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 *).
