2.1 _Exit—end program execution with no cleanup processing

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 differs from exit in that it does not run any application-defined cleanup functions registered with atexit and it does not clean up files and streams. It is identical to _exit.


Returns
_Exit does not return to its caller.


Portability
_Exit is defined by the C99 standard.

Supporting OS subroutines required: _exit.
