  36  * YPSERV PROTOCOL:
  37  *
  38  * ypserv supports the following procedures:
  39  *
  40  * YPPROC_NULL          takes (void), returns (void).
  41  *                      called to check if server is alive.
  42  * YPPROC_DOMAIN        takes (char *), returns (bool_t).
  43  *                      true if ypserv serves the named domain.
  44  * YPPROC_DOMAIN_NOACK  takes (char *), returns (bool_t).
  45  *                      true if ypserv serves the named domain.
  46  *                      used for broadcasts, does not ack if ypserv
  47  *                      doesn't handle named domain.
  48  * YPPROC_MATCH         takes (struct ypreq_key), returns (struct ypresp_val)
  49  *                      does a lookup.
  50  * YPPROC_FIRST         takes (struct ypreq_nokey) returns (ypresp_key_val).
  51  *                      gets the first key/datum from the map.
  52  * YPPROC_NEXT          takes (struct ypreq_key) returns (ypresp_key_val).
  53  *                      gets the next key/datum from the map.
  54  * YPPROC_XFR           takes (struct ypreq_xfr), returns (void).
  55  *                      tells ypserv to check if there is a new version of
  56  *                      the map.
  57  * YPPROC_CLEAR         takes (void), returns (void).
  58  *                      tells ypserv to flush it's file cache, so that
  59  *                      newly transferred files will get read.
  60  * YPPROC_ALL           takes (struct ypreq_nokey), returns (bool_t and
  61  *                      struct ypresp_key_val).
  62  *                      returns an array of data, with the bool_t being
  63  *                      false on the last datum. read the source, it's
  64  *                      convoluted.
  65  * YPPROC_MASTER        takes (struct ypreq_nokey), returns (ypresp_master).
  66  * YPPROC_ORDER         takes (struct ypreq_nokey), returns (ypresp_order).
  67  * YPPROC_MAPLIST       takes (char *), returns (struct ypmaplist *).
