| 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>>. |
