Linux 2.6 - man page for abort (linux section 3)

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  sig-
       nal 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()  func-
       tion  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.

CONFORMING TO
