EXIT(3) NEWLIB EXIT(3)NAME
2.17 `exit'--end program execution
SYNOPSIS
#include <stdlib.h>
void exit(int CODE);
DESCRIPTION
Use `exit' to return control from a program to the host operating envi‐
ronment. 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 porta‐
ble 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'.
SEE ALSOexit is part of the library. The full documentation for is maintained
