iddcx uses IddCxMonitorSetupHardwareCursor to report an error

Question

system:windows11 development tools:Visual Studio 2019 iddcx Version:1.4 The reference code is as follows, Run the code and report an error:NewMonitorArrives IddCxMonitorSetupHardwareCursor Fail 0xc000000d(STATUS_INVALID_PARAMETER). May I ask how to use the IddCxMonitorSetupHardwareCursor() function correctly to configure successfully.

Status = IddCxMonitorArrival(MonitorCreateOut.MonitorObject, &ArrivalOut);

if (NT_SUCCESS(Status))

{

    IDARG_IN_SETUP_HWCURSOR cursorArgs;

    ZeroMemory(&cursorArgs, sizeof(cursorArgs));

    cursorArgs.hNewCursorDataAvailable = NULL; //CreateEvent(NULL, TRUE, FALSE, _T("iddCursorDataAvailable"));

    cursorArgs.CursorInfo.Size = sizeof(IDDCX_CURSOR_CAPS);

    cursorArgs.CursorInfo.ColorXorCursorSupport = IDDCX_XOR_CURSOR_SUPPORT_NONE;

    cursorArgs.CursorInfo.AlphaCursorSupport = true;

    cursorArgs.CursorInfo.MaxX = 128;

    cursorArgs.CursorInfo.MaxY = 128;

    Status = IddCxMonitorSetupHardwareCursor(MonitorCreateOut.MonitorObject, &cursorArgs);

    if (NT_SUCCESS(Status))

    {

        KdPrint(("%!FUNC! IddCxMonitorSetupHardwareCursor ok \n"));

    }

    else

    {

        KdPrint(("%!FUNC! IddCxMonitorSetupHardwareCursor Fail %!STATUS!", Status));

    }

}
