SYNOPSIS
#include
<stdlib.h>
void exit(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.
COMPLIANCE
ANSI C requires exit,
and specifies that EXIT_SUCCESS
and EXIT_
FAILURE
must be defined.
Supporting OS subroutines required: _exit.
