* YPSERV PROTOCOL:
*
* ypserv supports the following procedures:
*
* YPPROC_NULL takes (void), returns (void).
* called to check if server is alive.
* YPPROC_DOMAIN takes (char *), returns (bool_t).
* true if ypserv serves the named domain.
* YPPROC_DOMAIN_NOACK takes (char *), returns (bool_t).
* true if ypserv serves the named domain.
* used for broadcasts, does not ack if ypserv
* doesn't handle named domain.
* YPPROC_MATCH takes (struct ypreq_key), returns (struct ypresp_val)
* does a lookup.
* YPPROC_FIRST takes (struct ypreq_nokey) returns (ypresp_key_val).
* gets the first key/datum from the map.
* YPPROC_NEXT takes (struct ypreq_key) returns (ypresp_key_val).
* gets the next key/datum from the map.
* YPPROC_XFR takes (struct ypreq_xfr), returns (void).
* tells ypserv to check if there is a new version of
* the map.
* YPPROC_CLEAR takes (void), returns (void).
* tells ypserv to flush it's file cache, so that
* newly transferred files will get read.
* YPPROC_ALL takes (struct ypreq_nokey), returns (bool_t and
* struct ypresp_key_val).
* returns an array of data, with the bool_t being
* false on the last datum. read the source, it's
* convoluted.
* YPPROC_MASTER takes (struct ypreq_nokey), returns (ypresp_master).
* YPPROC_ORDER takes (struct ypreq_nokey), returns (ypresp_order).
* YPPROC_MAPLIST takes (char *), returns (struct ypmaplist *).
