Microsoft DirectPlay SDK
Welcome to the Microsoft® DirectPlay® Software Development Kit. DirectPlay is an API that simplifies application access to communication services. It provides a way for applications to communicate with each other independent of the underlying protocol, transport, or online service. This is especially useful for games. Real players, each on her or his own personal computer, can be gathered and launched into a game, without the game developer worrying about the connections.
