%/*
% * The following procedures are supported by the protocol in version 3:
% *
% * RPCBPROC_NULL() returns ()
% * 	takes nothing, returns nothing
% *
% * RPCBPROC_SET(rpcb) returns (bool_t)
% * 	TRUE is success, FALSE is failure.  Registers the tuple
% *	[prog, vers, address, owner, netid].
% *	Finds out owner and netid information on its own.
% *
% * RPCBPROC_UNSET(rpcb) returns (bool_t)
% *	TRUE is success, FALSE is failure.  Un-registers tuple
% *	[prog, vers, netid].  addresses is ignored.
% *	If netid is NULL, unregister all.
% *
% * RPCBPROC_GETADDR(rpcb) returns (string).
% *	0 is failure.  Otherwise returns the universal address where the
% *	triple [prog, vers, netid] is registered.  Ignore address and owner.
% *
% * RPCBPROC_DUMP() RETURNS (rpcblist_ptr)
% *	used to dump the entire rpcbind maps
% *
% * RPCBPROC_CALLIT(rpcb_rmtcallargs)
% * 	RETURNS (rpcb_rmtcallres);
% * 	Calls the procedure on the remote machine.  If it is not registered,
% *	this procedure is quiet; i.e. it does not return error information!!!
% *	This routine only passes null authentication parameters.
% *	It has no interface to xdr routines for RPCBPROC_CALLIT.
% *
% * RPCBPROC_GETTIME() returns (int).
% *	Gets the remote machines time
% *
% * RPCBPROC_UADDR2TADDR(strint) RETURNS (struct netbuf)
% *	Returns the netbuf address from universal address.
% *
% * RPCBPROC_TADDR2UADDR(struct netbuf) RETURNS (string)
% *	Returns the universal address from netbuf address.
% *
% * END OF RPCBIND VERSION 3 PROCEDURES
% */
%/*
% * Except for RPCBPROC_CALLIT, the procedures above are carried over to
% * rpcbind version 4.  Those below are added or modified for version 4.
% * NOTE: RPCBPROC_BCAST HAS THE SAME FUNCTIONALITY AND PROCEDURE NUMBER
% * AS RPCBPROC_CALLIT.
% *
% * RPCBPROC_BCAST(rpcb_rmtcallargs)
% * 	RETURNS (rpcb_rmtcallres);
% * 	Calls the procedure on the remote machine.  If it is not registered,
% *	this procedure IS quiet; i.e. it DOES NOT return error information!!!
% *	This routine should be used for broadcasting and nothing else.
% *
% * RPCBPROC_GETVERSADDR(rpcb) returns (string).
% *	0 is failure.  Otherwise returns the universal address where the
% *	triple [prog, vers, netid] is registered.  Ignore address and owner.
% *	Same as RPCBPROC_GETADDR except that if the given version number
% *	is not available, the address is not returned.
% *
% * RPCBPROC_INDIRECT(rpcb_rmtcallargs)
% * 	RETURNS (rpcb_rmtcallres);
% * 	Calls the procedure on the remote machine.  If it is not registered,
% *	this procedure is NOT quiet; i.e. it DOES return error information!!!
% * 	as any normal application would expect.
% *
% * RPCBPROC_GETADDRLIST(rpcb) returns (rpcb_entry_list_ptr).
% *	Same as RPCBPROC_GETADDR except that it returns a list of all the
% *	addresses registered for the combination (prog, vers) (for all
% *	transports).
% *
% * RPCBPROC_GETSTAT(void) returns (rpcb_stat_byvers)
% *	Returns the statistics about the kind of requests received by rpcbind.
