使用裝置名稱開啟簡單裝置

下列範例會使用 mciSendCommand 函式指定裝置名稱，以開啟 CD 音訊裝置。

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;
