_EXIT(2)		   Linux Programmer's Manual		      _EXIT(2)

NAME
       _exit, _Exit - terminate	the current process

SYNOPSIS
       #include	<unistd.h>

       void _exit(int status);

       #include	<stdlib.h>

       void _Exit(int status);

DESCRIPTION
       The  function  _exit  terminates	the calling process "immediately". Any
       open file descriptors belonging to the process are closed; any children
       of the process are inherited by process 1, init,	and the	process's par-
       ent is sent a SIGCHLD signal.

       The value status	is returned to the parent  process  as	the  process's
       exit  status,  and  can	be  collected  using one of the	wait family of
       calls.

       The function _Exit is equivalent	to _exit.

RETURN VALUE
       These functions do not return.

CONFORMING TO
       SVr4, SVID, POSIX, X/OPEN, BSD 4.3.  The	function  _Exit()  was	intro-
       duced by	C99.

NOTES
       For  a  discussion  on the effects of an	exit, the transmission of exit
       status, zombie processes, signals sent, etc., see exit(3).

       The function _exit is like exit(), but does not call any	functions reg-
       istered with the	ANSI C atexit function,	nor any	registered signal han-
       dlers. Whether it flushes standard I/O buffers  and  removes  temporary
       files  created  with  tmpfile(3)	 is  implementation-dependent.	On the
       other hand, _exit does close open file descriptors, and this may	 cause
       an unknown delay, waiting for pending output to finish. If the delay is
       undesired, it may be useful to call  functions  like  tcflush()	before
       calling _exit().	 Whether any pending I/O is cancelled, and which pend-
       ing I/O may be cancelled	upon _exit(), is implementation-dependent.
