ABORT(3)						     Linux Programmer's Manual							  ABORT(3)

NAME
       abort - cause abnormal process termination

SYNOPSIS
       #include <stdlib.h>

       void abort(void);

DESCRIPTION
       The  abort() first unblocks the SIGABRT signal, and then raises that signal for the calling process.  This results in the abnormal termina-
       tion of the process unless the SIGABRT signal is caught and the signal handler does not return (see longjmp(3)).

       If the abort() function causes process termination, all open streams are closed and flushed.

       If the SIGABRT signal is ignored, or caught by a handler that returns, the abort() function will still terminate the process.  It does this
       by restoring the default disposition for SIGABRT and then raising the signal for a second time.

RETURN VALUE
       The abort() function never returns.
