_Exit—end program execution with no cleanup processing #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.
