  • 项目

以下示例通过使用 mciSendCommand 函数指定设备名称来打开 CD 音频设备。

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;
