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