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 (as though raise(3) was called).  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.
