Thanks for reply. I think it is pointing to array3D_t. Then I am assigning the value of sizeDim1 to size[0].



(* array3D).size[0] = sizeDim1;


If this cannot be done....

Thank you very much, oogabooga.

Now the code is running as expected. But, with your explanation I have lost the notion of pointers. :confused:
