示例1: GetDeviceInfo
HRESULT _stdcall GetDeviceInfo(LPDIDEVICEINSTANCEW a) {
return RealDevice->GetDeviceInfo(a);
}示例2: GetInputDevice
// **if passed an existing DirectInputDevice which matches gGuid
// unacquires it, and sets its cooperative level (reinitialize)
// **if the existing device does not match the passed gGuid, the existing device is released
// **if no device was passed or gGuid did not match
// searches for the controller matching gGuid in connected and available devices
// creates a DirectInputDevice
// sets its data format
// sets its cooperative level
// for joysticks, calls EnumSetObjectsAxis for each axis
// GetInputDevice always leaves the returned device in an UNACQUIRED state.
