Multiple warnings when loading library from MATLAB

Hello,

I am using MATLAB 2010a to load the McsUsbDLL as in the examples provided and I get lots of warnings about unknown types.

What gives?


----------------------------------------------
Here is my MATLAB code:

if ~libisloaded('McsUsbDLL')
[notfound, warnings] = loadlibrary('McsUsbDLL', 'McsUsbDLL.h','alias','McsUsbDLL')
notfound
warnings
end
-----------------------------------------------


Here are the various warnings generated:

Warning: The data type 'error' used by function McsUsb_UploadFirmware does not exist.
> In loadlibrary at 461
In SetUpEleStimEnvironment at 16

notfound =

Empty cell array: 0-by-1


warnings =

Any help would be greatly appreciated.

You can safely ingnore this warnings, when no function is involved that you need.
On the other hand you can add the appropriate typedef in the McsUsbDLL.h file:

• typedef unsigned long int uint64;
  
• typedef int int32;
  
• typedef int McsUsbFactoryProgressCallback;
  
• typedef unsigned short USHORT;
  
• typedef short SHORT;

Thank you for the hint. We will fix this issue in the next version of MC_Stimulus

Dear Jens,

Thank you very much for your prompt response.

I would also like to know if there is some documentation on the use of the different functions in McsUsbDLL library. Some functions are self explanatory but many are not. I have looked at the 2 Matlab examples provided but these use only a few of the available functions.

Thanks,

Nicolas
