DIEnumDevicesCallback
Application-defined callback function that receives Microsoft® DirectInput® devices as a result of a call to the IDirectInput8::EnumDevices method.
BOOL CALLBACK DIEnumDevicesCallback( LPCDIDEVICEINSTANCE lpddi, LPVOID pvRef );
Parameters
- lpddi
- Address of a DIDEVICEINSTANCE structure that describes the device instance.
- pvRef
- The application-defined value passed to EnumDevices or EnumDevicesBySemantics as the pvRef parameter.
Return Values
Returns DIENUM_CONTINUE to continue the enumeration or DIENUM_STOP to stop the enumeration.
Remarks
If a single hardware device can function as more than one DirectInput device type, it is enumerated as each device type that it supports. For example, a keyboard with a built-in mouse is enumerated twice: once as a keyboard and once as a mouse. The product GUID is the same for each device, however.
