/*
 * Lookup server protocol - Internal to NeXT
 * Copyright (C) 1989 by NeXT, Inc.
 * 
 * This server uses a protocol based upon XDR layered on top of 
 * a mach rpc call. There are three procedures defined in the "lookup.defs"
 * file. A "lookup_link" operation takes a procedure string name and returns a
 * number to be used in the other two calls. "lookup_all" takes a procedure
 * number and XDR'd arguments and returns XDR'd results. It returns the
 * entire list of entries. "lookup_one" has a similar calling convention,
 * but returns only a single entry.
 *
 * The syntax of calls described here in comments looks like this:
 *
 *		result_type procedure_name(arg_type1 arg1, arg_type2 arg2, ...)
 *
 *	The arguments are assumed to be XDR'd in sequence and a single XDR'd
 * 	result is returned.
