How to catch exit() in embedded C++ module from python code?

Question

I am embedding a c++ library (binding done with SIP) in my python application. Under certain circonstances (error cases), this library uses exit(), which causes my entire application to exit. Is there a way to catch this event, or do I need to modify the library to handle error cases differently ?

Thank you very much,

FWIW: The Google test library apparently has implemented a means of circumventing exit() calls. In unit tests, you can test for program exit using the ASSERT_EXIT macro. See gtest Advanced Guide — Hendrik

You must modify the source of the library. There is no "exception handling" in C and exit() does not return to the calling code under any circumstances.

+1. For some cases atexit() may help, but not if one needs to return to the calling code.

You can override the library linking with LD_LIBRARY_PATH and make your own exit function. Works fine.
