1.6 Applicability Statement

The DirectPlay 4 Protocol is activated only at the request of an application that is written for the IDirectPlay4 interface and written with the DirectX 6 Software Development Kit or a later version of the DirectX Software Development Kit (DirectX SDK). All of the functionality present in the DirectPlay 4 Protocol has been superseded by the DirectPlay 8 Protocol and, as such, the DirectPlay 4 Protocol is only to be used when the game has a requirement to interoperate with other DirectPlay 4 games.
