- Microsoft RPC Version 2.0
- Copyright Microsoft Corp. 1992, 1993, 1994- 1996
- whello Example
-
- FILE: whellos.c
-
- USAGE: whellos -p protocol_sequence
- -e endpoint
- -m max calls
- -n min calls
- -f flag for RpcServerListen
-
- PURPOSE: Server side of RPC distributed application whello
-
- FUNCTIONS: main() - registers server as RPC server
-
- COMMENTS: Windows version of the "Hello, World" example.
-
- Windows can have several copies of your application
- running at the same time. The variable hInst keeps
- track of which instance the application is so that
- processing will be to the correct window.
