Structured Fault Handling For Linux

This library is a similar to SEH (Structured Exception Handling) under Windows. It's implemented using UNIX signal, therefore provide UNIX system capabilities to handle faults (such as SIGSEGV) using a try/catch manner.

Limitations

C and C++ backends are however separated. C++ backends was using standard try/catch (which is more modern) while C backends is using setjmp/longjmp. This brings incompability. Therefore, you have to make sure:

  1. Initialized the correct backends. Using sfh_init_sjlj() for C and sfh_init_cxx_throw() for C++.
  2. try/catch is identical to the backend on initialization. If initialized using sfh_init_sjlj() you can only try/catch in a C source, otherwise you can only try/catch (both __sfh_try / __sfh_cath and try / catch) in a C++ source.
