DWORD dwReturn;
MCI_OPEN_PARMS mciOpenParms;
 
// Opens a waveform-audio device by specifying the device and

mciOpenParms.lpstrDeviceType = "waveaudio";
mciOpenParms.lpstrElementName = "timpani.wav";

if (dwReturn = mciSendCommand(NULL, MCI_OPEN,
    MCI_OPEN_TYPE | MCI_OPEN_ELEMENT, (DWORD)(LPVOID) &mciOpenParms))
{
    
    // Error, unable to open device.
    
}

// The device opened successfully; get the device ID.
wDeviceID = mciOpenParms.wDeviceID;
