void _Exit( int exit_code );		(since C99) (until C11)
_Noreturn void _Exit( int exit_code );		(since C11)

Causes normal program termination to occur without completely cleaning the resources.

Destructors of variables with automatic, thread local and static storage durations are not called. Functions passed to at_quick_exit() or atexit() are not called. Whether open resources such as files are closed is implementation defined. If exit_code is EXIT_FAILURE, an implementation-defined status, indicating unsuccessful termination, is returned. In other cases implementation-defined status value is returned.

Parameters

exit_code

-

exit status of the program

Return value

(none)
