5.2 Process Control

void Py_FatalError( const char *message): Print a fatal error message and kill the process. No cleanup is performed. This function should only be invoked when a condition is detected that would make it dangerous to continue using the Python interpreter; e.g., when the object administration appears to be corrupted. On Unix, the standard C library function abort() is called which will attempt to produce a core file.

void Py_Exit( int status): Exit the current process. This calls Py_Finalize() and then calls the standard C library function exit(status).

int Py_AtExit( void (*func) ()): Register a cleanup function to be called by Py_Finalize(). The cleanup function will be called with no arguments and should return no value. At most 32 cleanup functions can be registered. When the registration is successful, Py_AtExit() returns 0; on failure, it returns -1. The cleanup function registered last is called first. Each cleanup function will be called at most once. Since Python's internal finallization will have completed before the cleanup function, no Python APIs should be called by func.
