EXT Library - atexit

The lib::atexit is a reentrancy-safe version of std::atexit with support for additional parameter.

---

Interface:

void lib::atexit (void (* callback) (void *), void * param);

• void (* callback) (void *)
  A pointer to function to be called when the control leaves the main function.
• void * param
  An opaque pointer for the callback function to be called with.

Details:

The lib::atexit is implemented in terms of std::atexit. The whole mechanism is registered to be invoked when the application exists using std::atexit the first time the lib::atexit is called. Thus, there must be at least one position remaining in the std::atexit implementation when the lib::atexit is called for it to work properly.

You will need to include "ext/lib_bits/atexit.cpp" into your project in order to use lib::atexit.

Remarks

The C standard demands at least 32 positions for std::atexit to be available, but in C++, some of these are usually used for global destructors (GCC).
