       The  explain_dup_or_die  function is used to call the dup(2) system call.  On failure an explanation will
       be printed to  stderr,  obtained  from  explain_dup(3),  and  then  the  process  terminates  by  calling
       exit(EXIT_FAILURE).

       This function is intended to be used in a fashion similar to the following example:
              explain_dup_or_die(fildes);

       fildes  The fildes, exactly as to be passed to the dup(2) system call.

       Returns:
               This function only returns on success.  On failure, prints an explanation and exits.
