以下示例将时间格式设置为帧,并在设备使用 mciSendCommand 函数播放时获取当前位置。

MCI_DGV_SET_PARMS mciSet; 
MCI_DGV_STATUS_PARMS mciStatus; 
 
// Put in frame mode. 
mciSet.dwTimeFormat = MCI_FORMAT_FRAMES; 
mciSendCommand(wDeviceID, MCI_SET, 
    MCI_SET_TIME_FORMAT, 
    (DWORD)(LPSTR)&mciSet); 
 
mciStatus.dwItem = MCI_STATUS_MODE; 
mciSendCommand(wDeviceID, MCI_STATUS, 
    MCI_STATUS_ITEM, 
    (DWORD)(LPSTR)&mciStatus); 
 
// If device is playing, get the position. 
if (mciStatus.dwReturn == MCI_MODE_PLAY)
{ 
    mciStatus.dwItem = MCI_STATUS_POSITION; 
    mciSendCommand(wDeviceID, MCI_STATUS, MCI_STATUS_ITEM, 
        (DWORD)(LPSTR)&mciStatus); 
 
    // Update the position from mciStatus.dwReturn. 
}
