EXIT(2)                   386BSD Programmer's Manual                   EXIT(2)

NAME
     exit - terminate the calling process

SYNOPSIS
     #include <unistd.h>

     void volatile
     exit(int status)

DESCRIPTION
     The exit() function terminates a process with the following
     consequences:

     o   All of the descriptors open in the calling process are closed.  This
         may entail delays, for example, waiting for output to drain; a
         process in this state may not be killed, as it is already dying.

     o   If the parent process of the calling process has an outstanding wait
         call or is interested in the SIGCHLD signal, it is notified of the
         calling process's termination and the status area is set as defined
         by wait(2).

     o   The parent process-ID of all of the calling process's existing child
         processes are set to 1; the initialization process (see the
         DEFINITIONS section of intro(2))  inherits each of these processes.
         Any stopped children are restarted with a hangup signal (SIGHUP).

     Most C programs call the library routine exit(3),  which flushes buffers,
     closes streams, unlinks temporary files, etc., before calling exit().

RETURN VALUE
     exit() can never return.

HISTORY
     An exit function call appeared in Version 6 AT&T UNIX.
