*
|
||
|
|
* YPPROC_NULL() returns () takes nothing, returns nothing. This indicates
|
||
|
|
* that the NIS server is alive.
|
||
|
|
*
|
||
|
|
* YPPROC_DOMAIN (char *) returns (bool_t) TRUE. Indicates that the
|
||
|
|
* responding NIS server does serve the named domain; FALSE indicates no
|
||
|
|
* support.
|
||
|
|
*
|
||
|
|
* YPPROC_DOMAIN_NONACK (char *) returns (TRUE) if the NIS 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 NIS 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
