Your sparse_fd variable should be used to initialize the PointerByReference, and you should update sparse_fd from PointerByReference.getValue() after a call to change_to_next_files.

Hello, I've read that if therer's a File * in C, it's replaced by a Pointer in Java. My C program is like that: File * sparse_fd; bunch_of_ray(sparse_fd); (the prototype is: void bunch_of_ray(File *f) change_to_next_files (&sparse_fd); (the prototype is void change_to_next_files(File ** a)

I don't know how to declare sparse_fd. If is was used just as a File *, I'd have declared it as a Pointer, and if it was just used as a File ** (with &sparse_fd) I'd have declared it as a PointerByReference (I think). But as it's used as both File * and File **, I don't know what to do.

Thanks.
