25.6.4 Aborting a Program

You can abort your program using the abort function. The prototype for this function is in stdlib.h.

— Function: void abort (void)

The abort function causes abnormal program termination. This does not execute cleanup functions registered with atexit or on_exit.
This function actually terminates the process by raising a SIGABRT signal, and your program can include a handler to intercept this signal; see Signal Handling.

Future Change Warning: Proposed Federal censorship regulations may prohibit us from giving you information about the possibility of calling this function. We would be required to say that this is not an acceptable way of terminating a program.
