  18  * The following procedures are supported by the protocol:
  19  *
  20  * YPPROC_NULL() returns () takes nothing, returns nothing.  This indicates
  21  * that the NIS server is alive.
  22  *
  23  * YPPROC_DOMAIN (char *) returns (bool_t) TRUE.  Indicates that the
  24  * responding NIS server does serve the named domain; FALSE indicates no
  25  * support.
  26  *
  27  * YPPROC_DOMAIN_NONACK (char *) returns (TRUE) if the NIS server does serve
  28  * the named domain, otherwise does not return.  Used in the broadcast case.
  29  *
  30  * YPPROC_MATCH (struct ypreq_key) returns (struct ypresp_val).  Returns the
  31  * right-hand value for a passed left-hand key, within a named map and
  32  * domain.
  33  *
  34  * YPPROC_FIRST (struct ypreq_nokey) returns (struct ypresp_key_val).
  35  * Returns the first key-value pair from a named domain and map.
  36  *
  37  * YPPROC_NEXT (struct ypreq_key) returns (struct ypresp_key_val).  Returns
  38  * the key-value pair following a passed key-value pair within a named
  39  * domain and map.
  40  *
  41  * YPPROC_XFR (struct ypreq_xfr) returns nothing.  Indicates to a server that
  42  * a map should be updated.
  43  *
  44  * YPPROC_CLEAR takes nothing, returns nothing.  Instructs a NIS server to
  45  * close the current map, so that old versions of the disk file don't get
  46  * held open.
  47  *
  48  * YPPROC_ALL (struct ypreq_nokey), returns
  49  *      union switch (bool_t more) {
  50  *              TRUE:   (struct ypresp_key_val);
  51  *              FALSE:  (struct) {};
  52  *      }
  53  *
  54  * YPPROC_MASTER (struct ypreq_nokey), returns (ypresp_master)
  55  *
  56  * YPPROC_ORDER (struct ypreq_nokey), returns (ypresp_order)
  57  *
  58  * YPPROC_MAPLIST (char *), returns (struct ypmaplist *)
