_exit()                  Terminate Process without Cleanup
 
 #include   <process.h>
 #include   <stdlib.h>
 
 void       _exit(status);
 int        status;                      Exit status
 
    _exit() terminates the calling process and returns the low-byte of
    'status' (status & 0xFF) to the waiting parent process, if one
    exists.  Functions registered with ONEXIT are NOT executed, and
    stream buffers are not flushed.
 
 
    Returns:    There is no return value; exit() does not return to the
                calling process.  'status' is returned to the parent
                process. (The parent process is usually the operating
                system.)
 
      Notes:    exit() has a similar function as _exit(), but exit() does
                flush stream buffers and execute functions registered
                with onexit() before terminating.
 
  -------------------------------- Example ---------------------------------
 
    The following statements set the exit status to 1 if more than one
    command line argument is passed.
 
            #include <stdio.h>     /* for 'printf' */
            #include <stdlib.h>    /* for '_exit' (also in <process.h>) */
 
            main(argc, argv)
            int argc;
            char *argv[];
            {
                if (argc > 2) {
                   perror("no more than 1 command line parameter allowed\n");
                   _exit(1);   /* exit immediately */
                 }
                /* exit normally here with a status of 0 */
            }
