C++ Pointers Help

[vgvgf]

I'm working on a c++ programm since some days, all was going well, but now I have found some little trouble with pointers. I am working with SDL and I want is to convert a pointer to a struct(namely SDL_Surface) to an int(or other numeric type). And also convert the int to the pointer again.

SDL_Surface* pic = NULL;

pic = IMG_Load("test.png"); // Loads the image

int pointer;

pointer = {pic to int}; // Pointer to int, what {pic to int} should be?

SDL_Surface* pic2 = pointer; // Int to pointer

I still don't know if that's possible. If not, I will have to do things in an other much complicated way...

Cast the address of the pointer to int.

int pointer = (int) &pic;

I have tried both "(int) pic" and "&pic", but never tried both things together, hehe. Thanks Zeriab! Now I can continue with my project
