Data in frame buffer

what is the format of date in frame buffer in case of opengl.I wants to know how data arrange in frame buffer?

with thanks

Really to say, I don’t know.
But I am shure, it depends of driver/card.

Why do you need it? You still can’t access framebuffer!

It is something related to pixelformatting.

What do you mean by ‘pixelformating’?
