34  * YPSERV PROTOCOL:
35  *
36  * ypserv supports the following procedures:
37  *
38  * YPPROC_NULL		takes (void), returns (void).
39  *			called to check if server is alive.
40  * YPPROC_DOMAIN	takes (char *), returns (bool_t).
41  *			true if ypserv serves the named domain.
42  * YPPROC_DOMAIN_NOACK	takes (char *), returns (bool_t).
43  *			true if ypserv serves the named domain.
44  *			used for broadcasts, does not ack if ypserv
45  *			doesn't handle named domain.
46  * YPPROC_MATCH		takes (struct ypreq_key), returns (struct ypresp_val)
47  *			does a lookup.
48  * YPPROC_FIRST		takes (struct ypreq_nokey) returns (ypresp_key_val).
49  *			gets the first key/datum from the map.
50  * YPPROC_NEXT		takes (struct ypreq_key) returns (ypresp_key_val).
51  *			gets the next key/datum from the map.
52  * YPPROC_XFR		takes (struct ypreq_xfr), returns (void).
53  *			tells ypserv to check if there is a new version of
54  *			the map.
55  * YPPROC_CLEAR		takes (void), returns (void).
56  *			tells ypserv to flush its file cache, so that
57  *			newly transferred files will get read.
58  * YPPROC_ALL		takes (struct ypreq_nokey), returns (bool_t and
59  *			struct ypresp_key_val).
60  *			returns an array of data, with the bool_t being
61  *			false on the last datum. read the source, it's
62  *			convoluted.
63  * YPPROC_MASTER	takes (struct ypreq_nokey), returns (ypresp_master).
64  * YPPROC_ORDER		takes (struct ypreq_nokey), returns (ypresp_order).
65  * YPPROC_MAPLIST	takes (char *), returns (struct ypmaplist *).
