 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 *).
