Calling EnumDisplayDevices from a UMDF driver fails RRS feed

  • Question

  • Hi,

    Am I expected to be able to call EnumDisplayDevices from a UMDF driver?

    I kinda expect it to work since it's not a KMDF driver, but it returns 0 and GetLastError() is either 0 (no error) or 997 (outstanding overlapped I/O - something I don't explicitly use), depending on where in my code I call EnumDisplayDevices.
