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 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.
