2: Microsoft RPC Version 1.0

4: Hello Example

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