Microsoft RPC Version 2.0
Copyright Microsoft Corp. 1992, 1993, 1994- 1996
Cluuid Example
FILE: cluuidc.c
USAGE: cluuidc -n network_address
-p protocol_sequence
-e endpoint
-o options
-s string_displayed_on_server
-u client object uuid
PURPOSE: Client side of RPC distributed application
FUNCTIONS: main() - binds to server and calls remote procedure
COMMENTS: This distributed application prints a string such as
"hello, world" on the server. The client manages its
connection to the server. The client uses the implicit
binding handle ImpHandle defined in the file cluuid.h.
