EXIT(3)		       FreeBSD Library Functions 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
     listed:

	   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 ISO/IEC 9899:1999 ("ISO C99").

HISTORY
     An	exit() function	first appeared as a system call	in Version 1 AT&T
     UNIX.  It has accepted the	status argument	since Version 2	AT&T UNIX.  In
     Version 7 AT&T UNIX, the bare system call was renamed to _exit(2).
