DDC_GetFilePropertyNames crashes MATLAB

[abdel2]

Whenever I use this function in MATLAB, it crashes with a segmentation fault error. There was already a thread about it over a year ago (http://forums.ni.com/ni/board/message?board.id=170&thread.id=289453&view=by_date_ascending&page=2|). Is this problem fixed by now?

I am using the following code:

           ppropnames=libpointer('stringPtrPtr',repmat(cellstr(repmat(',',1,255)),1,pnumprops.Value));       
           err = calllib('nilibddc','DDC_GetFilePropertyNames',file_handle,ppropnames,pnumprops.Value);           

I have tried other alternatives for declaring pointers, but none of them seem to work.

Does this example crash as well?

[abdel2]

Yes that examples works great, but it doesn't use the function I mentioned. I think this error occurs with any function that returns an array of strings (file, goup, and channel property names).

I am having similar issues returning to a stringPtrPtr. Has a workaround or fix been found for this problem?

Hello jyan2

Can you please describe your problem in more detail so I can better address this issue?  Is there an error code or pop-up generated when MATLAB crashes?  Thank you very much!
