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 termination 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 termi-
       nate 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.
