CSharp wrapper for dwf returns wrong error codes

[blackt1ger]

After spending the day trying to troubleshoot while dwf.FDwfEnum doesn't work, updating adept2, updating WaveForms, rebooting computer it appears that I am receiving error codes when I shouldn't.   Sadly, you don't document  your CSharp wrapper, I assume it comports to the C dll externs documentation

How should I check for errors  or am I doing something wrong?

----- partial code snip of a routine that returns a list of devices

                int devices = 0;
                var res     = dwf.FDwfEnum(dwf.enumfilterAll, out devices);

                // res is always "1" for me.   But should be "0" for no error 

                // if I ignore the error, I do find that "devices" correctly returns "1".
                if (res != 0)
                {
                    Debug.WriteLine(DigilentWaveForms.LastError);
                    return null;
                }

Hi @blackt1ger

Return of 1 is true, is ok. The 0/false would indicate error.
