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 *).
