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

       _exit, _Exit - terminate the current process

       #include <unistd.h>

       void _exit(int status);

       #include <stdlib.h>

       void _Exit(int status);

       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

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

       These functions do not return.

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

       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
       registered with atexit() or on_exit().  Whether it flushes standard I/O
       buffers and removes temporary files created with tmpfile(3)  is	imple-
       mentation  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 pending I/O may be cancelled upon _exit(),
       is implementation-dependent.
