%/*
% * 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 (rpcport_t).
% *	0 is failure.  Otherwise returns the port number where the pair
% *	[prog, vers] is registered.  It may lie!
% *
% * PMAPPROC_DUMP() RETURNS (struct pmaplist_ptr)
% *
% * 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.
