Microsoft RPC Version 2.0
Copyright Microsoft Corp. 1992, 1993, 1994- 1996
rpcssm Example
FILE: rpcssmc.c
USAGE: rpcssmc -n network_address
-p protocol_sequence
-e endpoint
-o options
PURPOSE: Client side of RPC distributed application
FUNCTIONS: main() - binds to server and calls remote procedure
COMMENTS: This distributed application uses the rpcssm package.
