class Example
{
    static unsafe bool TryExtractMyCounterValue(FrameDataView frameData, string counterName, out int counterValue)
    {
        var counterMarkerId = frameData.GetMarkerId(counterName);
        void* valuePtr = frameData.GetCounterValuePtr(counterMarkerId);
        if (valuePtr == null)
        {
            counterValue = 0;
            return false;
        }

        counterValue = *(int*)valuePtr;
        return true;
    }
