Mario,
Depending on the structure, you can simulate it using a character string. Some structures have pointers to other structures and these are more difficult. I've used to Ed Rauh's CLSHEAP and Christof Lange's STRUCT classes to help out with these situations. Both are availble from the Download section.

What structure are you trying to pass and what function are trying to pass it to?
