EXIT(3)                   OpenBSD Programmer's Manual                  EXIT(3)

NAME
     exit - perform normal program termination

SYNOPSIS
     #include <stdlib.h>

     void
     exit(int status);

DESCRIPTION
     The exit() function terminates a process.

     Before termination it performs the following functions in the order list-
     ed:

           1.   Call the functions registered with the atexit(3) function, in
                the reverse order of their registration.

           2.   Flush all open output streams.

           3.   Close all open streams.

           4.   Unlink all files created with the tmpfile(3) function.

     Following this, exit() calls _exit(2).  Note that typically _exit(2) only
     passes the lower 8 bits of status on to the parent, thus negative values
     have less meaning.

RETURN VALUES
     The exit() function never returns.

SEE ALSO
     _exit(2), atexit(3), intro(3), sysexits(3), tmpfile(3)

STANDARDS
     The exit() function conforms to ANSI X3.159-1989 (``ANSI C'').

OpenBSD 3.4                      June 29, 1991                               1
