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

NAME
       _exit, _Exit - terminate the calling process

SYNOPSIS
       #include <unistd.h>

       void _exit(int status);

       #include <stdlib.h>

       void _Exit(int status);

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

       _Exit():
	   _ISOC99_SOURCE || _POSIX_C_SOURCE >= 200112L

DESCRIPTION
       The function _exit() terminates the calling process "immediately".  Any
       open file descriptors belonging to the process are closed.   Any	 chil‐
       dren  of	 the process are inherited by init(1) (or by the nearest "sub‐
       reaper"	process	 as  defined  through  the   use   of	the   prctl(2)
       PR_SET_CHILD_SUBREAPER  operation).   The  process's  parent  is sent a
       SIGCHLD signal.

       The value status & 0377 is  returned  to	 the  parent  process  as  the
       process's  exit	status,	 and can be collected using one of the wait(2)
       family of calls.

       The function _Exit() is equivalent to _exit().

RETURN VALUE
       These functions do not return.

CONFORMING TO
       POSIX.1-2001, POSIX.1-2008, SVr4, 4.3BSD.   The	function  _Exit()  was
       introduced by C99.

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

       The function _exit() is like exit(3), but does not call	any  functions
       registered with atexit(3) or on_exit(3).	 Open stdio(3) streams are not
       flushed.	 On the other hand, _exit() does close open file  descriptors,
       and this may cause an unknown delay, waiting for pending output to fin‐
       ish.  If the delay is undesired, it may be  useful  to  call  functions
       like  tcflush(3)	 before	 calling  _exit().  Whether any pending I/O is
       canceled, and which pending I/O may be canceled upon _exit(), is imple‐
       mentation-dependent.

   C library/kernel differences
       In  glibc  up  to version 2.3, the _exit() wrapper function invoked the
       kernel system call of the same name.   Since  glibc  2.3,  the  wrapper
       function	 invokes  exit_group(2),  in  order  to	 terminate  all of the
       threads in a process.
