FUNCTION
<<exit>>---end program execution
INDEX
exit
ANSI_SYNOPSIS
#include <stdlib.h>
void exit(int <[code]>);
TRAD_SYNOPSIS
#include <stdlib.h>
void exit(<[code]>)
int <[code]>;
DESCRIPTION
Use <<exit>> to return control from a program to the host operating
environment. Use the argument <[code]> to pass an exit status to the
operating environment: two particular values, <<EXIT_SUCCESS>> and
<<EXIT_FAILURE>>, are defined in `<<stdlib.h>>' to indicate success or
failure in a portable fashion.
<<exit>> does two kinds of cleanup before ending execution of your
program. First, it calls all application-defined cleanup functions
you have enrolled with <<atexit>>. Second, files and streams are
cleaned up: any pending output is delivered to the host system, each
open file or stream is closed, and files created by <<tmpfile>> are
deleted.
RETURNS
<<exit>> does not return to its caller.
PORTABILITY
ANSI C requires <<exit>>, and specifies that <<EXIT_SUCCESS>> and
<<EXIT_FAILURE>> must be defined.
Supporting OS subroutines required: <<_exit>>.
