DirectPlay Interface Overviews
DirectPlay is composed of objects and interfaces based on the component object model (COM). COM is a foundation for an object-based system that focuses on the reuse of interfaces, and it is the model at the heart of OLE programming. It is also an interface specification from which any number of interfaces can be built.
New methods and functionality are exposed in COM through the use of new interfaces that are sequentially numbered. The current DirectPlay interface is called IDirectPlay3. The old interfaces, IDirectPlay and IDirectPlay2, still exist for backward compatibility with applications written to those interfaces.
This section contains general information about the following DirectPlay COM interfaces:
