HRESULT hr;
IVIO_Device *pCoolantTemp;
VARIANT vDeviceData;
SHORT sCoolantTemp;
//Create an instance of the coolant temperature device and get its 
//IVIO_Device interface.
hr = CoCreateInstance(CLSID_VIO_COOLANT_TEMP, NULL,
                     CLSCTX_INPROC_SERVER, IID_VIODEVICE,
                     &pCoolantTemp);
//Ask the device for coolant temperature.
pCoolantTemp->GetData(&vDeviceData, 3000);
//Fetch the coolant temperature, in degrees Celsius, from the VARIANT.
sCoolantTemp = vDeviceData.iVal;
//Release the reference to the interface.
pCoolantTemp->Release();
