怎么获得真实的相机状态

你好，
我正在使用librealsense 2.16.0.221和D430相机型号。
我想知道，从我的应用程序来看，相机是否已经在使用中（例如，在RealSense Viewer内或其他应用程序中打开）。
是否有用于此目的的相机选项？
我无法在这方面找到任何东西，我发现唯一的东西是选项RS2_CAMERA_INFO_CAMERA_LOCKED但我的设备不支持它（我用rs2 :: device :: supports（）调用检查它）。
感谢您的支持！

Hello,
I'm using librealsense 2.16.0.221 and a D430 camera model. I'd like to know, from my application, wheter or not the camera is already in use (e.g., opened inside the RealSense Viewer or by another app).
Is there a camera option for this purpose?
I was not able to find anything in this regard, the only thing I found is the option RS2_CAMERA_INFO_CAMERA_LOCKED but it is not supported by my device (I checked it with the rs2::device::supports() call).

Thanks for your support!
