I just wanted to know what's the difference between some functions:
the difference between the WNDCLASS class and the WNDCLASSEX class.
the difference between CreateWindow(...) and CreateWindowEx(..).
What's this Ex thing.
I used to use the non Ex things but now, I'm learning OpenGL and I see this things everywere. I think they may be a better way of creating windows which is more suitable for graphics. Correct me if i'm wrong.
