Description

TSimpleIPCServer is the server side of the simple IPC communication protocol. The server program should create a TSimpleIPCServer instance, set its ServerID property to a unique name for the system, and then set the Active property to True (or call StartServer).

After the server was started, it can check for availability of messages with the PeekMessage call, and read the message with ReadMessage.
