2. What is it? Sample Application developed in C++ Can be used as a Client/Server framework Works on GP HMP 2.7 platforms (Windows)

3. Overall Architecture Description There are 3 main project in the rpcSample solution gpaoh Contains the gpaoh.idl file. The Midl compiler creates stub code for the gpaohServer and gpaohClient applications can communicate which each other. gpaohServer The server responds to the clients request. It also contains an event queue mechanism to distribute events to each client. gpaohClient The client makes remote procedure calls to the server via the APIs defined in the gpaoh.idl file.

4.
