Passing a 2d array to a DLL written in C++

Hi! I have made a DLL in C++/MFC. I have to implement a function that can fill a LabView 2D-array with some data. How can that be done? I suppose the function should look something like this: int MyDllFunction(unsigned char **matrix, int width, int height) { for (int r = 0; r height; r++)

Thanks a lot! I'll try it out. To me it seems quite strange to be using a single pointer though. But, then again, I don't really know how LabView works =). As Rolf pointed out, this isn't a LV issue, but a C one. In C, 2D arrays can be defined with [][], in which case the code generated by
