C++ In a Nutshell

Name

atexit function — Calls a function at program termination

Synopsis

extern "C"   int atexit(void (*func)(  ))
extern "C++" int atexit(void (*func)(  ))

The atexit function registers a parameterless function, func, which is called when the program exits normally.

Multiple functions can be registered, and registered functions are called in the opposite order of registration. A function can be registered more than once, in which case it will be called as many times as it was registered.

The atexit functions are not called if the program exits due to a signal, such as SIGABRT.
