-    should) be closed with :c:func:`uv_loop_close` so the resources associated
-    with it are freed.
-
-    .. warning::
-        This function is not thread safe.
-
-.. c:function:: int uv_run(uv_loop_t* loop, uv_run_mode mode)
-
-    This function runs the event loop. It will act differently depending on the
-    specified mode:
-
-    - UV_RUN_DEFAULT: Runs the event loop until there are no more active and
-      referenced handles or requests. Returns non-zero if :c:func:`uv_stop`
-      was called and there are still active handles or requests.  Returns
-      zero in all other cases.
-    - UV_RUN_ONCE: Poll for i/o once. Note that this function blocks if
-      there are no pending callbacks. Returns zero when done (no active handles
-      or requests left), or non-zero if more callbacks are expected (meaning
-      you should run the event loop again sometime in the future).
-    - UV_RUN_NOWAIT: Poll for i/o once but don't block if there are no
-      pending callbacks. Returns zero if done (no active handles
-      or requests left), or non-zero if more callbacks are expected (meaning
-      you should run the event loop again sometime in the future).
-
-    :c:func:`uv_run` is not reentrant. It must not be called from a callback.
-
-.. c:function:: int uv_loop_alive(const uv_loop_t* loop)
-
-    Returns non-zero if there are referenced active handles, active
-    requests or closing handles in the loop.
-
-.. c:function:: void uv_stop(uv_loop_t* loop)
-
-    Stop the event loop, causing :c:func:`uv_run` to end as soon as
-    possible. This will happen not sooner than the next loop iteration.
-    If this function was called before blocking for i/o, the loop won't block
-    for i/o on this iteration.
-
-.. c:function:: size_t uv_loop_size(void)
-
-    Returns the size of the `uv_loop_t` structure. Useful for FFI binding
-    writers who don't want to know the structure layout.
-
-.. c:function:: int uv_backend_fd(const uv_loop_t* loop)
-
-    Get backend file descriptor. Only kqueue, epoll and event ports are
-    supported.
-
-    This can be used in conjunction with `uv_run(loop, UV_RUN_NOWAIT)` to
-    poll in one thread and run the event loop's callbacks in another see
-    test/test-embed.c for an example.
-
-    .. note::
-        Embedding a kqueue fd in another kqueue pollset doesn't work on all platforms. It's not
-        an error to add the fd but it never generates events.
-
-.. c:function:: int uv_backend_timeout(const uv_loop_t* loop)
-
-    Get the poll timeout. The return value is in milliseconds, or -1 for no
-    timeout.
-
-.. c:function:: uint64_t uv_now(const uv_loop_t* loop)
-
-    Return the current timestamp in milliseconds. The timestamp is cached at
-    the start of the event loop tick, see :c:func:`uv_update_time` for details
-    and rationale.
-
-    The timestamp increases monotonically from some arbitrary point in time.
-    Don't make assumptions about the starting point, you will only get
-    disappointed.
-
-    .. note::
-        Use :c:func:`uv_hrtime` if you need sub-millisecond granularity.
-
-.. c:function:: void uv_update_time(uv_loop_t* loop)
-
-    Update the event loop's concept of "now". Libuv caches the current time
-    at the start of the event loop tick in order to reduce the number of
-    time-related system calls.
-
-    You won't normally need to call this function unless you have callbacks
-    that block the event loop for longer periods of time, where "longer" is
-    somewhat subjective but probably on the order of a millisecond or more.
-
-.. c:function:: void uv_walk(uv_loop_t* loop, uv_walk_cb walk_cb, void* arg)
-
-    Walk the list of handles: `walk_cb` will be executed with the given `arg`.
-
-.. c:function:: int uv_loop_fork(uv_loop_t* loop)
-
-    .. versionadded:: 1.12.0
-
-    Reinitialize any kernel state necessary in the child process after
-    a :man:`fork(2)` system call.
-
-    Previously started watchers will continue to be started in the
-    child process.
-
-    It is necessary to explicitly call this function on every event
-    loop created in the parent process that you plan to continue to
-    use in the child, including the default loop (even if you don't
-    continue to use it in the parent). This function must be called
-    before calling :c:func:`uv_run` or any other API function using
-    the loop in the child. Failure to do so will result in undefined
-    behaviour, possibly including duplicate events delivered to both
-    parent and child or aborting the child process.
-
-    When possible, it is preferred to create a new loop in the child
-    process instead of reusing a loop created in the parent. New loops
-    created in the child process after the fork should not use this
-    function.
-
-    This function is not implemented on Windows, where it returns ``UV_ENOSYS``.
-
-    .. caution::
-
-       This function is experimental. It may contain bugs, and is subject to
-       change or removal. API and ABI stability is not guaranteed.
-
-    .. note::
-
-        On Mac OS X, if directory FS event handles were in use in the
-        parent process *for any event loop*, the child process will no
-        longer be able to use the most efficient FSEvent
-        implementation. Instead, uses of directory FS event handles in
-        the child will fall back to the same implementation used for
-        files and on other kqueue-based systems.
-
-    .. caution::
-
-       On AIX and SunOS, FS event handles that were already started in
-       the parent process at the time of forking will *not* deliver
-       events in the child process; they must be closed and restarted.
-       On all other platforms, they will continue to work normally
-       without any further intervention.
-
-    .. caution::
-
-       Any previous value returned from :c:func:`uv_backend_fd` is now
-       invalid. That function must be called again to determine the
-       correct backend file descriptor.
-
-.. c:function:: void* uv_loop_get_data(const uv_loop_t* loop)
-
-    Returns `loop->data`.
-
-    .. versionadded:: 1.19.0
-
-.. c:function:: void* uv_loop_set_data(uv_loop_t* loop, void* data)
-
-    Sets `loop->data` to `data`.

-libuv 0.10 -> 1.0.0 migration guide
-===================================
-
-Some APIs changed quite a bit throughout the 1.0.0 development process. Here
-is a migration guide for the most significant changes that happened after 0.10
-was released.
-
-
-Loop initialization and closing
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-In libuv 0.10 (and previous versions), loops were created with `uv_loop_new`, which
-allocated memory for a new loop and initialized it; and destroyed with `uv_loop_delete`,
-which destroyed the loop and freed the memory. Starting with 1.0, those are deprecated
-and the user is responsible for allocating the memory and then initializing the loop.
-
-libuv 0.10
-
-::
-
-    uv_loop_t* loop = uv_loop_new();
-    ...
-    uv_loop_delete(loop);
-
-libuv 1.0
-
-::
-
-    uv_loop_t* loop = malloc(sizeof *loop);
-    uv_loop_init(loop);
-    ...
-    uv_loop_close(loop);
-    free(loop);
-
-.. note::
-    Error handling was omitted for brevity. Check the documentation for :c:func:`uv_loop_init`
-    and :c:func:`uv_loop_close`.
-
-
-Error handling
-~~~~~~~~~~~~~~
-
-Error handling had a major overhaul in libuv 1.0. In general, functions and status parameters
-would get 0 for success and -1 for failure on libuv 0.10, and the user had to use `uv_last_error`
-to fetch the error code, which was a positive number.
-
-In 1.0, functions and status parameters contain the actual error code, which is 0 for success, or
-a negative number in case of error.
-
-libuv 0.10
-
-::
-
-    ... assume 'server' is a TCP server which is already listening
-    r = uv_listen((uv_stream_t*) server, 511, NULL);
-    if (r == -1) {
-      uv_err_t err = uv_last_error(uv_default_loop());
-      /* err.code contains UV_EADDRINUSE */
-    }
-
-libuv 1.0
-
-::
-
-    ... assume 'server' is a TCP server which is already listening
-    r = uv_listen((uv_stream_t*) server, 511, NULL);
-    if (r < 0) {
-      /* r contains UV_EADDRINUSE */
-    }
-
-
-Threadpool changes
-~~~~~~~~~~~~~~~~~~
-
-In libuv 0.10 Unix used a threadpool which defaulted to 4 threads, while Windows used the
-`QueueUserWorkItem` API, which uses a Windows internal threadpool, which defaults to 512
-threads per process.
-
-In 1.0, we unified both implementations, so Windows now uses the same implementation Unix
-does. The threadpool size can be set by exporting the ``UV_THREADPOOL_SIZE`` environment
-variable. See :c:ref:`threadpool`.
-
-
-Allocation callback API change
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-In libuv 0.10 the callback had to return a filled :c:type:`uv_buf_t` by value:
-
-::
-
-    uv_buf_t alloc_cb(uv_handle_t* handle, size_t size) {
-        return uv_buf_init(malloc(size), size);
-    }
-
-In libuv 1.0 a pointer to a buffer is passed to the callback, which the user
-needs to fill:
-
-::
-
-    void alloc_cb(uv_handle_t* handle, size_t size, uv_buf_t* buf) {
-        buf->base = malloc(size);
-        buf->len = size;
-    }
-
-
-Unification of IPv4 / IPv6 APIs
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-libuv 1.0 unified the IPv4 and IPv6 APIS. There is no longer a `uv_tcp_bind` and `uv_tcp_bind6`
-duality, there is only :c:func:`uv_tcp_bind` now.
-
-IPv4 functions took ``struct sockaddr_in`` structures by value, and IPv6 functions took
-``struct sockaddr_in6``. Now functions take a ``struct sockaddr*`` (note it's a pointer).
-It can be stack allocated.
-
-libuv 0.10
-
-::
-
-    struct sockaddr_in addr = uv_ip4_addr("0.0.0.0", 1234);
-    ...
-    uv_tcp_bind(&server, addr)
-
-libuv 1.0
-
-::
-
-    struct sockaddr_in addr;
-    uv_ip4_addr("0.0.0.0", 1234, &addr)
-    ...
-    uv_tcp_bind(&server, (const struct sockaddr*) &addr, 0);
-
-The IPv4 and IPv6 struct creating functions (:c:func:`uv_ip4_addr` and :c:func:`uv_ip6_addr`)
-have also changed, make sure you check the documentation.
-
-..note::
-    This change applies to all functions that made a distinction between IPv4 and IPv6
-    addresses.
-
-
-Streams / UDP  data receive callback API change
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The streams and UDP data receive callbacks now get a pointer to a :c:type:`uv_buf_t` buffer,
-not a structure by value.
-
-libuv 0.10
-
-::
-
-    void on_read(uv_stream_t* handle,
-                 ssize_t nread,
-                 uv_buf_t buf) {
-        ...
-    }
-
-    void recv_cb(uv_udp_t* handle,
-                 ssize_t nread,
-                 uv_buf_t buf,
-                 struct sockaddr* addr,
-                 unsigned flags) {
-        ...
-    }
-
-libuv 1.0
-
-::
-
-    void on_read(uv_stream_t* handle,
-                 ssize_t nread,
-                 const uv_buf_t* buf) {
-        ...
-    }
-
-    void recv_cb(uv_udp_t* handle,
-                 ssize_t nread,
-                 const uv_buf_t* buf,
-                 const struct sockaddr* addr,
-                 unsigned flags) {
-        ...
-    }
-
-
-Receiving handles over pipes API change
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-In libuv 0.10 (and earlier versions) the `uv_read2_start` function was used to start reading
-data on a pipe, which could also result in the reception of handles over it. The callback
-for such function looked like this:
-
-::
-
-    void on_read(uv_pipe_t* pipe,
-                 ssize_t nread,
-                 uv_buf_t buf,
-                 uv_handle_type pending) {
-        ...
-    }
-
-In libuv 1.0, `uv_read2_start` was removed, and the user needs to check if there are pending
-handles using :c:func:`uv_pipe_pending_count` and :c:func:`uv_pipe_pending_type` while in
-the read callback:
-
-::
-
-    void on_read(uv_stream_t* handle,
-                 ssize_t nread,
-                 const uv_buf_t* buf) {
-        ...
-        while (uv_pipe_pending_count((uv_pipe_t*) handle) != 0) {
-            pending = uv_pipe_pending_type((uv_pipe_t*) handle);
-            ...
-        }
-        ...
-    }
-
-
-Extracting the file descriptor out of a handle
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-While it wasn't supported by the API, users often accessed the libuv internals in
-order to get access to the file descriptor of a TCP handle, for example.
-
-::
-
-    fd = handle->io_watcher.fd;
-
-This is now properly exposed through the :c:func:`uv_fileno` function.
-
-
-uv_fs_readdir rename and API change
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-`uv_fs_readdir` returned a list of strings in the `req->ptr` field upon completion in
-libuv 0.10. In 1.0, this function got renamed to :c:func:`uv_fs_scandir`, since it's
-actually implemented using ``scandir(3)``.
-
-In addition, instead of allocating a full list strings, the user is able to get one
-result at a time by using the :c:func:`uv_fs_scandir_next` function. This function
-does not need to make a roundtrip to the threadpool, because libuv will keep the
-list of *dents* returned by ``scandir(3)`` around.

-API
----
-
-.. c:function:: uv_handle_type uv_guess_handle(uv_file file)
-
-    Used to detect what type of stream should be used with a given file
-    descriptor. Usually this will be used during initialization to guess the
-    type of the stdio streams.
-
-    For :man:`isatty(3)` equivalent functionality use this function and test
-    for `UV_TTY`.
-
-.. c:function:: int uv_replace_allocator(uv_malloc_func malloc_func, uv_realloc_func realloc_func, uv_calloc_func calloc_func, uv_free_func free_func)
-
-    .. versionadded:: 1.6.0
-
-    Override the use of the standard library's :man:`malloc(3)`,
-    :man:`calloc(3)`, :man:`realloc(3)`, :man:`free(3)`, memory allocation
-    functions.
-
-    This function must be called before any other libuv function is called or
-    after all resources have been freed and thus libuv doesn't reference
-    any allocated memory chunk.
-
-    On success, it returns 0, if any of the function pointers is `NULL` it
-    returns `UV_EINVAL`.
-
-    .. warning:: There is no protection against changing the allocator multiple
-                 times. If the user changes it they are responsible for making
-                 sure the allocator is changed while no memory was allocated with
-                 the previous allocator, or that they are compatible.
-
-    .. warning:: Allocator must be thread-safe.
-
-.. c:function:: void uv_library_shutdown(void);
-
-    .. versionadded:: 1.38.0
-
-    Release any global state that libuv is holding onto. Libuv will normally
-    do so automatically when it is unloaded but it can be instructed to perform
-    cleanup manually.
-
-    .. warning:: Only call :c:func:`uv_library_shutdown()` once.
-
-    .. warning:: Don't call :c:func:`uv_library_shutdown()` when there are
-                 still event loops or I/O requests active.
-
-    .. warning:: Don't call libuv functions after calling
-                 :c:func:`uv_library_shutdown()`.
-
-.. c:function:: uv_buf_t uv_buf_init(char* base, unsigned int len)
-
-    Constructor for :c:type:`uv_buf_t`.
-
-    Due to platform differences the user cannot rely on the ordering of the
-    `base` and `len` members of the uv_buf_t struct. The user is responsible for
-    freeing `base` after the uv_buf_t is done. Return struct passed by value.
-
-.. c:function:: char** uv_setup_args(int argc, char** argv)
-
-    Store the program arguments. Required for getting / setting the process title
-    or the executable path. Libuv may take ownership of the memory that `argv` 
-    points to. This function should be called exactly once, at program start-up.
-
-    Example:
-
-    ::
-
-        argv = uv_setup_args(argc, argv);  /* May return a copy of argv. */
-
-
-.. c:function:: int uv_get_process_title(char* buffer, size_t size)
-
-    Gets the title of the current process. You *must* call `uv_setup_args`
-    before calling this function on Unix and AIX systems. If `uv_setup_args`
-    has not been called on systems that require it, then `UV_ENOBUFS` is
-    returned. If `buffer` is `NULL` or `size` is zero, `UV_EINVAL` is returned.
-    If `size` cannot accommodate the process title and terminating `nul`
-    character, the function returns `UV_ENOBUFS`.
-
-    .. note::
-        On BSD systems, `uv_setup_args` is needed for getting the initial process
-        title. The process title returned will be an empty string until either
-        `uv_setup_args` or `uv_set_process_title` is called.
-
-    .. versionchanged:: 1.18.1 now thread-safe on all supported platforms.
-
-    .. versionchanged:: 1.39.0 now returns an error if `uv_setup_args` is needed
-                        but hasn't been called.
-
-.. c:function:: int uv_set_process_title(const char* title)
-
-    Sets the current process title. You *must* call `uv_setup_args` before
-    calling this function on Unix and AIX systems. If `uv_setup_args` has not
-    been called on systems that require it, then `UV_ENOBUFS` is returned. On
-    platforms with a fixed size buffer for the process title the contents of
-    `title` will be copied to the buffer and truncated if larger than the
-    available space. Other platforms will return `UV_ENOMEM` if they cannot
-    allocate enough space to duplicate the contents of `title`.
-
-    .. versionchanged:: 1.18.1 now thread-safe on all supported platforms.
-
-    .. versionchanged:: 1.39.0 now returns an error if `uv_setup_args` is needed
-                        but hasn't been called.
-
-.. c:function:: int uv_resident_set_memory(size_t* rss)
-
-    Gets the resident set size (RSS) for the current process.
-
-.. c:function:: int uv_uptime(double* uptime)
-
-    Gets the current system uptime. Depending on the system full or fractional seconds are returned.
-
-.. c:function:: int uv_getrusage(uv_rusage_t* rusage)
-
-    Gets the resource usage measures for the current process.
-
-    .. note::
-        On Windows not all fields are set, the unsupported fields are filled with zeroes.
-        See :c:type:`uv_rusage_t` for more details.
-
-.. c:function:: uv_pid_t uv_os_getpid(void)
-
-    Returns the current process ID.
-
-    .. versionadded:: 1.18.0
-
-.. c:function:: uv_pid_t uv_os_getppid(void)
-
-    Returns the parent process ID.
-
-    .. versionadded:: 1.16.0
-
-.. c:function:: unsigned int uv_available_parallelism(void)
-
-    Returns an estimate of the default amount of parallelism a program should
-    use. Always returns a non-zero value.
-
-    On Linux, inspects the calling thread's CPU affinity mask to determine if
-    it has been pinned to specific CPUs.
-
-    On Windows, the available parallelism may be underreported on systems with
-    more than 64 logical CPUs.
-
-    On other platforms, reports the number of CPUs that the operating system
-    considers to be online.
-
-    .. versionadded:: 1.44.0
-
-.. c:function:: int uv_cpu_info(uv_cpu_info_t** cpu_infos, int* count)
-
-    Gets information about the CPUs on the system. The `cpu_infos` array will
-    have `count` elements and needs to be freed with :c:func:`uv_free_cpu_info`.
-
-    Use :c:func:`uv_available_parallelism` if you need to know how many CPUs
-    are available for threads or child processes.
-
-.. c:function:: void uv_free_cpu_info(uv_cpu_info_t* cpu_infos, int count)
-
-    Frees the `cpu_infos` array previously allocated with :c:func:`uv_cpu_info`.
-
-.. c:function:: int uv_cpumask_size(void)
-
-    Returns the maximum size of the mask used for process/thread affinities,
-    or `UV_ENOTSUP` if affinities are not supported on the current platform.
-
-    .. versionadded:: 1.45.0
-
-.. c:function:: int uv_interface_addresses(uv_interface_address_t** addresses, int* count)
-
-    Gets address information about the network interfaces on the system. An
-    array of `count` elements is allocated and returned in `addresses`. It must
-    be freed by the user, calling :c:func:`uv_free_interface_addresses`.
-
-.. c:function:: void uv_free_interface_addresses(uv_interface_address_t* addresses, int count)
-
-    Free an array of :c:type:`uv_interface_address_t` which was returned by
-    :c:func:`uv_interface_addresses`.
-
-.. c:function:: void uv_loadavg(double avg[3])
-
-    Gets the load average. See: `<https://en.wikipedia.org/wiki/Load_(computing)>`_
-
-    .. note::
-        Returns [0,0,0] on Windows (i.e., it's not implemented).
-
-.. c:function:: int uv_ip4_addr(const char* ip, int port, struct sockaddr_in* addr)
-
-    Convert a string containing an IPv4 addresses to a binary structure.
-
-.. c:function:: int uv_ip6_addr(const char* ip, int port, struct sockaddr_in6* addr)
-
-    Convert a string containing an IPv6 addresses to a binary structure.

-    Convert a binary structure containing an IPv4 address to a string.
-
-.. c:function:: int uv_ip6_name(const struct sockaddr_in6* src, char* dst, size_t size)
-
-    Convert a binary structure containing an IPv6 address to a string.
-
-.. c:function:: int uv_ip_name(const struct sockaddr *src, char *dst, size_t size)
-
-    Convert a binary structure containing an IPv4 address or an IPv6 address to a string.
-
-.. c:function:: int uv_inet_ntop(int af, const void* src, char* dst, size_t size)
-.. c:function:: int uv_inet_pton(int af, const char* src, void* dst)
-
-    Cross-platform IPv6-capable implementation of :man:`inet_ntop(3)`
-    and :man:`inet_pton(3)`. On success they return 0. In case of error
-    the target `dst` pointer is unmodified.
-
-.. c:macro:: UV_IF_NAMESIZE
-
-    Maximum IPv6 interface identifier name length.  Defined as
-    `IFNAMSIZ` on Unix and `IF_NAMESIZE` on Linux and Windows.
-
-    .. versionadded:: 1.16.0
-
-.. c:function:: int uv_if_indextoname(unsigned int ifindex, char* buffer, size_t* size)
-
-    IPv6-capable implementation of :man:`if_indextoname(3)`. When called,
-    `*size` indicates the length of the `buffer`, which is used to store the
-    result.
-    On success, zero is returned, `buffer` contains the interface name, and
-    `*size` represents the string length of the `buffer`, excluding the NUL
-    terminator byte from `*size`. On error, a negative result is
-    returned. If `buffer` is not large enough to hold the result,
-    `UV_ENOBUFS` is returned, and `*size` represents the necessary size in
-    bytes, including the NUL terminator byte into the `*size`.
-
-    On Unix, the returned interface name can be used directly as an
-    interface identifier in scoped IPv6 addresses, e.g.
-    `fe80::abc:def1:2345%en0`.
-
-    On Windows, the returned interface cannot be used as an interface
-    identifier, as Windows uses numerical interface identifiers, e.g.
-    `fe80::abc:def1:2345%5`.
-
-    To get an interface identifier in a cross-platform compatible way,
-    use `uv_if_indextoiid()`.
-
-    Example:
-
-    ::
-
-        char ifname[UV_IF_NAMESIZE];
-        size_t size = sizeof(ifname);
-        uv_if_indextoname(sin6->sin6_scope_id, ifname, &size);
-
-    .. versionadded:: 1.16.0
-
-.. c:function:: int uv_if_indextoiid(unsigned int ifindex, char* buffer, size_t* size)
-
-    Retrieves a network interface identifier suitable for use in an IPv6 scoped
-    address. On Windows, returns the numeric `ifindex` as a string. On all other
-    platforms, `uv_if_indextoname()` is called. The result is written to
-    `buffer`, with `*size` indicating the length of `buffer`. If `buffer` is not
-    large enough to hold the result, then `UV_ENOBUFS` is returned, and `*size`
-    represents the size, including the NUL byte, required to hold the
-    result.
-
-    See `uv_if_indextoname` for further details.
-
-    .. versionadded:: 1.16.0
-
-.. c:function:: int uv_exepath(char* buffer, size_t* size)
-
-    Gets the executable path. You *must* call `uv_setup_args` before calling
-    this function.
-
-.. c:function:: int uv_cwd(char* buffer, size_t* size)
-
-    Gets the current working directory, and stores it in `buffer`. If the
-    current working directory is too large to fit in `buffer`, this function
-    returns `UV_ENOBUFS`, and sets `size` to the required length, including the
-    null terminator.
-
-    .. versionchanged:: 1.1.0
-
-        On Unix the path no longer ends in a slash.
-
-    .. versionchanged:: 1.9.0 the returned length includes the terminating null
-                        byte on `UV_ENOBUFS`, and the buffer is null terminated
-                        on success.
-
-
-.. c:function:: int uv_chdir(const char* dir)
-
-    Changes the current working directory.
-
-.. c:function:: int uv_os_homedir(char* buffer, size_t* size)
-
-    Gets the current user's home directory. On Windows, `uv_os_homedir()` first
-    checks the `USERPROFILE` environment variable using
-    `GetEnvironmentVariableW()`. If `USERPROFILE` is not set,
-    `GetUserProfileDirectoryW()` is called. On all other operating systems,
-    `uv_os_homedir()` first checks the `HOME` environment variable using
-    :man:`getenv(3)`. If `HOME` is not set, :man:`getpwuid_r(3)` is called. The
-    user's home directory is stored in `buffer`. When `uv_os_homedir()` is
-    called, `size` indicates the maximum size of `buffer`. On success `size` is set
-    to the string length of `buffer`. On `UV_ENOBUFS` failure `size` is set to the
-    required length for `buffer`, including the null byte.
-
-    .. warning::
-        `uv_os_homedir()` is not thread safe.
-
-    .. versionadded:: 1.6.0
-
-.. c:function:: int uv_os_tmpdir(char* buffer, size_t* size)
-
-    Gets the temp directory. On Windows, `uv_os_tmpdir()` uses `GetTempPathW()`.
-    On all other operating systems, `uv_os_tmpdir()` uses the first environment
-    variable found in the ordered list `TMPDIR`, `TMP`, `TEMP`, and `TEMPDIR`.
-    If none of these are found, the path `"/tmp"` is used, or, on Android,
-    `"/data/local/tmp"` is used. The temp directory is stored in `buffer`. When
-    `uv_os_tmpdir()` is called, `size` indicates the maximum size of `buffer`.
-    On success `size` is set to the string length of `buffer` (which does not
-    include the terminating null). On `UV_ENOBUFS` failure `size` is set to the
-    required length for `buffer`, including the null byte.
-
-    .. warning::
-        `uv_os_tmpdir()` is not thread safe.
-
-    .. versionadded:: 1.9.0
-
-.. c:function:: int uv_os_get_passwd(uv_passwd_t* pwd)
-
-    Gets a subset of the password file entry for the current effective uid (not
-    the real uid). The populated data includes the username, euid, gid, shell,
-    and home directory. On non-Windows systems, all data comes from
-    :man:`getpwuid_r(3)`. On Windows, uid and gid are set to -1 and have no
-    meaning, and shell is `NULL`. After successfully calling this function, the
-    memory allocated to `pwd` needs to be freed with
-    :c:func:`uv_os_free_passwd`.
-
-    .. versionadded:: 1.9.0
-
-.. c:function:: void uv_os_free_passwd(uv_passwd_t* pwd)
-
-    Frees the `pwd` memory previously allocated with :c:func:`uv_os_get_passwd`.
-
-    .. versionadded:: 1.9.0
-
-.. c:function:: uint64_t uv_get_free_memory(void)
-
-    Gets the amount of free memory available in the system, as reported by
-    the kernel (in bytes). Returns 0 when unknown.
-
-.. c:function:: uint64_t uv_get_total_memory(void)
-
-    Gets the total amount of physical memory in the system (in bytes).
-    Returns 0 when unknown.
-
-.. c:function:: uint64_t uv_get_constrained_memory(void)
-
-    Gets the total amount of memory available to the process (in bytes) based on
-    limits imposed by the OS. If there is no such constraint, or the constraint
-    is unknown, `0` is returned. If there is a constraining mechanism, but there
-    is no constraint set, `UINT64_MAX` is returned. Note that it is not unusual
-    for this value to be less than or greater than :c:func:`uv_get_total_memory`.
-
-    .. note::
-        This function currently only returns a non-zero value on Linux, based
-        on cgroups if it is present, and on z/OS based on RLIMIT_MEMLIMIT.
-
-    .. versionadded:: 1.29.0
-
-.. c:function:: uint64_t uv_get_available_memory(void)
-
-    Gets the amount of free memory that is still available to the process (in bytes).
-    This differs from :c:func:`uv_get_free_memory` in that it takes into account any
-    limits imposed by the OS. If there is no such constraint, or the constraint
-    is unknown, the amount returned will be identical to :c:func:`uv_get_free_memory`.
-
-    .. note::
-        This function currently only returns a value that is different from
-        what :c:func:`uv_get_free_memory` reports on Linux, based
-        on cgroups if it is present.
-
-    .. versionadded:: 1.45.0
-
-.. c:function:: uint64_t uv_hrtime(void)
-
-    Returns the current high-resolution timestamp. This is expressed in
-    nanoseconds. It is relative to an arbitrary time in the past. It is not
-    related to the time of day and therefore not subject to clock drift. The
-    primary use is for measuring performance between intervals.
-
-    .. note::
-        Not every platform can support nanosecond resolution; however, this value will always
-        be in nanoseconds.
-
-.. c:function:: int uv_clock_gettime(uv_clock_id clock_id, uv_timespec64_t* ts)
-
-    Obtain the current system time from a high-resolution real-time or monotonic
-    clock source.
-
-    The real-time clock counts from the UNIX epoch (1970-01-01) and is subject
-    to time adjustments; it can jump back in time.
-
-    The monotonic clock counts from an arbitrary point in the past and never
-    jumps back in time.
-
-    .. versionadded:: 1.45.0
-
-.. c:function:: void uv_print_all_handles(uv_loop_t* loop, FILE* stream)
-
-    Prints all handles associated with the given `loop` to the given `stream`.
-
-    Example:
-
-    ::
-
-        uv_print_all_handles(uv_default_loop(), stderr);
-        /*
-        [--I] signal   0x1a25ea8

-        [R--] idle     0x1a7a8c8
-        */
-
-    The format is `[flags] handle-type handle-address`. For `flags`:
-
-    - `R` is printed for a handle that is referenced
-    - `A` is printed for a handle that is active
-    - `I` is printed for a handle that is internal
-

-
-.. c:function:: void uv_print_active_handles(uv_loop_t* loop, FILE* stream)
-
-    This is the same as :c:func:`uv_print_all_handles` except only active handles
-    are printed.

-
-    .. versionadded:: 1.31.0
-
-.. c:function:: int uv_os_getenv(const char* name, char* buffer, size_t* size)
-
-    Retrieves the environment variable specified by `name`, copies its value
-    into `buffer`, and sets `size` to the string length of the value. When
-    calling this function, `size` must be set to the amount of storage available
-    in `buffer`, including the null terminator. If the environment variable
-    exceeds the storage available in `buffer`, `UV_ENOBUFS` is returned, and
-    `size` is set to the amount of storage required to hold the value. If no
-    matching environment variable exists, `UV_ENOENT` is returned.
-
-    .. warning::
-        This function is not thread safe.

-
-    .. versionadded:: 1.12.0
-
-.. c:function:: int uv_os_gethostname(char* buffer, size_t* size)
-
-    Returns the hostname as a null-terminated string in `buffer`, and sets
-    `size` to the string length of the hostname. When calling this function,
-    `size` must be set to the amount of storage available in `buffer`, including
-    the null terminator. If the hostname exceeds the storage available in
-    `buffer`, `UV_ENOBUFS` is returned, and `size` is set to the amount of
-    storage required to hold the value.
-
-    .. versionadded:: 1.12.0
-
-    .. versionchanged:: 1.26.0 `UV_MAXHOSTNAMESIZE` is available and represents

-
-.. c:function:: int uv_os_getpriority(uv_pid_t pid, int* priority)
-
-    Retrieves the scheduling priority of the process specified by `pid`. The
-    returned value of `priority` is between -20 (high priority) and 19 (low
-    priority).
-
-    .. note::

-
-.. c:function:: int uv_os_setpriority(uv_pid_t pid, int priority)
-
-    Sets the scheduling priority of the process specified by `pid`. The
-    `priority` value range is between -20 (high priority) and 19 (low priority).
-    The constants `UV_PRIORITY_LOW`, `UV_PRIORITY_BELOW_NORMAL`,
-    `UV_PRIORITY_NORMAL`, `UV_PRIORITY_ABOVE_NORMAL`, `UV_PRIORITY_HIGH`, and
-    `UV_PRIORITY_HIGHEST` are also provided for convenience.
-
-    .. note::
-        On Windows, this function utilizes `SetPriorityClass()`. The `priority`
-        argument is mapped to a Windows priority class. When retrieving the
-        process priority, the result will equal one of the `UV_PRIORITY`
-        constants, and not necessarily the exact value of `priority`.
-
-    .. note::
-        On Windows, setting `PRIORITY_HIGHEST` will only work for elevated user,
-        for others it will be silently reduced to `PRIORITY_HIGH`.
-
-    .. note::
-        On IBM i PASE, the highest process priority is -10. The constant
-        `UV_PRIORITY_HIGHEST` is -10, `UV_PRIORITY_HIGH` is -7,

-
-    .. versionadded:: 1.23.0
-
-.. c:function:: int uv_os_uname(uv_utsname_t* buffer)
-
-    Retrieves system information in `buffer`. The populated data includes the
-    operating system name, release, version, and machine. On non-Windows
-    systems, `uv_os_uname()` is a thin wrapper around :man:`uname(2)`. Returns
-    zero on success, and a non-zero error value otherwise.
-
-    .. versionadded:: 1.25.0
-
-.. c:function:: int uv_gettimeofday(uv_timeval64_t* tv)
-
-    Cross-platform implementation of :man:`gettimeofday(2)`. The timezone

-
-    .. versionadded:: 1.28.0
-
-.. c:function:: int uv_random(uv_loop_t* loop, uv_random_t* req, void* buf, size_t buflen, unsigned int flags, uv_random_cb cb)
-
-    Fill `buf` with exactly `buflen` cryptographically strong random bytes
-    acquired from the system CSPRNG. `flags` is reserved for future extension
-    and must currently be 0.
-
-    Short reads are not possible. When less than `buflen` random bytes are
-    available, a non-zero error value is returned or passed to the callback.
-
-    The synchronous version may block indefinitely when not enough entropy
-    is available. The asynchronous version may not ever finish when the system
-    is low on entropy.
-
-    Sources of entropy:
-
-    - Windows: `RtlGenRandom <https://docs.microsoft.com/en-us/windows/desktop/api/ntsecapi/nf-ntsecapi-rtlgenrandom>_`.
-    - Linux, Android: :man:`getrandom(2)` if available, or :man:`urandom(4)`
-      after reading from `/dev/random` once, or the `KERN_RANDOM`
-      :man:`sysctl(2)`.
-    - FreeBSD: `getrandom(2) <https://www.freebsd.org/cgi/man.cgi?query=getrandom&sektion=2>_`,

-
-.. c:function:: size_t uv_utf16_length_as_wtf8(const uint16_t* utf16, ssize_t utf16_len)
-
-    Get the length of a UTF-16 (or UCS-2) `utf16` value after converting it to
-    WTF-8. If `utf16` is NUL terminated, `utf16_len` can be set to -1,

-.. c:function:: int uv_utf16_to_wtf8(const uint16_t* utf16, ssize_t utf16_len, char** wtf8_ptr, size_t* wtf8_len_ptr)
-
-    Convert UTF-16 (or UCS-2) data in `utf16` to WTF-8 data in `*wtf8_ptr`. The
-    `utf16_len` count (in characters) gives the length of `utf16`. If `utf16`
-    is NUL terminated, `utf16_len` can be set to -1, otherwise it must be
-    specified. If `wtf8_ptr` is `NULL`, no result will be computed, but the
-    length (equal to `uv_utf16_length_as_wtf8`) will be stored in `wtf8_ptr`.
-    If `*wtf8_ptr` is `NULL`, space for the conversion will be allocated and
-    returned in `wtf8_ptr` and the length will be returned in `wtf8_len_ptr`.
-    Otherwise, the length of `*wtf8_ptr` must be passed in `wtf8_len_ptr`. The
-    `wtf8_ptr` must contain an extra space for an extra NUL after the result.
-    If the result is truncated, `UV_ENOBUFS` will be returned and
-    `wtf8_len_ptr` will be the length of the required `wtf8_ptr` to contain the
-    whole result.

-:c:type:`uv_pipe_t` --- Pipe handle
-===================================
-
-Pipe handles provide an abstraction over streaming files on Unix (including
-local domain sockets, pipes, and FIFOs) and named pipes on Windows.
-
-:c:type:`uv_pipe_t` is a 'subclass' of :c:type:`uv_stream_t`.
-
-
-Data types
-----------
-
-.. c:type:: uv_pipe_t
-
-    Pipe handle type.
-
-
-Public members
-^^^^^^^^^^^^^^
-
-.. c:member:: int uv_pipe_t.ipc
-
-    Whether this pipe is suitable for handle passing between processes.
-    Only a connected pipe that will be passing the handles should have this flag
-    set, not the listening pipe that uv_accept is called on.
-
-.. seealso:: The :c:type:`uv_stream_t` members also apply.
-
-
-API
----
-
-.. c:function:: int uv_pipe_init(uv_loop_t* loop, uv_pipe_t* handle, int ipc)
-
-    Initialize a pipe handle. The `ipc` argument is a boolean to indicate if
-    this pipe will be used for handle passing between processes (which may
-    change the bytes on the wire). Only a connected pipe that will be
-    passing the handles should have this flag set, not the listening pipe
-    that uv_accept is called on.
-
-.. c:function:: int uv_pipe_open(uv_pipe_t* handle, uv_file file)
-
-    Open an existing file descriptor or HANDLE as a pipe.
-
-    .. versionchanged:: 1.2.1 the file descriptor is set to non-blocking mode.
-
-    .. note::
-        The passed file descriptor or HANDLE is not checked for its type, but
-        it's required that it represents a valid pipe.
-
-.. c:function:: int uv_pipe_bind(uv_pipe_t* handle, const char* name)
-
-    Bind the pipe to a file path (Unix) or a name (Windows).
-
-    Does not support Linux abstract namespace sockets,
-    unlike :c:func:`uv_pipe_bind2`.
-
-    Alias for ``uv_pipe_bind2(handle, name, strlen(name), 0)``.
-
-    .. note::
-        Paths on Unix get truncated to ``sizeof(sockaddr_un.sun_path)`` bytes,
-        typically between 92 and 108 bytes.
-
-.. c:function:: int uv_pipe_bind2(uv_pipe_t* handle, const char* name, size_t namelen, unsigned int flags)
-
-    Bind the pipe to a file path (Unix) or a name (Windows).
-
-    ``flags`` must be zero or ``UV_PIPE_NO_TRUNCATE``. Returns ``UV_EINVAL``
-    for unsupported flags without performing the bind operation.
-
-    Supports Linux abstract namespace sockets. ``namelen`` must include
-    the leading nul byte but not the trailing nul byte.
-
-    .. versionadded:: 1.46.0

-
-:c:type:`uv_poll_t` --- Poll handle
-===================================
-
-Poll handles are used to watch file descriptors for readability,
-writability and disconnection similar to the purpose of :man:`poll(2)`.
-
-The purpose of poll handles is to enable integrating external libraries that
-rely on the event loop to signal it about the socket status changes, like
-c-ares or libssh2. Using uv_poll_t for any other purpose is not recommended;
-:c:type:`uv_tcp_t`, :c:type:`uv_udp_t`, etc. provide an implementation that is faster and
-more scalable than what can be achieved with :c:type:`uv_poll_t`, especially on
-Windows.
-
-It is possible that poll handles occasionally signal that a file descriptor is
-readable or writable even when it isn't. The user should therefore always
-be prepared to handle EAGAIN or equivalent when it attempts to read from or
-write to the fd.
-
-It is not okay to have multiple active poll handles for the same socket, this
-can cause libuv to busyloop or otherwise malfunction.
-
-The user should not close a file descriptor while it is being polled by an
-active poll handle. This can cause the handle to report an error,
-but it might also start polling another socket. However the fd can be safely
-closed immediately after a call to :c:func:`uv_poll_stop` or :c:func:`uv_close`.
-
-.. note::
-    On windows only sockets can be polled with poll handles. On Unix any file
-    descriptor that would be accepted by :man:`poll(2)` can be used.
-
-.. note::
-    On AIX, watching for disconnection is not supported.

----
-
-.. c:function:: int uv_poll_init(uv_loop_t* loop, uv_poll_t* handle, int fd)
-
-    Initialize the handle using a file descriptor.
-
-    .. versionchanged:: 1.2.2 the file descriptor is set to non-blocking mode.
-
-.. c:function:: int uv_poll_init_socket(uv_loop_t* loop, uv_poll_t* handle, uv_os_sock_t socket)
-
-    Initialize the handle using a socket descriptor. On Unix this is identical
-    to :c:func:`uv_poll_init`. On windows it takes a SOCKET handle.
-
-    .. versionchanged:: 1.2.2 the socket is set to non-blocking mode.
-
-.. c:function:: int uv_poll_start(uv_poll_t* handle, int events, uv_poll_cb cb)
-
-    Starts polling the file descriptor. `events` is a bitmask made up of
-    `UV_READABLE`, `UV_WRITABLE`, `UV_PRIORITIZED` and `UV_DISCONNECT`. As soon
-    as an event is detected the callback will be called with `status` set to 0,
-    and the detected events set on the `events` field.
-
-    The `UV_PRIORITIZED` event is used to watch for sysfs interrupts or TCP
-    out-of-band messages.
-
-    The `UV_DISCONNECT` event is optional in the sense that it may not be
-    reported and the user is free to ignore it, but it can help optimize the
-    shutdown path because an extra read or write call might be avoided.
-
-    If an error happens while polling, `status` will be < 0 and corresponds
-    with one of the `UV_E*` error codes (see :ref:`errors`). The user should
-    not close the socket while the handle is active. If the user does that
-    anyway, the callback *may* be called reporting an error status, but this is
-    **not** guaranteed. If `status == UV_EBADF` polling is discontinued for the
-    file handle and no further events will be reported. The user should
-    then call :c:func:`uv_close` on the handle.
-
-    .. note::
-        Calling :c:func:`uv_poll_start` on a handle that is already active is
-        fine. Doing so will update the events mask that is being watched for.
-
-    .. note::
-        Though `UV_DISCONNECT` can be set, it is unsupported on AIX and as such
-        will not be set on the `events` field in the callback.
-
-    .. note::
-        If one of the events `UV_READABLE` or `UV_WRITABLE` are set, the
-        callback will be called again, as long as the given fd/socket remains
-        readable or writable accordingly. Particularly in each of the following
-        scenarios:
-
-        * The callback has been called because the socket became
-          readable/writable and the callback did not conduct a read/write on
-          this socket at all.
-        * The callback committed a read on the socket, and has not read all the
-          available data (when `UV_READABLE` is set).
-        * The callback committed a write on the socket, but it remained
-          writable afterwards (when `UV_WRITABLE` is set).
-        * The socket has already became readable/writable before calling
-          :c:func:`uv_poll_start` on a poll handle associated with this socket,
-          and since then the state of the socket did not changed.
-
-        In all of the above listed scenarios, the socket remains readable or
-        writable and hence the callback will be called again (depending on the
-        events set in the bitmask). This behaviour is known as level
-        triggering.
-
-    .. versionchanged:: 1.9.0 Added the `UV_DISCONNECT` event.
-    .. versionchanged:: 1.14.0 Added the `UV_PRIORITIZED` event.
-
-.. c:function:: int uv_poll_stop(uv_poll_t* poll)
-
-    Stop polling the file descriptor, the callback will no longer be called.
-
-    .. note::
-        Calling :c:func:`uv_poll_stop` is effective immediately: any pending
-        callback is also canceled, even if the socket state change notification
-        was already pending.

-    Libuv can change the child process' user/group id. This happens only when
-    the appropriate bits are set in the flags fields.
-
-    .. note::
-        This is not supported on Windows, :c:func:`uv_spawn` will fail and set the error
-        to ``UV_ENOTSUP``.
-

-
-    Flags specifying how the stdio container should be passed to the child.

-.. c:member:: union @0 uv_stdio_container_t.data
-
-    Union containing either the `stream` or `fd` to be passed on to the child
-    process.

----
-
-.. c:function:: void uv_disable_stdio_inheritance(void)
-
-    Disables inheritance for file descriptors / handles that this process
-    inherited from its parent. The effect is that child processes spawned by
-    this process don't accidentally inherit these handles.
-
-    It is recommended to call this function as early in your program as possible,
-    before the inherited file descriptors can be closed or duplicated.
-
-    .. note::
-        This function works on a best-effort basis: there is no guarantee that libuv can discover
-        all file descriptors that were inherited. In general it does a better job on Windows than
-        it does on Unix.
-
-.. c:function:: int uv_spawn(uv_loop_t* loop, uv_process_t* handle, const uv_process_options_t* options)
-
-    Initializes the process handle and starts the process. If the process is
-    successfully spawned, this function will return 0. Otherwise, the
-    negative error code corresponding to the reason it couldn't spawn is
-    returned.
-
-    Possible reasons for failing to spawn would include (but not be limited to)
-    the file to execute not existing, not having permissions to use the setuid or
-    setgid specified, or not having enough memory to allocate for the new
-    process.
-
-    .. versionchanged:: 1.24.0 Added `UV_PROCESS_WINDOWS_HIDE_CONSOLE` and
-                        `UV_PROCESS_WINDOWS_HIDE_GUI` flags.
-
-.. c:function:: int uv_process_kill(uv_process_t* handle, int signum)
-
-    Sends the specified signal to the given process handle. Check the documentation
-    on :c:ref:`signal` for signal support, specially on Windows.
-
-.. c:function:: int uv_kill(int pid, int signum)
-
-    Sends the specified signal to the given PID. Check the documentation
-    on :c:ref:`signal` for signal support, specially on Windows.
-
-.. c:function:: uv_pid_t uv_process_get_pid(const uv_process_t* handle)
-
-    Returns `handle->pid`.
-
-    .. versionadded:: 1.19.0
-
-.. seealso:: The :c:type:`uv_handle_t` API functions also apply.

-
-:c:type:`uv_req_t` --- Base request
-===================================
-
-`uv_req_t` is the base type for all libuv request types.
-
-Structures are aligned so that any libuv request can be cast to `uv_req_t`.
-All API functions defined here work with any request type.
-
-
-Data types
-----------
-
-.. c:type:: uv_req_t
-
-    The base libuv request structure.
-
-.. c:type:: uv_any_req
-
-    Union of all request types.
-
-
-Public members
-^^^^^^^^^^^^^^
-
-.. c:member:: void* uv_req_t.data
-
-    Space for user-defined arbitrary data. libuv does not use this field.
-
-.. c:member:: uv_req_type uv_req_t.type
-
-    Indicated the type of request. Readonly.
-
-    ::
-
-        typedef enum {
-            UV_UNKNOWN_REQ = 0,
-            UV_REQ,

-        } uv_req_type;
-
-
-API
----
-
-.. c:macro:: UV_REQ_TYPE_MAP(iter_macro)
-
-    Macro that expands to a series of invocations of `iter_macro` for
-    each of the request types. `iter_macro` is invoked with two
-    arguments: the name of the `uv_req_type` element without the `UV_`
-    prefix, and the name of the corresponding structure type without the
-    `uv_` prefix and `_t` suffix.
-
-.. c:function:: int uv_cancel(uv_req_t* req)
-
-    Cancel a pending request. Fails if the request is executing or has finished
-    executing.
-
-    Returns 0 on success, or an error code < 0 on failure.
-
-    Only cancellation of :c:type:`uv_fs_t`, :c:type:`uv_getaddrinfo_t`,
-    :c:type:`uv_getnameinfo_t`, :c:type:`uv_random_t` and :c:type:`uv_work_t`
-    requests is currently supported.
-
-    Cancelled requests have their callbacks invoked some time in the future.
-    It's **not** safe to free the memory associated with the request until the
-    callback is called.
-
-    Here is how cancellation is reported to the callback:
-
-    * A :c:type:`uv_fs_t` request has its req->result field set to `UV_ECANCELED`.
-
-    * A :c:type:`uv_work_t`, :c:type:`uv_getaddrinfo_t`,
-      :c:type:`uv_getnameinfo_t` or :c:type:`uv_random_t` request has its
-      callback invoked with status == `UV_ECANCELED`.
-
-.. c:function:: size_t uv_req_size(uv_req_type type)
-
-    Returns the size of the given request type. Useful for FFI binding writers
-    who don't want to know the structure layout.
-
-.. c:function:: void* uv_req_get_data(const uv_req_t* req)
-
-    Returns `req->data`.
-
-    .. versionadded:: 1.19.0
-
-.. c:function:: void* uv_req_set_data(uv_req_t* req, void* data)
-
-    Sets `req->data` to `data`.
-
-    .. versionadded:: 1.19.0
-
-.. c:function:: uv_req_type uv_req_get_type(const uv_req_t* req)
-
-    Returns `req->type`.
-
-    .. versionadded:: 1.19.0
-
-.. c:function:: const char* uv_req_type_name(uv_req_type type)
-
-    Returns the name for the equivalent struct for a given request type,
-    e.g. `"connect"` (as in :c:type:`uv_connect_t`) for `UV_CONNECT`.
-
-    If no such request type exists, this returns `NULL`.
-
-    .. versionadded:: 1.19.0

-.. _signal:
-
-:c:type:`uv_signal_t` --- Signal handle
-=======================================
-
-Signal handles implement Unix style signal handling on a per-event loop bases.
-
-Windows notes
--------------
-
-Reception of some signals is emulated:
-
-* SIGINT is normally delivered when the user presses CTRL+C. However, like
-  on Unix, it is not generated when terminal raw mode is enabled.
-
-* SIGBREAK is delivered when the user pressed CTRL + BREAK.
-
-* SIGHUP is generated when the user closes the console window. On SIGHUP the
-  program is given approximately 10 seconds to perform cleanup. After that
-  Windows will unconditionally terminate it.
-
-* SIGWINCH is raised whenever libuv detects that the console has been
-  resized. When a libuv app is running under a console emulator, or when a
-  32-bit libuv app is running on 64-bit system, SIGWINCH will be emulated. In
-  such cases SIGWINCH signals may not always be delivered in a timely manner.
-  For a writable :c:type:`uv_tty_t` handle libuv will only detect size changes
-  when the cursor is moved. When a readable :c:type:`uv_tty_t` handle is used,
-  resizing of the console buffer will be detected only if the handle is in raw
-  mode and is being read.
-
-* Watchers for other signals can be successfully created, but these signals
-  are never received. These signals are: `SIGILL`, `SIGABRT`, `SIGFPE`, `SIGSEGV`,
-  `SIGTERM` and `SIGKILL.`
-
-* Calls to raise() or abort() to programmatically raise a signal are
-  not detected by libuv; these will not trigger a signal watcher.
-
-.. versionchanged:: 1.15.0 SIGWINCH support on Windows was improved.
-.. versionchanged:: 1.31.0 32-bit libuv SIGWINCH support on 64-bit Windows was
-                           rolled back to old implementation.
-
-Unix notes
-----------
-
-* SIGKILL and SIGSTOP are impossible to catch.
-
-* Handling SIGBUS, SIGFPE, SIGILL or SIGSEGV via libuv results into undefined behavior.
-
-* SIGABRT will not be caught by libuv if generated by `abort()`, e.g. through `assert()`.
-
-* On Linux SIGRT0 and SIGRT1 (signals 32 and 33) are used by the NPTL pthreads library to
-  manage threads. Installing watchers for those signals will lead to unpredictable behavior
-  and is strongly discouraged. Future versions of libuv may simply reject them.
-
-
-Data types

-.. c:type:: uv_signal_t
-
-    Signal handle type.
-
-.. c:type:: void (*uv_signal_cb)(uv_signal_t* handle, int signum)

-:c:type:`uv_stream_t` --- Stream handle
-=======================================
-
-Stream handles provide an abstraction of a duplex communication channel.
-:c:type:`uv_stream_t` is an abstract type, libuv provides 3 stream implementations
-in the form of :c:type:`uv_tcp_t`, :c:type:`uv_pipe_t` and :c:type:`uv_tty_t`.
-
-
-Data types
-----------
-
-.. c:type:: uv_stream_t
-
-    Stream handle type.
-
-.. c:type:: uv_connect_t
-
-    Connect request type.
-
-.. c:type:: uv_shutdown_t
-
-    Shutdown request type.
-
-.. c:type:: uv_write_t
-
-    Write request type. Careful attention must be paid when reusing objects of
-    this type. When a stream is in non-blocking mode, write requests sent
-    with ``uv_write`` will be queued. Reusing objects at this point is undefined
-    behaviour. It is safe to reuse the ``uv_write_t`` object only after the
-    callback passed to ``uv_write`` is fired.
-
-.. c:type:: void (*uv_read_cb)(uv_stream_t* stream, ssize_t nread, const uv_buf_t* buf)
-
-    Callback called when data was read on a stream.
-
-    `nread` is > 0 if there is data available or < 0 on error. When we've
-    reached EOF, `nread` will be set to ``UV_EOF``. When `nread` < 0,
-    the `buf` parameter might not point to a valid buffer; in that case
-    `buf.len` and `buf.base` are both set to 0.
-
-    .. note::
-        `nread` might be 0, which does *not* indicate an error or EOF. This
-        is equivalent to ``EAGAIN`` or ``EWOULDBLOCK`` under ``read(2)``.
-
-    The callee is responsible for stopping/closing the stream when an error happens
-    by calling :c:func:`uv_read_stop` or :c:func:`uv_close`. Trying to read
-    from the stream again is undefined.
-
-    The callee is responsible for freeing the buffer, libuv does not reuse it.
-    The buffer may be a null buffer (where `buf->base` == NULL and `buf->len` == 0)
-    on error.
-
-.. c:type:: void (*uv_write_cb)(uv_write_t* req, int status)
-
-    Callback called after data was written on a stream. `status` will be 0 in
-    case of success, < 0 otherwise.
-
-.. c:type:: void (*uv_connect_cb)(uv_connect_t* req, int status)
-
-    Callback called after a connection started by :c:func:`uv_connect` is done.
-    `status` will be 0 in case of success, < 0 otherwise.
-
-.. c:type:: void (*uv_shutdown_cb)(uv_shutdown_t* req, int status)
-
-    Callback called after a shutdown request has been completed. `status` will
-    be 0 in case of success, < 0 otherwise.
-
-.. c:type:: void (*uv_connection_cb)(uv_stream_t* server, int status)
-
-    Callback called when a stream server has received an incoming connection.
-    The user can accept the connection by calling :c:func:`uv_accept`.
-    `status` will be 0 in case of success, < 0 otherwise.
-
-
-Public members
-^^^^^^^^^^^^^^
-
-.. c:member:: size_t uv_stream_t.write_queue_size
-

----
-
-.. c:function:: int uv_shutdown(uv_shutdown_t* req, uv_stream_t* handle, uv_shutdown_cb cb)
-
-    Shutdown the outgoing (write) side of a duplex stream. It waits for pending
-    write requests to complete. The `handle` should refer to a initialized stream.
-    `req` should be an uninitialized shutdown request struct. The `cb` is called
-    after shutdown is complete.
-
-.. c:function:: int uv_listen(uv_stream_t* stream, int backlog, uv_connection_cb cb)
-
-    Start listening for incoming connections. `backlog` indicates the number of
-    connections the kernel might queue, same as :man:`listen(2)`. When a new
-    incoming connection is received the :c:type:`uv_connection_cb` callback is
-    called.
-
-.. c:function:: int uv_accept(uv_stream_t* server, uv_stream_t* client)
-
-    This call is used in conjunction with :c:func:`uv_listen` to accept incoming
-    connections. Call this function after receiving a :c:type:`uv_connection_cb`
-    to accept the connection. Before calling this function the client handle must
-    be initialized. < 0 return value indicates an error.
-
-    When the :c:type:`uv_connection_cb` callback is called it is guaranteed that
-    this function will complete successfully the first time. If you attempt to use
-    it more than once, it may fail. It is suggested to only call this function once
-    per :c:type:`uv_connection_cb` call.
-
-    .. note::
-        `server` and `client` must be handles running on the same loop.
-
-.. c:function:: int uv_read_start(uv_stream_t* stream, uv_alloc_cb alloc_cb, uv_read_cb read_cb)
-
-    Read data from an incoming stream. The :c:type:`uv_read_cb` callback will
-    be made several times until there is no more data to read or
-    :c:func:`uv_read_stop` is called.
-
-    .. versionchanged:: 1.38.0 :c:func:`uv_read_start()` now consistently
-      returns `UV_EALREADY` when called twice, and `UV_EINVAL` when the
-      stream is closing. With older libuv versions, it returns `UV_EALREADY`
-      on Windows but not UNIX, and `UV_EINVAL` on UNIX but not Windows.
-
-.. c:function:: int uv_read_stop(uv_stream_t*)
-
-    Stop reading data from the stream. The :c:type:`uv_read_cb` callback will
-    no longer be called.
-
-    This function is idempotent and may be safely called on a stopped stream.
-
-    This function will always succeed; hence, checking its return value is
-    unnecessary. A non-zero return indicates that finishing releasing resources
-    may be pending on the next input event on that TTY on Windows, and does not
-    indicate failure.
-
-.. c:function:: int uv_write(uv_write_t* req, uv_stream_t* handle, const uv_buf_t bufs[], unsigned int nbufs, uv_write_cb cb)
-
-    Write data to stream. Buffers are written in order. Example:
-
-    ::
-
-        void cb(uv_write_t* req, int status) {
-            /* Logic which handles the write result */
-        }
-
-        uv_buf_t a[] = {
-            { .base = "1", .len = 1 },
-            { .base = "2", .len = 1 }
-        };
-
-        uv_buf_t b[] = {
-            { .base = "3", .len = 1 },
-            { .base = "4", .len = 1 }
-        };
-
-        uv_write_t req1;
-        uv_write_t req2;
-
-        /* writes "1234" */
-        uv_write(&req1, stream, a, 2, cb);
-        uv_write(&req2, stream, b, 2, cb);
-
-    .. note::
-        The memory pointed to by the buffers must remain valid until the callback gets called.
-        This also holds for :c:func:`uv_write2`.
-
-.. c:function:: int uv_write2(uv_write_t* req, uv_stream_t* handle, const uv_buf_t bufs[], unsigned int nbufs, uv_stream_t* send_handle, uv_write_cb cb)
-
-    Extended write function for sending handles over a pipe. The pipe must be
-    initialized with `ipc` == 1.
-
-    .. note::
-        `send_handle` must be a TCP, pipe and UDP handle on Unix, or a TCP
-        handle on Windows, which is a server or a connection (listening or
-        connected state). Bound sockets or pipes will be assumed to be servers.
-
-.. c:function:: int uv_try_write(uv_stream_t* handle, const uv_buf_t bufs[], unsigned int nbufs)
-
-    Same as :c:func:`uv_write`, but won't queue a write request if it can't be
-    completed immediately.
-
-    Will return either:
-
-    * > 0: number of bytes written (can be less than the supplied buffer size).
-    * < 0: negative error code (``UV_EAGAIN`` is returned if no data can be sent
-      immediately).
-
-.. c:function:: int uv_try_write2(uv_stream_t* handle, const uv_buf_t bufs[], unsigned int nbufs, uv_stream_t* send_handle)
-
-    Same as :c:func:`uv_try_write` and extended write function for sending
-    handles over a pipe like c:func:`uv_write2`.
-
-    Try to send a handle is not supported on Windows,
-    where it returns ``UV_EAGAIN``.
-
-    .. versionadded:: 1.42.0
-    
-.. c:function:: int uv_is_readable(const uv_stream_t* handle)
-
-    Returns 1 if the stream is readable, 0 otherwise.
-
-.. c:function:: int uv_is_writable(const uv_stream_t* handle)
-
-    Returns 1 if the stream is writable, 0 otherwise.
-
-.. c:function:: int uv_stream_set_blocking(uv_stream_t* handle, int blocking)
-
-    Enable or disable blocking mode for a stream.
-
-    When blocking mode is enabled all writes complete synchronously. The
-    interface remains unchanged otherwise, e.g. completion or failure of the
-    operation will still be reported through a callback which is made
-    asynchronously.
-
-    .. warning::
-        Relying too much on this API is not recommended. It is likely to change
-        significantly in the future.
-
-        Currently only works on Windows for :c:type:`uv_pipe_t` handles.
-        On UNIX platforms, all :c:type:`uv_stream_t` handles are supported.
-
-        Also libuv currently makes no ordering guarantee when the blocking mode
-        is changed after write requests have already been submitted. Therefore it is
-        recommended to set the blocking mode immediately after opening or creating
-        the stream.
-
-    .. versionchanged:: 1.4.0 UNIX implementation added.
-
-.. c:function:: size_t uv_stream_get_write_queue_size(const uv_stream_t* stream)
-
-    Returns `stream->write_queue_size`.
-
-    .. versionadded:: 1.19.0
-
-.. seealso:: The :c:type:`uv_handle_t` API functions also apply.

-:c:type:`uv_tcp_t` --- TCP handle
-=================================
-
-TCP handles are used to represent both TCP streams and servers.
-
-:c:type:`uv_tcp_t` is a 'subclass' of :c:type:`uv_stream_t`.
-

-
-
-Public members
-^^^^^^^^^^^^^^
-
-N/A
-
-.. seealso:: The :c:type:`uv_stream_t` members also apply.
-
-
-API
----
-
-.. c:function:: int uv_tcp_init(uv_loop_t* loop, uv_tcp_t* handle)
-
-    Initialize the handle. No socket is created as of yet.
-
-.. c:function:: int uv_tcp_init_ex(uv_loop_t* loop, uv_tcp_t* handle, unsigned int flags)
-
-    Initialize the handle with the specified flags. At the moment only the lower 8 bits
-    of the `flags` parameter are used as the socket domain. A socket will be created
-    for the given domain. If the specified domain is ``AF_UNSPEC`` no socket is created,
-    just like :c:func:`uv_tcp_init`.
-
-    .. versionadded:: 1.7.0
-
-.. c:function:: int uv_tcp_open(uv_tcp_t* handle, uv_os_sock_t sock)
-
-    Open an existing file descriptor or SOCKET as a TCP handle.
-
-    .. versionchanged:: 1.2.1 the file descriptor is set to non-blocking mode.
-
-    .. note::
-        The passed file descriptor or SOCKET is not checked for its type, but
-        it's required that it represents a valid stream socket.
-
-.. c:function:: int uv_tcp_nodelay(uv_tcp_t* handle, int enable)
-
-    Enable `TCP_NODELAY`, which disables Nagle's algorithm.
-
-.. c:function:: int uv_tcp_keepalive(uv_tcp_t* handle, int enable, unsigned int delay)
-
-    Enable / disable TCP keep-alive. `delay` is the initial delay in seconds,
-    ignored when `enable` is zero.
-
-    After `delay` has been reached, 10 successive probes, each spaced 1 second
-    from the previous one, will still happen. If the connection is still lost
-    at the end of this procedure, then the handle is destroyed with a
-    ``UV_ETIMEDOUT`` error passed to the corresponding callback.
-
-.. c:function:: int uv_tcp_simultaneous_accepts(uv_tcp_t* handle, int enable)
-
-    Enable / disable simultaneous asynchronous accept requests that are
-    queued by the operating system when listening for new TCP connections.
-
-    This setting is used to tune a TCP server for the desired performance.
-    Having simultaneous accepts can significantly improve the rate of accepting
-    connections (which is why it is enabled by default) but may lead to uneven
-    load distribution in multi-process setups.
-
-.. c:function:: int uv_tcp_bind(uv_tcp_t* handle, const struct sockaddr* addr, unsigned int flags)
-
-    Bind the handle to an address and port. `addr` should point to an
-    initialized ``struct sockaddr_in`` or ``struct sockaddr_in6``.
-
-    When the port is already taken, you can expect to see an ``UV_EADDRINUSE``
-    error from :c:func:`uv_listen` or :c:func:`uv_tcp_connect`. That is,
-    a successful call to this function does not guarantee that the call
-    to :c:func:`uv_listen` or :c:func:`uv_tcp_connect` will succeed as well.
-
-    `flags` can contain ``UV_TCP_IPV6ONLY``, in which case dual-stack support
-    is disabled and only IPv6 is used.
-
-.. c:function:: int uv_tcp_getsockname(const uv_tcp_t* handle, struct sockaddr* name, int* namelen)
-
-    Get the current address to which the handle is bound. `name` must point to
-    a valid and big enough chunk of memory, ``struct sockaddr_storage`` is
-    recommended for IPv4 and IPv6 support.
-
-.. c:function:: int uv_tcp_getpeername(const uv_tcp_t* handle, struct sockaddr* name, int* namelen)
-
-    Get the address of the peer connected to the handle. `name` must point to
-    a valid and big enough chunk of memory, ``struct sockaddr_storage`` is
-    recommended for IPv4 and IPv6 support.
-
-.. c:function:: int uv_tcp_connect(uv_connect_t* req, uv_tcp_t* handle, const struct sockaddr* addr, uv_connect_cb cb)
-
-    Establish an IPv4 or IPv6 TCP connection. Provide an initialized TCP handle
-    and an uninitialized :c:type:`uv_connect_t`. `addr` should point to an
-    initialized ``struct sockaddr_in`` or ``struct sockaddr_in6``.
-
-    On Windows if the `addr` is initialized to point to an unspecified address
-    (``0.0.0.0`` or ``::``) it will be changed to point to ``localhost``.
-    This is done to match the behavior of Linux systems.
-
-    The callback is made when the connection has been established or when a
-    connection error happened.
-
-    .. versionchanged:: 1.19.0 added ``0.0.0.0`` and ``::`` to ``localhost``
-        mapping
-
-.. seealso:: The :c:type:`uv_stream_t` API functions also apply.
-
-.. c:function:: int uv_tcp_close_reset(uv_tcp_t* handle, uv_close_cb close_cb)
-
-    Resets a TCP connection by sending a RST packet. This is accomplished by
-    setting the `SO_LINGER` socket option with a linger interval of zero and
-    then calling :c:func:`uv_close`.
-    Due to some platform inconsistencies, mixing of :c:func:`uv_shutdown` and
-    :c:func:`uv_tcp_close_reset` calls is not allowed.
-
-    .. versionadded:: 1.32.0
-
-.. c:function:: int uv_socketpair(int type, int protocol, uv_os_sock_t socket_vector[2], int flags0, int flags1)
-
-    Create a pair of connected sockets with the specified properties.
-    The resulting handles can be passed to `uv_tcp_open`, used with `uv_spawn`,
-    or for any other purpose.
-
-    Valid values for `flags0` and `flags1` are:
-
-      - UV_NONBLOCK_PIPE: Opens the specified socket handle for `OVERLAPPED`
-        or `FIONBIO`/`O_NONBLOCK` I/O usage.
-        This is recommended for handles that will be used by libuv,
-        and not usually recommended otherwise.
-
-    Equivalent to :man:`socketpair(2)` with a domain of AF_UNIX.

-    Sets the specified thread's affinity to cpumask, which is specified in
-    bytes. Optionally returning the previous affinity setting in oldmask.
-    On Unix, uses :man:`pthread_getaffinity_np(3)` to get the affinity setting

-       absolute system time at which the wait expires. If the current system clock time
-       passes the absolute time calculated before the condition is signaled, an ETIMEDOUT
-       error results. After the wait begins, the wait time is not affected by changes
-       to the system clock.

-.. _threadpool:
-
-Thread pool work scheduling
-===========================
-
-libuv provides a threadpool which can be used to run user code and get notified
-in the loop thread. This thread pool is internally used to run all file system
-operations, as well as getaddrinfo and getnameinfo requests.
-
-Its default size is 4, but it can be changed at startup time by setting the
-``UV_THREADPOOL_SIZE`` environment variable to any value (the absolute maximum
-is 1024).
-
-.. versionchanged:: 1.30.0 the maximum UV_THREADPOOL_SIZE allowed was increased from 128 to 1024.
-
-.. versionchanged:: 1.45.0 threads now have an 8 MB stack instead of the
-   (sometimes too low) platform default.
-
-The threadpool is global and shared across all event loops. When a particular
-function makes use of the threadpool (i.e. when using :c:func:`uv_queue_work`)
-libuv preallocates and initializes the maximum number of threads allowed by
-``UV_THREADPOOL_SIZE``. This causes a relatively minor memory overhead
-(~1MB for 128 threads) but increases the performance of threading at runtime.
-
-.. note::
-    Note that even though a global thread pool which is shared across all events
-    loops is used, the functions are not thread safe.
-

-
-    Initialize the handle.
-
-.. c:function:: int uv_timer_start(uv_timer_t* handle, uv_timer_cb cb, uint64_t timeout, uint64_t repeat)
-
-    Start the timer. `timeout` and `repeat` are in milliseconds.
-
-    If `timeout` is zero, the callback fires on the next event loop iteration.
-    If `repeat` is non-zero, the callback fires first after `timeout`
-    milliseconds and then repeatedly after `repeat` milliseconds.
-
-    .. note::
-        Does not update the event loop's concept of "now". See :c:func:`uv_update_time` for more information.

-
-    Stop the timer, the callback will not be called anymore.
-
-.. c:function:: int uv_timer_again(uv_timer_t* handle)

-    Stop the timer, and if it is repeating restart it using the repeat value
-    as the timeout. If the timer has never been started before it returns
-    UV_EINVAL.
-
-.. c:function:: void uv_timer_set_repeat(uv_timer_t* handle, uint64_t repeat)

-    duration, and will follow normal timer semantics in the case of a
-    time-slice overrun.
-
-    For example, if a 50ms repeating timer first runs for 17ms, it will be
-    scheduled to run again 33ms later. If other tasks consume more than the
-    33ms following the first timer callback, then the callback will run as soon
-    as possible.
-
-    .. note::
-        If the repeat value is set from a timer callback it does not immediately take effect.
-        If the timer was non-repeating before, it will have been stopped. If it was repeating,

-.. c:function:: int uv_udp_send(uv_udp_send_t* req, uv_udp_t* handle, const uv_buf_t bufs[], unsigned int nbufs, const struct sockaddr* addr, uv_udp_send_cb send_cb)
-
-    Send data over the UDP socket. If the socket has not previously been bound
-    with :c:func:`uv_udp_bind` it will be bound to 0.0.0.0
-    (the "all interfaces" IPv4 address) and a random port number.
-
-    On Windows if the `addr` is initialized to point to an unspecified address
-    (``0.0.0.0`` or ``::``) it will be changed to point to ``localhost``.
-    This is done to match the behavior of Linux systems.
-
-    For connected UDP handles, `addr` must be set to `NULL`, otherwise it will
-    return `UV_EISCONN` error.
-
-    For connectionless UDP handles, `addr` cannot be `NULL`, otherwise it will
-    return `UV_EDESTADDRREQ` error.
-
-    :param req: UDP request handle. Need not be initialized.

-        address and port of the remote peer.
-
-    :param send_cb: Callback to invoke when the data has been sent out.
-
-    :returns: 0 on success, or an error code < 0 on failure.
-
-    .. versionchanged:: 1.19.0 added ``0.0.0.0`` and ``::`` to ``localhost``
-        mapping
-
-    .. versionchanged:: 1.27.0 added support for connected sockets
-
-.. c:function:: int uv_udp_try_send(uv_udp_t* handle, const uv_buf_t bufs[], unsigned int nbufs, const struct sockaddr* addr)
-
-    Same as :c:func:`uv_udp_send`, but won't queue a send request if it can't
-    be completed immediately.
-
-    For connected UDP handles, `addr` must be set to `NULL`, otherwise it will
-    return `UV_EISCONN` error.
-
-    For connectionless UDP handles, `addr` cannot be `NULL`, otherwise it will
-    return `UV_EDESTADDRREQ` error.
-
-    :returns: >= 0: number of bytes sent (it matches the given buffer size).
-        < 0: negative error code (``UV_EAGAIN`` is returned when the message
-        can't be sent immediately).
-
-    .. versionchanged:: 1.27.0 added support for connected sockets
-
-.. c:function:: int uv_udp_recv_start(uv_udp_t* handle, uv_alloc_cb alloc_cb, uv_udp_recv_cb recv_cb)
-
-    Prepare for receiving data. If the socket has not previously been bound
-    with :c:func:`uv_udp_bind` it is bound to 0.0.0.0 (the "all interfaces"
-    IPv4 address) and a random port number.
-
-    :param handle: UDP handle. Should have been initialized with
-        :c:func:`uv_udp_init`.
-
-    :param alloc_cb: Callback to invoke when temporary storage is needed.
-
-    :param recv_cb: Callback to invoke with received data.
-
-    :returns: 0 on success, or an error code < 0 on failure.
-
-    .. note::
-        When using :man:`recvmmsg(2)`, the number of messages received at a time is limited
-        by the number of max size dgrams that will fit into the buffer allocated in `alloc_cb`, and
-        `suggested_size` in `alloc_cb` for udp_recv is always set to the size of 1 max size dgram.
-
-    .. versionchanged:: 1.35.0 added support for :man:`recvmmsg(2)` on supported platforms).
-                        The use of this feature requires a buffer larger than
-                        2 * 64KB to be passed to `alloc_cb`.
-    .. versionchanged:: 1.37.0 :man:`recvmmsg(2)` support is no longer enabled implicitly,
-                        it must be explicitly requested by passing the `UV_UDP_RECVMMSG` flag to
-                        :c:func:`uv_udp_init_ex`.
-    .. versionchanged:: 1.39.0 :c:func:`uv_udp_using_recvmmsg` can be used in `alloc_cb` to
-                        determine if a buffer sized for use with :man:`recvmmsg(2)` should be
-                        allocated for the current handle/platform.
-
-.. c:function:: int uv_udp_using_recvmmsg(uv_udp_t* handle)
-
-    Returns 1 if the UDP handle was created with the `UV_UDP_RECVMMSG` flag
-    and the platform supports :man:`recvmmsg(2)`, 0 otherwise.
-
-    .. versionadded:: 1.39.0
-
-.. c:function:: int uv_udp_recv_stop(uv_udp_t* handle)
-
-    Stop listening for incoming datagrams.
-
-    :param handle: UDP handle. Should have been initialized with
-        :c:func:`uv_udp_init`.
-
-    :returns: 0 on success, or an error code < 0 on failure.
-
-.. c:function:: size_t uv_udp_get_send_queue_size(const uv_udp_t* handle)
-
-    Returns `handle->send_queue_size`.
-
-    .. versionadded:: 1.19.0
-
-.. c:function:: size_t uv_udp_get_send_queue_count(const uv_udp_t* handle)
-
-    Returns `handle->send_queue_count`.
-
-    .. versionadded:: 1.19.0
-
-.. seealso:: The :c:type:`uv_handle_t` API functions also apply.

-Version-checking macros and functions
-=====================================
-
-Starting with version 1.0.0 libuv follows the `semantic versioning`_
-scheme. This means that new APIs can be introduced throughout the lifetime of
-a major release. In this section you'll find all macros and functions that
-will allow you to write or compile code conditionally, in order to work with
-multiple libuv versions.
-
-.. _semantic versioning: https://semver.org
-
-
-Macros
-------
-
-.. c:macro:: UV_VERSION_MAJOR
-
-    libuv version's major number.
-
-.. c:macro:: UV_VERSION_MINOR
-
-    libuv version's minor number.
-
-.. c:macro:: UV_VERSION_PATCH
-
-    libuv version's patch number.
-
-.. c:macro:: UV_VERSION_IS_RELEASE
-
-    Set to 1 to indicate a release version of libuv, 0 for a development
-    snapshot.
-
-.. c:macro:: UV_VERSION_SUFFIX
-
-    libuv version suffix. Certain development releases such as Release Candidates
-    might have a suffix such as "rc".
-
-.. c:macro:: UV_VERSION_HEX
-
-    Returns the libuv version packed into a single integer. 8 bits are used for
-    each component, with the patch number stored in the 8 least significant
-    bits. E.g. for libuv 1.2.3 this would be 0x010203.
-
-    .. versionadded:: 1.7.0
-
-
-Functions
----------
-
-.. c:function:: unsigned int uv_version(void)
-
-    Returns :c:macro:`UV_VERSION_HEX`.
-
-.. c:function:: const char* uv_version_string(void)
-
-    Returns the libuv version number as a string. For non-release versions the
-    version suffix is included.

- * This file defines data structures for different types of trees:
- * splay trees and red-black trees.
- *
- * A splay tree is a self-organizing data structure.  Every operation
- * on the tree causes a splay to happen.  The splay moves the requested
- * node to the root of the tree and partly rebalances it.
- *
- * This has the benefit that request locality causes faster lookups as
- * the requested nodes move to the top of the tree.  On the other hand,
- * every lookup causes memory writes.
- *
- * The Balance Theorem bounds the total access time for m operations
- * and n inserts on an initially empty tree as O((m + n)lg n).  The
- * amortized cost for a sequence of m accesses to a splay tree is O(lg n);
- *
- * A red-black tree is a binary search tree with the node color as an
- * extra attribute.  It fulfills a set of conditions:
- *  - every search path from the root to a leaf consists of the
- *    same number of black nodes,
- *  - each red node (except for the root) has a black parent,
- *  - each leaf node is black.
- *
- * Every operation on a red-black tree is bounded as O(lg n).
- * The maximum height of a red-black tree is 2lg (n+1).

-# SYNOPSIS
-#
-#   AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
-#
-# DESCRIPTION
-#
-#   This macro figures out how to build C programs using POSIX threads. It
-#   sets the PTHREAD_LIBS output variable to the threads library and linker
-#   flags, and the PTHREAD_CFLAGS output variable to any special C compiler
-#   flags that are needed. (The user can also force certain compiler
-#   flags/libs to be tested by setting these environment variables.)
-#
-#   Also sets PTHREAD_CC to any special C compiler that is needed for
-#   multi-threaded programs (defaults to the value of CC otherwise). (This
-#   is necessary on AIX to use the special cc_r compiler alias.)
-#
-#   NOTE: You are assumed to not only compile your program with these flags,
-#   but also to link with them as well. For example, you might link with
-#   $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
-#
-#   If you are only building threaded programs, you may wish to use these
-#   variables in your default LIBS, CFLAGS, and CC:
-#
-#     LIBS="$PTHREAD_LIBS $LIBS"
-#     CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
-#     CC="$PTHREAD_CC"
-#
-#   In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
-#   has a nonstandard name, this macro defines PTHREAD_CREATE_JOINABLE to
-#   that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
-#
-#   Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the
-#   PTHREAD_PRIO_INHERIT symbol is defined when compiling with
-#   PTHREAD_CFLAGS.
-#
-#   ACTION-IF-FOUND is a list of shell commands to run if a threads library
-#   is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
-#   is not found. If ACTION-IF-FOUND is not specified, the default action
-#   will define HAVE_PTHREAD.
-#
-#   Please let the authors know if this macro fails on any platform, or if
-#   you have any other suggestions or comments. This macro was based on work
-#   by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
-#   from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
-#   Alejandro Forero Cuervo to the autoconf macro repository. We are also
-#   grateful for the helpful feedback of numerous users.

-   *
-   * 2. Write errors are always reported. Write errors are bad because they
-   *    mean data loss: we've read data but now we can't write it out.
-   *
-   * We try to use pread() and fall back to regular read() if the source fd
-   * doesn't support positional reads, for example when it's a pipe fd.
-   *
-   * If we get EAGAIN when writing to the target fd, we poll() on it until
-   * it becomes writable again.
-   *
-   * FIXME: If we get a write error when use_pread==1, it should be safe to
-   *        return the number of sent bytes instead of an error because pread()
-   *        is, in theory, idempotent. However, special files in /dev or /proc
-   *        may support pread() but not necessarily return the same data on
-   *        successive reads.
-   *

- * Predefined stubs for pseudocode:
- *   1. sodisconnect: The function to perform the real udp disconnect
- *   2. pru_connect: The function to perform the real udp connect
- *   3. so: The kernel object match with socket fd
- *   4. addr: The sockaddr parameter from user space
- *
- * BSDs:
- *   if(sodisconnect(so) == 0) { // udp disconnect succeed

- *     if (addr->sa_family != so->addr->sa_family) return EAFNOSUPPORT;

- * search_path searches the system path for an executable filename -
- * the windows API doesn't provide this as a standalone function nor as an
- * option to CreateProcess.
- *
- * It tries to return an absolute filename.
- *
- * Furthermore, it tries to follow the semantics that cmd.exe, with this
- * exception that PATHEXT environment variable isn't used. Since CreateProcess
- * can start only .com and .exe files, only those extensions are tried. This
- * behavior equals that of msvcrt's spawn functions.
- *
- * - Do not search the path if the filename already contains a path (either
- *   relative or absolute).
- *
- * - If there's really only a filename, check the current directory for file,
- *   then search all path directories.
- *
- * - If filename specified has *any* extension, search for the file with the
- *   specified extension first.
- *
- * - If the literal filename is not found in a directory, try *appending*
- *   (not replacing) .com first and then .exe.
- *
- * - The path variable may contain relative paths; relative paths are relative
- *   to the cwd.
- *
- * - Directories in path may or may not end with a trailing backslash.
- *
- * - CMD does not trim leading/trailing whitespace from path/pathex entries
- *   nor from the environment variables as a whole.
- *
- * - When cmd.exe cannot read a directory, it will just skip it and go on
- *   searching. However, unlike posix-y systems, it will happily try to run a
- *   file that is not readable/executable; if the spawn fails it will not
- *   continue searching.
- *
- * UNC path support: we are dealing with UNC paths in both the path and the
- * filename. This is a deviation from what cmd.exe does (it does not let you
- * start a program by specifying an UNC path on the command line) but this is
- * really a pointless restriction.

- * mean that it would extend beyond the bottom of the screen buffer -  in that
- * that case it's located as far down as possible.

- * When the user writes a long text or many newlines, such that the output
- * reaches beyond the bottom of the virtual window, the virtual window is

-/* Tests commented out with XXX are ones that are failing on Linux */
-
-/*
- * Purpose of this test is to check semantics of starting and stopping
- * prepare, check and idle watchers.
- *
- * - A watcher must be able to safely stop or close itself;
- * - Once a watcher is stopped or closed its callback should never be called.
- * - If a watcher is closed, it is implicitly stopped and its close_cb should
- *   be called exactly once.
- * - A watcher can safely start and stop other watchers of the same type.
- * - Prepare and check watchers are called once per event loop iterations.
- * - All active idle watchers are queued when the event loop has no more work
- *   to do. This is done repeatedly until all idle watchers are inactive.
- * - If a watcher starts another watcher of the same type its callback is not
- *   immediately queued. For check and prepare watchers, that means that if
- *   a watcher makes another of the same type active, it'll not be called until
- *   the next event loop iteration. For idle. watchers this means that the
- *   newly activated idle watcher might not be queued immediately.
- * - Prepare, check, idle watchers keep the event loop alive even when they're
- *   not active.
- *
- * This is what the test globally does:
- *
- * - prepare_1 is always active and counts event loop iterations. It also
- *   creates and starts prepare_2 every other iteration. Finally it verifies
- *   that no idle watchers are active before polling.
- * - prepare_2 is started by prepare_1 every other iteration. It immediately
- *   stops itself. It verifies that a watcher is not queued immediately
- *   if created by another watcher of the same type.
- * - There's a check watcher that stops the event loop after a certain number
- *   of iterations. It starts a varying number of idle_1 watchers.
- * - Idle_1 watchers stop themselves after being called a few times. All idle_1
- *   watchers try to start the idle_2 watcher if it is not already started or
- *   awaiting its close callback.
- * - The idle_2 watcher always exists but immediately closes itself after
- *   being started by a check_1 watcher. It verifies that a watcher is
- *   implicitly stopped when closed, and that a watcher can close itself
- *   safely.
- * - There is a repeating timer. It does not keep the event loop alive
- *   (ev_unref) but makes sure that the loop keeps polling the system for
- *   events.

- * The idea behind the test is as follows.
- * Certain handle types are stored in a queue internally.
- * Extra care should be taken for removal of a handle from the queue while iterating over the queue.
- * (i.e., uv__queue_remove() called within uv__queue_foreach())
- * This usually happens when someone closes or stops a handle from within its callback.
- * So we need to check that we haven't screwed the queue on close/stop.
- * To do so we do the following (for each handle type):
- *  1. Create and start 3 handles (#0, #1, and #2).
- *
- *     The queue after the start() calls:
- *     ..=> [queue head] <=> [handle] <=> [handle #1] <=> [handle] <=..
- *
- *  2. Trigger handles to fire (for uv_idle_t, uv_prepare_t, and uv_check_t there is nothing to do).
- *
- *  3. In the callback for the first-executed handle (#0 or #2 depending on handle type)
- *     stop the handle and the next one (#1).
- *     (for uv_idle_t, uv_prepare_t, and uv_check_t callbacks are executed in the reverse order as they are start()'ed,
- *     so callback for handle #2 will be called first)
- *
- *     The queue after the stop() calls:
- *                                correct foreach "next"  |
- *                                                       \/
- *     ..=> [queue head] <==============================> [handle] <=..
- *          [          ] <-  [handle] <=> [handle #1]  -> [      ]
- *                                       /\
- *                  wrong foreach "next"  |
- *
- *  4. The callback for handle #1 shouldn't be called because the handle #1 is stopped in the previous step.
- *     However, if uv__queue_remove() is not handled properly within uv__queue_foreach(), the callback _will_
- *     be called.

+# CONTRIBUTING
+
+The libuv project welcomes new contributors. This document will guide you
+through the process.
+
+
+### FORK
+
+Fork the project [on GitHub](https://github.com/libuv/libuv) and check out
+your copy.
+
+```
+$ git clone https://github.com/username/libuv.git
+$ cd libuv
+$ git remote add upstream https://github.com/libuv/libuv.git
+```
+
+Now decide if you want your feature or bug fix to go into the master branch
+or the stable branch.  As a rule of thumb, bug fixes go into the stable branch
+while new features go into the master branch.
+
+The stable branch is effectively frozen; patches that change the libuv
+API/ABI or affect the run-time behavior of applications get rejected.
+
+In case of doubt, open an issue in the [issue tracker][], post your question
+to the [libuv discussions forum], or message the [libuv mailing list].
+
+Especially do so if you plan to work on something big. Nothing is more
+frustrating than seeing your hard work go to waste because your vision does not
+align with that of the [project maintainers].
+
+
+### BRANCH
+
+Okay, so you have decided on the proper branch.  Create a feature branch
+and start hacking:
+
+```
+$ git checkout -b my-feature-branch -t origin/v1.x
+```
+
+(Where v1.x is the latest stable branch as of this writing.)
+
+### CODE
+
+Please adhere to libuv's code style. In general it follows the conventions from
+the [Google C/C++ style guide]. Some of the key points, as well as some
+additional guidelines, are enumerated below.
+
+* Code that is specific to unix-y platforms should be placed in `src/unix`, and
+  declarations go into `include/uv/unix.h`.
+
+* Source code that is Windows-specific goes into `src/win`, and related
+  publicly exported types, functions and macro declarations should generally
+  be declared in `include/uv/win.h`.
+
+* Names should be descriptive and concise.
+
+* All the symbols and types that libuv makes available publicly should be
+  prefixed with `uv_` (or `UV_` in case of macros).
+
+* Internal, non-static functions should be prefixed with `uv__`.
+
+* Use two spaces and no tabs.
+
+* Lines should be wrapped at 80 characters.
+
+* Ensure that lines have no trailing whitespace, and use unix-style (LF) line
+  endings.
+
+* Use C89-compliant syntax. In other words, variables can only be declared at
+  the top of a scope (function, if/for/while-block).
+
+* When writing comments, use properly constructed sentences, including
+  punctuation.
+
+* When documenting APIs and/or source code, don't make assumptions or make
+  implications about race, gender, religion, political orientation or anything
+  else that isn't relevant to the project.
+
+* Remember that source code usually gets written once and read often: ensure
+  the reader doesn't have to make guesses. Make sure that the purpose and inner
+  logic are either obvious to a reasonably skilled professional, or add a
+  comment that explains it.
+
+
+### COMMIT
+
+Make sure git knows your name and email address:
+
+```
+$ git config --global user.name "J. Random User"
+$ git config --global user.email "j.random.user@example.com"
+```
+
+Writing good commit logs is important.  A commit log should describe what
+changed and why.  Follow these guidelines when writing one:
+
+1. The first line should be 50 characters or less and contain a short
+   description of the change prefixed with the name of the changed
+   subsystem (e.g. "net: add localAddress and localPort to Socket").
+2. Keep the second line blank.
+3. Wrap all other lines at 72 columns.
+
+A good commit log looks like this:
+
+```
+subsystem: explaining the commit in one line
+
+Body of commit message is a few lines of text, explaining things
+in more detail, possibly giving some background about the issue
+being fixed, etc etc.
+
+The body of the commit message can be several paragraphs, and
+please do proper word-wrap and keep columns shorter than about
+72 characters or so. That way `git log` will show things
+nicely even when it is indented.
+```
+
+The header line should be meaningful; it is what other people see when they
+run `git shortlog` or `git log --oneline`.
+
+Check the output of `git log --oneline files_that_you_changed` to find out
+what subsystem (or subsystems) your changes touch.
+
+
+### REBASE
+
+Use `git rebase` (not `git merge`) to sync your work from time to time.
+
+```
+$ git fetch upstream
+$ git rebase upstream/v1.x  # or upstream/master
+```
+
+
+### TEST

+Bug fixes and features should come with tests.  Add your tests in the
+`test/` directory. Each new test needs to be registered in `test/test-list.h`.
+
+If you add a new test file, it needs to be registered in three places:
+- `CMakeLists.txt`: add the file's name to the `uv_test_sources` list.
+- `Makefile.am`: add the file's name to the `test_run_tests_SOURCES` list.
+
+Look at other tests to see how they should be structured (license boilerplate,
+the way entry points are declared, etc.).
+
+Check README.md file to find out how to run the test suite and make sure that
+there are no test regressions.
+
+### PUSH
+
+```
+$ git push origin my-feature-branch
+```
+
+Go to https://github.com/username/libuv and select your feature branch.  Click
+the 'Pull Request' button and fill out the form.
+
+Pull requests are usually reviewed within a few days.  If there are comments
+to address, apply your changes in a separate commit and push that to your
+feature branch.  Post a comment in the pull request afterwards; GitHub does
+not send out notifications when you add commits.

+Attribution 4.0 International Public License ("Public License"). To the
+extent this Public License may be interpreted as a contract, You are

+     and in which the Licensed Material is translated, altered,
+     arranged, transformed, or otherwise modified in a manner requiring
+     permission under the Copyright and Similar Rights held by the
+     Licensor. For purposes of this Public License, where the Licensed

+     synched in timed relation with a moving image.
+
+  b. Adapter's License means the license You apply to Your Copyright
+     and Similar Rights in Your contributions to Adapted Material in
+     accordance with the terms and conditions of this Public License.

+     Rights.
+
+  d. Effective Technological Measures means those measures that, in the
+     absence of proper authority, may not be circumvented under laws

+     agreements.
+
+  e. Exceptions and Limitations means fair use, fair dealing, and/or
+     any other exception or limitation to Copyright and Similar Rights
+     that applies to Your use of the Licensed Material.
+
+  f. Licensed Material means the artistic or literary work, database,
+     or other material to which the Licensor applied this Public
+     License.
+
+  g. Licensed Rights means the rights granted to You subject to the

+     all Copyright and Similar Rights that apply to Your use of the
+     Licensed Material and that the Licensor has authority to license.
+
+  h. Licensor means the individual(s) or entity(ies) granting rights
+     under this Public License.
+
+  i. Share means to provide material to the public by any means or
+     process that requires permission under the Licensed Rights, such
+     as reproduction, public display, public performance, distribution,
+     dissemination, communication, or importation, and to make material

+     the Council of 11 March 1996 on the legal protection of databases,
+     as amended and/or succeeded, as well as other essentially
+     equivalent rights anywhere in the world.
+
+  k. You means the individual or entity exercising the Licensed Rights
+     under this Public License. Your has a corresponding meaning.
+
+
+Section 2 -- Scope.
+
+  a. License grant.
+
+       1. Subject to the terms and conditions of this Public License,
+          the Licensor hereby grants You a worldwide, royalty-free,
+          non-sublicensable, non-exclusive, irrevocable license to
+          exercise the Licensed Rights in the Licensed Material to:
+
+            a. reproduce and Share the Licensed Material, in whole or
+               in part; and
+
+            b. produce, reproduce, and Share Adapted Material.
+
+       2. Exceptions and Limitations. For the avoidance of doubt, where
+          Exceptions and Limitations apply to Your use, this Public
+          License does not apply, and You do not need to comply with
+          its terms and conditions.
+
+       3. Term. The term of this Public License is specified in Section
+          6(a).
+
+       4. Media and formats; technical modifications allowed. The
+          Licensor authorizes You to exercise the Licensed Rights in
+          all media and formats whether now known or hereafter created,
+          and to make technical modifications necessary to do so. The
+          Licensor waives and/or agrees not to assert any right or
+          authority to forbid You from making technical modifications
+          necessary to exercise the Licensed Rights, including
+          technical modifications necessary to circumvent Effective
+          Technological Measures. For purposes of this Public License,
+          simply making modifications authorized by this Section 2(a)
+          (4) never produces Adapted Material.
+
+       5. Downstream recipients.
+
+            a. Offer from the Licensor -- Licensed Material. Every
+               recipient of the Licensed Material automatically
+               receives an offer from the Licensor to exercise the
+               Licensed Rights under the terms and conditions of this
+               Public License.
+
+            b. No downstream restrictions. You may not offer or impose
+               any additional or different terms or conditions on, or
+               apply any Effective Technological Measures to, the
+               Licensed Material if doing so restricts exercise of the
+               Licensed Rights by any recipient of the Licensed
+               Material.
+
+       6. No endorsement. Nothing in this Public License constitutes or
+          may be construed as permission to assert or imply that You
+          are, or that Your use of the Licensed Material is, connected
+          with, or sponsored, endorsed, or granted official status by,
+          the Licensor or others designated to receive attribution as
+          provided in Section 3(a)(1)(A)(i).
+
+  b. Other rights.
+
+       1. Moral rights, such as the right of integrity, are not
+          licensed under this Public License, nor are publicity,
+          privacy, and/or other similar personality rights; however, to
+          the extent possible, the Licensor waives and/or agrees not to
+          assert any such rights held by the Licensor to the limited
+          extent necessary to allow You to exercise the Licensed
+          Rights, but not otherwise.
+
+       2. Patent and trademark rights are not licensed under this
+          Public License.
+
+       3. To the extent possible, the Licensor waives any right to
+          collect royalties from You for the exercise of the Licensed
+          Rights, whether directly or through a collecting society
+          under any voluntary or waivable statutory or compulsory
+          licensing scheme. In all other cases the Licensor expressly
+          reserves any right to collect such royalties.
+
+
+Section 3 -- License Conditions.
+
+Your exercise of the Licensed Rights is expressly made subject to the
+following conditions.
+
+  a. Attribution.
+
+       1. If You Share the Licensed Material (including in modified
+          form), You must:
+
+            a. retain the following if it is supplied by the Licensor
+               with the Licensed Material:
+
+                 i. identification of the creator(s) of the Licensed
+                    Material and any others designated to receive
+                    attribution, in any reasonable manner requested by
+                    the Licensor (including by pseudonym if
+                    designated);
+
+                ii. a copyright notice;
+
+               iii. a notice that refers to this Public License;
+
+                iv. a notice that refers to the disclaimer of
+                    warranties;
+
+                 v. a URI or hyperlink to the Licensed Material to the
+                    extent reasonably practicable;
+
+            b. indicate if You modified the Licensed Material and
+               retain an indication of any previous modifications; and
+
+            c. indicate the Licensed Material is licensed under this
+               Public License, and include the text of, or the URI or
+               hyperlink to, this Public License.
+
+       2. You may satisfy the conditions in Section 3(a)(1) in any
+          reasonable manner based on the medium, means, and context in
+          which You Share the Licensed Material. For example, it may be
+          reasonable to satisfy the conditions by providing a URI or
+          hyperlink to a resource that includes the required
+          information.
+
+       3. If requested by the Licensor, You must remove any of the
+          information required by Section 3(a)(1)(A) to the extent
+          reasonably practicable.
+
+       4. If You Share Adapted Material You produce, the Adapter's
+          License You apply must not prevent recipients of the Adapted
+          Material from complying with this Public License.
+
+
+Section 4 -- Sui Generis Database Rights.
+
+Where the Licensed Rights include Sui Generis Database Rights that
+apply to Your use of the Licensed Material:
+
+  a. for the avoidance of doubt, Section 2(a)(1) grants You the right
+     to extract, reuse, reproduce, and Share all or a substantial
+     portion of the contents of the database;
+
+  b. if You include all or a substantial portion of the database
+     contents in a database in which You have Sui Generis Database
+     Rights, then the database in which You have Sui Generis Database
+     Rights (but not its individual contents) is Adapted Material; and
+
+  c. You must comply with the conditions in Section 3(a) if You Share
+     all or a substantial portion of the contents of the database.
+
+For the avoidance of doubt, this Section 4 supplements and does not
+replace Your obligations under this Public License where the Licensed
+Rights include other Copyright and Similar Rights.
+
+
+Section 5 -- Disclaimer of Warranties and Limitation of Liability.
+
+  a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE
+     EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS
+     AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF
+     ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS,
+     IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION,
+     WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR
+     PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS,
+     ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT
+     KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT
+     ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.
+
+  b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE
+     TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION,
+     NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT,
+     INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES,
+     COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR
+     USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN
+     ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR
+     DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR
+     IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.
+
+  c. The disclaimer of warranties and limitation of liability provided
+     above shall be interpreted in a manner that, to the extent
+     possible, most closely approximates an absolute disclaimer and
+     waiver of all liability.
+
+
+Section 6 -- Term and Termination.
+
+  a. This Public License applies for the term of the Copyright and
+     Similar Rights licensed here. However, if You fail to comply with
+     this Public License, then Your rights under this Public License
+     terminate automatically.
+
+  b. Where Your right to use the Licensed Material has terminated under
+     Section 6(a), it reinstates:
+
+       1. automatically as of the date the violation is cured, provided
+          it is cured within 30 days of Your discovery of the
+          violation; or
+
+       2. upon express reinstatement by the Licensor.
+
+     For the avoidance of doubt, this Section 6(b) does not affect any
+     right the Licensor may have to seek remedies for Your violations
+     of this Public License.
+
+  c. For the avoidance of doubt, the Licensor may also offer the
+     Licensed Material under separate terms or conditions or stop
+     distributing the Licensed Material at any time; however, doing so
+     will not terminate this Public License.
+
+  d. Sections 1, 5, 6, 7, and 8 survive termination of this Public
+     License.
+
+
+Section 7 -- Other Terms and Conditions.
+
+  a. The Licensor shall not be bound by any additional or different
+     terms or conditions communicated by You unless expressly agreed.
+
+  b. Any arrangements, understandings, or agreements regarding the
+     Licensed Material not stated herein are separate from and
+     independent of the terms and conditions of this Public License.
+
+
+Section 8 -- Interpretation.
+
+  a. For the avoidance of doubt, this Public License does not, and
+     shall not be interpreted to, reduce, limit, restrict, or impose
+     conditions on any use of the Licensed Material that could lawfully
+     be made without permission under this Public License.

+## Storing a maintainer key in Git
+
+It's quite handy to store a maintainer's signature as a git blob, and have
+that object tagged and signed with such key.
+
+Export your public key:
+
+    $ gpg --armor --export saghul@gmail.com > saghul.asc
+
+Store it as a blob on the repo:
+
+    $ git hash-object -w saghul.asc
+
+The previous command returns a hash, copy it. For the sake of this explanation,
+we'll assume it's 'abcd1234'. Storing the blob in git is not enough, it could
+be garbage collected since nothing references it, so we'll create a tag for it:
+
+    $ git tag -s pubkey-saghul abcd1234
+
+Commit the changes and push:
+
+    $ git push origin pubkey-saghul

+
+## Overview
+
+libuv is a multi-platform support library with a focus on asynchronous I/O. It
+was primarily developed for use by [Node.js][], but it's also
+used by [Luvit](http://luvit.io/), [Julia](http://julialang.org/),
+[uvloop](https://github.com/MagicStack/uvloop), and [others](https://github.com/libuv/libuv/blob/v1.x/LINKS.md).
+
+## Feature highlights
+
+ * Full-featured event loop backed by epoll, kqueue, IOCP, event ports.
+
+ * Asynchronous TCP and UDP sockets
+
+ * Asynchronous DNS resolution
+
+ * Asynchronous file and file system operations
+
+ * File system events
+
+ * ANSI escape code controlled TTY
+
+ * IPC with socket sharing, using Unix domain sockets or named pipes (Windows)
+
+ * Child processes
+
+ * Thread pool
+
+ * Signal handling
+
+ * High resolution clock
+
+ * Threading and synchronization primitives
+
+## Versioning
+
+Starting with version 1.0.0 libuv follows the [semantic versioning](http://semver.org/)
+scheme. The API change and backwards compatibility rules are those indicated by
+SemVer. libuv will keep a stable ABI across major releases.
+
+The ABI/API changes can be tracked [here](http://abi-laboratory.pro/tracker/timeline/libuv/).
+
+## Licensing
+
+libuv is licensed under the MIT license. Check the [LICENSE](LICENSE) and
+[LICENSE-extra](LICENSE-extra) files.

+
+## Documentation
+
+### Official documentation
+
+Located in the docs/ subdirectory. It uses the [Sphinx](http://sphinx-doc.org/)
+framework, which makes it possible to build the documentation in multiple
+formats.
+
+Show different supported building options:
+
+```bash
+$ make help
+```
+
+Build documentation as HTML:
+
+```bash
+$ make html
+```
+
+Build documentation as HTML and live reload it when it changes (this requires
+sphinx-autobuild to be installed and is only supported on Unix):
+
+```bash
+$ make livehtml
+```
+
+Build documentation as man pages:
+
+```bash
+$ make man
+```
+
+Build documentation as ePub:
+
+```bash
+$ make epub
+```
+
+NOTE: Windows users need to use make.bat instead of plain 'make'.
+
+Documentation can be browsed online [here](http://docs.libuv.org).
+
+The [tests and benchmarks](https://github.com/libuv/libuv/tree/master/test)
+also serve as API specification and usage examples.
+
+### Other resources
+
+ * [LXJS 2012 talk](http://www.youtube.com/watch?v=nGn60vDSxQ4)
+   &mdash; High-level introductory talk about libuv.
+ * [libuv-dox](https://github.com/thlorenz/libuv-dox)
+   &mdash; Documenting types and methods of libuv, mostly by reading uv.h.
+ * [learnuv](https://github.com/thlorenz/learnuv)
+   &mdash; Learn uv for fun and profit, a self guided workshop to libuv.
+
+These resources are not handled by libuv maintainers and might be out of
+date. Please verify it before opening new issues.
+
+## Downloading
+
+libuv can be downloaded either from the
+[GitHub repository](https://github.com/libuv/libuv)
+or from the [downloads site](http://dist.libuv.org/dist/).
+
+Before verifying the git tags or signature files, importing the relevant keys
+is necessary. Key IDs are listed in the
+[MAINTAINERS](https://github.com/libuv/libuv/blob/master/MAINTAINERS.md)
+file, but are also available as git blob objects for easier use.
+
+Importing a key the usual way:
+
+```bash
+$ gpg --keyserver pool.sks-keyservers.net --recv-keys AE9BC059
+```
+
+Importing a key from a git blob object:
+
+```bash
+$ git show pubkey-saghul | gpg --import
+```
+
+### Verifying releases
+
+Git tags are signed with the developer's key, they can be verified as follows:
+
+```bash
+$ git verify-tag v1.6.1
+```
+
+Starting with libuv 1.7.0, the tarballs stored in the
+[downloads site](http://dist.libuv.org/dist/) are signed and an accompanying
+signature file sit alongside each. Once both the release tarball and the
+signature file are downloaded, the file can be verified as follows:
+
+```bash
+$ gpg --verify libuv-1.7.0.tar.gz.sign
+```
+
+## Build Instructions
+
+For UNIX-like platforms, including macOS, there are two build methods:
+autotools or [CMake][].
+
+For Windows, [CMake][] is the only supported build method and has the
+following prerequisites:
+
+<details>
+
+* One of:
+  * [Visual C++ Build Tools][]
+  * [Visual Studio 2015 Update 3][], all editions
+    including the Community edition (remember to select
+    "Common Tools for Visual C++ 2015" feature during installation).
+  * [Visual Studio 2017][], any edition (including the Build Tools SKU).
+    **Required Components:** "MSbuild", "VC++ 2017 v141 toolset" and one of the
+    Windows SDKs (10 or 8.1).
+* Basic Unix tools required for some tests,
+  [Git for Windows][] includes Git Bash
+  and tools which can be included in the global `PATH`.
+
+</details>
+
+To build with autotools:
+
+```bash
+$ sh autogen.sh
+$ ./configure
+$ make
+$ make check
+$ make install
+```
+
+To build with [CMake][]:
+
+```bash
+$ mkdir -p build
+
+$ (cd build && cmake .. -DBUILD_TESTING=ON) # generate project with tests
+$ cmake --build build                       # add `-j <n>` with cmake >= 3.12
+
+# Run tests:
+$ (cd build && ctest -C Debug --output-on-failure)
+
+# Or manually run tests:
+$ build/uv_run_tests                        # shared library build
+$ build/uv_run_tests_a                      # static library build
+```
+
+To cross-compile with [CMake][] (unsupported but generally works):
+
+```bash
+$ cmake ../..                 \
+  -DCMAKE_SYSTEM_NAME=Windows \
+  -DCMAKE_SYSTEM_VERSION=6.1  \
+  -DCMAKE_C_COMPILER=i686-w64-mingw32-gcc
+```
+
+### Install with Homebrew
+
+```bash
+$ brew install --HEAD libuv
+```
+
+Note to OS X users:
+
+Make sure that you specify the architecture you wish to build for in the
+"ARCHS" flag. You can specify more than one by delimiting with a space
+(e.g. "x86_64 i386").
+
+### Install with vcpkg
+
+```bash
+$ git clone https://github.com/microsoft/vcpkg.git
+$ ./bootstrap-vcpkg.bat # for powershell
+$ ./bootstrap-vcpkg.sh # for bash
+$ ./vcpkg install libuv
+```
+
+### Running tests
+
+Some tests are timing sensitive. Relaxing test timeouts may be necessary
+on slow or overloaded machines:
+
+```bash
+$ env UV_TEST_TIMEOUT_MULTIPLIER=2 build/uv_run_tests # 10s instead of 5s
+```
+
+#### Run one test
+
+The list of all tests is in `test/test-list.h`.
+
+This invocation will cause the test driver to fork and execute `TEST_NAME` in
+a child process:
+
+```bash
+$ build/uv_run_tests_a TEST_NAME
+```
+
+This invocation will cause the test driver to execute the test in
+the same process:
+
+```bash
+$ build/uv_run_tests_a TEST_NAME TEST_NAME
+```
+
+#### Debugging tools
+
+When running the test from within the test driver process
+(`build/uv_run_tests_a TEST_NAME TEST_NAME`), tools like gdb and valgrind
+work normally.
+
+When running the test from a child of the test driver process
+(`build/uv_run_tests_a TEST_NAME`), use these tools in a fork-aware manner.
+
+##### Fork-aware gdb
+
+Use the [follow-fork-mode](https://sourceware.org/gdb/onlinedocs/gdb/Forks.html) setting:
+
+```
+$ gdb --args build/uv_run_tests_a TEST_NAME
+
+(gdb) set follow-fork-mode child
+...
+```
+
+##### Fork-aware valgrind
+
+Use the `--trace-children=yes` parameter:
+
+```bash
+$ valgrind --trace-children=yes -v --tool=memcheck --leak-check=full --track-origins=yes --leak-resolution=high --show-reachable=yes --log-file=memcheck-%p.log build/uv_run_tests_a TEST_NAME
+```
+
+### Running benchmarks
+
+See the section on running tests.
+The benchmark driver is `./uv_run_benchmarks_a` and the benchmarks are
+listed in `test/benchmark-list.h`.
+
+## Supported Platforms
+
+Check the [SUPPORTED_PLATFORMS file](SUPPORTED_PLATFORMS.md).
+
+### `-fno-strict-aliasing`
+
+It is recommended to turn on the `-fno-strict-aliasing` compiler flag in
+projects that use libuv. The use of ad hoc "inheritance" in the libuv API
+may not be safe in the presence of compiler optimizations that depend on
+strict aliasing.
+
+MSVC does not have an equivalent flag but it also does not appear to need it
+at the time of writing (December 2019.)
+
+### AIX Notes
+
+AIX compilation using IBM XL C/C++ requires version 12.1 or greater.
+
+AIX support for filesystem events requires the non-default IBM `bos.ahafs`
+package to be installed.  This package provides the AIX Event Infrastructure
+that is detected by `autoconf`.
+[IBM documentation](http://www.ibm.com/developerworks/aix/library/au-aix_event_infrastructure/)
+describes the package in more detail.
+
+### z/OS Notes
+
+z/OS compilation requires [ZOSLIB](https://github.com/ibmruntimes/zoslib) to be installed. When building with [CMake][], use the flag `-DZOSLIB_DIR` to specify the path to [ZOSLIB](https://github.com/ibmruntimes/zoslib):
+
+```bash
+$ (cd build && cmake .. -DBUILD_TESTING=ON -DZOSLIB_DIR=/path/to/zoslib)
+$ cmake --build build
+```
+
+z/OS creates System V semaphores and message queues. These persist on the system
+after the process terminates unless the event loop is closed.
+
+Use the `ipcrm` command to manually clear up System V resources.

+# Supported platforms
+
+|  System | Support type | Supported versions | Notes |
+|---|---|---|---|
+| GNU/Linux | Tier 1 | Linux >= 3.10 with glibc >= 2.17 | |
+| macOS | Tier 1 | macOS >= 11 | Currently supported macOS releases |
+| Windows | Tier 1 | >= Windows 8 | VS 2015 and later are supported |
+| FreeBSD | Tier 2 | >= 12 | |
+| AIX | Tier 2 | >= 6 | Maintainers: @libuv/aix |
+| IBM i | Tier 2 | >= IBM i 7.2 | Maintainers: @libuv/ibmi |
+| z/OS | Tier 2 | >= V2R2 | Maintainers: @libuv/zos |
+| Linux with musl | Tier 2 | musl >= 1.0 | |
+| Android | Tier 3 | NDK >= r15b | Android 7.0, `-DANDROID_PLATFORM=android-24` |
+| MinGW | Tier 3 | MinGW32 and MinGW-w64 | |
+| SunOS | Tier 3 | Solaris 121 and later | |
+| Other | Tier 3 | N/A | |
+
+## Support types
+
+* **Tier 1**: Officially supported and tested with CI. Any contributed patch
+  MUST NOT break such systems. These are supported by @libuv/collaborators.
+
+* **Tier 2**: Officially supported, but not necessarily tested with CI. These
+  systems are maintained to the best of @libuv/collaborators ability,
+  without being a top priority.
+
+* **Tier 3**: Community maintained. These systems may inadvertently break and the
+  community and interested parties are expected to help with the maintenance.
+
+## Adding support for a new platform
+
+**IMPORTANT**: Before attempting to add support for a new platform please open
+an issue about it for discussion.
+
+### Unix
+
+I/O handling is abstracted by an internal `uv__io_t` handle. The new platform
+will need to implement some of the functions, the prototypes are in
+``src/unix/internal.h``.
+
+If the new platform requires extra fields for any handle structure, create a
+new include file in ``include/`` with the name ``uv-theplatform.h`` and add
+the appropriate defines there.
+
+All functionality related to the new platform must be implemented in its own
+file inside ``src/unix/`` unless it's already done in a common file, in which
+case adding an `ifdef` is fine.
+
+Two build systems are supported: autotools and cmake. Ideally both need to be
+supported, but if one of the two does not support the new platform it can be
+left out.
+
+### Windows
+
+Windows is treated as a single platform, so adding support for a new platform
+would mean adding support for a new version.
+
+Compilation and runtime must succeed for the minimum supported version. If a
+new API is to be used, it must be done optionally, only in supported versions.
+
+### Common
+
+Some common notes when adding support for new platforms:
+
+* Generally libuv tries to avoid compile time checks. Do not add any to the
+  autotools based build system or use version checking macros.
+  Dynamically load functions and symbols if they are not supported by the
+  minimum supported version.

+
+:c:type:`uv_async_t` --- Async handle
+=====================================
+
+Async handles allow the user to "wakeup" the event loop and get a callback
+called from another thread.
+
+
+Data types
+----------
+
+.. c:type:: uv_async_t
+
+    Async handle type.
+
+.. c:type:: void (*uv_async_cb)(uv_async_t* handle)
+
+    Type definition for callback passed to :c:func:`uv_async_init`.
+
+
+Public members
+^^^^^^^^^^^^^^
+
+N/A
+
+.. seealso:: The :c:type:`uv_handle_t` members also apply.
+
+
+API
+---
+
+.. c:function:: int uv_async_init(uv_loop_t* loop, uv_async_t* async, uv_async_cb async_cb)
+
+    Initialize the handle. A NULL callback is allowed.
+
+    :returns: 0 on success, or an error code < 0 on failure.
+
+    .. note::
+        Unlike other handle initialization  functions, it immediately starts the handle.
+
+.. c:function:: int uv_async_send(uv_async_t* async)
+
+    Wake up the event loop and call the async handle's callback.
+
+    :returns: 0 on success, or an error code < 0 on failure.
+
+    .. note::
+        It's safe to call this function from any thread. The callback will be called on the
+        loop thread.
+
+    .. note::
+        :c:func:`uv_async_send` is `async-signal-safe <https://man7.org/linux/man-pages/man7/signal-safety.7.html>`_.
+        It's safe to call this function from a signal handler.
+
+    .. warning::
+        libuv will coalesce calls to :c:func:`uv_async_send`, that is, not every call to it will
+        yield an execution of the callback. For example: if :c:func:`uv_async_send` is called 5
+        times in a row before the callback is called, the callback will only be called once. If
+        :c:func:`uv_async_send` is called again after the callback was called, it will be called
+        again.
+
+.. seealso::
+    The :c:type:`uv_handle_t` API functions also apply.

+
+Design overview
+===============
+
+libuv is cross-platform support library which was originally written for `Node.js`_. It's designed
+around the event-driven asynchronous I/O model.
+
+.. _Node.js: https://nodejs.org
+
+The library provides much more than a simple abstraction over different I/O polling mechanisms:
+'handles' and 'streams' provide a high level abstraction for sockets and other entities;
+cross-platform file I/O and threading functionality is also provided, amongst other things.
+
+Here is a diagram illustrating the different parts that compose libuv and what subsystem they
+relate to:
+
+.. image:: static/architecture.png
+    :scale: 75%
+    :align: center
+
+
+Handles and requests
+^^^^^^^^^^^^^^^^^^^^
+
+libuv provides users with 2 abstractions to work with, in combination with the event loop:
+handles and requests.
+
+Handles represent long-lived objects capable of performing certain operations while active. Some examples:
+
+- A prepare handle gets its callback called once every loop iteration when active.
+- A TCP server handle that gets its connection callback called every time there is a new connection.
+
+Requests represent (typically) short-lived operations. These operations can be performed over a
+handle: write requests are used to write data on a handle; or standalone: getaddrinfo requests
+don't need a handle they run directly on the loop.
+
+
+The I/O loop
+^^^^^^^^^^^^
+
+The I/O (or event) loop is the central part of libuv. It establishes the content for all I/O
+operations, and it's meant to be tied to a single thread. One can run multiple event loops
+as long as each runs in a different thread. The libuv event loop (or any other API involving
+the loop or handles, for that matter) **is not thread-safe** except where stated otherwise.
+
+The event loop follows the rather usual single threaded asynchronous I/O approach: all (network)
+I/O is performed on non-blocking sockets which are polled using the best mechanism available
+on the given platform: epoll on Linux, kqueue on OSX and other BSDs, event ports on SunOS and IOCP
+on Windows. As part of a loop iteration the loop will block waiting for I/O activity on sockets
+which have been added to the poller and callbacks will be fired indicating socket conditions
+(readable, writable hangup) so handles can read, write or perform the desired I/O operation.
+
+In order to better understand how the event loop operates, the following diagram illustrates all
+stages of a loop iteration:
+
+.. image:: static/loop_iteration.png
+    :scale: 75%
+    :align: center
+
+
+#. The loop concept of 'now' is initially set.
+
+#. Due timers are run if the loop was run with ``UV_RUN_DEFAULT``. All active timers scheduled
+   for a time before the loop's concept of *now* get their callbacks called.
+
+#. If the loop is *alive*  an iteration is started, otherwise the loop will exit immediately. So,
+   when is a loop considered to be *alive*? If a loop has active and ref'd handles, active
+   requests or closing handles it's considered to be *alive*.
+
+#. Pending callbacks are called. All I/O callbacks are called right after polling for I/O, for the
+   most part. There are cases, however, in which calling such a callback is deferred for the next
+   loop iteration. If the previous iteration deferred any I/O callback it will be run at this point.
+
+#. Idle handle callbacks are called. Despite the unfortunate name, idle handles are run on every
+   loop iteration, if they are active.
+
+#. Prepare handle callbacks are called. Prepare handles get their callbacks called right before
+   the loop will block for I/O.
+
+#. Poll timeout is calculated. Before blocking for I/O the loop calculates for how long it should
+   block. These are the rules when calculating the timeout:
+
+        * If the loop was run with the ``UV_RUN_NOWAIT`` flag, the timeout is 0.
+        * If the loop is going to be stopped (:c:func:`uv_stop` was called), the timeout is 0.
+        * If there are no active handles or requests, the timeout is 0.
+        * If there are any idle handles active, the timeout is 0.
+        * If there are any handles pending to be closed, the timeout is 0.
+        * If none of the above cases matches, the timeout of the closest timer is taken, or
+          if there are no active timers, infinity.
+
+#. The loop blocks for I/O. At this point the loop will block for I/O for the duration calculated
+   in the previous step. All I/O related handles that were monitoring a given file descriptor
+   for a read or write operation get their callbacks called at this point.
+
+#. Check handle callbacks are called. Check handles get their callbacks called right after the
+   loop has blocked for I/O. Check handles are essentially the counterpart of prepare handles.
+
+#. Close callbacks are called. If a handle was closed by calling :c:func:`uv_close` it will
+   get the close callback called.
+
+#. The loop concept of 'now' is updated.
+
+#. Due timers are run. Note that 'now' is not updated again until the next loop iteration.
+   So if a timer became due while other timers were being processed, it won't be run until
+   the following event loop iteration.
+
+#. Iteration ends. If the loop was run with ``UV_RUN_NOWAIT`` or ``UV_RUN_ONCE`` modes the
+   iteration ends and :c:func:`uv_run` will return. If the loop was run with ``UV_RUN_DEFAULT``
+   it will continue from the start if it's still *alive*, otherwise it will also end.
+
+
+.. important::
+    libuv uses a thread pool to make asynchronous file I/O operations possible, but
+    network I/O is **always** performed in a single thread, each loop's thread.
+
+.. note::
+    While the polling mechanism is different, libuv makes the execution model consistent
+    across Unix systems and Windows.
+
+
+File I/O
+^^^^^^^^
+
+Unlike network I/O, there are no platform-specific file I/O primitives libuv could rely on,
+so the current approach is to run blocking file I/O operations in a thread pool.
+
+For a thorough explanation of the cross-platform file I/O landscape, check out
+`this post <https://blog.libtorrent.org/2012/10/asynchronous-disk-io/>`_.
+
+libuv currently uses a global thread pool on which all loops can queue work. 3 types of
+operations are currently run on this pool:
+
+    * File system operations
+    * DNS functions (getaddrinfo and getnameinfo)
+    * User specified code via :c:func:`uv_queue_work`
+
+.. warning::
+    See the :c:ref:`threadpool` section for more details, but keep in mind the thread pool size
+    is quite limited.

+
+File system operations
+======================
+
+libuv provides a wide variety of cross-platform sync and async file system
+operations. All functions defined in this document take a callback, which is
+allowed to be NULL. If the callback is NULL the request is completed synchronously,
+otherwise it will be performed asynchronously.
+
+All file operations are run on the threadpool. See :ref:`threadpool` for information
+on the threadpool size.
+
+Starting with libuv v1.45.0, some file operations on Linux are handed off to
+`io_uring <https://en.wikipedia.org/wiki/Io_uring>` when possible. Apart from
+a (sometimes significant) increase in throughput there should be no change in
+observable behavior. Libuv reverts to using its threadpool when the necessary
+kernel features are unavailable or unsuitable.
+
+.. note::
+     On Windows `uv_fs_*` functions use utf-8 encoding.

+
+    Equivalent to :man:`open(2)`.
+
+    .. note::
+        On Windows libuv uses `CreateFileW` and thus the file is always opened
+        in binary mode. Because of this the O_BINARY and O_TEXT flags are not
+        supported.
+
+.. c:function:: int uv_fs_read(uv_loop_t* loop, uv_fs_t* req, uv_file file, const uv_buf_t bufs[], unsigned int nbufs, int64_t offset, uv_fs_cb cb)
+
+    Equivalent to :man:`preadv(2)`. If the `offset` argument is `-1`, then
+    the current file offset is used and updated.
+
+    .. warning::
+        On Windows, under non-MSVC environments (e.g. when GCC or Clang is used
+        to build libuv), files opened using ``UV_FS_O_FILEMAP`` may cause a fatal
+        crash if the memory mapped read operation fails.
+
+.. c:function:: int uv_fs_unlink(uv_loop_t* loop, uv_fs_t* req, const char* path, uv_fs_cb cb)
+

+
+    Equivalent to :man:`pwritev(2)`. If the `offset` argument is `-1`, then

+
+    .. warning::
+        On Windows, under non-MSVC environments (e.g. when GCC or Clang is used

+
+.. c:function:: int uv_fs_mkdir(uv_loop_t* loop, uv_fs_t* req, const char* path, int mode, uv_fs_cb cb)
+
+    Equivalent to :man:`mkdir(2)`.
+

+
+.. c:function:: int uv_fs_mkdtemp(uv_loop_t* loop, uv_fs_t* req, const char* tpl, uv_fs_cb cb)
+
+    Equivalent to :man:`mkdtemp(3)`. The result can be found as a null terminated string at `req->path`.

+.. c:function:: int uv_fs_mkstemp(uv_loop_t* loop, uv_fs_t* req, const char* tpl, uv_fs_cb cb)
+
+    Equivalent to :man:`mkstemp(3)`. The created file path can be found as a null terminated string at `req->path`.

+
+.. c:function:: int uv_fs_rmdir(uv_loop_t* loop, uv_fs_t* req, const char* path, uv_fs_cb cb)
+
+    Equivalent to :man:`rmdir(2)`.
+
+.. c:function:: int uv_fs_opendir(uv_loop_t* loop, uv_fs_t* req, const char* path, uv_fs_cb cb)
+
+    Opens `path` as a directory stream. On success, a `uv_dir_t` is allocated
+    and returned via `req->ptr`. This memory is not freed by
+    `uv_fs_req_cleanup()`, although `req->ptr` is set to `NULL`. The allocated
+    memory must be freed by calling `uv_fs_closedir()`. On failure, no memory
+    is allocated.
+
+    The contents of the directory can be iterated over by passing the resulting
+    `uv_dir_t` to `uv_fs_readdir()`.
+
+    .. versionadded:: 1.28.0
+
+.. c:function:: int uv_fs_closedir(uv_loop_t* loop, uv_fs_t* req, uv_dir_t* dir, uv_fs_cb cb)
+
+    Closes the directory stream represented by `dir` and frees the memory
+    allocated by `uv_fs_opendir()`.
+
+    .. versionadded:: 1.28.0
+
+.. c:function:: int uv_fs_readdir(uv_loop_t* loop, uv_fs_t* req, uv_dir_t* dir, uv_fs_cb cb)
+
+    Iterates over the directory stream, `dir`, returned by a successful
+    `uv_fs_opendir()` call. Prior to invoking `uv_fs_readdir()`, the caller
+    must set `dir->dirents` and `dir->nentries`, representing the array of
+    :c:type:`uv_dirent_t` elements used to hold the read directory entries and
+    its size.
+
+    On success, the result is an integer >= 0 representing the number of entries
+    read from the stream.
+
+    .. versionadded:: 1.28.0
+
+    .. warning::
+        `uv_fs_readdir()` is not thread safe.
+
+    .. note::
+        This function does not return the "." and ".." entries.
+
+    .. note::
+        On success this function allocates memory that must be freed using
+        `uv_fs_req_cleanup()`. `uv_fs_req_cleanup()` must be called before
+        closing the directory with `uv_fs_closedir()`.
+
+.. c:function:: int uv_fs_scandir(uv_loop_t* loop, uv_fs_t* req, const char* path, int flags, uv_fs_cb cb)
+.. c:function:: int uv_fs_scandir_next(uv_fs_t* req, uv_dirent_t* ent)
+
+    Equivalent to :man:`scandir(3)`, with a slightly different API. Once the callback
+    for the request is called, the user can use :c:func:`uv_fs_scandir_next` to
+    get `ent` populated with the next directory entry data. When there are no
+    more entries ``UV_EOF`` will be returned.

+
+    - `UV_FS_COPYFILE_EXCL`: If present, `uv_fs_copyfile()` will fail with

+
+    .. warning::
+        This function has certain platform-specific caveats that were discovered when used in Node.
+
+        * macOS and other BSDs: this function will fail with UV_ELOOP if more than 32 symlinks are
+          found while resolving the given path.  This limit is hardcoded and cannot be sidestepped.
+        * Windows: while this function works in the common case, there are a number of corner cases
+          where it doesn't:
+
+          - Paths in ramdisk volumes created by tools which sidestep the Volume Manager (such as ImDisk)
+            cannot be resolved.
+          - Inconsistent casing when using drive letters.
+          - Resolved path bypasses subst'd drives.
+
+        While this function can still be used, it's not recommended if scenarios such as the
+        above need to be supported.

+
+File open constants
+-------------------
+
+.. c:macro:: UV_FS_O_APPEND
+
+    The file is opened in append mode. Before each write, the file offset is
+    positioned at the end of the file.
+
+.. c:macro:: UV_FS_O_CREAT
+
+    The file is created if it does not already exist.
+
+.. c:macro:: UV_FS_O_DIRECT
+
+    File I/O is done directly to and from user-space buffers, which must be
+    aligned. Buffer size and address should be a multiple of the physical sector
+    size of the block device.
+
+    .. note::
+        `UV_FS_O_DIRECT` is supported on Linux, and on Windows via
+        `FILE_FLAG_NO_BUFFERING <https://docs.microsoft.com/en-us/windows/win32/fileio/file-buffering>`_.
+        `UV_FS_O_DIRECT` is not supported on macOS.
+
+.. c:macro:: UV_FS_O_DIRECTORY
+
+    If the path is not a directory, fail the open.
+
+    .. note::
+        `UV_FS_O_DIRECTORY` is not supported on Windows.
+
+.. c:macro:: UV_FS_O_DSYNC
+
+    The file is opened for synchronous I/O. Write operations will complete once
+    all data and a minimum of metadata are flushed to disk.
+
+    .. note::
+        `UV_FS_O_DSYNC` is supported on Windows via
+        `FILE_FLAG_WRITE_THROUGH <https://docs.microsoft.com/en-us/windows/win32/fileio/file-buffering>`_.
+
+.. c:macro:: UV_FS_O_EXCL
+
+    If the `O_CREAT` flag is set and the file already exists, fail the open.
+
+    .. note::
+        In general, the behavior of `O_EXCL` is undefined if it is used without
+        `O_CREAT`. There is one exception: on Linux 2.6 and later, `O_EXCL` can
+        be used without `O_CREAT` if pathname refers to a block device. If the
+        block device is in use by the system (e.g., mounted), the open will fail
+        with the error `EBUSY`.

+
+.. c:macro:: UV_FS_O_NOCTTY
+
+    If the path identifies a terminal device, opening the path will not cause
+    that terminal to become the controlling terminal for the process (if the
+    process does not already have one).
+
+    .. note::
+        `UV_FS_O_NOCTTY` is not supported on Windows.
+
+.. c:macro:: UV_FS_O_NOFOLLOW
+
+    If the path is a symbolic link, fail the open.

+:c:type:`uv_fs_event_t` --- FS Event handle
+===========================================
+
+FS Event handles allow the user to monitor a given path for changes, for example,
+if the file was renamed or there was a generic change in it. This handle uses
+the best backend for the job on each platform.
+
+.. note::
+    For AIX, the non default IBM bos.ahafs package has to be installed.
+    The AIX Event Infrastructure file system (ahafs) has some limitations:
+
+        - ahafs tracks monitoring per process and is not thread safe. A separate process
+          must be spawned for each monitor for the same event.
+        - Events for file modification (writing to a file) are not received if only the
+          containing folder is watched.
+
+    See documentation_ for more details.
+
+    The z/OS file system events monitoring infrastructure does not notify of file
+    creation/deletion within a directory that is being monitored.
+    See the `IBM Knowledge centre`_ for more details.

+:c:type:`uv_fs_poll_t` --- FS Poll handle
+=========================================
+
+FS Poll handles allow the user to monitor a given path for changes. Unlike
+:c:type:`uv_fs_event_t`, fs poll handles use `stat` to detect when a file has
+changed so they can work on file systems where fs event handles can't.
+
+
+Data types
+----------
+
+.. c:type:: uv_fs_poll_t
+
+    FS Poll handle type.
+
+.. c:type:: void (*uv_fs_poll_cb)(uv_fs_poll_t* handle, int status, const uv_stat_t* prev, const uv_stat_t* curr)
+
+    Callback passed to :c:func:`uv_fs_poll_start` which will be called repeatedly
+    after the handle is started, when any change happens to the monitored path.
+
+    The callback is invoked with `status < 0` if `path` does not exist
+    or is inaccessible. The watcher is *not* stopped but your callback is
+    not called again until something changes (e.g. when the file is created
+    or the error reason changes).
+
+    When `status == 0`, the callback receives pointers to the old and new
+    :c:type:`uv_stat_t` structs. They are valid for the duration of the
+    callback only.

+About
+=====
+
+`Nikhil Marathe <https://nikhilism.com>`_ started writing this book one
+afternoon (June 16, 2012) when he didn't feel like programming. He had recently
+been stung by the lack of good documentation on libuv while working on
+`node-taglib <https://github.com/nikhilm/node-taglib>`_. Although reference
+documentation was present, there were no comprehensive tutorials. This book is
+the output of that need and tries to be accurate. That said, the book may have
+mistakes. Pull requests are encouraged.
+
+Nikhil is indebted to Marc Lehmann's comprehensive `man page
+<http://pod.tst.eu/http://cvs.schmorp.de/libev/ev.pod>`_ about libev which
+describes much of the semantics of the two libraries.
+
+This book was made using `Sphinx <https://www.sphinx-doc.org>`_ and `vim
+<https://www.vim.org>`_.
+
+.. note::
+    In 2017 the libuv project incorporated the Nikhil's work into the official
+    documentation and it's maintained there henceforth.

+Basics of libuv
+===============
+
+libuv enforces an **asynchronous**, **event-driven** style of programming.  Its
+core job is to provide an event loop and callback based notifications of I/O
+and other activities.  libuv offers core utilities like timers, non-blocking
+networking support, asynchronous file system access, child processes and more.
+
+Event loops
+-----------
+
+In event-driven programming, an application expresses interest in certain events
+and respond to them when they occur. The responsibility of gathering events
+from the operating system or monitoring other sources of events is handled by
+libuv, and the user can register callbacks to be invoked when an event occurs.
+The event-loop usually keeps running *forever*. In pseudocode:
+
+.. code-block:: python
+
+    while there are still events to process:
+        e = get the next event
+        if there is a callback associated with e:
+            call the callback
+
+Some examples of events are:
+
+* File is ready for writing
+* A socket has data ready to be read
+* A timer has timed out
+
+This event loop is encapsulated by ``uv_run()`` -- the end-all function when using
+libuv.
+
+The most common activity of systems programs is to deal with input and output,
+rather than a lot of number-crunching. The problem with using conventional
+input/output functions (``read``, ``fprintf``, etc.) is that they are
+**blocking**. The actual write to a hard disk or reading from a network, takes
+a disproportionately long time compared to the speed of the processor. The
+functions don't return until the task is done, so that your program is doing
+nothing. For programs which require high performance this is a major roadblock
+as other activities and other I/O operations are kept waiting.
+
+One of the standard solutions is to use threads. Each blocking I/O operation is
+started in a separate thread (or in a thread pool). When the blocking function
+gets invoked in the thread, the operating system can schedule another thread to run,
+which actually needs the CPU.
+
+The approach followed by libuv uses another style, which is the **asynchronous,
+non-blocking** style. Most modern operating systems provide event notification
+subsystems. For example, a normal ``read`` call on a socket would block until
+the sender actually sent something. Instead, the application can request the
+operating system to watch the socket and put an event notification in the
+queue. The application can inspect the events at its convenience (perhaps doing
+some number crunching before to use the processor to the maximum) and grab the
+data. It is **asynchronous** because the application expressed interest at one
+point, then used the data at another point (in time and space). It is
+**non-blocking** because the application process was free to do other tasks.
+This fits in well with libuv's event-loop approach, since the operating system
+events can be treated as just another libuv event. The non-blocking ensures
+that other events can continue to be handled as fast as they come in [#]_.
+
+.. NOTE::
+
+    How the I/O is run in the background is not of our concern, but due to the
+    way our computer hardware works, with the thread as the basic unit of the
+    processor, libuv and OSes will usually run background/worker threads and/or
+    polling to perform tasks in a non-blocking manner.
+
+Bert Belder, one of the libuv core developers has a small video explaining the
+architecture of libuv and its background. If you have no prior experience with
+either libuv or libev, it is a quick, useful watch.
+
+libuv's event loop is explained in more detail in the `documentation
+<https://docs.libuv.org/en/v1.x/design.html#the-i-o-loop>`_.

+
+Hello World
+-----------
+
+With the basics out of the way, let's write our first libuv program. It does
+nothing, except start a loop which will exit immediately.
+
+.. rubric:: helloworld/main.c
+.. literalinclude:: ../../code/helloworld/main.c
+    :language: c
+    :linenos:
+
+This program quits immediately because it has no events to process. A libuv
+event loop has to be told to watch out for events using the various API
+functions.
+
+Starting with libuv v1.0, users should allocate the memory for the loops before
+initializing it with ``uv_loop_init(uv_loop_t *)``. This allows you to plug in
+custom memory management. Remember to de-initialize the loop using
+``uv_loop_close(uv_loop_t *)`` and then delete the storage. The examples never
+close loops since the program quits after the loop ends and the system will
+reclaim memory. Production grade projects, especially long running systems
+programs, should take care to release correctly.
+
+Default loop
+++++++++++++
+
+A default loop is provided by libuv and can be accessed using
+``uv_default_loop()``. You should use this loop if you only want a single
+loop.
+
+.. rubric:: default-loop/main.c
+.. literalinclude:: ../../code/default-loop/main.c
+    :language: c
+    :linenos:
+
+.. note::
+
+    node.js uses the default loop as its main loop. If you are writing bindings
+    you should be aware of this.
+
+.. _libuv-error-handling:
+
+Error handling
+--------------
+
+Initialization functions or synchronous functions which may fail return a negative number on error. Async functions that may fail will pass a status parameter to their callbacks. The error messages are defined as ``UV_E*`` `constants`_.
+
+.. _constants: https://docs.libuv.org/en/v1.x/errors.html#error-constants
+
+You can use the ``uv_strerror(int)`` and ``uv_err_name(int)`` functions
+to get a ``const char *`` describing the error or the error name respectively.
+
+I/O read callbacks (such as for files and sockets) are passed a parameter ``nread``. If ``nread`` is less than 0, there was an error (UV_EOF is the end of file error, which you may want to handle differently).
+
+Handles and Requests
+--------------------
+
+libuv works by the user expressing interest in particular events. This is
+usually done by creating a **handle** to an I/O device, timer or process.
+Handles are opaque structs named as ``uv_TYPE_t`` where type signifies what the
+handle is used for.
+
+.. rubric:: libuv watchers
+.. code-block:: c
+
+    /* Handle types. */
+    typedef struct uv_loop_s uv_loop_t;
+    typedef struct uv_handle_s uv_handle_t;
+    typedef struct uv_dir_s uv_dir_t;
+    typedef struct uv_stream_s uv_stream_t;
+    typedef struct uv_tcp_s uv_tcp_t;

+
+    /* Request types. */
+    typedef struct uv_req_s uv_req_t;
+    typedef struct uv_getaddrinfo_s uv_getaddrinfo_t;
+    typedef struct uv_getnameinfo_s uv_getnameinfo_t;
+    typedef struct uv_shutdown_s uv_shutdown_t;
+    typedef struct uv_write_s uv_write_t;
+    typedef struct uv_connect_s uv_connect_t;
+    typedef struct uv_udp_send_s uv_udp_send_t;
+    typedef struct uv_fs_s uv_fs_t;
+    typedef struct uv_work_s uv_work_t;
+    typedef struct uv_random_s uv_random_t;
+
+    /* None of the above. */
+    typedef struct uv_env_item_s uv_env_item_t;
+    typedef struct uv_cpu_info_s uv_cpu_info_t;
+    typedef struct uv_interface_address_s uv_interface_address_t;
+    typedef struct uv_dirent_s uv_dirent_t;
+    typedef struct uv_passwd_s uv_passwd_t;
+    typedef struct uv_utsname_s uv_utsname_t;
+    typedef struct uv_statfs_s uv_statfs_t;
+
+
+Handles represent long-lived objects. Async operations on such handles are
+identified using **requests**. A request is short-lived (usually used across
+only one callback) and usually indicates one I/O operation on a handle.
+Requests are used to preserve context between the initiation and the callback
+of individual actions. For example, an UDP socket is represented by
+a ``uv_udp_t``, while individual writes to the socket use a ``uv_udp_send_t``
+structure that is passed to the callback after the write is done.
+
+Handles are setup by a corresponding::
+
+    uv_TYPE_init(uv_loop_t *, uv_TYPE_t *)
+
+function.
+
+Callbacks are functions which are called by libuv whenever an event the watcher
+is interested in has taken place. Application specific logic will usually be
+implemented in the callback. For example, an IO watcher's callback will receive
+the data read from a file, a timer callback will be triggered on timeout and so
+on.
+
+Idling
+++++++
+
+Here is an example of using an idle handle. The callback is called once on
+every turn of the event loop. A use case for idle handles is discussed in
+:doc:`utilities`. Let us use an idle watcher to look at the watcher life cycle
+and see how ``uv_run()`` will now block because a watcher is present. The idle
+watcher is stopped when the count is reached and ``uv_run()`` exits since no
+event watchers are active.
+
+.. rubric:: idle-basic/main.c
+.. literalinclude:: ../../code/idle-basic/main.c
+    :language: c
+    :emphasize-lines: 6,10,14-17
+
+Storing context
++++++++++++++++
+
+In callback based programming style you'll often want to pass some 'context' --
+application specific information -- between the call site and the callback. All
+handles and requests have a ``void* data`` member which you can set to the
+context and cast back in the callback. This is a common pattern used throughout
+the C library ecosystem. In addition ``uv_loop_t`` also has a similar data
+member.

+Advanced event loops
+====================
+
+libuv provides considerable user control over event loops, and you can achieve
+interesting results by juggling multiple loops. You can also embed libuv's
+event loop into another event loop based library -- imagine a Qt based UI, and
+Qt's event loop driving a libuv backend which does intensive system level
+tasks.
+
+Stopping an event loop
+~~~~~~~~~~~~~~~~~~~~~~
+
+``uv_stop()`` can be used to stop an event loop. The earliest the loop will
+stop running is *on the next iteration*, possibly later. This means that events
+that are ready to be processed in this iteration of the loop will still be
+processed, so ``uv_stop()`` can't be used as a kill switch. When ``uv_stop()``
+is called, the loop **won't** block for i/o on this iteration. The semantics of
+these things can be a bit difficult to understand, so let's look at
+``uv_run()`` where all the control flow occurs.
+
+.. rubric:: src/unix/core.c - uv_run
+.. literalinclude:: ../../../src/unix/core.c
+    :language: c
+    :linenos:
+    :lines: 304-324
+    :emphasize-lines: 10,19,21
+
+``stop_flag`` is set by ``uv_stop()``. Now all libuv callbacks are invoked
+within the event loop, which is why invoking ``uv_stop()`` in them will still
+lead to this iteration of the loop occurring. First libuv updates timers, then
+runs pending timer, idle and prepare callbacks, and invokes any pending I/O
+callbacks. If you were to call ``uv_stop()`` in any of them, ``stop_flag``
+would be set. This causes ``uv_backend_timeout()`` to return ``0``, which is
+why the loop does not block on I/O. If on the other hand, you called
+``uv_stop()`` in one of the check handlers, I/O has already finished and is not
+affected.
+
+``uv_stop()`` is useful to shutdown a loop when a result has been computed or
+there is an error, without having to ensure that all handlers are stopped one
+by one.
+
+Here is a simple example that stops the loop and demonstrates how the current
+iteration of the loop still takes places.

+Filesystem
+==========
+
+Simple filesystem read/write is achieved using the ``uv_fs_*`` functions and the
+``uv_fs_t`` struct.
+
+.. note::
+
+    The libuv filesystem operations are different from :doc:`socket operations
+    <networking>`. Socket operations use the non-blocking operations provided
+    by the operating system. Filesystem operations use blocking functions
+    internally, but invoke these functions in a `thread pool`_ and notify
+    watchers registered with the event loop when application interaction is
+    required.
+
+.. _thread pool: https://docs.libuv.org/en/v1.x/threadpool.html#thread-pool-work-scheduling
+
+All filesystem functions have two forms - *synchronous* and *asynchronous*.
+
+The *synchronous* forms automatically get called (and **block**) if the
+callback is null. The return value of functions is a :ref:`libuv error code
+<libuv-error-handling>`. This is usually only useful for synchronous calls.
+The *asynchronous* form is called when a callback is passed and the return
+value is 0.
+
+Reading/Writing files
+---------------------
+
+A file descriptor is obtained using
+
+.. code-block:: c
+
+    int uv_fs_open(uv_loop_t* loop, uv_fs_t* req, const char* path, int flags, int mode, uv_fs_cb cb)
+
+``flags`` and ``mode`` are standard
+`Unix flags <https://man7.org/linux/man-pages/man2/open.2.html>`_.
+libuv takes care of converting to the appropriate Windows flags.
+
+File descriptors are closed using
+
+.. code-block:: c
+
+    int uv_fs_close(uv_loop_t* loop, uv_fs_t* req, uv_file file, uv_fs_cb cb)
+
+
+Filesystem operation callbacks have the signature:
+
+.. code-block:: c
+
+    void callback(uv_fs_t* req);
+
+Let's see a simple implementation of ``cat``. We start with registering
+a callback for when the file is opened:
+
+.. rubric:: uvcat/main.c - opening a file
+.. literalinclude:: ../../code/uvcat/main.c
+    :language: c
+    :linenos:
+    :lines: 41-53
+    :emphasize-lines: 4, 6-7
+
+The ``result`` field of a ``uv_fs_t`` is the file descriptor in case of the
+``uv_fs_open`` callback. If the file is successfully opened, we start reading it.
+
+.. rubric:: uvcat/main.c - read callback
+.. literalinclude:: ../../code/uvcat/main.c
+    :language: c
+    :linenos:
+    :lines: 26-39
+    :emphasize-lines: 2,8,12
+
+In the case of a read call, you should pass an *initialized* buffer which will
+be filled with data before the read callback is triggered. The ``uv_fs_*``
+operations map almost directly to certain POSIX functions, so EOF is indicated
+in this case by ``result`` being 0. In the case of streams or pipes, the
+``UV_EOF`` constant would have been passed as a status instead.
+
+Here you see a common pattern when writing asynchronous programs. The
+``uv_fs_close()`` call is performed synchronously. *Usually tasks which are
+one-off, or are done as part of the startup or shutdown stage are performed
+synchronously, since we are interested in fast I/O when the program is going
+about its primary task and dealing with multiple I/O sources*. For solo tasks
+the performance difference usually is negligible and may lead to simpler code.
+
+Filesystem writing is similarly simple using ``uv_fs_write()``.  *Your callback
+will be triggered after the write is complete*.  In our case the callback
+simply drives the next read. Thus read and write proceed in lockstep via
+callbacks.

+    :linenos:

+    :emphasize-lines: 6
+
+.. warning::
+
+    Due to the way filesystems and disk drives are configured for performance,
+    a write that 'succeeds' may not be committed to disk yet.
+
+We set the dominos rolling in ``main()``:

+.. rubric:: uvcat/main.c

+
+.. warning::
+
+    The ``uv_fs_req_cleanup()`` function must always be called on filesystem
+    requests to free internal memory allocations in libuv.
+
+Filesystem operations
+---------------------
+
+All the standard filesystem operations like ``unlink``, ``rmdir``, ``stat`` are
+supported asynchronously and have intuitive argument order. They follow the

+
+Buffers and Streams
+-------------------
+
+The basic I/O handle in libuv is the stream (``uv_stream_t``). TCP sockets, UDP
+sockets, and pipes for file I/O and IPC are all treated as stream subclasses.
+
+Streams are initialized using custom functions for each subclass, then operated
+upon using
+
+.. code-block:: c
+
+    int uv_read_start(uv_stream_t*, uv_alloc_cb alloc_cb, uv_read_cb read_cb);
+    int uv_read_stop(uv_stream_t*);
+    int uv_write(uv_write_t* req, uv_stream_t* handle,
+                 const uv_buf_t bufs[], unsigned int nbufs, uv_write_cb cb);
+
+The stream based functions are simpler to use than the filesystem ones and
+libuv will automatically keep reading from a stream when ``uv_read_start()`` is
+called once, until ``uv_read_stop()`` is called.
+
+The discrete unit of data is the buffer -- ``uv_buf_t``. This is simply
+a collection of a pointer to bytes (``uv_buf_t.base``) and the length
+(``uv_buf_t.len``). The ``uv_buf_t`` is lightweight and passed around by value.
+What does require management is the actual bytes, which have to be allocated
+and freed by the application.
+
+.. ERROR::
+
+    **THIS PROGRAM DOES NOT ALWAYS WORK, NEED SOMETHING BETTER**
+
+To demonstrate streams we will need to use ``uv_pipe_t``. This allows streaming
+local files [#]_. Here is a simple tee utility using libuv.  Doing all operations
+asynchronously shows the power of evented I/O. The two writes won't block each
+other, but we have to be careful to copy over the buffer data to ensure we don't
+free a buffer until it has been written.
+
+The program is to be executed as::
+
+    ./uvtee <output_file>
+
+We start off opening pipes on the files we require. libuv pipes to a file are
+opened as bidirectional by default.
+
+.. rubric:: uvtee/main.c - read on pipes
+.. literalinclude:: ../../code/uvtee/main.c
+    :language: c
+    :linenos:
+    :lines: 62-80
+    :emphasize-lines: 4,5,15
+
+The third argument of ``uv_pipe_init()`` should be set to 1 for IPC using named
+pipes. This is covered in :doc:`processes`. The ``uv_pipe_open()`` call
+associates the pipe with the file descriptor, in this case ``0`` (standard
+input).
+
+We start monitoring ``stdin``. The ``alloc_buffer`` callback is invoked as new
+buffers are required to hold incoming data. ``read_stdin`` will be called with
+these buffers.
+
+.. rubric:: uvtee/main.c - reading buffers
+.. literalinclude:: ../../code/uvtee/main.c
+    :language: c
+    :linenos:
+    :lines: 19-22,44-60
+
+The standard ``malloc`` is sufficient here, but you can use any memory allocation
+scheme. For example, node.js uses its own slab allocator which associates
+buffers with V8 objects.
+
+The read callback ``nread`` parameter is less than 0 on any error. This error
+might be EOF, in which case we close all the streams, using the generic close
+function ``uv_close()`` which deals with the handle based on its internal type.
+Otherwise ``nread`` is a non-negative number and we can attempt to write that
+many bytes to the output streams. Finally remember that buffer allocation and
+deallocation is application responsibility, so we free the data.
+
+The allocation callback may return a buffer with length zero if it fails to
+allocate memory. In this case, the read callback is invoked with error
+UV_ENOBUFS. libuv will continue to attempt to read the stream though, so you
+must explicitly call ``uv_close()`` if you want to stop when allocation fails.
+
+The read callback may be called with ``nread = 0``, indicating that at this
+point there is nothing to be read. Most applications will just ignore this.
+
+.. rubric:: uvtee/main.c - Write to pipe
+.. literalinclude:: ../../code/uvtee/main.c
+    :language: c
+    :linenos:
+    :lines: 9-13,23-42
+
+``write_data()`` makes a copy of the buffer obtained from read. This buffer
+does not get passed through to the write callback trigged on write completion. To
+get around this we wrap a write request and a buffer in ``write_req_t`` and
+unwrap it in the callbacks. We make a copy so we can free the two buffers from
+the two calls to ``write_data`` independently of each other. While acceptable
+for a demo program like this, you'll probably want smarter memory management,
+like reference counted buffers or a pool of buffers in any major application.
+
+.. WARNING::
+
+    If your program is meant to be used with other programs it may knowingly or
+    unknowingly be writing to a pipe. This makes it susceptible to `aborting on
+    receiving a SIGPIPE`_. It is a good idea to insert::
+
+        signal(SIGPIPE, SIG_IGN)
+
+    in the initialization stages of your application.

+.. _aborting on receiving a SIGPIPE: http://pod.tst.eu/http://cvs.schmorp.de/libev/ev.pod#The_special_problem_of_SIGPIPE
+
+File change events
+------------------
+
+All modern operating systems provide APIs to put watches on individual files or
+directories and be informed when the files are modified. libuv wraps common
+file change notification libraries [#fsnotify]_. This is one of the more
+inconsistent parts of libuv. File change notification systems are themselves
+extremely varied across platforms so getting everything working everywhere is
+difficult. To demonstrate, I'm going to build a simple utility which runs
+a command whenever any of the watched files change::
+
+    ./onchange <command> <file1> [file2] ...
+
+.. note::
+
+    Currently this example only works on OSX and Windows.
+    Refer to the `notes of uv_fs_event_start`_ function.
+
+.. _notes of uv_fs_event_start: https://docs.libuv.org/en/v1.x/fs_event.html#c.uv_fs_event_start
+
+The file change notification is started using ``uv_fs_event_init()``:
+
+.. rubric:: onchange/main.c - The setup
+.. literalinclude:: ../../code/onchange/main.c
+    :language: c
+    :linenos:
+    :lines: 26-
+    :emphasize-lines: 15
+
+The third argument is the actual file or directory to monitor. The last
+argument, ``flags``, can be:
+
+.. code-block:: c
+
+    /*
+     * Flags to be passed to uv_fs_event_start().
+     */
+    enum uv_fs_event_flags {
+        UV_FS_EVENT_WATCH_ENTRY = 1,
+        UV_FS_EVENT_STAT = 2,
+        UV_FS_EVENT_RECURSIVE = 4
+    };
+
+``UV_FS_EVENT_WATCH_ENTRY`` and ``UV_FS_EVENT_STAT`` don't do anything (yet).
+``UV_FS_EVENT_RECURSIVE`` will start watching subdirectories as well on
+supported platforms.
+
+The callback will receive the following arguments:
+
+  #. ``uv_fs_event_t *handle`` - The handle. The ``path`` field of the handle
+     is the file on which the watch was set.
+  #. ``const char *filename`` - If a directory is being monitored, this is the
+     file which was changed. Only non-``null`` on Linux and Windows. May be ``null``
+     even on those platforms.
+  #. ``int events`` - one of ``UV_RENAME`` or ``UV_CHANGE``, or a bitwise OR of
+     both.
+  #. ``int status`` - If ``status < 0``, there is an :ref:`libuv error<libuv-error-handling>`.
+
+In our example we simply print the arguments and run the command using
+``system()``.

+Introduction
+============
+
+This 'book' is a small set of tutorials about using libuv_ as
+a high performance evented I/O library which offers the same API on Windows and Unix.
+
+It is meant to cover the main areas of libuv, but is not a comprehensive
+reference discussing every function and data structure. The `official libuv
+documentation`_ may be consulted for full details.
+
+.. _official libuv documentation: https://docs.libuv.org/en/v1.x/
+
+This book is still a work in progress, so sections may be incomplete, but
+I hope you will enjoy it as it grows.
+
+Who this book is for
+--------------------
+
+If you are reading this book, you are either:
+
+1) a systems programmer, creating low-level programs such as daemons or network
+   services and clients. You have found that the event loop approach is well
+   suited for your application and decided to use libuv.
+
+2) a node.js module writer, who wants to wrap platform APIs
+   written in C or C++ with a set of (a)synchronous APIs that are exposed to
+   JavaScript. You will use libuv purely in the context of node.js. For
+   this you will require some other resources as the book does not cover parts
+   specific to v8/node.js.
+
+This book assumes that you are comfortable with the C programming language.
+
+Background
+----------
+
+The node.js_ project began in 2009 as a JavaScript environment decoupled
+from the browser. Using Google's V8_ and Marc Lehmann's libev_, node.js
+combined a model of I/O -- evented -- with a language that was well suited to
+the style of programming; due to the way it had been shaped by browsers. As
+node.js grew in popularity, it was important to make it work on Windows, but
+libev ran only on Unix. The Windows equivalent of kernel event notification
+mechanisms like kqueue or (e)poll is IOCP. libuv was an abstraction around libev
+or IOCP depending on the platform, providing users an API based on libev.
+In the node-v0.9.0 version of libuv `libev was removed`_.
+
+Since then libuv has continued to mature and become a high quality standalone
+library for system programming. Users outside of node.js include Mozilla's
+Rust_ programming language, and a variety_ of language bindings.
+
+This book and the code is based on libuv version `v1.42.0`_.
+
+Code
+----
+
+All the example code and the source of the book is included as part of
+the libuv_ project on GitHub.
+Clone or Download libuv_, then build it::
+
+    sh autogen.sh
+    ./configure
+    make
+
+There is no need to ``make install``. To build the examples run ``make`` in the
+``docs/code/`` directory.

+Networking
+==========
+
+Networking in libuv is not much different from directly using the BSD socket
+interface, some things are easier, all are non-blocking, but the concepts stay
+the same. In addition libuv offers utility functions to abstract the annoying,
+repetitive and low-level tasks like setting up sockets using the BSD socket
+structures, DNS lookup, and tweaking various socket parameters.
+
+The ``uv_tcp_t`` and ``uv_udp_t`` structures are used for network I/O.
+
+.. NOTE::
+
+  The code samples in this chapter exist to show certain libuv APIs. They are
+  not examples of good quality code. They leak memory and don't always close
+  connections properly.
+
+TCP
+---
+
+TCP is a connection oriented, stream protocol and is therefore based on the
+libuv streams infrastructure.
+
+Server
+++++++
+
+Server sockets proceed by:
+
+1. ``uv_tcp_init`` the TCP handle.
+2. ``uv_tcp_bind`` it.
+3. Call ``uv_listen`` on the handle to have a callback invoked whenever a new
+   connection is established by a client.
+4. Use ``uv_accept`` to accept the connection.
+5. Use :ref:`stream operations <buffers-and-streams>` to communicate with the
+   client.
+
+Here is a simple echo server
+
+.. rubric:: tcp-echo-server/main.c - The listen socket
+.. literalinclude:: ../../code/tcp-echo-server/main.c
+    :language: c
+    :linenos:
+    :lines: 68-
+    :emphasize-lines: 4-5,7-10
+
+You can see the utility function ``uv_ip4_addr`` being used to convert from
+a human readable IP address, port pair to the sockaddr_in structure required by
+the BSD socket APIs. The reverse can be obtained using ``uv_ip4_name``.
+
+.. NOTE::
+
+    There are ``uv_ip6_*`` analogues for the ip4 functions.
+
+Most of the setup functions are synchronous since they are CPU-bound.
+``uv_listen`` is where we return to libuv's callback style. The second
+arguments is the backlog queue -- the maximum length of queued connections.
+
+When a connection is initiated by clients, the callback is required to set up
+a handle for the client socket and associate the handle using ``uv_accept``.
+In this case we also establish interest in reading from this stream.
+
+.. rubric:: tcp-echo-server/main.c - Accepting the client
+.. literalinclude:: ../../code/tcp-echo-server/main.c
+    :language: c
+    :linenos:
+    :lines: 51-66
+    :emphasize-lines: 9-10
+
+The remaining set of functions is very similar to the streams example and can
+be found in the code. Just remember to call ``uv_close`` when the socket isn't
+required. This can be done even in the ``uv_listen`` callback if you are not
+interested in accepting the connection.
+
+Client
+++++++
+
+Where you do bind/listen/accept on the server, on the client side it's simply
+a matter of calling ``uv_tcp_connect``. The same ``uv_connect_cb`` style
+callback of ``uv_listen`` is used by ``uv_tcp_connect``. Try::
+
+    uv_tcp_t* socket = (uv_tcp_t*)malloc(sizeof(uv_tcp_t));
+    uv_tcp_init(loop, socket);
+
+    uv_connect_t* connect = (uv_connect_t*)malloc(sizeof(uv_connect_t));
+
+    struct sockaddr_in dest;
+    uv_ip4_addr("127.0.0.1", 80, &dest);
+
+    uv_tcp_connect(connect, socket, (const struct sockaddr*)&dest, on_connect);
+
+where ``on_connect`` will be called after the connection is established. The
+callback receives the ``uv_connect_t`` struct, which has a member ``.handle``
+pointing to the socket.
+
+UDP
+---
+
+The `User Datagram Protocol`_ offers connectionless, unreliable network
+communication. Hence libuv doesn't offer a stream. Instead libuv provides
+non-blocking UDP support via the `uv_udp_t` handle (for receiving) and
+`uv_udp_send_t` request (for sending) and related functions. That said, the
+actual API for reading/writing is very similar to normal stream reads. To look
+at how UDP can be used, the example shows the first stage of obtaining an IP
+address from a `DHCP`_ server -- DHCP Discover.
+
+.. note::
+
+    You will have to run `udp-dhcp` as **root** since it uses well known port
+    numbers below 1024.
+
+.. rubric:: udp-dhcp/main.c - Setup and send UDP packets
+.. literalinclude:: ../../code/udp-dhcp/main.c
+    :language: c
+    :linenos:
+    :lines: 7-11,104-
+    :emphasize-lines: 8,10-11,17-18,21
+
+.. note::
+
+    The IP address ``0.0.0.0`` is used to bind to all interfaces. The IP
+    address ``255.255.255.255`` is a broadcast address meaning that packets
+    will be sent to all interfaces on the subnet.  port ``0`` means that the OS
+    randomly assigns a port.
+
+First we setup the receiving socket to bind on all interfaces on port 68 (DHCP
+client) and start a read on it. This will read back responses from any DHCP
+server that replies. We use the UV_UDP_REUSEADDR flag to play nice with any
+other system DHCP clients that are running on this computer on the same port.
+Then we setup a similar send socket and use ``uv_udp_send`` to send
+a *broadcast message* on port 67 (DHCP server).
+
+It is **necessary** to set the broadcast flag, otherwise you will get an
+``EACCES`` error [#]_. The exact message being sent is not relevant to this
+book and you can study the code if you are interested. As usual the read and
+write callbacks will receive a status code of < 0 if something went wrong.
+
+Since UDP sockets are not connected to a particular peer, the read callback
+receives an extra parameter about the sender of the packet.
+
+``nread`` may be zero if there is no more data to be read. If ``addr`` is NULL,
+it indicates there is nothing to read (the callback shouldn't do anything), if
+not NULL, it indicates that an empty datagram was received from the host at
+``addr``. The ``flags`` parameter may be ``UV_UDP_PARTIAL`` if the buffer
+provided by your allocator was not large enough to hold the data. *In this case
+the OS will discard the data that could not fit* (That's UDP for you!).

+
+UDP Options
++++++++++++
+
+Time-to-live
+~~~~~~~~~~~~
+
+The TTL of packets sent on the socket can be changed using ``uv_udp_set_ttl``.
+
+IPv6 stack only
+~~~~~~~~~~~~~~~
+
+IPv6 sockets can be used for both IPv4 and IPv6 communication. If you want to
+restrict the socket to IPv6 only, pass the ``UV_UDP_IPV6ONLY`` flag to
+``uv_udp_bind``.
+
+Multicast
+~~~~~~~~~
+
+A socket can (un)subscribe to a multicast group using:
+
+.. code::block:: c
+
+    int uv_udp_set_membership(uv_udp_t* handle, const char* multicast_addr, const char* interface_addr, uv_membership membership);
+
+where ``membership`` is ``UV_JOIN_GROUP`` or ``UV_LEAVE_GROUP``.
+
+The concepts of multicasting are nicely explained in `this guide`_.
+
+.. _this guide: https://www.tldp.org/HOWTO/Multicast-HOWTO-2.html
+
+Local loopback of multicast packets is enabled by default [#]_, use
+``uv_udp_set_multicast_loop`` to switch it off.
+
+The packet time-to-live for multicast packets can be changed using
+``uv_udp_set_multicast_ttl``.
+
+Querying DNS
+------------
+
+libuv provides asynchronous DNS resolution. For this it provides its own
+``getaddrinfo`` replacement [#]_. In the callback you can
+perform normal socket operations on the retrieved addresses. Let's connect to
+Libera.chat to see an example of DNS resolution.

+Processes
+=========
+
+libuv offers considerable child process management, abstracting the platform
+differences and allowing communication with the child process using streams or
+named pipes.
+
+A common idiom in Unix is for every process to do one thing and do it well. In
+such a case, a process often uses multiple child processes to achieve tasks
+(similar to using pipes in shells). A multi-process model with messages
+may also be easier to reason about compared to one with threads and shared
+memory.
+
+A common refrain against event-based programs is that they cannot take
+advantage of multiple cores in modern computers. In a multi-threaded program
+the kernel can perform scheduling and assign different threads to different
+cores, improving performance. But an event loop has only one thread.  The
+workaround can be to launch multiple processes instead, with each process
+running an event loop, and each process getting assigned to a separate CPU
+core.
+
+Spawning child processes
+------------------------
+
+The simplest case is when you simply want to launch a process and know when it
+exits. This is achieved using ``uv_spawn``.
+
+.. rubric:: spawn/main.c
+.. literalinclude:: ../../code/spawn/main.c
+    :language: c
+    :linenos:
+    :lines: 6-8,15-
+    :emphasize-lines: 11,13-17
+
+.. NOTE::
+
+    ``options`` is implicitly initialized with zeros since it is a global
+    variable.  If you change ``options`` to a local variable, remember to
+    initialize it to null out all unused fields::
+
+        uv_process_options_t options = {0};
+
+The ``uv_process_t`` struct only acts as the handle, all options are set via
+``uv_process_options_t``. To simply launch a process, you need to set only the
+``file`` and ``args`` fields. ``file`` is the program to execute. Since
+``uv_spawn`` uses :man:`execvp(3)` internally, there is no need to supply the full
+path. Finally as per underlying conventions, **the arguments array has to be
+one larger than the number of arguments, with the last element being NULL**.
+
+After the call to ``uv_spawn``, ``uv_process_t.pid`` will contain the process
+ID of the child process.
+
+The exit callback will be invoked with the *exit status* and the type of *signal*
+which caused the exit.
+
+Note that it is important **not** to call ``uv_close`` before the exit callback.
+
+.. rubric:: spawn/main.c
+.. literalinclude:: ../../code/spawn/main.c
+    :language: c
+    :linenos:
+    :lines: 9-12
+    :emphasize-lines: 3
+
+It is **required** to close the process watcher after the process exits.
+
+Changing process parameters
+---------------------------
+
+Before the child process is launched you can control the execution environment
+using fields in ``uv_process_options_t``.
+
+Change execution directory
+++++++++++++++++++++++++++
+
+Set ``uv_process_options_t.cwd`` to the corresponding directory.
+
+Set environment variables
++++++++++++++++++++++++++
+
+``uv_process_options_t.env`` is a null-terminated array of strings, each of the
+form ``VAR=VALUE`` used to set up the environment variables for the process. Set
+this to ``NULL`` to inherit the environment from the parent (this) process.
+
+Option flags
+++++++++++++
+
+Setting ``uv_process_options_t.flags`` to a bitwise OR of the following flags,
+modifies the child process behaviour:
+
+* ``UV_PROCESS_SETUID`` - sets the child's execution user ID to ``uv_process_options_t.uid``.
+* ``UV_PROCESS_SETGID`` - sets the child's execution group ID to ``uv_process_options_t.gid``.
+
+Changing the UID/GID is only supported on Unix, ``uv_spawn`` will fail on
+Windows with ``UV_ENOTSUP``.
+
+* ``UV_PROCESS_WINDOWS_VERBATIM_ARGUMENTS`` - No quoting or escaping of
+  ``uv_process_options_t.args`` is done on Windows. Ignored on Unix.
+* ``UV_PROCESS_DETACHED`` - Starts the child process in a new session, which
+  will keep running after the parent process exits. See example below.
+
+Detaching processes
+-------------------
+
+Passing the flag ``UV_PROCESS_DETACHED`` can be used to launch daemons, or
+child processes which are independent of the parent so that the parent exiting
+does not affect it.
+
+.. rubric:: detach/main.c
+.. literalinclude:: ../../code/detach/main.c
+    :language: c
+    :linenos:
+    :lines: 9-30
+    :emphasize-lines: 12,19
+
+Just remember that the handle is still monitoring the child, so your program
+won't exit. Use ``uv_unref()`` if you want to be more *fire-and-forget*.
+
+Sending signals to processes
+----------------------------
+
+libuv wraps the standard ``kill(2)`` system call on Unix and implements one
+with similar semantics on Windows, with *one caveat*: all of ``SIGTERM``,
+``SIGINT`` and ``SIGKILL``, lead to termination of the process. The signature
+of ``uv_kill`` is::
+
+    uv_err_t uv_kill(int pid, int signum);
+
+For processes started using libuv, you may use ``uv_process_kill`` instead,
+which accepts the ``uv_process_t`` watcher as the first argument, rather than
+the pid. In this case, **remember to call** ``uv_close`` on the watcher _after_
+the exit callback has been called.
+
+Signals
+-------
+
+libuv provides wrappers around Unix signals with `some Windows support
+<http://docs.libuv.org/en/v1.x/signal.html#signal>`_ as well.
+
+Use ``uv_signal_init()`` to initialize
+a handle and associate it with a loop. To listen for particular signals on
+that handler, use ``uv_signal_start()`` with the handler function. Each handler
+can only be associated with one signal number, with subsequent calls to
+``uv_signal_start()`` overwriting earlier associations. Use ``uv_signal_stop()`` to
+stop watching. Here is a small example demonstrating the various possibilities:
+
+.. rubric:: signal/main.c
+.. literalinclude:: ../../code/signal/main.c
+    :language: c
+    :linenos:
+    :emphasize-lines: 17-18,27-28
+
+.. NOTE::
+
+    ``uv_run(loop, UV_RUN_NOWAIT)`` is similar to ``uv_run(loop, UV_RUN_ONCE)``
+    in that it will process only one event. UV_RUN_ONCE blocks if there are no
+    pending events, while UV_RUN_NOWAIT will return immediately. We use NOWAIT
+    so that one of the loops isn't starved because the other one has no pending
+    activity.
+
+Send ``SIGUSR1`` to the process, and you'll find the handler being invoked
+4 times, one for each ``uv_signal_t``. The handler just stops each handle,
+so that the program exits. This sort of dispatch to all handlers is very
+useful. A server using multiple event loops could ensure that all data was
+safely saved before termination, simply by every loop adding a watcher for
+``SIGINT``.
+
+Child Process I/O
+-----------------
+
+A normal, newly spawned process has its own set of file descriptors, with 0,
+1 and 2 being ``stdin``, ``stdout`` and ``stderr`` respectively. Sometimes you
+may want to share file descriptors with the child. For example, perhaps your
+applications launches a sub-command and you want any errors to go in the log
+file, but ignore ``stdout``. For this you'd like to have ``stderr`` of the
+child be the same as the stderr of the parent. In this case, libuv supports
+*inheriting* file descriptors. In this sample, we invoke the test program,
+which is:
+
+.. rubric:: proc-streams/test.c
+.. literalinclude:: ../../code/proc-streams/test.c
+    :language: c
+
+The actual program ``proc-streams`` runs this while sharing only ``stderr``.
+The file descriptors of the child process are set using the ``stdio`` field in
+``uv_process_options_t``. First set the ``stdio_count`` field to the number of
+file descriptors being set. ``uv_process_options_t.stdio`` is an array of
+``uv_stdio_container_t``, which is:
+
+.. code-block:: c
+
+    typedef struct uv_stdio_container_s {
+        uv_stdio_flags flags;
+
+        union {
+            uv_stream_t* stream;
+            int fd;
+        } data;
+    } uv_stdio_container_t;
+
+where flags can have several values. Use ``UV_IGNORE`` if it isn't going to be
+used. If the first three ``stdio`` fields are marked as ``UV_IGNORE`` they'll
+redirect to ``/dev/null``.
+
+Since we want to pass on an existing descriptor, we'll use ``UV_INHERIT_FD``.
+Then we set the ``fd`` to ``stderr``.
+
+.. rubric:: proc-streams/main.c
+.. literalinclude:: ../../code/proc-streams/main.c
+    :language: c
+    :linenos:
+    :lines: 15-17,27-
+    :emphasize-lines: 6,10,11,12
+
+If you run ``proc-stream`` you'll see that only the line "This is stderr" will
+be displayed. Try marking ``stdout`` as being inherited and see the output.
+
+It is dead simple to apply this redirection to streams.  By setting ``flags``
+to ``UV_INHERIT_STREAM`` and setting ``data.stream`` to the stream in the
+parent process, the child process can treat that stream as standard I/O. This
+can be used to implement something like CGI_.
+
+.. _CGI: https://en.wikipedia.org/wiki/Common_Gateway_Interface
+
+A sample CGI script/executable is:
+
+.. rubric:: cgi/tick.c
+.. literalinclude:: ../../code/cgi/tick.c
+    :language: c
+
+The CGI server combines the concepts from this chapter and :doc:`networking` so
+that every client is sent ten ticks after which that connection is closed.
+
+.. rubric:: cgi/main.c
+.. literalinclude:: ../../code/cgi/main.c
+    :language: c
+    :linenos:
+    :lines: 49-63
+    :emphasize-lines: 10
+
+Here we simply accept the TCP connection and pass on the socket (*stream*) to
+``invoke_cgi_script``.
+
+.. rubric:: cgi/main.c
+.. literalinclude:: ../../code/cgi/main.c
+    :language: c
+    :linenos:
+    :lines: 16, 25-45
+    :emphasize-lines: 8-9,18,20
+
+The ``stdout`` of the CGI script is set to the socket so that whatever our tick
+script prints, gets sent to the client. By using processes, we can offload the
+read/write buffering to the operating system, so in terms of convenience this
+is great. Just be warned that creating processes is a costly task.
+
+.. _pipes:
+
+Parent-child IPC
+----------------
+
+A parent and child can have one or two way communication over a pipe created by
+settings ``uv_stdio_container_t.flags`` to a bit-wise combination of
+``UV_CREATE_PIPE`` and ``UV_READABLE_PIPE`` or ``UV_WRITABLE_PIPE``. The
+read/write flag is from the perspective of the child process.  In this case,
+the ``uv_stream_t* stream`` field must be set to point to an initialized,
+unopened ``uv_pipe_t`` instance.
+
+New stdio Pipes
++++++++++++++++
+
+The ``uv_pipe_t`` structure represents more than just `pipe(7)`_ (or ``|``),
+but supports any streaming file-like objects. On Windows, the only object of
+that description is the `Named Pipe`_.  On Unix, this could be any of `Unix
+Domain Socket`_, or derived from `mkfifo(1)`_, or it could actually be a
+`pipe(7)`_.  When ``uv_spawn`` initializes a ``uv_pipe_t`` due to the
+`UV_CREATE_PIPE` flag, it opts for creating a `socketpair(2)`_.
+
+This is intended for the purpose of allowing multiple libuv processes to
+communicate with IPC. This is discussed below.
+
+.. _pipe(7): https://man7.org/linux/man-pages/man7/pipe.7.html
+.. _mkfifo(1): https://man7.org/linux/man-pages/man1/mkfifo.1.html
+.. _socketpair(2): https://man7.org/linux/man-pages/man2/socketpair.2.html
+.. _Unix Domain Socket: https://man7.org/linux/man-pages/man7/unix.7.html
+.. _Named Pipe: https://docs.microsoft.com/en-us/windows/win32/ipc/named-pipes
+
+
+Arbitrary process IPC
++++++++++++++++++++++
+
+Since domain sockets [#]_ can have a well known name and a location in the
+file-system they can be used for IPC between unrelated processes. The D-BUS_
+system used by open source desktop environments uses domain sockets for event
+notification. Various applications can then react when a contact comes online
+or new hardware is detected. The MySQL server also runs a domain socket on
+which clients can interact with it.
+
+.. _D-BUS: https://www.freedesktop.org/wiki/Software/dbus
+
+When using domain sockets, a client-server pattern is usually followed with the
+creator/owner of the socket acting as the server. After the initial setup,
+messaging is no different from TCP, so we'll re-use the echo server example.
+
+.. rubric:: pipe-echo-server/main.c
+.. literalinclude:: ../../code/pipe-echo-server/main.c
+    :language: c
+    :linenos:
+    :lines: 70-
+    :emphasize-lines: 5,10,14
+
+We name the socket ``echo.sock`` which means it will be created in the local
+directory. This socket now behaves no different from TCP sockets as far as
+the stream API is concerned. You can test this server using `socat`_::
+
+    $ socat - /path/to/socket
+
+A client which wants to connect to a domain socket will use::
+
+    void uv_pipe_connect(uv_connect_t *req, uv_pipe_t *handle, const char *name, uv_connect_cb cb);
+
+where ``name`` will be ``echo.sock`` or similar. On Unix systems, ``name`` must
+point to a valid file (e.g. ``/tmp/echo.sock``). On Windows, ``name`` follows a
+``\\?\pipe\echo.sock`` format.
+
+.. _socat: http://www.dest-unreach.org/socat/
+
+Sending file descriptors over pipes
++++++++++++++++++++++++++++++++++++
+
+The cool thing about domain sockets is that file descriptors can be exchanged
+between processes by sending them over a domain socket. This allows processes
+to hand off their I/O to other processes. Applications include load-balancing
+servers, worker processes and other ways to make optimum use of CPU. libuv only
+supports sending **TCP sockets or other pipes** over pipes for now.
+
+To demonstrate, we will look at a echo server implementation that hands of
+clients to worker processes in a round-robin fashion. This program is a bit
+involved, and while only snippets are included in the book, it is recommended
+to read the full code to really understand it.
+
+The worker process is quite simple, since the file-descriptor is handed over to
+it by the master.
+
+.. rubric:: multi-echo-server/worker.c
+.. literalinclude:: ../../code/multi-echo-server/worker.c
+    :language: c
+    :linenos:
+    :lines: 7-9,81-
+    :emphasize-lines: 6-8
+
+``queue`` is the pipe connected to the master process on the other end, along
+which new file descriptors get sent. It is important to set the ``ipc``
+argument of ``uv_pipe_init`` to 1 to indicate this pipe will be used for
+inter-process communication! Since the master will write the file handle to the
+standard input of the worker, we connect the pipe to ``stdin`` using
+``uv_pipe_open``.
+
+.. rubric:: multi-echo-server/worker.c
+.. literalinclude:: ../../code/multi-echo-server/worker.c
+    :language: c
+    :linenos:
+    :lines: 51-79
+    :emphasize-lines: 10,15,20
+
+First we call ``uv_pipe_pending_count()`` to ensure that a handle is available
+to read out. If your program could deal with different types of handles,
+``uv_pipe_pending_type()`` can be used to determine the type.
+Although ``accept`` seems odd in this code, it actually makes sense. What
+``accept`` traditionally does is get a file descriptor (the client) from
+another file descriptor (The listening socket). Which is exactly what we do
+here. Fetch the file descriptor (``client``) from ``queue``. From this point
+the worker does standard echo server stuff.
+
+Turning now to the master, let's take a look at how the workers are launched to
+allow load balancing.
+
+.. rubric:: multi-echo-server/main.c
+.. literalinclude:: ../../code/multi-echo-server/main.c
+    :language: c
+    :linenos:
+    :lines: 9-13
+
+The ``child_worker`` structure wraps the process, and the pipe between the
+master and the individual process.
+
+.. rubric:: multi-echo-server/main.c
+.. literalinclude:: ../../code/multi-echo-server/main.c
+    :language: c
+    :linenos:
+    :lines: 51,61-95
+    :emphasize-lines: 17,20-21
+
+In setting up the workers, we use the nifty libuv function ``uv_cpu_info`` to
+get the number of CPUs so we can launch an equal number of workers. Again it is
+important to initialize the pipe acting as the IPC channel with the third
+argument as 1. We then indicate that the child process' ``stdin`` is to be
+a readable pipe (from the point of view of the child). Everything is
+straightforward till here. The workers are launched and waiting for file
+descriptors to be written to their standard input.
+
+It is in ``on_new_connection`` (the TCP infrastructure is initialized in
+``main()``), that we accept the client socket and pass it along to the next
+worker in the round-robin.
+
+.. rubric:: multi-echo-server/main.c
+.. literalinclude:: ../../code/multi-echo-server/main.c
+    :language: c
+    :linenos:
+    :lines: 31-49
+    :emphasize-lines: 9,12-13
+
+The ``uv_write2`` call handles all the abstraction and it is simply a matter of
+passing in the handle (``client``) as the right argument. With this our
+multi-process echo server is operational.
+
+Thanks to Kyle for `pointing out`_ that ``uv_write2()`` requires a non-empty
+buffer even when sending handles.

+Threads
+=======
+
+Wait a minute? Why are we on threads? Aren't event loops supposed to be **the
+way** to do *web-scale programming*? Well... no. Threads are still the medium in
+which processors do their jobs. Threads are therefore mighty useful sometimes, even
+though you might have to wade through various synchronization primitives.
+
+Threads are used internally to fake the asynchronous nature of all of the system
+calls. libuv also uses threads to allow you, the application, to perform a task
+asynchronously that is actually blocking, by spawning a thread and collecting
+the result when it is done.
+
+Today there are two predominant thread libraries: the Windows threads
+implementation and POSIX's :man:`pthreads(7)`. libuv's thread API is analogous to
+the pthreads API and often has similar semantics.
+
+A notable aspect of libuv's thread facilities is that it is a self contained
+section within libuv. Whereas other features intimately depend on the event
+loop and callback principles, threads are complete agnostic, they block as
+required, signal errors directly via return values, and, as shown in the
+:ref:`first example <thread-create-example>`, don't even require a running
+event loop.
+
+libuv's thread API is also very limited since the semantics and syntax of
+threads are different on all platforms, with different levels of completeness.
+
+This chapter makes the following assumption: **There is only one event loop,
+running in one thread (the main thread)**. No other thread interacts
+with the event loop (except using ``uv_async_send``).
+
+Core thread operations
+----------------------
+
+There isn't much here, you just start a thread using ``uv_thread_create()`` and
+wait for it to close using ``uv_thread_join()``.
+
+.. _thread-create-example:
+
+.. rubric:: thread-create/main.c
+.. literalinclude:: ../../code/thread-create/main.c
+    :language: c
+    :linenos:
+    :lines: 26-36
+    :emphasize-lines: 3-7
+
+.. tip::
+
+    ``uv_thread_t`` is just an alias for ``pthread_t`` on Unix, but this is an
+    implementation detail, avoid depending on it to always be true.
+
+The second parameter is the function which will serve as the entry point for
+the thread, the last parameter is a ``void *`` argument which can be used to pass
+custom parameters to the thread. The function ``hare`` will now run in a separate
+thread, scheduled pre-emptively by the operating system:
+
+.. rubric:: thread-create/main.c
+.. literalinclude:: ../../code/thread-create/main.c
+    :language: c
+    :linenos:
+    :lines: 6-14
+    :emphasize-lines: 2
+
+Unlike ``pthread_join()`` which allows the target thread to pass back a value to
+the calling thread using a second parameter, ``uv_thread_join()`` does not. To
+send values use :ref:`inter-thread-communication`.
+
+Synchronization Primitives
+--------------------------
+
+This section is purposely spartan. This book is not about threads, so I only
+catalogue any surprises in the libuv APIs here. For the rest you can look at
+the :man:`pthreads(7)` man pages.
+
+Mutexes
+~~~~~~~
+
+The mutex functions are a **direct** map to the pthread equivalents.
+
+.. rubric:: libuv mutex functions
+.. code-block:: c
+
+    int uv_mutex_init(uv_mutex_t* handle);
+    int uv_mutex_init_recursive(uv_mutex_t* handle);
+    void uv_mutex_destroy(uv_mutex_t* handle);
+    void uv_mutex_lock(uv_mutex_t* handle);
+    int uv_mutex_trylock(uv_mutex_t* handle);
+    void uv_mutex_unlock(uv_mutex_t* handle);
+
+The ``uv_mutex_init()``, ``uv_mutex_init_recursive()`` and ``uv_mutex_trylock()``
+functions will return 0 on success, and an error code otherwise.
+
+If `libuv` has been compiled with debugging enabled, ``uv_mutex_destroy()``,
+``uv_mutex_lock()`` and ``uv_mutex_unlock()`` will ``abort()`` on error.
+Similarly ``uv_mutex_trylock()`` will abort if the error is anything *other
+than* ``EAGAIN`` or ``EBUSY``.
+
+Recursive mutexes are supported, but you should not rely on them. Also, they
+should not be used with ``uv_cond_t`` variables.
+
+The default BSD mutex implementation will raise an error if a thread which has
+locked a mutex attempts to lock it again. For example, a construct like::
+
+    uv_mutex_init(a_mutex);
+    uv_mutex_lock(a_mutex);
+    uv_thread_create(thread_id, entry, (void *)a_mutex);
+    uv_mutex_lock(a_mutex);
+    // more things here
+
+can be used to wait until another thread initializes some stuff and then
+unlocks ``a_mutex`` but will lead to your program crashing if in debug mode, or
+return an error in the second call to ``uv_mutex_lock()``.
+
+.. note::
+
+    Mutexes on Windows are always recursive.
+
+Locks
+~~~~~
+
+Read-write locks are a more granular access mechanism. Two readers can access
+shared memory at the same time. A writer may not acquire the lock when it is
+held by a reader. A reader or writer may not acquire a lock when a writer is
+holding it. Read-write locks are frequently used in databases. Here is a toy
+example.
+
+.. rubric:: locks/main.c - simple rwlocks
+.. literalinclude:: ../../code/locks/main.c
+    :language: c
+    :linenos:
+    :emphasize-lines: 13,16,27,31,42,55
+
+Run this and observe how the readers will sometimes overlap. In case of
+multiple writers, schedulers will usually give them higher priority, so if you
+add two writers, you'll see that both writers tend to finish first before the
+readers get a chance again.
+
+We also use barriers in the above example so that the main thread can wait for
+all readers and writers to indicate they have ended.

+
+libuv also supports semaphores_, `condition variables`_ and barriers_ with APIs
+very similar to their pthread counterparts.
+
+.. _semaphores: https://en.wikipedia.org/wiki/Semaphore_(programming)
+.. _condition variables: https://en.wikipedia.org/wiki/Monitor_(synchronization)#Condition_variables_2
+.. _barriers: https://en.wikipedia.org/wiki/Barrier_(computer_science)
+
+In addition, libuv provides a convenience function ``uv_once()``. Multiple
+threads can attempt to call ``uv_once()`` with a given guard and a function
+pointer, **only the first one will win, the function will be called once and
+only once**::
+
+    /* Initialize guard */
+    static uv_once_t once_only = UV_ONCE_INIT;
+
+    int i = 0;
+
+    void increment() {
+        i++;
+    }
+
+    void thread1() {
+        /* ... work */
+        uv_once(once_only, increment);
+    }
+
+    void thread2() {
+        /* ... work */
+        uv_once(once_only, increment);
+    }
+
+    int main() {
+        /* ... spawn threads */
+    }
+
+After all threads are done, ``i == 1``.
+
+.. _libuv-work-queue:
+
+libuv v0.11.11 onwards also added a ``uv_key_t`` struct and api_ for
+thread-local storage.

+
+libuv work queue
+----------------
+
+``uv_queue_work()`` is a convenience function that allows an application to run
+a task in a separate thread, and have a callback that is triggered when the
+task is done. A seemingly simple function, what makes ``uv_queue_work()``
+tempting is that it allows potentially any third-party libraries to be used
+with the event-loop paradigm. When you use event loops, it is *imperative to
+make sure that no function which runs periodically in the loop thread blocks
+when performing I/O or is a serious CPU hog*, because this means that the loop
+slows down and events are not being handled at full capacity.
+
+However, a lot of existing code out there features blocking functions (for example
+a routine which performs I/O under the hood) to be used with threads if you
+want responsiveness (the classic 'one thread per client' server model), and
+getting them to play with an event loop library generally involves rolling your
+own system of running the task in a separate thread.  libuv just provides
+a convenient abstraction for this.
+
+Here is a simple example inspired by `node.js is cancer`_. We are going to
+calculate fibonacci numbers, sleeping a bit along the way, but run it in
+a separate thread so that the blocking and CPU bound task does not prevent the
+event loop from performing other activities.
+
+.. rubric:: queue-work/main.c - lazy fibonacci
+.. literalinclude:: ../../code/queue-work/main.c
+    :language: c
+    :linenos:
+    :lines: 17-29
+
+The actual task function is simple, nothing to show that it is going to be
+run in a separate thread. The ``uv_work_t`` structure is the clue. You can pass
+arbitrary data through it using the ``void* data`` field and use it to
+communicate to and from the thread. But be sure you are using proper locks if
+you are changing things while both threads may be running.
+
+The trigger is ``uv_queue_work``:
+
+.. rubric:: queue-work/main.c
+.. literalinclude:: ../../code/queue-work/main.c
+    :language: c
+    :linenos:
+    :lines: 31-44
+    :emphasize-lines: 10
+
+The thread function will be launched in a separate thread, passed the
+``uv_work_t`` structure and once the function returns, the *after* function
+will be called on the thread the event loop is running in. It will be passed
+the same structure.
+
+For writing wrappers to blocking libraries, a common :ref:`pattern <baton>`
+is to use a baton to exchange data.
+
+Since libuv version `0.9.4` an additional function, ``uv_cancel()``, is
+available. This allows you to cancel tasks on the libuv work queue. Only tasks
+that *are yet to be started* can be cancelled. If a task has *already started
+executing, or it has finished executing*, ``uv_cancel()`` **will fail**.
+
+``uv_cancel()`` is useful to cleanup pending tasks if the user requests
+termination. For example, a music player may queue up multiple directories to
+be scanned for audio files. If the user terminates the program, it should quit
+quickly and not wait until all pending requests are run.
+
+Let's modify the fibonacci example to demonstrate ``uv_cancel()``. We first set
+up a signal handler for termination.
+
+.. rubric:: queue-cancel/main.c
+.. literalinclude:: ../../code/queue-cancel/main.c
+    :language: c
+    :linenos:
+    :lines: 43-
+
+When the user triggers the signal by pressing ``Ctrl+C`` we send
+``uv_cancel()`` to all the workers. ``uv_cancel()`` will return ``0`` for those that are already executing or finished.
+
+.. rubric:: queue-cancel/main.c
+.. literalinclude:: ../../code/queue-cancel/main.c
+    :language: c
+    :linenos:
+    :lines: 33-41
+    :emphasize-lines: 6
+
+For tasks that do get cancelled successfully, the *after* function is called
+with ``status`` set to ``UV_ECANCELED``.
+
+.. rubric:: queue-cancel/main.c
+.. literalinclude:: ../../code/queue-cancel/main.c
+    :language: c
+    :linenos:
+    :lines: 28-31
+    :emphasize-lines: 2
+
+``uv_cancel()`` can also be used with ``uv_fs_t`` and ``uv_getaddrinfo_t``
+requests. For the filesystem family of functions, ``uv_fs_t.errorno`` will be
+set to ``UV_ECANCELED``.
+
+.. TIP::
+
+    A well designed program would have a way to terminate long running workers
+    that have already started executing. Such a worker could periodically check
+    for a variable that only the main process sets to signal termination.
+
+.. _inter-thread-communication:
+
+Inter-thread communication
+--------------------------
+
+Sometimes you want various threads to actually send each other messages *while*
+they are running. For example you might be running some long duration task in
+a separate thread (perhaps using ``uv_queue_work``) but want to notify progress
+to the main thread. This is a simple example of having a download manager
+informing the user of the status of running downloads.
+
+.. rubric:: progress/main.c
+.. literalinclude:: ../../code/progress/main.c
+    :language: c
+    :linenos:
+    :lines: 7-8,35-
+    :emphasize-lines: 2,11
+
+The async thread communication works *on loops* so although any thread can be
+the message sender, only threads with libuv loops can be receivers (or rather
+the loop is the receiver). libuv will invoke the callback (``print_progress``)
+with the async watcher whenever it receives a message.
+
+.. warning::
+
+    It is important to realize that since the message send is *async*, the callback
+    may be invoked immediately after ``uv_async_send`` is called in another
+    thread, or it may be invoked after some time. libuv may also combine
+    multiple calls to ``uv_async_send`` and invoke your callback only once. The
+    only guarantee that libuv makes is -- The callback function is called *at
+    least once* after the call to ``uv_async_send``. If you have no pending
+    calls to ``uv_async_send``, the callback won't be called. If you make two
+    or more calls, and libuv hasn't had a chance to run the callback yet, it
+    *may* invoke your callback *only once* for the multiple invocations of
+    ``uv_async_send``. Your callback will never be called twice for just one
+    event.
+
+.. rubric:: progress/main.c
+.. literalinclude:: ../../code/progress/main.c
+    :language: c
+    :linenos:
+    :lines: 10-24
+    :emphasize-lines: 7-8
+
+In the download function, we modify the progress indicator and queue the message
+for delivery with ``uv_async_send``. Remember: ``uv_async_send`` is also
+non-blocking and will return immediately.
+
+.. rubric:: progress/main.c
+.. literalinclude:: ../../code/progress/main.c
+    :language: c
+    :linenos:
+    :lines: 31-34
+
+The callback is a standard libuv pattern, extracting the data from the watcher.
+
+Finally it is important to remember to clean up the watcher.
+
+.. rubric:: progress/main.c
+.. literalinclude:: ../../code/progress/main.c
+    :language: c
+    :linenos:
+    :lines: 26-29
+    :emphasize-lines: 3
+
+After this example, which showed the abuse of the ``data`` field, bnoordhuis_
+pointed out that using the ``data`` field is not thread safe, and
+``uv_async_send()`` is actually only meant to wake up the event loop. Use
+a mutex or rwlock to ensure accesses are performed in the right order.
+
+.. note::
+
+    mutexes and rwlocks **DO NOT** work inside a signal handler, whereas
+    ``uv_async_send`` does.
+
+One use case where ``uv_async_send`` is required is when interoperating with
+libraries that require thread affinity for their functionality. For example in
+node.js, a v8 engine instance, contexts and its objects are bound to the thread
+that the v8 instance was started in. Interacting with v8 data structures from
+another thread can lead to undefined results. Now consider some node.js module
+which binds a third party library. It may go something like this:
+
+1. In node, the third party library is set up with a JavaScript callback to be
+   invoked for more information::
+
+    var lib = require('lib');
+    lib.on_progress(function() {
+        console.log("Progress");
+    });
+
+    lib.do();
+
+    // do other stuff
+
+2. ``lib.do`` is supposed to be non-blocking but the third party lib is
+   blocking, so the binding uses ``uv_queue_work``.
+
+3. The actual work being done in a separate thread wants to invoke the progress
+   callback, but cannot directly call into v8 to interact with JavaScript. So
+   it uses ``uv_async_send``.
+
+4. The async callback, invoked in the main loop thread, which is the v8 thread,
+   then interacts with v8 to invoke the JavaScript callback.

+Utilities
+=========
+
+This chapter catalogues tools and techniques which are useful for common tasks.
+The `libev man page`_ already covers some patterns which can be adopted to
+libuv through simple API changes. It also covers parts of the libuv API that
+don't require entire chapters dedicated to them.
+
+Timers
+------
+
+Timers invoke the callback after a certain time has elapsed since the timer was
+started. libuv timers can also be set to invoke at regular intervals instead of
+just once.
+
+Simple use is to init a watcher and start it with a ``timeout``, and optional ``repeat``.
+Timers can be stopped at any time.
+
+.. code-block:: c
+
+    uv_timer_t timer_req;
+
+    uv_timer_init(loop, &timer_req);
+    uv_timer_start(&timer_req, callback, 5000, 2000);
+
+will start a repeating timer, which first starts 5 seconds (the ``timeout``) after the execution
+of ``uv_timer_start``, then repeats every 2 seconds (the ``repeat``). Use:
+
+.. code-block:: c
+
+    uv_timer_stop(&timer_req);
+
+to stop the timer. This can be used safely from within the callback as well.
+
+The repeat interval can be modified at any time with::
+
+    uv_timer_set_repeat(uv_timer_t *timer, int64_t repeat);
+
+which will take effect **when possible**. If this function is called from
+a timer callback, it means:
+
+* If the timer was non-repeating, the timer has already been stopped. Use
+  ``uv_timer_start`` again.
+* If the timer is repeating, the next timeout has already been scheduled, so
+  the old repeat interval will be used once more before the timer switches to
+  the new interval.
+
+The utility function::
+
+    int uv_timer_again(uv_timer_t *)
+
+applies **only to repeating timers** and is equivalent to stopping the timer
+and then starting it with both initial ``timeout`` and ``repeat`` set to the
+old ``repeat`` value. If the timer hasn't been started it fails (error code
+``UV_EINVAL``) and returns -1.
+
+An actual timer example is in the :ref:`reference count section
+<reference-count>`.
+
+.. _reference-count:
+
+Event loop reference count
+--------------------------
+
+The event loop only runs as long as there are active handles. This system
+works by having every handle increase the reference count of the event loop
+when it is started and decreasing the reference count when stopped. It is also
+possible to manually change the reference count of handles using::
+
+    void uv_ref(uv_handle_t*);
+    void uv_unref(uv_handle_t*);
+
+These functions can be used to allow a loop to exit even when a watcher is
+active or to use custom objects to keep the loop alive.
+
+The latter can be used with interval timers. You might have a garbage collector
+which runs every X seconds, or your network service might send a heartbeat to
+others periodically, but you don't want to have to stop them along all clean
+exit paths or error scenarios. Or you want the program to exit when all your
+other watchers are done. In that case just unref the timer immediately after
+creation so that if it is the only watcher running then ``uv_run`` will still
+exit.
+
+This is also used in node.js where some libuv methods are being bubbled up to
+the JS API. A ``uv_handle_t`` (the superclass of all watchers) is created per
+JS object and can be ref/unrefed.
+
+.. rubric:: ref-timer/main.c
+.. literalinclude:: ../../code/ref-timer/main.c
+    :language: c
+    :linenos:
+    :lines: 5-8, 17-
+    :emphasize-lines: 9
+
+We initialize the garbage collector timer, then immediately ``unref`` it.
+Observe how after 9 seconds, when the fake job is done, the program
+automatically exits, even though the garbage collector is still running.
+
+Idler pattern
+-------------
+
+The callbacks of idle handles are invoked once per event loop. The idle
+callback can be used to perform some very low priority activity. For example,
+you could dispatch a summary of the daily application performance to the
+developers for analysis during periods of idleness, or use the application's
+CPU time to perform SETI calculations :) An idle watcher is also useful in
+a GUI application. Say you are using an event loop for a file download. If the
+TCP socket is still being established and no other events are present your
+event loop will pause (**block**), which means your progress bar will freeze
+and the user will face an unresponsive application. In such a case queue up and
+idle watcher to keep the UI operational.
+
+.. rubric:: idle-compute/main.c
+.. literalinclude:: ../../code/idle-compute/main.c
+    :language: c
+    :linenos:
+    :lines: 5-9, 34-
+    :emphasize-lines: 13
+
+Here we initialize the idle watcher and queue it up along with the actual
+events we are interested in. ``crunch_away`` will now be called repeatedly
+until the user types something and presses Return. Then it will be interrupted
+for a brief amount as the loop deals with the input data, after which it will
+keep calling the idle callback again.
+
+.. rubric:: idle-compute/main.c
+.. literalinclude:: ../../code/idle-compute/main.c
+    :language: c
+    :linenos:
+    :lines: 10-19
+
+.. _baton:
+
+Passing data to worker thread
+-----------------------------
+
+When using ``uv_queue_work`` you'll usually need to pass complex data through
+to the worker thread. The solution is to use a ``struct`` and set
+``uv_work_t.data`` to point to it. A slight variation is to have the
+``uv_work_t`` itself as the first member of this struct (called a baton [#]_).
+This allows cleaning up the work request and all the data in one free call.
+
+.. code-block:: c
+    :linenos:
+    :emphasize-lines: 2
+
+    struct ftp_baton {
+        uv_work_t req;
+        char *host;
+        int port;
+        char *username;
+        char *password;
+    }
+
+.. code-block:: c
+    :linenos:
+    :emphasize-lines: 2
+
+    ftp_baton *baton = (ftp_baton*) malloc(sizeof(ftp_baton));
+    baton->req.data = (void*) baton;
+    baton->host = strdup("my.webhost.com");
+    baton->port = 21;
+    // ...
+
+    uv_queue_work(loop, &baton->req, ftp_session, ftp_cleanup);
+
+Here we create the baton and queue the task.
+
+Now the task function can extract the data it needs:
+
+.. code-block:: c
+    :linenos:
+    :emphasize-lines: 2, 12
+
+    void ftp_session(uv_work_t *req) {
+        ftp_baton *baton = (ftp_baton*) req->data;
+
+        fprintf(stderr, "Connecting to %s\n", baton->host);
+    }
+
+    void ftp_cleanup(uv_work_t *req) {
+        ftp_baton *baton = (ftp_baton*) req->data;
+
+        free(baton->host);
+        // ...
+        free(baton);
+    }
+
+We then free the baton which also frees the watcher.
+
+External I/O with polling
+-------------------------
+
+Usually third-party libraries will handle their own I/O, and keep track of
+their sockets and other files internally. In this case it isn't possible to use
+the standard stream I/O operations, but the library can still be integrated
+into the libuv event loop. All that is required is that the library allow you
+to access the underlying file descriptors and provide functions that process
+tasks in small increments as decided by your application. Some libraries though
+will not allow such access, providing only a standard blocking function which
+will perform the entire I/O transaction and only then return. It is unwise to
+use these in the event loop thread, use the :ref:`threadpool` instead. Of
+course, this will also mean losing granular control on the library.
+
+The ``uv_poll`` section of libuv simply watches file descriptors using the
+operating system notification mechanism. In some sense, all the I/O operations
+that libuv implements itself are also backed by ``uv_poll`` like code. Whenever
+the OS notices a change of state in file descriptors being polled, libuv will
+invoke the associated callback.
+
+Here we will walk through a simple download manager that will use libcurl_ to
+download files. Rather than give all control to libcurl, we'll instead be
+using the libuv event loop, and use the non-blocking, async multi_ interface to
+progress with the download whenever libuv notifies of I/O readiness.

+    :lines: 1-9,142-
+    :emphasize-lines: 7,21,24-25
+
+The way each library is integrated with libuv will vary. In the case of
+libcurl, we can register two callbacks. The socket callback ``handle_socket``
+is invoked whenever the state of a socket changes and we have to start polling
+it. ``start_timeout`` is called by libcurl to notify us of the next timeout
+interval, after which we should drive libcurl forward regardless of I/O status.
+This is so that libcurl can handle errors or do whatever else is required to
+get the download moving.
+
+Our downloader is to be invoked as::
+
+    $ ./uvwget [url1] [url2] ...
+
+So we add each argument as a URL

+    :language: c
+    :linenos:
+    :lines: 39-56
+    :emphasize-lines: 13-14
+
+We let libcurl directly write the data to a file, but much more is possible if
+you so desire.
+
+``start_timeout`` will be called immediately the first time by libcurl, so
+things are set in motion. This simply starts a libuv `timer <#timers>`_ which
+drives ``curl_multi_socket_action`` with ``CURL_SOCKET_TIMEOUT`` whenever it
+times out. ``curl_multi_socket_action`` is what drives libcurl, and what we
+call whenever sockets change state. But before we go into that, we need to poll
+on sockets whenever ``handle_socket`` is called.
+
+.. rubric:: uvwget/main.c - Setting up polling
+.. literalinclude:: ../../code/uvwget/main.c
+    :language: c
+    :linenos:
+    :lines: 102-140
+    :emphasize-lines: 9,11,15,21,24
+
+We are interested in the socket fd ``s``, and the ``action``. For every socket
+we create a ``uv_poll_t`` handle if it doesn't exist, and associate it with the
+socket using ``curl_multi_assign``. This way ``socketp`` points to it whenever
+the callback is invoked.
+
+In the case that the download is done or fails, libcurl requests removal of the
+poll. So we stop and free the poll handle.
+
+Depending on what events libcurl wishes to watch for, we start polling with
+``UV_READABLE`` or ``UV_WRITABLE``. Now libuv will invoke the poll callback
+whenever the socket is ready for reading or writing. Calling ``uv_poll_start``
+multiple times on the same handle is acceptable, it will just update the events
+mask with the new value. ``curl_perform`` is the crux of this program.

+.. rubric:: uvwget/main.c - Driving libcurl.

+    :language: c
+    :linenos:
+    :lines: 81-95
+    :emphasize-lines: 2,6-7,12
+
+The first thing we do is to stop the timer, since there has been some progress
+in the interval. Then depending on what event triggered the callback, we set
+the correct flags. Then we call ``curl_multi_socket_action`` with the socket
+that progressed and the flags informing about what events happened. At this
+point libcurl does all of its internal tasks in small increments, and will
+attempt to return as fast as possible, which is exactly what an evented program
+wants in its main thread. libcurl keeps queueing messages into its own queue
+about transfer progress. In our case we are only interested in transfers that
+are completed. So we extract these messages, and clean up handles whose
+transfers are done.

+
+Loading libraries
+-----------------
+
+libuv provides a cross platform API to dynamically load `shared libraries`_.
+This can be used to implement your own plugin/extension/module system and is
+used by node.js to implement ``require()`` support for bindings. The usage is
+quite simple as long as your library exports the right symbols. Be careful with
+sanity and security checks when loading third party code, otherwise your
+program will behave unpredictably. This example implements a very simple
+plugin system which does nothing except print the name of the plugin.
+
+Let us first look at the interface provided to plugin authors.
+
+.. rubric:: plugin/plugin.h
+.. literalinclude:: ../../code/plugin/plugin.h
+    :language: c
+    :linenos:
+
+You can similarly add more functions that plugin authors can use to do useful
+things in your application [#]_. A sample plugin using this API is:
+
+.. rubric:: plugin/hello.c
+.. literalinclude:: ../../code/plugin/hello.c
+    :language: c
+    :linenos:
+
+Our interface defines that all plugins should have an ``initialize`` function
+which will be called by the application. This plugin is compiled as a shared
+library and can be loaded by running our application::
+

+    Loading libhello.dylib
+    Registered plugin "Hello World!"
+
+.. NOTE::
+
+    The shared library filename will be different depending on platforms. On
+    Linux it is ``libhello.so``.
+
+This is done by using ``uv_dlopen`` to first load the shared library
+``libhello.dylib``. Then we get access to the ``initialize`` function using
+``uv_dlsym`` and invoke it.

+
+``uv_dlopen`` expects a path to the shared library and sets the opaque
+``uv_lib_t`` pointer. It returns 0 on success, -1 on error. Use ``uv_dlerror``
+to get the error message.
+
+``uv_dlsym`` stores a pointer to the symbol in the second argument in the third
+argument. ``init_plugin_function`` is a function pointer to the sort of
+function we are looking for in the application's plugins.

+
+TTY
+---
+
+Text terminals have supported basic formatting for a long time, with a `pretty
+standardised`_ command set. This formatting is often used by programs to
+improve the readability of terminal output. For example ``grep --colour``.
+libuv provides the ``uv_tty_t`` abstraction (a stream) and related functions to
+implement the ANSI escape codes across all platforms. By this I mean that libuv
+converts ANSI codes to the Windows equivalent, and provides functions to get
+terminal information.
+
+.. _pretty standardised: https://en.wikipedia.org/wiki/ANSI_escape_sequences
+
+The first thing to do is to initialize a ``uv_tty_t`` with the file descriptor
+it reads/writes from. This is achieved with::
+
+    int uv_tty_init(uv_loop_t*, uv_tty_t*, uv_file fd, int unused)
+
+The ``unused`` parameter is now auto-detected and ignored. It previously needed
+to be set to use ``uv_read_start()`` on the stream.
+
+It is then best to use ``uv_tty_set_mode`` to set the mode to *normal*
+which enables most TTY formatting, flow-control and other settings. Other_ modes
+are also available.
+
+.. _Other: http://docs.libuv.org/en/v1.x/tty.html#c.uv_tty_mode_t
+
+Remember to call ``uv_tty_reset_mode`` when your program exits to restore the
+state of the terminal. Just good manners. Another set of good manners is to be
+aware of redirection. If the user redirects the output of your command to
+a file, control sequences should not be written as they impede readability and
+``grep``. To check if the file descriptor is indeed a TTY, call
+``uv_guess_handle`` with the file descriptor and compare the return value with
+``UV_TTY``.
+
+Here is a simple example which prints white text on a red background:
+
+.. rubric:: tty/main.c
+.. literalinclude:: ../../code/tty/main.c
+    :language: c
+    :linenos:
+    :emphasize-lines: 11-12,14,17,27
+
+The final TTY helper is ``uv_tty_get_winsize()`` which is used to get the
+width and height of the terminal and returns ``0`` on success. Here is a small
+program which does some animation using the function and character position
+escape codes.
+
+.. rubric:: tty-gravity/main.c
+.. literalinclude:: ../../code/tty-gravity/main.c
+    :language: c
+    :linenos:
+    :emphasize-lines: 19,25,38
+
+The escape codes are:
+
+======  =======================
+Code    Meaning
+======  =======================
+*2* J    Clear part of the screen, 2 is entire screen
+H        Moves cursor to certain position, default top-left
+*n* B    Moves cursor down by n lines
+*n* C    Moves cursor right by n columns
+m        Obeys string of display settings, in this case green background (40+2), white text (30+7)
+======  =======================
+
+As you can see this is very useful to produce nicely formatted output, or even
+console based arcade games if that tickles your fancy. For fancier control you
+can try `ncurses`_.
+
+.. _ncurses: https://www.gnu.org/software/ncurses/ncurses.html
+
+.. versionchanged:: 1.23.1: the `readable` parameter is now unused and ignored.
+                    The appropriate value will now be auto-detected from the kernel.

+.. _handle:
+
+:c:type:`uv_handle_t` --- Base handle
+=====================================
+
+`uv_handle_t` is the base type for all libuv handle types.
+
+Structures are aligned so that any libuv handle can be cast to `uv_handle_t`.
+All API functions defined here work with any handle type.
+
+Libuv handles are not movable. Pointers to handle structures passed to
+functions must remain valid for the duration of the requested operation. Take
+care when using stack allocated handles.
+
+Data types
+----------
+
+.. c:type:: uv_handle_t
+
+    The base libuv handle type.
+
+.. c:enum:: uv_handle_type
+
+    The kind of the libuv handle.
+
+    ::
+
+        typedef enum {
+          UV_UNKNOWN_HANDLE = 0,
+          UV_ASYNC,
+          UV_CHECK,
+          UV_FS_EVENT,
+          UV_FS_POLL,
+          UV_HANDLE,
+          UV_IDLE,
+          UV_NAMED_PIPE,
+          UV_POLL,
+          UV_PREPARE,
+          UV_PROCESS,
+          UV_STREAM,
+          UV_TCP,
+          UV_TIMER,
+          UV_TTY,
+          UV_UDP,
+          UV_SIGNAL,
+          UV_FILE,
+          UV_HANDLE_TYPE_MAX
+        } uv_handle_type;
+
+.. c:type:: uv_any_handle
+
+    Union of all handle types.
+
+.. c:type:: void (*uv_alloc_cb)(uv_handle_t* handle, size_t suggested_size, uv_buf_t* buf)
+
+    Type definition for callback passed to :c:func:`uv_read_start` and
+    :c:func:`uv_udp_recv_start`. The user must allocate memory and fill the supplied
+    :c:type:`uv_buf_t` structure. If NULL is assigned as the buffer's base or 0 as its length,
+    a ``UV_ENOBUFS`` error will be triggered in the :c:type:`uv_udp_recv_cb` or the
+    :c:type:`uv_read_cb` callback.
+
+    Each buffer is used only once and the user is responsible for freeing it in the
+    :c:type:`uv_udp_recv_cb` or the :c:type:`uv_read_cb` callback.
+
+    A suggested size (65536 at the moment in most cases) is provided, but it's just an indication,
+    not related in any way to the pending data to be read. The user is free to allocate the amount
+    of memory they decide.
+
+    As an example, applications with custom allocation schemes such as using freelists, allocation
+    pools or slab based allocators may decide to use a different size which matches the memory
+    chunks they already have.
+
+    Example:
+
+    ::
+
+        static void my_alloc_cb(uv_handle_t* handle, size_t suggested_size, uv_buf_t* buf) {
+          buf->base = malloc(suggested_size);
+          buf->len = suggested_size;
+        }
+
+.. c:type:: void (*uv_close_cb)(uv_handle_t* handle)
+
+    Type definition for callback passed to :c:func:`uv_close`.
+
+
+Public members
+^^^^^^^^^^^^^^
+
+.. c:member:: uv_loop_t* uv_handle_t.loop
+
+    Pointer to the :c:type:`uv_loop_t` the handle is running on. Readonly.
+
+.. c:member:: uv_handle_type uv_handle_t.type
+
+    The :c:type:`uv_handle_type`, indicating the type of the underlying handle. Readonly.
+
+.. c:member:: void* uv_handle_t.data
+
+    Space for user-defined arbitrary data. libuv does not use this field.
+
+
+API
+---
+
+.. c:macro:: UV_HANDLE_TYPE_MAP(iter_macro)
+
+    Macro that expands to a series of invocations of `iter_macro` for
+    each of the handle types. `iter_macro` is invoked with two
+    arguments: the name of the `uv_handle_type` element without the
+    `UV_` prefix, and the name of the corresponding structure type
+    without the `uv_` prefix and `_t` suffix.
+
+.. c:function:: int uv_is_active(const uv_handle_t* handle)
+
+    Returns non-zero if the handle is active, zero if it's inactive. What
+    "active" means depends on the type of handle:
+
+    - A uv_async_t handle is always active and cannot be deactivated, except
+      by closing it with uv_close().
+
+    - A uv_pipe_t, uv_tcp_t, uv_udp_t, etc. handle - basically any handle that
+      deals with i/o - is active when it is doing something that involves i/o,
+      like reading, writing, connecting, accepting new connections, etc.
+
+    - A uv_check_t, uv_idle_t, uv_timer_t, etc. handle is active when it has
+      been started with a call to uv_check_start(), uv_idle_start(), etc.
+
+    Rule of thumb: if a handle of type `uv_foo_t` has a `uv_foo_start()`
+    function, then it's active from the moment that function is called.
+    Likewise, `uv_foo_stop()` deactivates the handle again.
+
+.. c:function:: int uv_is_closing(const uv_handle_t* handle)
+
+    Returns non-zero if the handle is closing or closed, zero otherwise.
+
+    .. note::
+        This function should only be used between the initialization of the handle and the
+        arrival of the close callback.
+
+.. c:function:: void uv_close(uv_handle_t* handle, uv_close_cb close_cb)
+
+    Request handle to be closed. `close_cb` will be called asynchronously after
+    this call. This MUST be called on each handle before memory is released.
+    Moreover, the memory can only be released in `close_cb` or after it has
+    returned.
+
+    Handles that wrap file descriptors are closed immediately but
+    `close_cb` will still be deferred to the next iteration of the event loop.
+    It gives you a chance to free up any resources associated with the handle.
+
+    In-progress requests, like uv_connect_t or uv_write_t, are cancelled and
+    have their callbacks called asynchronously with status=UV_ECANCELED.
+
+    `close_cb` can be `NULL` in cases where no cleanup or deallocation is
+    necessary.
+
+.. c:function:: void uv_ref(uv_handle_t* handle)
+
+    Reference the given handle. References are idempotent, that is, if a handle
+    is already referenced calling this function again will have no effect.
+
+    See :ref:`refcount`.
+
+.. c:function:: void uv_unref(uv_handle_t* handle)
+
+    Un-reference the given handle. References are idempotent, that is, if a handle
+    is not referenced calling this function again will have no effect.
+
+    See :ref:`refcount`.
+
+.. c:function:: int uv_has_ref(const uv_handle_t* handle)
+
+    Returns non-zero if the handle referenced, zero otherwise.
+
+    See :ref:`refcount`.
+
+.. c:function:: size_t uv_handle_size(uv_handle_type type)
+
+    Returns the size of the given handle type. Useful for FFI binding writers
+    who don't want to know the structure layout.
+
+
+Miscellaneous API functions
+---------------------------
+
+The following API functions take a :c:type:`uv_handle_t` argument but they work
+just for some handle types.
+
+.. c:function:: int uv_send_buffer_size(uv_handle_t* handle, int* value)
+
+    Gets or sets the size of the send buffer that the operating
+    system uses for the socket.
+
+    If `*value` == 0, then it will set `*value` to the current send buffer size.
+    If `*value` > 0 then it will use `*value` to set the new send buffer size.
+
+    On success, zero is returned. On error, a negative result is
+    returned.
+
+    This function works for TCP, pipe and UDP handles on Unix and for TCP and
+    UDP handles on Windows.
+
+    .. note::
+        Linux will set double the size and return double the size of the original set value.
+
+.. c:function:: int uv_recv_buffer_size(uv_handle_t* handle, int* value)
+
+    Gets or sets the size of the receive buffer that the operating
+    system uses for the socket.
+
+    If `*value` == 0, then it will set `*value` to the current receive buffer size.
+    If `*value` > 0 then it will use `*value` to set the new receive buffer size.
+
+    On success, zero is returned. On error, a negative result is
+    returned.
+
+    This function works for TCP, pipe and UDP handles on Unix and for TCP and
+    UDP handles on Windows.
+
+    .. note::
+        Linux will set double the size and return double the size of the original set value.
+
+.. c:function:: int uv_fileno(const uv_handle_t* handle, uv_os_fd_t* fd)
+
+    Gets the platform dependent file descriptor equivalent.
+
+    The following handles are supported: TCP, pipes, TTY, UDP and poll. Passing
+    any other handle type will fail with `UV_EINVAL`.
+
+    If a handle doesn't have an attached file descriptor yet or the handle
+    itself has been closed, this function will return `UV_EBADF`.
+
+    .. warning::
+        Be very careful when using this function. libuv assumes it's in control of the file
+        descriptor so any change to it may lead to malfunction.
+
+.. c:function:: uv_loop_t* uv_handle_get_loop(const uv_handle_t* handle)
+
+    Returns `handle->loop`.
+
+    .. versionadded:: 1.19.0
+
+.. c:function:: void* uv_handle_get_data(const uv_handle_t* handle)
+
+    Returns `handle->data`.
+
+    .. versionadded:: 1.19.0
+
+.. c:function:: void* uv_handle_set_data(uv_handle_t* handle, void* data)
+
+    Sets `handle->data` to `data`.
+
+    .. versionadded:: 1.19.0
+
+.. c:function:: uv_handle_type uv_handle_get_type(const uv_handle_t* handle)
+
+    Returns `handle->type`.
+
+    .. versionadded:: 1.19.0
+
+.. c:function:: const char* uv_handle_type_name(uv_handle_type type)
+
+    Returns the name for the equivalent struct for a given handle type,
+    e.g. `"pipe"` (as in :c:type:`uv_pipe_t`) for `UV_NAMED_PIPE`.
+
+    If no such handle type exists, this returns `NULL`.
+
+    .. versionadded:: 1.19.0
+
+.. _refcount:
+
+Reference counting
+------------------
+
+The libuv event loop (if run in the default mode) will run until there are no
+active `and` referenced handles left. The user can force the loop to exit early
+by unreferencing handles which are active, for example by calling :c:func:`uv_unref`
+after calling :c:func:`uv_timer_start`.
+
+A handle can be referenced or unreferenced, the refcounting scheme doesn't use
+a counter, so both operations are idempotent.
+
+All handles are referenced when active by default, see :c:func:`uv_is_active`
+for a more detailed explanation on what being `active` involves.

+==================================

+^^^^^^^^^^^^^^
+
+.. c:member:: void* uv_loop_t.data
+
+    Space for user-defined arbitrary data. libuv does not use and does not
+    touch this field.
+
+
+API
+---
+
+.. c:function:: int uv_loop_init(uv_loop_t* loop)
+
+    Initializes the given `uv_loop_t` structure.
+
+.. c:function:: int uv_loop_configure(uv_loop_t* loop, uv_loop_option option, ...)
+
+    .. versionadded:: 1.0.2
+
+    Set additional loop options.  You should normally call this before the
+    first call to :c:func:`uv_run` unless mentioned otherwise.
+
+    Returns 0 on success or a UV_E* error code on failure.  Be prepared to
+    handle UV_ENOSYS; it means the loop option is not supported by the platform.
+
+    Supported options:
+
+    - UV_LOOP_BLOCK_SIGNAL: Block a signal when polling for new events.  The
+      second argument to :c:func:`uv_loop_configure` is the signal number.
+
+      This operation is currently only implemented for SIGPROF signals,
+      to suppress unnecessary wakeups when using a sampling profiler.
+      Requesting other signals will fail with UV_EINVAL.
+
+    - UV_METRICS_IDLE_TIME: Accumulate the amount of idle time the event loop
+      spends in the event provider.
+
+      This option is necessary to use :c:func:`uv_metrics_idle_time`.
+
+    .. versionchanged:: 1.39.0 added the UV_METRICS_IDLE_TIME option.
+
+.. c:function:: int uv_loop_close(uv_loop_t* loop)
+
+    Releases all internal loop resources. Call this function only when the loop
+    has finished executing and all open handles and requests have been closed,
+    or it will return UV_EBUSY. After this function returns, the user can free
+    the memory allocated for the loop.
+
+.. c:function:: uv_loop_t* uv_default_loop(void)
+
+    Returns the initialized default loop. It may return NULL in case of
+    allocation failure.
+
+    This function is just a convenient way for having a global loop throughout
+    an application, the default loop is in no way different than the ones
+    initialized with :c:func:`uv_loop_init`. As such, the default loop can (and
+    should) be closed with :c:func:`uv_loop_close` so the resources associated
+    with it are freed.
+
+    .. warning::
+        This function is not thread safe.
+
+.. c:function:: int uv_run(uv_loop_t* loop, uv_run_mode mode)
+
+    This function runs the event loop. It will act differently depending on the
+    specified mode:
+
+    - UV_RUN_DEFAULT: Runs the event loop until there are no more active and
+      referenced handles or requests. Returns non-zero if :c:func:`uv_stop`
+      was called and there are still active handles or requests.  Returns
+      zero in all other cases.
+    - UV_RUN_ONCE: Poll for i/o once. Note that this function blocks if
+      there are no pending callbacks. Returns zero when done (no active handles
+      or requests left), or non-zero if more callbacks are expected (meaning
+      you should run the event loop again sometime in the future).
+    - UV_RUN_NOWAIT: Poll for i/o once but don't block if there are no
+      pending callbacks. Returns zero if done (no active handles
+      or requests left), or non-zero if more callbacks are expected (meaning
+      you should run the event loop again sometime in the future).
+
+    :c:func:`uv_run` is not reentrant. It must not be called from a callback.
+
+.. c:function:: int uv_loop_alive(const uv_loop_t* loop)
+
+    Returns non-zero if there are referenced active handles, active
+    requests or closing handles in the loop.
+
+.. c:function:: void uv_stop(uv_loop_t* loop)
+
+    Stop the event loop, causing :c:func:`uv_run` to end as soon as
+    possible. This will happen not sooner than the next loop iteration.
+    If this function was called before blocking for i/o, the loop won't block
+    for i/o on this iteration.
+
+.. c:function:: size_t uv_loop_size(void)
+
+    Returns the size of the `uv_loop_t` structure. Useful for FFI binding
+    writers who don't want to know the structure layout.
+
+.. c:function:: int uv_backend_fd(const uv_loop_t* loop)
+
+    Get backend file descriptor. Only kqueue, epoll and event ports are
+    supported.
+
+    This can be used in conjunction with `uv_run(loop, UV_RUN_NOWAIT)` to
+    poll in one thread and run the event loop's callbacks in another see
+    test/test-embed.c for an example.
+
+    .. note::
+        Embedding a kqueue fd in another kqueue pollset doesn't work on all platforms. It's not
+        an error to add the fd but it never generates events.
+
+.. c:function:: int uv_backend_timeout(const uv_loop_t* loop)
+
+    Get the poll timeout. The return value is in milliseconds, or -1 for no
+    timeout.
+
+.. c:function:: uint64_t uv_now(const uv_loop_t* loop)
+
+    Return the current timestamp in milliseconds. The timestamp is cached at
+    the start of the event loop tick, see :c:func:`uv_update_time` for details
+    and rationale.
+
+    The timestamp increases monotonically from some arbitrary point in time.
+    Don't make assumptions about the starting point, you will only get
+    disappointed.
+
+    .. note::
+        Use :c:func:`uv_hrtime` if you need sub-millisecond granularity.
+
+.. c:function:: void uv_update_time(uv_loop_t* loop)
+
+    Update the event loop's concept of "now". Libuv caches the current time
+    at the start of the event loop tick in order to reduce the number of
+    time-related system calls.
+
+    You won't normally need to call this function unless you have callbacks
+    that block the event loop for longer periods of time, where "longer" is
+    somewhat subjective but probably on the order of a millisecond or more.
+
+.. c:function:: void uv_walk(uv_loop_t* loop, uv_walk_cb walk_cb, void* arg)
+
+    Walk the list of handles: `walk_cb` will be executed with the given `arg`.
+
+.. c:function:: int uv_loop_fork(uv_loop_t* loop)
+
+    .. versionadded:: 1.12.0
+
+    Reinitialize any kernel state necessary in the child process after
+    a :man:`fork(2)` system call.
+
+    Previously started watchers will continue to be started in the
+    child process.
+
+    It is necessary to explicitly call this function on every event
+    loop created in the parent process that you plan to continue to
+    use in the child, including the default loop (even if you don't
+    continue to use it in the parent). This function must be called
+    before calling :c:func:`uv_run` or any other API function using
+    the loop in the child. Failure to do so will result in undefined
+    behaviour, possibly including duplicate events delivered to both
+    parent and child or aborting the child process.
+
+    When possible, it is preferred to create a new loop in the child
+    process instead of reusing a loop created in the parent. New loops
+    created in the child process after the fork should not use this
+    function.
+
+    This function is not implemented on Windows, where it returns ``UV_ENOSYS``.
+
+    .. caution::
+
+       This function is experimental. It may contain bugs, and is subject to
+       change or removal. API and ABI stability is not guaranteed.
+
+    .. note::
+
+        On Mac OS X, if directory FS event handles were in use in the
+        parent process *for any event loop*, the child process will no
+        longer be able to use the most efficient FSEvent
+        implementation. Instead, uses of directory FS event handles in
+        the child will fall back to the same implementation used for
+        files and on other kqueue-based systems.
+
+    .. caution::
+
+       On AIX and SunOS, FS event handles that were already started in
+       the parent process at the time of forking will *not* deliver
+       events in the child process; they must be closed and restarted.
+       On all other platforms, they will continue to work normally
+       without any further intervention.
+
+    .. caution::
+
+       Any previous value returned from :c:func:`uv_backend_fd` is now
+       invalid. That function must be called again to determine the
+       correct backend file descriptor.
+
+.. c:function:: void* uv_loop_get_data(const uv_loop_t* loop)

+    Returns `loop->data`.

+
+libuv 0.10 -> 1.0.0 migration guide
+===================================
+
+Some APIs changed quite a bit throughout the 1.0.0 development process. Here
+is a migration guide for the most significant changes that happened after 0.10
+was released.
+
+
+Loop initialization and closing
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+In libuv 0.10 (and previous versions), loops were created with `uv_loop_new`, which
+allocated memory for a new loop and initialized it; and destroyed with `uv_loop_delete`,
+which destroyed the loop and freed the memory. Starting with 1.0, those are deprecated
+and the user is responsible for allocating the memory and then initializing the loop.
+
+libuv 0.10
+
+::
+
+    uv_loop_t* loop = uv_loop_new();
+    ...
+    uv_loop_delete(loop);
+
+libuv 1.0
+
+::
+
+    uv_loop_t* loop = malloc(sizeof *loop);
+    uv_loop_init(loop);
+    ...
+    uv_loop_close(loop);
+    free(loop);
+
+.. note::
+    Error handling was omitted for brevity. Check the documentation for :c:func:`uv_loop_init`
+    and :c:func:`uv_loop_close`.
+
+
+Error handling
+~~~~~~~~~~~~~~
+
+Error handling had a major overhaul in libuv 1.0. In general, functions and status parameters
+would get 0 for success and -1 for failure on libuv 0.10, and the user had to use `uv_last_error`
+to fetch the error code, which was a positive number.
+
+In 1.0, functions and status parameters contain the actual error code, which is 0 for success, or
+a negative number in case of error.
+
+libuv 0.10
+
+::
+
+    ... assume 'server' is a TCP server which is already listening
+    r = uv_listen((uv_stream_t*) server, 511, NULL);
+    if (r == -1) {
+      uv_err_t err = uv_last_error(uv_default_loop());
+      /* err.code contains UV_EADDRINUSE */
+    }
+
+libuv 1.0
+
+::
+
+    ... assume 'server' is a TCP server which is already listening
+    r = uv_listen((uv_stream_t*) server, 511, NULL);
+    if (r < 0) {
+      /* r contains UV_EADDRINUSE */
+    }
+
+
+Threadpool changes
+~~~~~~~~~~~~~~~~~~
+
+In libuv 0.10 Unix used a threadpool which defaulted to 4 threads, while Windows used the
+`QueueUserWorkItem` API, which uses a Windows internal threadpool, which defaults to 512
+threads per process.
+
+In 1.0, we unified both implementations, so Windows now uses the same implementation Unix
+does. The threadpool size can be set by exporting the ``UV_THREADPOOL_SIZE`` environment
+variable. See :c:ref:`threadpool`.
+
+
+Allocation callback API change
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+In libuv 0.10 the callback had to return a filled :c:type:`uv_buf_t` by value:
+
+::
+
+    uv_buf_t alloc_cb(uv_handle_t* handle, size_t size) {
+        return uv_buf_init(malloc(size), size);
+    }
+
+In libuv 1.0 a pointer to a buffer is passed to the callback, which the user
+needs to fill:
+
+::
+
+    void alloc_cb(uv_handle_t* handle, size_t size, uv_buf_t* buf) {
+        buf->base = malloc(size);
+        buf->len = size;
+    }
+
+
+Unification of IPv4 / IPv6 APIs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+libuv 1.0 unified the IPv4 and IPv6 APIS. There is no longer a `uv_tcp_bind` and `uv_tcp_bind6`
+duality, there is only :c:func:`uv_tcp_bind` now.
+
+IPv4 functions took ``struct sockaddr_in`` structures by value, and IPv6 functions took
+``struct sockaddr_in6``. Now functions take a ``struct sockaddr*`` (note it's a pointer).
+It can be stack allocated.
+
+libuv 0.10
+
+::
+
+    struct sockaddr_in addr = uv_ip4_addr("0.0.0.0", 1234);
+    ...
+    uv_tcp_bind(&server, addr)
+
+libuv 1.0
+
+::
+
+    struct sockaddr_in addr;
+    uv_ip4_addr("0.0.0.0", 1234, &addr)
+    ...
+    uv_tcp_bind(&server, (const struct sockaddr*) &addr, 0);
+
+The IPv4 and IPv6 struct creating functions (:c:func:`uv_ip4_addr` and :c:func:`uv_ip6_addr`)
+have also changed, make sure you check the documentation.
+
+..note::
+    This change applies to all functions that made a distinction between IPv4 and IPv6
+    addresses.
+
+
+Streams / UDP  data receive callback API change
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The streams and UDP data receive callbacks now get a pointer to a :c:type:`uv_buf_t` buffer,
+not a structure by value.
+
+libuv 0.10
+
+::
+
+    void on_read(uv_stream_t* handle,
+                 ssize_t nread,
+                 uv_buf_t buf) {
+        ...
+    }
+
+    void recv_cb(uv_udp_t* handle,
+                 ssize_t nread,
+                 uv_buf_t buf,
+                 struct sockaddr* addr,
+                 unsigned flags) {
+        ...
+    }
+
+libuv 1.0
+
+::
+
+    void on_read(uv_stream_t* handle,
+                 ssize_t nread,
+                 const uv_buf_t* buf) {
+        ...
+    }
+
+    void recv_cb(uv_udp_t* handle,
+                 ssize_t nread,
+                 const uv_buf_t* buf,
+                 const struct sockaddr* addr,
+                 unsigned flags) {
+        ...
+    }
+
+
+Receiving handles over pipes API change
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+In libuv 0.10 (and earlier versions) the `uv_read2_start` function was used to start reading
+data on a pipe, which could also result in the reception of handles over it. The callback
+for such function looked like this:
+
+::
+
+    void on_read(uv_pipe_t* pipe,
+                 ssize_t nread,
+                 uv_buf_t buf,
+                 uv_handle_type pending) {
+        ...
+    }
+
+In libuv 1.0, `uv_read2_start` was removed, and the user needs to check if there are pending
+handles using :c:func:`uv_pipe_pending_count` and :c:func:`uv_pipe_pending_type` while in
+the read callback:
+
+::
+
+    void on_read(uv_stream_t* handle,
+                 ssize_t nread,
+                 const uv_buf_t* buf) {
+        ...
+        while (uv_pipe_pending_count((uv_pipe_t*) handle) != 0) {
+            pending = uv_pipe_pending_type((uv_pipe_t*) handle);
+            ...
+        }
+        ...
+    }
+
+
+Extracting the file descriptor out of a handle
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+While it wasn't supported by the API, users often accessed the libuv internals in
+order to get access to the file descriptor of a TCP handle, for example.
+
+::
+
+    fd = handle->io_watcher.fd;
+
+This is now properly exposed through the :c:func:`uv_fileno` function.
+
+
+uv_fs_readdir rename and API change
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+`uv_fs_readdir` returned a list of strings in the `req->ptr` field upon completion in
+libuv 0.10. In 1.0, this function got renamed to :c:func:`uv_fs_scandir`, since it's
+actually implemented using ``scandir(3)``.
+
+In addition, instead of allocating a full list strings, the user is able to get one
+result at a time by using the :c:func:`uv_fs_scandir_next` function. This function
+does not need to make a roundtrip to the threadpool, because libuv will keep the
+list of *dents* returned by ``scandir(3)`` around.

+
+.. c:function:: int uv_if_indextoname(unsigned int ifindex, char* buffer, size_t* size)
+
+    IPv6-capable implementation of :man:`if_indextoname(3)`. When called,
+    `*size` indicates the length of the `buffer`, which is used to store the
+    result.
+    On success, zero is returned, `buffer` contains the interface name, and
+    `*size` represents the string length of the `buffer`, excluding the NUL
+    terminator byte from `*size`. On error, a negative result is
+    returned. If `buffer` is not large enough to hold the result,
+    `UV_ENOBUFS` is returned, and `*size` represents the necessary size in
+    bytes, including the NUL terminator byte into the `*size`.
+
+    On Unix, the returned interface name can be used directly as an
+    interface identifier in scoped IPv6 addresses, e.g.
+    `fe80::abc:def1:2345%en0`.
+
+    On Windows, the returned interface cannot be used as an interface
+    identifier, as Windows uses numerical interface identifiers, e.g.
+    `fe80::abc:def1:2345%5`.
+
+    To get an interface identifier in a cross-platform compatible way,
+    use `uv_if_indextoiid()`.
+
+    Example:
+
+    ::
+
+        char ifname[UV_IF_NAMESIZE];
+        size_t size = sizeof(ifname);
+        uv_if_indextoname(sin6->sin6_scope_id, ifname, &size);
+
+    .. versionadded:: 1.16.0
+
+.. c:function:: int uv_if_indextoiid(unsigned int ifindex, char* buffer, size_t* size)
+
+    Retrieves a network interface identifier suitable for use in an IPv6 scoped
+    address. On Windows, returns the numeric `ifindex` as a string. On all other
+    platforms, `uv_if_indextoname()` is called. The result is written to
+    `buffer`, with `*size` indicating the length of `buffer`. If `buffer` is not
+    large enough to hold the result, then `UV_ENOBUFS` is returned, and `*size`
+    represents the size, including the NUL byte, required to hold the
+    result.

+
+.. c:function:: int uv_cwd(char* buffer, size_t* size)
+
+    Gets the current working directory, and stores it in `buffer`. If the

+    returns `UV_ENOBUFS`, and sets `size` to the required length, including the
+    null terminator.
+
+    .. versionchanged:: 1.1.0
+
+        On Unix the path no longer ends in a slash.
+
+    .. versionchanged:: 1.9.0 the returned length includes the terminating null

+
+.. c:function:: int uv_os_homedir(char* buffer, size_t* size)
+
+    Gets the current user's home directory. On Windows, `uv_os_homedir()` first
+    checks the `USERPROFILE` environment variable using
+    `GetEnvironmentVariableW()`. If `USERPROFILE` is not set,
+    `GetUserProfileDirectoryW()` is called. On all other operating systems,
+    `uv_os_homedir()` first checks the `HOME` environment variable using
+    :man:`getenv(3)`. If `HOME` is not set, :man:`getpwuid_r(3)` is called. The
+    user's home directory is stored in `buffer`. When `uv_os_homedir()` is
+    called, `size` indicates the maximum size of `buffer`. On success `size` is set
+    to the string length of `buffer`. On `UV_ENOBUFS` failure `size` is set to the
+    required length for `buffer`, including the null byte.

+
+    .. versionadded:: 1.6.0
+
+.. c:function:: int uv_os_tmpdir(char* buffer, size_t* size)
+
+    Gets the temp directory. On Windows, `uv_os_tmpdir()` uses `GetTempPathW()`.
+    On all other operating systems, `uv_os_tmpdir()` uses the first environment
+    variable found in the ordered list `TMPDIR`, `TMP`, `TEMP`, and `TEMPDIR`.
+    If none of these are found, the path `"/tmp"` is used, or, on Android,
+    `"/data/local/tmp"` is used. The temp directory is stored in `buffer`. When
+    `uv_os_tmpdir()` is called, `size` indicates the maximum size of `buffer`.
+    On success `size` is set to the string length of `buffer` (which does not
+    include the terminating null). On `UV_ENOBUFS` failure `size` is set to the
+    required length for `buffer`, including the null byte.

+
+.. c:function:: int uv_os_get_passwd(uv_passwd_t* pwd)
+
+    Gets a subset of the password file entry for the current effective uid (not
+    the real uid). The populated data includes the username, euid, gid, shell,
+    and home directory. On non-Windows systems, all data comes from
+    :man:`getpwuid_r(3)`. On Windows, uid and gid are set to -1 and have no

+
+.. c:function:: uint64_t uv_get_constrained_memory(void)
+
+    Gets the total amount of memory available to the process (in bytes) based on

+    is unknown, `0` is returned. If there is a constraining mechanism, but there
+    is no constraint set, `UINT64_MAX` is returned. Note that it is not unusual
+    for this value to be less than or greater than :c:func:`uv_get_total_memory`.

+    acquired from the system CSPRNG. `flags` is reserved for future extension
+    and must currently be 0.
+
+    Short reads are not possible. When less than `buflen` random bytes are

+
+    Convert UTF-16 (or UCS-2) data in `utf16` to WTF-8 data in `*wtf8_ptr`. The

+===================================
+
+Pipe handles provide an abstraction over streaming files on Unix (including

+
+:c:type:`uv_pipe_t` is a 'subclass' of :c:type:`uv_stream_t`.
+
+
+Data types

+
+
+Public members
+^^^^^^^^^^^^^^

+
+    Initialize a pipe handle. The `ipc` argument is a boolean to indicate if
+    this pipe will be used for handle passing between processes (which may
+    change the bytes on the wire). Only a connected pipe that will be
+    passing the handles should have this flag set, not the listening pipe
+    that uv_accept is called on.

+
+:c:type:`uv_poll_t` --- Poll handle
+===================================
+
+Poll handles are used to watch file descriptors for readability,
+writability and disconnection similar to the purpose of :man:`poll(2)`.
+
+The purpose of poll handles is to enable integrating external libraries that
+rely on the event loop to signal it about the socket status changes, like
+c-ares or libssh2. Using uv_poll_t for any other purpose is not recommended;
+:c:type:`uv_tcp_t`, :c:type:`uv_udp_t`, etc. provide an implementation that is faster and
+more scalable than what can be achieved with :c:type:`uv_poll_t`, especially on
+Windows.
+
+It is possible that poll handles occasionally signal that a file descriptor is
+readable or writable even when it isn't. The user should therefore always
+be prepared to handle EAGAIN or equivalent when it attempts to read from or
+write to the fd.
+
+It is not okay to have multiple active poll handles for the same socket, this
+can cause libuv to busyloop or otherwise malfunction.
+
+The user should not close a file descriptor while it is being polled by an
+active poll handle. This can cause the handle to report an error,
+but it might also start polling another socket. However the fd can be safely
+closed immediately after a call to :c:func:`uv_poll_stop` or :c:func:`uv_close`.
+
+.. note::
+    On windows only sockets can be polled with poll handles. On Unix any file
+    descriptor that would be accepted by :man:`poll(2)` can be used.
+
+.. note::
+    On AIX, watching for disconnection is not supported.

+API
+---
+
+.. c:function:: int uv_poll_init(uv_loop_t* loop, uv_poll_t* handle, int fd)
+
+    Initialize the handle using a file descriptor.
+
+    .. versionchanged:: 1.2.2 the file descriptor is set to non-blocking mode.
+
+.. c:function:: int uv_poll_init_socket(uv_loop_t* loop, uv_poll_t* handle, uv_os_sock_t socket)
+
+    Initialize the handle using a socket descriptor. On Unix this is identical
+    to :c:func:`uv_poll_init`. On windows it takes a SOCKET handle.
+
+    .. versionchanged:: 1.2.2 the socket is set to non-blocking mode.
+
+.. c:function:: int uv_poll_start(uv_poll_t* handle, int events, uv_poll_cb cb)
+
+    Starts polling the file descriptor. `events` is a bitmask made up of
+    `UV_READABLE`, `UV_WRITABLE`, `UV_PRIORITIZED` and `UV_DISCONNECT`. As soon
+    as an event is detected the callback will be called with `status` set to 0,
+    and the detected events set on the `events` field.
+
+    The `UV_PRIORITIZED` event is used to watch for sysfs interrupts or TCP
+    out-of-band messages.
+
+    The `UV_DISCONNECT` event is optional in the sense that it may not be
+    reported and the user is free to ignore it, but it can help optimize the
+    shutdown path because an extra read or write call might be avoided.
+
+    If an error happens while polling, `status` will be < 0 and corresponds
+    with one of the `UV_E*` error codes (see :ref:`errors`). The user should
+    not close the socket while the handle is active. If the user does that
+    anyway, the callback *may* be called reporting an error status, but this is
+    **not** guaranteed. If `status == UV_EBADF` polling is discontinued for the
+    file handle and no further events will be reported. The user should
+    then call :c:func:`uv_close` on the handle.
+
+    .. note::
+        Calling :c:func:`uv_poll_start` on a handle that is already active is
+        fine. Doing so will update the events mask that is being watched for.
+
+    .. note::
+        Though `UV_DISCONNECT` can be set, it is unsupported on AIX and as such
+        will not be set on the `events` field in the callback.
+
+    .. note::
+        If one of the events `UV_READABLE` or `UV_WRITABLE` are set, the
+        callback will be called again, as long as the given fd/socket remains
+        readable or writable accordingly. Particularly in each of the following
+        scenarios:
+
+        * The callback has been called because the socket became
+          readable/writable and the callback did not conduct a read/write on
+          this socket at all.
+        * The callback committed a read on the socket, and has not read all the

+
+:c:type:`uv_signal_t` --- Signal handle
+=======================================
+
+Signal handles implement Unix style signal handling on a per-event loop bases.
+
+Windows notes
+-------------
+
+Reception of some signals is emulated:
+
+* SIGINT is normally delivered when the user presses CTRL+C. However, like
+  on Unix, it is not generated when terminal raw mode is enabled.
+
+* SIGBREAK is delivered when the user pressed CTRL + BREAK.
+
+* SIGHUP is generated when the user closes the console window. On SIGHUP the
+  program is given approximately 10 seconds to perform cleanup. After that
+  Windows will unconditionally terminate it.
+
+* SIGWINCH is raised whenever libuv detects that the console has been
+  resized. When a libuv app is running under a console emulator, or when a
+  32-bit libuv app is running on 64-bit system, SIGWINCH will be emulated. In
+  such cases SIGWINCH signals may not always be delivered in a timely manner.
+  For a writable :c:type:`uv_tty_t` handle libuv will only detect size changes
+  when the cursor is moved. When a readable :c:type:`uv_tty_t` handle is used,
+  resizing of the console buffer will be detected only if the handle is in raw
+  mode and is being read.
+
+* Watchers for other signals can be successfully created, but these signals
+  are never received. These signals are: `SIGILL`, `SIGABRT`, `SIGFPE`, `SIGSEGV`,
+  `SIGTERM` and `SIGKILL.`
+
+* Calls to raise() or abort() to programmatically raise a signal are
+  not detected by libuv; these will not trigger a signal watcher.
+
+.. versionchanged:: 1.15.0 SIGWINCH support on Windows was improved.
+.. versionchanged:: 1.31.0 32-bit libuv SIGWINCH support on 64-bit Windows was
+                           rolled back to old implementation.
+
+Unix notes
+----------
+
+* SIGKILL and SIGSTOP are impossible to catch.
+
+* Handling SIGBUS, SIGFPE, SIGILL or SIGSEGV via libuv results into undefined behavior.
+
+* SIGABRT will not be caught by libuv if generated by `abort()`, e.g. through `assert()`.
+
+* On Linux SIGRT0 and SIGRT1 (signals 32 and 33) are used by the NPTL pthreads library to
+  manage threads. Installing watchers for those signals will lead to unpredictable behavior
+  and is strongly discouraged. Future versions of libuv may simply reject them.
+
+
+Data types
+----------
+
+.. c:type:: uv_signal_t
+
+    Signal handle type.
+
+.. c:type:: void (*uv_signal_cb)(uv_signal_t* handle, int signum)
+
+    Type definition for callback passed to :c:func:`uv_signal_start`.
+
+
+Public members
+^^^^^^^^^^^^^^
+
+.. c:member:: int uv_signal_t.signum
+
+    Signal being monitored by this handle. Readonly.
+
+.. seealso:: The :c:type:`uv_handle_t` members also apply.
+
+
+API
+---
+
+.. c:function:: int uv_signal_init(uv_loop_t* loop, uv_signal_t* signal)
+
+    Initialize the handle.
+
+.. c:function:: int uv_signal_start(uv_signal_t* signal, uv_signal_cb cb, int signum)
+
+    Start the handle with the given callback, watching for the given signal.
+
+.. c:function:: int uv_signal_start_oneshot(uv_signal_t* signal, uv_signal_cb cb, int signum)
+
+    .. versionadded:: 1.12.0
+
+    Same functionality as :c:func:`uv_signal_start` but the signal handler is reset the moment
+    the signal is received.
+
+.. c:function:: int uv_signal_stop(uv_signal_t* signal)
+
+    Stop the handle, the callback will no longer be called.
+
+.. seealso:: The :c:type:`uv_handle_t` API functions also apply.

+
+:c:type:`uv_stream_t` --- Stream handle
+=======================================
+
+Stream handles provide an abstraction of a duplex communication channel.
+:c:type:`uv_stream_t` is an abstract type, libuv provides 3 stream implementations
+in the form of :c:type:`uv_tcp_t`, :c:type:`uv_pipe_t` and :c:type:`uv_tty_t`.
+
+
+Data types
+----------
+
+.. c:type:: uv_stream_t
+
+    Stream handle type.
+
+.. c:type:: uv_connect_t
+
+    Connect request type.
+
+.. c:type:: uv_shutdown_t
+
+    Shutdown request type.
+
+.. c:type:: uv_write_t
+
+    Write request type. Careful attention must be paid when reusing objects of
+    this type. When a stream is in non-blocking mode, write requests sent
+    with ``uv_write`` will be queued. Reusing objects at this point is undefined
+    behaviour. It is safe to reuse the ``uv_write_t`` object only after the
+    callback passed to ``uv_write`` is fired.
+
+.. c:type:: void (*uv_read_cb)(uv_stream_t* stream, ssize_t nread, const uv_buf_t* buf)
+
+    Callback called when data was read on a stream.
+
+    `nread` is > 0 if there is data available or < 0 on error. When we've
+    reached EOF, `nread` will be set to ``UV_EOF``. When `nread` < 0,
+    the `buf` parameter might not point to a valid buffer; in that case
+    `buf.len` and `buf.base` are both set to 0.
+
+    .. note::
+        `nread` might be 0, which does *not* indicate an error or EOF. This
+        is equivalent to ``EAGAIN`` or ``EWOULDBLOCK`` under ``read(2)``.
+
+    The callee is responsible for stopping/closing the stream when an error happens
+    by calling :c:func:`uv_read_stop` or :c:func:`uv_close`. Trying to read
+    from the stream again is undefined.
+
+    The callee is responsible for freeing the buffer, libuv does not reuse it.
+    The buffer may be a null buffer (where `buf->base` == NULL and `buf->len` == 0)
+    on error.
+
+.. c:type:: void (*uv_write_cb)(uv_write_t* req, int status)
+
+    Callback called after data was written on a stream. `status` will be 0 in
+    case of success, < 0 otherwise.
+
+.. c:type:: void (*uv_connect_cb)(uv_connect_t* req, int status)
+
+    Callback called after a connection started by :c:func:`uv_connect` is done.
+    `status` will be 0 in case of success, < 0 otherwise.
+
+.. c:type:: void (*uv_shutdown_cb)(uv_shutdown_t* req, int status)
+
+    Callback called after a shutdown request has been completed. `status` will
+    be 0 in case of success, < 0 otherwise.
+
+.. c:type:: void (*uv_connection_cb)(uv_stream_t* server, int status)
+
+    Callback called when a stream server has received an incoming connection.
+    The user can accept the connection by calling :c:func:`uv_accept`.
+    `status` will be 0 in case of success, < 0 otherwise.
+
+
+Public members
+^^^^^^^^^^^^^^
+
+.. c:member:: size_t uv_stream_t.write_queue_size
+
+    Contains the amount of queued bytes waiting to be sent. Readonly.
+
+.. c:member:: uv_stream_t* uv_connect_t.handle
+
+    Pointer to the stream where this connection request is running.
+
+.. c:member:: uv_stream_t* uv_shutdown_t.handle
+
+    Pointer to the stream where this shutdown request is running.
+
+.. c:member:: uv_stream_t* uv_write_t.handle
+
+    Pointer to the stream where this write request is running.
+
+.. c:member:: uv_stream_t* uv_write_t.send_handle
+
+    Pointer to the stream being sent using this write request.
+
+.. seealso:: The :c:type:`uv_handle_t` members also apply.
+
+
+API
+---
+
+.. c:function:: int uv_shutdown(uv_shutdown_t* req, uv_stream_t* handle, uv_shutdown_cb cb)
+
+    Shutdown the outgoing (write) side of a duplex stream. It waits for pending
+    write requests to complete. The `handle` should refer to a initialized stream.
+    `req` should be an uninitialized shutdown request struct. The `cb` is called
+    after shutdown is complete.
+
+.. c:function:: int uv_listen(uv_stream_t* stream, int backlog, uv_connection_cb cb)
+
+    Start listening for incoming connections. `backlog` indicates the number of
+    connections the kernel might queue, same as :man:`listen(2)`. When a new
+    incoming connection is received the :c:type:`uv_connection_cb` callback is
+    called.
+
+.. c:function:: int uv_accept(uv_stream_t* server, uv_stream_t* client)
+
+    This call is used in conjunction with :c:func:`uv_listen` to accept incoming
+    connections. Call this function after receiving a :c:type:`uv_connection_cb`
+    to accept the connection. Before calling this function the client handle must
+    be initialized. < 0 return value indicates an error.
+
+    When the :c:type:`uv_connection_cb` callback is called it is guaranteed that
+    this function will complete successfully the first time. If you attempt to use
+    it more than once, it may fail. It is suggested to only call this function once
+    per :c:type:`uv_connection_cb` call.
+
+    .. note::
+        `server` and `client` must be handles running on the same loop.
+
+.. c:function:: int uv_read_start(uv_stream_t* stream, uv_alloc_cb alloc_cb, uv_read_cb read_cb)
+
+    Read data from an incoming stream. The :c:type:`uv_read_cb` callback will
+    be made several times until there is no more data to read or
+    :c:func:`uv_read_stop` is called.
+
+    .. versionchanged:: 1.38.0 :c:func:`uv_read_start()` now consistently
+      returns `UV_EALREADY` when called twice, and `UV_EINVAL` when the
+      stream is closing. With older libuv versions, it returns `UV_EALREADY`
+      on Windows but not UNIX, and `UV_EINVAL` on UNIX but not Windows.
+
+.. c:function:: int uv_read_stop(uv_stream_t*)
+
+    Stop reading data from the stream. The :c:type:`uv_read_cb` callback will
+    no longer be called.
+
+    This function is idempotent and may be safely called on a stopped stream.
+
+    This function will always succeed; hence, checking its return value is
+    unnecessary. A non-zero return indicates that finishing releasing resources
+    may be pending on the next input event on that TTY on Windows, and does not
+    indicate failure.
+
+.. c:function:: int uv_write(uv_write_t* req, uv_stream_t* handle, const uv_buf_t bufs[], unsigned int nbufs, uv_write_cb cb)
+
+    Write data to stream. Buffers are written in order. Example:
+
+    ::
+
+        void cb(uv_write_t* req, int status) {
+            /* Logic which handles the write result */
+        }
+
+        uv_buf_t a[] = {
+            { .base = "1", .len = 1 },
+            { .base = "2", .len = 1 }
+        };
+
+        uv_buf_t b[] = {
+            { .base = "3", .len = 1 },
+            { .base = "4", .len = 1 }
+        };
+
+        uv_write_t req1;
+        uv_write_t req2;
+
+        /* writes "1234" */
+        uv_write(&req1, stream, a, 2, cb);
+        uv_write(&req2, stream, b, 2, cb);
+
+    .. note::
+        The memory pointed to by the buffers must remain valid until the callback gets called.
+        This also holds for :c:func:`uv_write2`.
+
+.. c:function:: int uv_write2(uv_write_t* req, uv_stream_t* handle, const uv_buf_t bufs[], unsigned int nbufs, uv_stream_t* send_handle, uv_write_cb cb)
+
+    Extended write function for sending handles over a pipe. The pipe must be
+    initialized with `ipc` == 1.
+
+    .. note::
+        `send_handle` must be a TCP, pipe and UDP handle on Unix, or a TCP
+        handle on Windows, which is a server or a connection (listening or
+        connected state). Bound sockets or pipes will be assumed to be servers.
+
+.. c:function:: int uv_try_write(uv_stream_t* handle, const uv_buf_t bufs[], unsigned int nbufs)
+
+    Same as :c:func:`uv_write`, but won't queue a write request if it can't be
+    completed immediately.
+
+    Will return either:
+
+    * > 0: number of bytes written (can be less than the supplied buffer size).
+    * < 0: negative error code (``UV_EAGAIN`` is returned if no data can be sent
+      immediately).
+
+.. c:function:: int uv_try_write2(uv_stream_t* handle, const uv_buf_t bufs[], unsigned int nbufs, uv_stream_t* send_handle)
+
+    Same as :c:func:`uv_try_write` and extended write function for sending
+    handles over a pipe like c:func:`uv_write2`.
+
+    Try to send a handle is not supported on Windows,
+    where it returns ``UV_EAGAIN``.
+
+    .. versionadded:: 1.42.0
+    
+.. c:function:: int uv_is_readable(const uv_stream_t* handle)
+
+    Returns 1 if the stream is readable, 0 otherwise.
+
+.. c:function:: int uv_is_writable(const uv_stream_t* handle)
+
+    Returns 1 if the stream is writable, 0 otherwise.
+
+.. c:function:: int uv_stream_set_blocking(uv_stream_t* handle, int blocking)
+
+    Enable or disable blocking mode for a stream.
+
+    When blocking mode is enabled all writes complete synchronously. The
+    interface remains unchanged otherwise, e.g. completion or failure of the
+    operation will still be reported through a callback which is made
+    asynchronously.
+
+    .. warning::
+        Relying too much on this API is not recommended. It is likely to change
+        significantly in the future.
+
+        Currently only works on Windows for :c:type:`uv_pipe_t` handles.
+        On UNIX platforms, all :c:type:`uv_stream_t` handles are supported.
+
+        Also libuv currently makes no ordering guarantee when the blocking mode
+        is changed after write requests have already been submitted. Therefore it is
+        recommended to set the blocking mode immediately after opening or creating
+        the stream.
+
+    .. versionchanged:: 1.4.0 UNIX implementation added.
+
+.. c:function:: size_t uv_stream_get_write_queue_size(const uv_stream_t* stream)
+
+    Returns `stream->write_queue_size`.
+
+    .. versionadded:: 1.19.0
+
+.. seealso:: The :c:type:`uv_handle_t` API functions also apply.

+
+:c:type:`uv_tcp_t` --- TCP handle
+=================================
+
+TCP handles are used to represent both TCP streams and servers.
+
+:c:type:`uv_tcp_t` is a 'subclass' of :c:type:`uv_stream_t`.
+
+
+Data types
+----------
+
+.. c:type:: uv_tcp_t
+
+    TCP handle type.
+
+
+Public members
+^^^^^^^^^^^^^^
+
+N/A
+
+.. seealso:: The :c:type:`uv_stream_t` members also apply.
+
+
+API
+---
+
+.. c:function:: int uv_tcp_init(uv_loop_t* loop, uv_tcp_t* handle)
+
+    Initialize the handle. No socket is created as of yet.
+
+.. c:function:: int uv_tcp_init_ex(uv_loop_t* loop, uv_tcp_t* handle, unsigned int flags)
+
+    Initialize the handle with the specified flags. At the moment only the lower 8 bits
+    of the `flags` parameter are used as the socket domain. A socket will be created
+    for the given domain. If the specified domain is ``AF_UNSPEC`` no socket is created,
+    just like :c:func:`uv_tcp_init`.
+
+    .. versionadded:: 1.7.0
+
+.. c:function:: int uv_tcp_open(uv_tcp_t* handle, uv_os_sock_t sock)
+
+    Open an existing file descriptor or SOCKET as a TCP handle.
+
+    .. versionchanged:: 1.2.1 the file descriptor is set to non-blocking mode.
+
+    .. note::
+        The passed file descriptor or SOCKET is not checked for its type, but
+        it's required that it represents a valid stream socket.
+
+.. c:function:: int uv_tcp_nodelay(uv_tcp_t* handle, int enable)
+
+    Enable `TCP_NODELAY`, which disables Nagle's algorithm.
+
+.. c:function:: int uv_tcp_keepalive(uv_tcp_t* handle, int enable, unsigned int delay)
+
+    Enable / disable TCP keep-alive. `delay` is the initial delay in seconds,
+    ignored when `enable` is zero.
+
+    After `delay` has been reached, 10 successive probes, each spaced 1 second
+    from the previous one, will still happen. If the connection is still lost
+    at the end of this procedure, then the handle is destroyed with a
+    ``UV_ETIMEDOUT`` error passed to the corresponding callback.
+
+.. c:function:: int uv_tcp_simultaneous_accepts(uv_tcp_t* handle, int enable)
+
+    Enable / disable simultaneous asynchronous accept requests that are
+    queued by the operating system when listening for new TCP connections.
+
+    This setting is used to tune a TCP server for the desired performance.
+    Having simultaneous accepts can significantly improve the rate of accepting
+    connections (which is why it is enabled by default) but may lead to uneven
+    load distribution in multi-process setups.
+
+.. c:function:: int uv_tcp_bind(uv_tcp_t* handle, const struct sockaddr* addr, unsigned int flags)
+
+    Bind the handle to an address and port. `addr` should point to an
+    initialized ``struct sockaddr_in`` or ``struct sockaddr_in6``.
+
+    When the port is already taken, you can expect to see an ``UV_EADDRINUSE``
+    error from :c:func:`uv_listen` or :c:func:`uv_tcp_connect`. That is,
+    a successful call to this function does not guarantee that the call
+    to :c:func:`uv_listen` or :c:func:`uv_tcp_connect` will succeed as well.
+
+    `flags` can contain ``UV_TCP_IPV6ONLY``, in which case dual-stack support
+    is disabled and only IPv6 is used.
+
+.. c:function:: int uv_tcp_getsockname(const uv_tcp_t* handle, struct sockaddr* name, int* namelen)
+
+    Get the current address to which the handle is bound. `name` must point to
+    a valid and big enough chunk of memory, ``struct sockaddr_storage`` is
+    recommended for IPv4 and IPv6 support.
+
+.. c:function:: int uv_tcp_getpeername(const uv_tcp_t* handle, struct sockaddr* name, int* namelen)
+
+    Get the address of the peer connected to the handle. `name` must point to
+    a valid and big enough chunk of memory, ``struct sockaddr_storage`` is
+    recommended for IPv4 and IPv6 support.
+
+.. c:function:: int uv_tcp_connect(uv_connect_t* req, uv_tcp_t* handle, const struct sockaddr* addr, uv_connect_cb cb)
+
+    Establish an IPv4 or IPv6 TCP connection. Provide an initialized TCP handle
+    and an uninitialized :c:type:`uv_connect_t`. `addr` should point to an
+    initialized ``struct sockaddr_in`` or ``struct sockaddr_in6``.
+
+    On Windows if the `addr` is initialized to point to an unspecified address
+    (``0.0.0.0`` or ``::``) it will be changed to point to ``localhost``.
+    This is done to match the behavior of Linux systems.
+
+    The callback is made when the connection has been established or when a
+    connection error happened.
+
+    .. versionchanged:: 1.19.0 added ``0.0.0.0`` and ``::`` to ``localhost``
+        mapping

+
+.. c:function:: int uv_tcp_close_reset(uv_tcp_t* handle, uv_close_cb close_cb)
+
+    Resets a TCP connection by sending a RST packet. This is accomplished by
+    setting the `SO_LINGER` socket option with a linger interval of zero and
+    then calling :c:func:`uv_close`.
+    Due to some platform inconsistencies, mixing of :c:func:`uv_shutdown` and
+    :c:func:`uv_tcp_close_reset` calls is not allowed.
+
+    .. versionadded:: 1.32.0
+
+.. c:function:: int uv_socketpair(int type, int protocol, uv_os_sock_t socket_vector[2], int flags0, int flags1)
+
+    Create a pair of connected sockets with the specified properties.
+    The resulting handles can be passed to `uv_tcp_open`, used with `uv_spawn`,
+    or for any other purpose.
+
+    Valid values for `flags0` and `flags1` are:
+
+      - UV_NONBLOCK_PIPE: Opens the specified socket handle for `OVERLAPPED`
+        or `FIONBIO`/`O_NONBLOCK` I/O usage.
+        This is recommended for handles that will be used by libuv,
+        and not usually recommended otherwise.
+
+    Equivalent to :man:`socketpair(2)` with a domain of AF_UNIX.

+
+.. c:function:: int uv_thread_create_ex(uv_thread_t* tid, const uv_thread_options_t* params, uv_thread_cb entry, void* arg)
+
+    Like :c:func:`uv_thread_create`, but additionally specifies options for creating a new thread.
+
+    If `UV_THREAD_HAS_STACK_SIZE` is set, `stack_size` specifies a stack size for the new thread.
+    `0` indicates that the default value should be used, i.e. behaves as if the flag was not set.
+    Other values will be rounded up to the nearest page boundary.

+    .. versionadded:: 1.26.0
+
+.. c:function:: int uv_thread_setaffinity(uv_thread_t* tid, char* cpumask, char* oldmask, size_t mask_size)
+
+    Sets the specified thread's affinity to cpumask, which is specified in
+    bytes. Optionally returning the previous affinity setting in oldmask.
+    On Unix, uses :man:`pthread_getaffinity_np(3)` to get the affinity setting
+    and maps the cpu_set_t to bytes in oldmask. Then maps the bytes in cpumask
+    to a cpu_set_t and uses :man:`pthread_setaffinity_np(3)`. On Windows, maps
+    the bytes in cpumask to a bitmask and uses SetThreadAffinityMask() which
+    returns the previous affinity setting.

+
+    The mask_size specifies the number of entries (bytes) in cpumask,

+        Thread affinity getting is not atomic on Windows. Unsupported on macOS.
+
+    .. versionadded:: 1.45.0
+
+.. c:function:: int uv_thread_getcpu(void)
+
+    Gets the CPU number on which the calling thread is running.
+
+    .. note::
+        Currently only implemented on Windows, Linux and FreeBSD.

+.. c:function:: int uv_thread_setpriority(uv_thread_t tid, int priority)
+    If the function succeeds, the return value is 0.
+    If the function fails, the return value is less than zero.
+    Sets the scheduling priority of the thread specified by tid. It requires elevated
+    privilege to set specific priorities on some platforms.
+    The priority can be set to the following constants. UV_THREAD_PRIORITY_HIGHEST, 
+    UV_THREAD_PRIORITY_ABOVE_NORMAL, UV_THREAD_PRIORITY_NORMAL, 
+    UV_THREAD_PRIORITY_BELOW_NORMAL, UV_THREAD_PRIORITY_LOWEST.
+.. c:function:: int uv_thread_getpriority(uv_thread_t tid, int* priority)
+    If the function succeeds, the return value is 0.
+    If the function fails, the return value is less than zero.
+    Retrieves the scheduling priority of the thread specified by tid. The value in the
+    output parameter priority is platform dependent.
+    For Linux, when schedule policy is SCHED_OTHER (default), priority is 0.
+
+Thread-local storage
+^^^^^^^^^^^^^^^^^^^^
+
+.. note::
+    The total thread-local storage size may be limited. That is, it may not be possible to
+    create many TLS keys.

+
+Once-only initialization
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+Runs a function once and only once. Concurrent calls to :c:func:`uv_once` with the
+same guard will block all callers except one (it's unspecified which one).
+The guard should be initialized statically with the UV_ONCE_INIT macro.

+
+.. note::
+    1. Callers should be prepared to deal with spurious wakeups on :c:func:`uv_cond_wait`
+       and :c:func:`uv_cond_timedwait`.
+    2. The timeout parameter for :c:func:`uv_cond_timedwait` is relative to the time
+       at which function is called.
+    3. On z/OS, the timeout parameter for :c:func:`uv_cond_timedwait` is converted to an
+       absolute system time at which the wait expires. If the current system clock time
+       passes the absolute time calculated before the condition is signaled, an ETIMEDOUT
+       error results. After the wait begins, the wait time is not affected by changes
+       to the system clock.
+
+.. c:function:: int uv_cond_init(uv_cond_t* cond)
+.. c:function:: void uv_cond_destroy(uv_cond_t* cond)

+
+Barriers
+^^^^^^^^
+
+Functions return 0 on success or an error code < 0 (unless the
+return type is void, of course).
+
+.. note::
+    :c:func:`uv_barrier_wait` returns a value > 0 to an arbitrarily chosen "serializer" thread
+    to facilitate cleanup, i.e.
+
+    ::

+
+Thread pool work scheduling
+===========================
+
+libuv provides a threadpool which can be used to run user code and get notified
+in the loop thread. This thread pool is internally used to run all file system
+operations, as well as getaddrinfo and getnameinfo requests.
+
+Its default size is 4, but it can be changed at startup time by setting the
+``UV_THREADPOOL_SIZE`` environment variable to any value (the absolute maximum
+is 1024).
+
+.. versionchanged:: 1.30.0 the maximum UV_THREADPOOL_SIZE allowed was increased from 128 to 1024.
+
+.. versionchanged:: 1.45.0 threads now have an 8 MB stack instead of the
+   (sometimes too low) platform default.
+
+The threadpool is global and shared across all event loops. When a particular
+function makes use of the threadpool (i.e. when using :c:func:`uv_queue_work`)
+libuv preallocates and initializes the maximum number of threads allowed by
+``UV_THREADPOOL_SIZE``. This causes a relatively minor memory overhead
+(~1MB for 128 threads) but increases the performance of threading at runtime.
+
+.. note::
+    Note that even though a global thread pool which is shared across all events
+    loops is used, the functions are not thread safe.
+
+
+Data types
+----------
+
+.. c:type:: uv_work_t
+
+    Work request type.
+
+.. c:type:: void (*uv_work_cb)(uv_work_t* req)

+    pool.
+
+.. c:type:: void (*uv_after_work_cb)(uv_work_t* req, int status)
+
+    Callback passed to :c:func:`uv_queue_work` which will be called on the loop
+    thread after the work on the threadpool has been completed. If the work
+    was cancelled using :c:func:`uv_cancel` `status` will be ``UV_ECANCELED``.

+    This function is not thread safe on systems that don't support
+    ioctl TIOCGPTN or TIOCPTYGNAME, for instance OpenBSD and Solaris.
+
+    .. note::
+        If reopening the TTY fails, libuv falls back to blocking writes.
+
+    .. versionchanged:: 1.23.1: the `readable` parameter is now unused and ignored.
+                        The correct value will now be auto-detected from the kernel.
+
+    .. versionchanged:: 1.9.0: the path of the TTY is determined by
+                        :man:`ttyname_r(3)`. In earlier versions libuv opened
+                        `/dev/tty` instead.
+
+    .. versionchanged:: 1.5.0: trying to initialize a TTY stream with a file

+
+.. c:type:: void (*uv_udp_recv_cb)(uv_udp_t* handle, ssize_t nread, const uv_buf_t* buf, const struct sockaddr* addr, unsigned flags)
+
+    Type definition for callback passed to :c:func:`uv_udp_recv_start`, which
+    is called when the endpoint receives data.
+
+    * `handle`: UDP handle
+    * `nread`:  Number of bytes that have been received.
+      0 if there is no more data to read. Note that 0 may also mean that an
+      empty datagram was received (in this case `addr` is not NULL). < 0 if
+      a transmission error was detected; if using :man:`recvmmsg(2)` no more
+      chunks will be received and the buffer can be freed safely.
+    * `buf`: :c:type:`uv_buf_t` with the received data.
+    * `addr`: ``struct sockaddr*`` containing the address of the sender.
+      Can be NULL. Valid for the duration of the callback only.
+    * `flags`: One or more or'ed UV_UDP_* constants.
+
+    The callee is responsible for freeing the buffer, libuv does not reuse it.
+    The buffer may be a null buffer (where `buf->base` == NULL and `buf->len` == 0)
+    on error.
+
+    When using :man:`recvmmsg(2)`, chunks will have the `UV_UDP_MMSG_CHUNK` flag set,
+    those must not be freed. If no errors occur, there will be a final callback with
+    `nread` set to 0, `addr` set to NULL and the buffer pointing at the initially
+    allocated data with the `UV_UDP_MMSG_CHUNK` flag cleared and the `UV_UDP_MMSG_FREE`
+    flag set. If a UDP socket error occurs, `nread` will be < 0. In either scenario,
+    the callee can now safely free the provided buffer.
+
+    .. versionchanged:: 1.40.0 added the `UV_UDP_MMSG_FREE` flag.
+
+    .. note::
+        The receive callback will be called with `nread` == 0 and `addr` == NULL when there is
+        nothing to read, and with `nread` == 0 and `addr` != NULL when an empty UDP packet is
+        received.

+Public members
+^^^^^^^^^^^^^^
+
+.. c:member:: size_t uv_udp_t.send_queue_size
+
+    Number of bytes queued for sending. This field strictly shows how much
+    information is currently queued.
+
+.. c:member:: size_t uv_udp_t.send_queue_count
+
+    Number of send requests currently in the queue awaiting to be processed.
+
+.. c:member:: uv_udp_t* uv_udp_send_t.handle
+
+    UDP handle where this send request is taking place.
+
+.. seealso:: The :c:type:`uv_handle_t` members also apply.
+
+
+API
+---
+
+.. c:function:: int uv_udp_init(uv_loop_t* loop, uv_udp_t* handle)
+
+    Initialize a new UDP handle. The actual socket is created lazily.
+    Returns 0 on success.
+
+.. c:function:: int uv_udp_init_ex(uv_loop_t* loop, uv_udp_t* handle, unsigned int flags)
+
+    Initialize the handle with the specified flags. The lower 8 bits of the `flags`
+    parameter are used as the socket domain. A socket will be created for the given domain.
+    If the specified domain is ``AF_UNSPEC`` no socket is created, just like :c:func:`uv_udp_init`.
+
+    The remaining bits can be used to set one of these flags:
+
+    * `UV_UDP_RECVMMSG`: if set, and the platform supports it, :man:`recvmmsg(2)` will
+      be used.
+
+    .. versionadded:: 1.7.0
+    .. versionchanged:: 1.37.0 added the `UV_UDP_RECVMMSG` flag.
+
+.. c:function:: int uv_udp_open(uv_udp_t* handle, uv_os_sock_t sock)
+
+    Opens an existing file descriptor or Windows SOCKET as a UDP handle.
+
+    Unix only:
+    The only requirement of the `sock` argument is that it follows the datagram
+    contract (works in unconnected mode, supports sendmsg()/recvmsg(), etc).
+    In other words, other datagram-type sockets like raw sockets or netlink
+    sockets can also be passed to this function.
+
+    .. versionchanged:: 1.2.1 the file descriptor is set to non-blocking mode.
+
+    .. note::
+        The passed file descriptor or SOCKET is not checked for its type, but
+        it's required that it represents a valid datagram socket.
+
+.. c:function:: int uv_udp_bind(uv_udp_t* handle, const struct sockaddr* addr, unsigned int flags)
+
+    Bind the UDP handle to an IP address and port.
+
+    :param handle: UDP handle. Should have been initialized with
+        :c:func:`uv_udp_init`.
+
+    :param addr: `struct sockaddr_in` or `struct sockaddr_in6`
+        with the address and port to bind to.
+
+    :param flags: Indicate how the socket will be bound,
+        ``UV_UDP_IPV6ONLY``, ``UV_UDP_REUSEADDR``, and ``UV_UDP_RECVERR``
+        are supported.
+
+    :returns: 0 on success, or an error code < 0 on failure.
+
+.. c:function:: int uv_udp_connect(uv_udp_t* handle, const struct sockaddr* addr)
+
+    Associate the UDP handle to a remote address and port, so every
+    message sent by this handle is automatically sent to that destination.
+    Calling this function with a `NULL` `addr` disconnects the handle.
+    Trying to call `uv_udp_connect()` on an already connected handle will result
+    in an `UV_EISCONN` error. Trying to disconnect a handle that is not
+    connected will return an `UV_ENOTCONN` error.
+
+    :param handle: UDP handle. Should have been initialized with
+        :c:func:`uv_udp_init`.
+
+    :param addr: `struct sockaddr_in` or `struct sockaddr_in6`
+        with the address and port to associate to.
+
+    :returns: 0 on success, or an error code < 0 on failure.
+
+    .. versionadded:: 1.27.0
+
+.. c:function:: int uv_udp_getpeername(const uv_udp_t* handle, struct sockaddr* name, int* namelen)
+
+    Get the remote IP and port of the UDP handle on connected UDP handles.
+    On unconnected handles, it returns `UV_ENOTCONN`.
+
+    :param handle: UDP handle. Should have been initialized with
+        :c:func:`uv_udp_init` and bound.
+
+    :param name: Pointer to the structure to be filled with the address data.
+        In order to support IPv4 and IPv6 `struct sockaddr_storage` should be
+        used.
+
+    :param namelen: On input it indicates the data of the `name` field. On
+        output it indicates how much of it was filled.
+
+    :returns: 0 on success, or an error code < 0 on failure
+
+    .. versionadded:: 1.27.0
+
+.. c:function:: int uv_udp_getsockname(const uv_udp_t* handle, struct sockaddr* name, int* namelen)
+
+    Get the local IP and port of the UDP handle.
+

+        :c:func:`uv_udp_init` and bound.
+
+    :param name: Pointer to the structure to be filled with the address data.

+
+    :param interface_addr: Interface address.
+
+    :param membership: Should be ``UV_JOIN_GROUP`` or ``UV_LEAVE_GROUP``.
+
+    :returns: 0 on success, or an error code < 0 on failure.
+
+.. c:function:: int uv_udp_set_source_membership(uv_udp_t* handle, const char* multicast_addr, const char* interface_addr, const char* source_addr, uv_membership membership)
+
+    Set membership for a source-specific multicast group.
+

+    .. versionadded:: 1.32.0
+
+.. c:function:: int uv_udp_set_multicast_loop(uv_udp_t* handle, int on)
+
+    Set IP multicast loop flag. Makes multicast packets loop back to
+    local sockets.
+

+
+    Set the multicast interface to send or receive data on.

+.. c:function:: int uv_udp_send(uv_udp_send_t* req, uv_udp_t* handle, const uv_buf_t bufs[], unsigned int nbufs, const struct sockaddr* addr, uv_udp_send_cb send_cb)
+
+    Send data over the UDP socket. If the socket has not previously been bound
+    with :c:func:`uv_udp_bind` it will be bound to 0.0.0.0
+    (the "all interfaces" IPv4 address) and a random port number.
+
+    On Windows if the `addr` is initialized to point to an unspecified address
+    (``0.0.0.0`` or ``::``) it will be changed to point to ``localhost``.
+    This is done to match the behavior of Linux systems.
+
+    For connected UDP handles, `addr` must be set to `NULL`, otherwise it will
+    return `UV_EISCONN` error.
+
+    For connectionless UDP handles, `addr` cannot be `NULL`, otherwise it will
+    return `UV_EDESTADDRREQ` error.
+
+    :param req: UDP request handle. Need not be initialized.
+
+    :param handle: UDP handle. Should have been initialized with
+        :c:func:`uv_udp_init`.
+
+    :param bufs: List of buffers to send.
+
+    :param nbufs: Number of buffers in `bufs`.
+
+    :param addr: `struct sockaddr_in` or `struct sockaddr_in6` with the
+        address and port of the remote peer.
+
+    :param send_cb: Callback to invoke when the data has been sent out.
+
+    :returns: 0 on success, or an error code < 0 on failure.
+
+    .. versionchanged:: 1.19.0 added ``0.0.0.0`` and ``::`` to ``localhost``
+        mapping
+
+    .. versionchanged:: 1.27.0 added support for connected sockets
+
+.. c:function:: int uv_udp_try_send(uv_udp_t* handle, const uv_buf_t bufs[], unsigned int nbufs, const struct sockaddr* addr)
+
+    Same as :c:func:`uv_udp_send`, but won't queue a send request if it can't
+    be completed immediately.
+
+    For connected UDP handles, `addr` must be set to `NULL`, otherwise it will
+    return `UV_EISCONN` error.
+
+    For connectionless UDP handles, `addr` cannot be `NULL`, otherwise it will
+    return `UV_EDESTADDRREQ` error.
+
+    :returns: >= 0: number of bytes sent (it matches the given buffer size).
+        < 0: negative error code (``UV_EAGAIN`` is returned when the message
+        can't be sent immediately).
+
+    .. versionchanged:: 1.27.0 added support for connected sockets
+
+.. c:function:: int uv_udp_recv_start(uv_udp_t* handle, uv_alloc_cb alloc_cb, uv_udp_recv_cb recv_cb)
+
+    Prepare for receiving data. If the socket has not previously been bound
+    with :c:func:`uv_udp_bind` it is bound to 0.0.0.0 (the "all interfaces"
+    IPv4 address) and a random port number.
+
+    :param handle: UDP handle. Should have been initialized with
+        :c:func:`uv_udp_init`.
+
+    :param alloc_cb: Callback to invoke when temporary storage is needed.
+
+    :param recv_cb: Callback to invoke with received data.
+
+    :returns: 0 on success, or an error code < 0 on failure.
+
+    .. note::
+        When using :man:`recvmmsg(2)`, the number of messages received at a time is limited
+        by the number of max size dgrams that will fit into the buffer allocated in `alloc_cb`, and
+        `suggested_size` in `alloc_cb` for udp_recv is always set to the size of 1 max size dgram.
+
+    .. versionchanged:: 1.35.0 added support for :man:`recvmmsg(2)` on supported platforms).
+                        The use of this feature requires a buffer larger than
+                        2 * 64KB to be passed to `alloc_cb`.
+    .. versionchanged:: 1.37.0 :man:`recvmmsg(2)` support is no longer enabled implicitly,
+                        it must be explicitly requested by passing the `UV_UDP_RECVMMSG` flag to
+                        :c:func:`uv_udp_init_ex`.
+    .. versionchanged:: 1.39.0 :c:func:`uv_udp_using_recvmmsg` can be used in `alloc_cb` to
+                        determine if a buffer sized for use with :man:`recvmmsg(2)` should be
+                        allocated for the current handle/platform.
+
+.. c:function:: int uv_udp_using_recvmmsg(uv_udp_t* handle)
+
+    Returns 1 if the UDP handle was created with the `UV_UDP_RECVMMSG` flag
+    and the platform supports :man:`recvmmsg(2)`, 0 otherwise.
+
+    .. versionadded:: 1.39.0
+
+.. c:function:: int uv_udp_recv_stop(uv_udp_t* handle)
+
+    Stop listening for incoming datagrams.
+
+    :param handle: UDP handle. Should have been initialized with
+        :c:func:`uv_udp_init`.
+
+    :returns: 0 on success, or an error code < 0 on failure.
+
+.. c:function:: size_t uv_udp_get_send_queue_size(const uv_udp_t* handle)
+
+    Returns `handle->send_queue_size`.

+
+.. c:function:: size_t uv_udp_get_send_queue_count(const uv_udp_t* handle)

+Version-checking macros and functions
+=====================================
+
+Starting with version 1.0.0 libuv follows the `semantic versioning`_
+scheme. This means that new APIs can be introduced throughout the lifetime of
+a major release. In this section you'll find all macros and functions that
+will allow you to write or compile code conditionally, in order to work with
+multiple libuv versions.
+
+.. _semantic versioning: https://semver.org
+
+
+Macros
+------
+
+.. c:macro:: UV_VERSION_MAJOR
+
+    libuv version's major number.
+
+.. c:macro:: UV_VERSION_MINOR
+
+    libuv version's minor number.
+
+.. c:macro:: UV_VERSION_PATCH
+
+    libuv version's patch number.
+
+.. c:macro:: UV_VERSION_IS_RELEASE
+
+    Set to 1 to indicate a release version of libuv, 0 for a development
+    snapshot.
+
+.. c:macro:: UV_VERSION_SUFFIX
+
+    libuv version suffix. Certain development releases such as Release Candidates
+    might have a suffix such as "rc".
+
+.. c:macro:: UV_VERSION_HEX
+
+    Returns the libuv version packed into a single integer. 8 bits are used for
+    each component, with the patch number stored in the 8 least significant
+    bits. E.g. for libuv 1.2.3 this would be 0x010203.
+
+    .. versionadded:: 1.7.0
+
+
+Functions
+---------
+
+.. c:function:: unsigned int uv_version(void)
+
+    Returns :c:macro:`UV_VERSION_HEX`.
+
+.. c:function:: const char* uv_version_string(void)
+
+    Returns the libuv version number as a string. For non-release versions the
+    version suffix is included.

+ * This file defines data structures for different types of trees:
+ * splay trees and red-black trees.
+ *
+ * A splay tree is a self-organizing data structure.  Every operation
+ * on the tree causes a splay to happen.  The splay moves the requested
+ * node to the root of the tree and partly rebalances it.
+ *
+ * This has the benefit that request locality causes faster lookups as
+ * the requested nodes move to the top of the tree.  On the other hand,
+ * every lookup causes memory writes.
+ *
+ * The Balance Theorem bounds the total access time for m operations
+ * and n inserts on an initially empty tree as O((m + n)lg n).  The
+ * amortized cost for a sequence of m accesses to a splay tree is O(lg n);
+ *
+ * A red-black tree is a binary search tree with the node color as an
+ * extra attribute.  It fulfills a set of conditions:
+ *  - every search path from the root to a leaf consists of the
+ *    same number of black nodes,
+ *  - each red node (except for the root) has a black parent,
+ *  - each leaf node is black.
+ *
+ * Every operation on a red-black tree is bounded as O(lg n).
+ * The maximum height of a red-black tree is 2lg (n+1).

+# SYNOPSIS
+#
+#   AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
+#
+# DESCRIPTION
+#
+#   This macro figures out how to build C programs using POSIX threads. It
+#   sets the PTHREAD_LIBS output variable to the threads library and linker
+#   flags, and the PTHREAD_CFLAGS output variable to any special C compiler
+#   flags that are needed. (The user can also force certain compiler
+#   flags/libs to be tested by setting these environment variables.)
+#
+#   Also sets PTHREAD_CC to any special C compiler that is needed for
+#   multi-threaded programs (defaults to the value of CC otherwise). (This
+#   is necessary on AIX to use the special cc_r compiler alias.)
+#
+#   NOTE: You are assumed to not only compile your program with these flags,
+#   but also to link with them as well. For example, you might link with
+#   $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
+#
+#   If you are only building threaded programs, you may wish to use these
+#   variables in your default LIBS, CFLAGS, and CC:
+#
+#     LIBS="$PTHREAD_LIBS $LIBS"
+#     CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
+#     CC="$PTHREAD_CC"
+#
+#   In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
+#   has a nonstandard name, this macro defines PTHREAD_CREATE_JOINABLE to
+#   that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
+#
+#   Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the
+#   PTHREAD_PRIO_INHERIT symbol is defined when compiling with
+#   PTHREAD_CFLAGS.
+#
+#   ACTION-IF-FOUND is a list of shell commands to run if a threads library
+#   is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
+#   is not found. If ACTION-IF-FOUND is not specified, the default action
+#   will define HAVE_PTHREAD.
+#
+#   Please let the authors know if this macro fails on any platform, or if
+#   you have any other suggestions or comments. This macro was based on work
+#   by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
+#   from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
+#   Alejandro Forero Cuervo to the autoconf macro repository. We are also
+#   grateful for the helpful feedback of numerous users.

+   * If we get EAGAIN when writing to the target fd, we poll() on it until

+   *        return the number of sent bytes instead of an error because pread()
+   *        is, in theory, idempotent. However, special files in /dev or /proc
+   *        may support pread() but not necessarily return the same data on
+   *        successive reads.

+ *   nor from the environment variables as a whole.
+ *
+ * - When cmd.exe cannot read a directory, it will just skip it and go on
+ *   searching. However, unlike posix-y systems, it will happily try to run a
+ *   file that is not readable/executable; if the spawn fails it will not
+ *   continue searching.
+ *
+ * UNC path support: we are dealing with UNC paths in both the path and the

+/* Tests commented out with XXX are ones that are failing on Linux */
+
+/*
+ * Purpose of this test is to check semantics of starting and stopping
+ * prepare, check and idle watchers.
+ *
+ * - A watcher must be able to safely stop or close itself;
+ * - Once a watcher is stopped or closed its callback should never be called.
+ * - If a watcher is closed, it is implicitly stopped and its close_cb should
+ *   be called exactly once.
+ * - A watcher can safely start and stop other watchers of the same type.
+ * - Prepare and check watchers are called once per event loop iterations.
+ * - All active idle watchers are queued when the event loop has no more work
+ *   to do. This is done repeatedly until all idle watchers are inactive.
+ * - If a watcher starts another watcher of the same type its callback is not
+ *   immediately queued. For check and prepare watchers, that means that if
+ *   a watcher makes another of the same type active, it'll not be called until
+ *   the next event loop iteration. For idle. watchers this means that the
+ *   newly activated idle watcher might not be queued immediately.
+ * - Prepare, check, idle watchers keep the event loop alive even when they're
+ *   not active.
+ *
+ * This is what the test globally does:
+ *
+ * - prepare_1 is always active and counts event loop iterations. It also
+ *   creates and starts prepare_2 every other iteration. Finally it verifies
+ *   that no idle watchers are active before polling.
+ * - prepare_2 is started by prepare_1 every other iteration. It immediately
+ *   stops itself. It verifies that a watcher is not queued immediately
+ *   if created by another watcher of the same type.
+ * - There's a check watcher that stops the event loop after a certain number
+ *   of iterations. It starts a varying number of idle_1 watchers.
+ * - Idle_1 watchers stop themselves after being called a few times. All idle_1
+ *   watchers try to start the idle_2 watcher if it is not already started or
+ *   awaiting its close callback.
+ * - The idle_2 watcher always exists but immediately closes itself after
+ *   being started by a check_1 watcher. It verifies that a watcher is
+ *   implicitly stopped when closed, and that a watcher can close itself
+ *   safely.
+ * - There is a repeating timer. It does not keep the event loop alive
+ *   (ev_unref) but makes sure that the loop keeps polling the system for
+ *   events.

+ * The idea behind the test is as follows.
+ * Certain handle types are stored in a queue internally.
+ * Extra care should be taken for removal of a handle from the queue while iterating over the queue.
+ * (i.e., uv__queue_remove() called within uv__queue_foreach())
+ * This usually happens when someone closes or stops a handle from within its callback.
+ * So we need to check that we haven't screwed the queue on close/stop.
+ * To do so we do the following (for each handle type):
+ *  1. Create and start 3 handles (#0, #1, and #2).
+ *
+ *     The queue after the start() calls:
+ *     ..=> [queue head] <=> [handle] <=> [handle #1] <=> [handle] <=..
+ *
+ *  2. Trigger handles to fire (for uv_idle_t, uv_prepare_t, and uv_check_t there is nothing to do).
+ *
+ *  3. In the callback for the first-executed handle (#0 or #2 depending on handle type)
+ *     stop the handle and the next one (#1).
+ *     (for uv_idle_t, uv_prepare_t, and uv_check_t callbacks are executed in the reverse order as they are start()'ed,
+ *     so callback for handle #2 will be called first)
+ *
+ *     The queue after the stop() calls:
+ *                                correct foreach "next"  |
+ *                                                       \/
+ *     ..=> [queue head] <==============================> [handle] <=..
+ *          [          ] <-  [handle] <=> [handle #1]  -> [      ]
+ *                                       /\
+ *                  wrong foreach "next"  |
+ *
+ *  4. The callback for handle #1 shouldn't be called because the handle #1 is stopped in the previous step.
+ *     However, if uv__queue_remove() is not handled properly within uv__queue_foreach(), the callback _will_
+ *     be called.
