How to check what process opened a file? RRS feed

  • Question

  • Hello

    How to check from C++ in what process the file is opened? I am interested in Win7,8,10

    I would like to implement this 

    https://www.howtogeek.com/289333/how-to-tell-which-application-is-using-your-windows-pcs-webcam/

    I have already got camera, from camera I got Physical Device Object name. I checked in Process Explorer handles of process and found out that \Device\0000004d is file.

    How to check in what process the file \Device\0000004d is opened?

    Is it possible to determine by the file name the process that opened this file?

    Or I need to enumerate all the processes in system?

    Thanks

  • A way is with NtQuerySystemInformation & SystemHandleInformation

    (Restart Manager doesn't seem to find Devices on my Windows 10 OS)
