4: Cluuid Example

6: FILE: cluuidc.c

8: USAGE: cluuidc -n network_address
9: -p protocol_sequence
10: -e endpoint
11: -o options
12: -s string_displayed_on_server
13: -u client object uuid
14:
15: PURPOSE: Client side of RPC distributed application
16:
17: FUNCTIONS: main() - binds to server and calls remote procedure
18:
19: COMMENTS: This distributed application prints a string such as
20: "hello, world" on the server. The client manages its
21: connection to the server. The client uses the implicit
22: binding handle ImpHandle defined in the file cluuid.h.
