abort - Abnormal program termination

Definition	#include <stdlib.h> void abort(void); (not C11) _Noreturn void abort(void); (C11) abort triggers the SIGABRT signal. If the program does not provide a routine for signal handling or if such a routine returns to the point of the interrupt, the program is aborted with _exit(-1). Any termination routines registered with atexit or  at_quick_exit are not called and open files are not closed.
