The following example opens a CD audio device by specifying the device name.
UINT wDeviceID;
DWORD dwReturn;
MCI_OPEN_PARMS mciOpenParms;
// Opens a CD audio device by specifying the device name.
mciOpenParms.lpstrDeviceType = "cdaudio";
if (dwReturn = mciSendCommand(NULL, MCI_OPEN, MCI_OPEN_TYPE,
(DWORD)(LPVOID) &mciOpenParms))
// Error, unable to open device.
// The device opened successfully; get the device ID.
wDeviceID = mciOpenParms.wDeviceID;
