I tried SDL for the first time and in their documentation i found something i do not understand.

They make a pointer to the "SDL_Window" class called "window" and make the pointer null then later on they do this


Now i don't understand how this works because "SDL_CreateWindow" seems to be a totally different class. Shouldn't the pointer point to the same type? In this case, a "SDL_Window" object.

Does this work because "SDL_CreateWindow" is a child of "SDL_Window"?



Ok, i am totally confused right now. I just tried and i can't seem to do the same with a class created by me and that is just trying to do this

classOne* aClass = NULL;
aClass = classOne(23,14);

I also just realized that you should pass the address to the pointer but they don't do that...

How does this work? Its "SDL_CreateWindow" a function? I am so lost... :\
