- 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.
