No matter why I tried I keep getting ADL_ERR_INVALID_PARAM_SIZE

These are the relevant structs I have

[StructLayout(LayoutKind.Sequential)]
internal struct PerformanceLevel
{
      public int iEngineClock;
      public int iMemoryClock;
}

[StructLayout(LayoutKind.Sequential)]
internal struct StateInfo
{
      public int NumberOfPerformanceLevels;
      public int ExtValue;
      public int ExtMask;
      [MarshalAs(UnmanagedType.ByValArray, SizeConst = 1)]
      public PerformanceLevel[] aLevels;
}

Below ADL SDK sample demonstrates how to use the above API. Please try this sample and if it works, modify your code accordingly.

I've read all the examples, the OverdriveN.cpp example works when I run it. But I can't my equivalent in C# to work.

in C++

C#

I've made some progress, ADL is returning 0 now. But I'm having a hard time converting the aLevels from a pointer to an array. Will post if I'm successful or if I fail and need some help

Good to hear about this progress. I don't know C#, so can't help you in this regard. Please check with the C# community users if they can help you to convert this C/C++ structure to equivalent C#. If you face any other ADL related issue, please let us know.

Thanks.
