35 /*
36  * The following procedures are supported by the protocol:
37  *
38  * YPPROC_NULL() returns () takes nothing, returns nothing.  This indicates
39  * that the NIS server is alive.
40  *
41  * YPPROC_DOMAIN (char *) returns (bool_t) TRUE.  Indicates that the
42  * responding NIS server does serve the named domain; FALSE indicates no
43  * support.
44  *
45  * YPPROC_DOMAIN_NONACK (char *) returns (TRUE) if the NIS server does serve
46  * the named domain, otherwise does not return.  Used in the broadcast case.
47  *
48  * YPPROC_MATCH (struct ypreq_key) returns (struct ypresp_val).  Returns the
49  * right-hand value for a passed left-hand key, within a named map and
50  * domain.
51  *
52  * YPPROC_FIRST (struct ypreq_nokey) returns (struct ypresp_key_val).
53  * Returns the first key-value pair from a named domain and map.
54  *
55  * YPPROC_NEXT (struct ypreq_key) returns (struct ypresp_key_val).  Returns
56  * the key-value pair following a passed key-value pair within a named
57  * domain and map.
58  *
59  * YPPROC_XFR (struct ypreq_xfr) returns nothing.  Indicates to a server that
60  * a map should be updated.
61  *
62  * YPPROC_CLEAR	takes nothing, returns nothing.  Instructs a NIS server to
63  * close the current map, so that old versions of the disk file don't get
64  * held open.
65  *
66  * YPPROC_ALL (struct ypreq_nokey), returns
67  * 	union switch (bool more) {
68  *		TRUE:	(struct ypresp_key_val);
69  *		FALSE:	(struct) {};
70  *	}
71  *
72  * YPPROC_MASTER (struct ypreq_nokey), returns (ypresp_master)
73  *
74  * YPPROC_ORDER (struct ypreq_nokey), returns (ypresp_order)
75  *
76  * YPPROC_MAPLIST (char *), returns (struct ypmaplist *)
