DESCRIPTION
       The  explain_tcflush_or_die  function  is  used	to  call  the tcflush(3) system call. On failure an explanation will be printed to stderr,
       obtained from the explain_tcflush(3) function, and then the process terminates by calling exit(EXIT_FAILURE).

       The explain_tcflush_on_error function is used to call the tcflush(3) system call. On failure an explanation  will  be  printed  to  stderr,
       obtained from the explain_tcflush(3) function, but still returns to the caller.
