101 * Protocol for the local binder service, or pmap.
102 *
103 * Copyright (C) 1984, Sun Microsystems, Inc.
104 *
105 * The following procedures are supported by the protocol:
106 *
107 * PMAPPROC_NULL() returns ()
108 * takes nothing, returns nothing
109 *
110 * PMAPPROC_SET(struct pmap) returns (bool_t)
111 * TRUE is success, FALSE is failure. Registers the tuple
112 * [prog, vers, prot, port].
113 *
114 * PMAPPROC_UNSET(struct pmap) returns (bool_t)
115 * TRUE is success, FALSE is failure. Un-registers pair
116 * [prog, vers]. prot and port are ignored.
117 *
118 * PMAPPROC_GETPORT(struct pmap) returns (long unsigned).
119 * 0 is failure. Otherwise returns the port number where the pair
120 * [prog, vers] is registered. It may lie!
121 *
122 * PMAPPROC_DUMP() RETURNS (struct pmaplist *)
123 *
124 * PMAPPROC_CALLIT(unsigned, unsigned, unsigned, string<>)
125 * RETURNS (port, string<>);
126 * usage: encapsulatedresults = PMAPPROC_CALLIT(prog, vers, proc, encapsulatedargs);
127 * Calls the procedure on the local machine. If it is not registered,
128 * this procedure is quite; ie it does not return error information!!!
129 * This procedure only is supported on rpc/udp and calls via
130 * rpc/udp. This routine only passes null authentication parameters.
131 * This file has no interface to xdr routines for PMAPPROC_CALLIT.
132 *
133 * The service supports remote procedure calls on udp/ip or tcp/ip socket 111.
