/*
 * The following procedures are supported by the protocol:
 *
 * YPPROC_NULL() returns () takes nothing, returns nothing.  This indicates
 * that the NIS server is alive.
 *
 * YPPROC_DOMAIN (char *) returns (bool_t) TRUE.  Indicates that the
 * responding NIS server does serve the named domain; FALSE indicates no
 * support.
 *
 * YPPROC_DOMAIN_NONACK (char *) returns (TRUE) if the NIS server does serve
 * the named domain, otherwise does not return.  Used in the broadcast case.
 *
 * YPPROC_MATCH (struct ypreq_key) returns (struct ypresp_val).  Returns the
 * right-hand value for a passed left-hand key, within a named map and
 * domain.
 *
 * YPPROC_FIRST (struct ypreq_nokey) returns (struct ypresp_key_val).
 * Returns the first key-value pair from a named domain and map.
 *
 * YPPROC_NEXT (struct ypreq_key) returns (struct ypresp_key_val).  Returns
 * the key-value pair following a passed key-value pair within a named
 * domain and map.
 *
 * YPPROC_XFR (struct ypreq_xfr) returns nothing.  Indicates to a server that
 * a map should be updated.
 *
 * YPPROC_NEWXFR (struct ypreq_newxfr) returns nothing.  Indicates to a server
 * that a map should be updated. Uses protocol independent request struct.
 *
 * YPPROC_CLEAR	takes nothing, returns nothing.  Instructs a NIS server to
 * close the current map, so that old versions of the disk file don't get
 * held open.
 *
 * YPPROC_ALL (struct ypreq_nokey), returns
 * 	union switch (bool_t more) {
 *		TRUE:	(struct ypresp_key_val);
 *		FALSE:	(struct) {};
 *	}
 *
 * YPPROC_MASTER (struct ypreq_nokey), returns (ypresp_master)
 *
 * YPPROC_ORDER (struct ypreq_nokey), returns (ypresp_order)
 *
 * YPPROC_MAPLIST (char *), returns (struct ypmaplist *)
