_EXIT
NAME
_exit - terminate the current process
SYNOPSIS
#include <unistd.h>
void _exit(int status);
DESCRIPTION
_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 parent is sent a
SIGCHLD
signal.
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.
RETURN VALUE
_exit
never returns.
CONFORMING TO
SVr4, SVID, POSIX, X/OPEN, BSD 4.3
NOTES
_exit
does not call any functions registered with the ANSI C
atexit
function and does not flush standard I/O buffers. To do these things,
use
exit(3).
