* PMAPPROC_SET(struct pmap) returns (bool_t)

* [prog, vers, prot, port].
|
|
*
|
|
* PMAPPROC_UNSET(struct pmap) returns (bool_t)

|
* TRUE is success, FALSE is failure. Un-registers pair
|
|
* [prog, vers]. prot and port are ignored.
|
|
*
|
|
* PMAPPROC_GETPORT(struct pmap) returns (long unsigned).
|
|
* 0 is failure. Otherwise returns the port number where the pair
|
|
* [prog, vers] is registered. It may lie!
|
|
*
|
|
* PMAPPROC_DUMP() RETURNS (struct pmaplist *)
|

|
* usage: encapsulatedresults = PMAPPROC_CALLIT(prog, vers, proc, encapsulatedargs);
|
|
* Calls the procedure on the local machine. If it is not registered,
|
|
* this procedure is quite; ie it does not return error information!!!
|
|
* This procedure only is supported on rpc/udp and calls via

|
* rpc/udp. This routine only passes null authentication parameters.
