Opening a Simple Device by Using the Device-Type Constant

The following example opens a CD audio device by specifying a device-type constant.

UINT wDeviceID;
DWORD dwReturn;
MCI_OPEN_PARMS mciOpenParms;

// Opens a CD audio device by specifying a device-type constant.
mciOpenParms.lpstrDeviceType = (LPCSTR) MCI_DEVTYPE_CD_AUDIO;
if (dwReturn = mciSendCommand(NULL, MCI_OPEN,
    MCI_OPEN_TYPE | MCI_OPEN_TYPE_ID, (DWORD)(LPVOID) &mciOpenParms))
    
    // Error, unable to open device.
    
// The device opened successfully; get the device ID.
wDeviceID = mciOpenParms.wDeviceID;
