+ * PMAPPROC_NULL() returns ()
+ * takes nothing, returns nothing
+ *
+ * PMAPPROC_SET(struct pmap) returns (bool_t)
+ * TRUE is success, FALSE is failure. Registers the tuple

+ *
+ * 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 *)
+ *
+ * PMAPPROC_CALLIT(unsigned, unsigned, unsigned, string<>)
+ * RETURNS (port, string<>);
+ * 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.
+ * This file has no interface to xdr routines for PMAPPROC_CALLIT.
