simple-chat

Big thanks to Beej's Guide to Networking Programming for help and inspiration. Buy his book!

In particular, see his section on the select system call and example code.

Why use select, you may be thinking to yourself? After all, it only supports a limited number of connections (1024).

Well, I don't think I even know that many people in the whole, wide world. It's safe to say that even that limited number won't be on simple-chat all at the same time.

Installation

make build

Only tested on Linux. It uses select, so it should be portable :)

Examples

Start the server and connect via telnet or netcat. By default it binds to port 3333, but this can be changed by specifying a different port number.

Start the server:

./simple_chat 1992
Simple chat server started on port 1992...
Clients can connect using telnet, i.e., `telnet 127.0.0.1 1992`

Connect a client:

telnet 127.0.0.1 1992

Or:

nc 127.0.0.1 1992
