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