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 (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.
