* pmap_prot.h
* Protocol for the local binder service, or pmap.
*
* Copyright (C) 1984, Sun Microsystems, Inc.
*
* The following procedures are supported by the protocol:
*
* PMAPPROC_NULL() returns ()
* takes nothing, returns nothing
*
* PMAPPROC_SET(struct pmap) returns (bool_t)
* TRUE is success, FALSE is failure. Registers the tuple
* [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 *)
*
* 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.
*
* The service supports remote procedure calls on udp/ip or tcp/ip socket 111.
