- USAGE: hellos -p protocol_sequence
- -e endpoint
- -m max calls
- -n min calls
- -f flag for RpcServerListen
- PURPOSE: Server side of RPC distributed application hello
- FUNCTIONS: main() - registers server as RPC server
- COMMENTS: This version of the distributed application that prints
- "hello, world" (or other string) on the server features
- a client that manages its connection to the server.
- It uses the binding handle hello_IfHandle, defined in
- the file hello.h.
