/*
* This file contains symbols and structures defining the rpc protocol
* between the yellowpages clients and the yellowpages servers. The servers
* are the yp database servers, and the yp binders.
*/
/*
* The following procedures are supported by the protocol:
*
* YPPROC_NULL() returns () takes nothing, returns nothing. This indicates
* that the yp server is alive.
*
* YPPROC_DOMAIN (char *) returns (bool_t) TRUE. Indicates that the
* responding yp server does serve the named domain; FALSE indicates no
* support.
*
* YPPROC_DOMAIN_NONACK (char *) returns (TRUE) if the yp server does serve
* the named domain, otherwise does not return. Used in the broadcast case.
*
* YPPROC_MATCH (struct ypreq_key) returns (struct ypresp_val). Returns the
* right-hand value for a passed left-hand key, within a named map and
* domain.
*
* YPPROC_FIRST (struct ypreq_nokey) returns (struct ypresp_key_val).
* Returns the first key-value pair from a named domain and map.
*
* YPPROC_NEXT (struct ypreq_key) returns (struct ypresp_key_val). Returns
* the key-value pair following a passed key-value pair within a named
* domain and map.
*
* YPPROC_XFR (struct ypreq_xfr) returns nothing. Indicates to a server that
* a map should be updated.
*
* YPPROC_CLEAR takes nothing, returns nothing. Instructs a yp server to
* close the current map, so that old versions of the disk file don't get
* held open.
*
* YPPROC_ALL (struct ypreq_nokey), returns
* union switch (bool more) {
* TRUE: (struct ypresp_key_val);
* FALSE: (struct) {};
* }
*
* YPPROC_MASTER (struct ypreq_nokey), returns (ypresp_master)
*
* YPPROC_ORDER (struct ypreq_nokey), returns (ypresp_order)
*
* YPPROC_MAPLIST (char *), returns (struct ypmaplist *)
