| 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. |
