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).
