  20.      The _eeee_nnnn_aaaa_bbbb_llll_eeee_oooo_kkkk function allows the service routine of the queue pointed to
  21.      by _q to be rescheduled for service.  It cancels the effect of a previous
  22.      use of the _nnnn_oooo_eeee_nnnn_aaaa_bbbb_llll_eeee(D3) function on _q.

  41.      The _qqqq_rrrr_eeee_ssss_tttt_aaaa_rrrr_tttt routine uses two STREAMS functions to re-enable a queue that
  42.      has been disabled.  The _eeee_nnnn_aaaa_bbbb_llll_eeee_oooo_kkkk function removes the restriction that
  43.      prevented the queue from being scheduled when a message was enqueued.
  44.      Then, if there are messages on the queue, it is scheduled by calling
  45.      _qqqq_eeee_nnnn_aaaa_bbbb_llll_eeee(D3).
