IDirectInput8

Applications use the methods of the IDirectInput8 interface to enumerate, create, and retrieve the status of Microsoft® DirectInput® devices, initialize the DirectInput object, and invoke an instance of the Microsoft Windows® Control Panel.

IDirectInput8 supersedes the IDirectInput, IDirectInput2, and IDirectInput7 interfaces used in earlier versions of Microsoft DirectX®.

IDirectInput8 is an interface to a new class of object, represented by the class identifier CLSID_DirectInput8, and cannot be obtained by calling QueryInterface on an interface to objects of class CLSID_DirectInput. Instead, obtain the IDirectInput8 interface by using the DirectInput8Create function.

The methods of the IDirectInput8 interface can be organized into the following groups.

The IDirectInput interface, like all COM interfaces, inherits the IUnknown interface methods. The IUnknown interface supports the following three methods:

The LPDIRECTINPUT8 type is defined as a pointer to the IDirectInput8 interface:

typedef struct IDirectInput8    *LPDIRECTINPUT8;
