OpenGL device context ?

(1/1)

backspace:
Hi there.
I know with DirectX, with c++ i can get the device context handle, and do some stuff directly in the DX screen, I am however pretty new to OpenGL, and want to know if I can get the background buffer address, widow address, or whatever is appropriate, and do something similar. Why I wish to know this, is because there are some image manipulation routines that I used in DX, and wish to do the same - if it is possible with OGL. Is this at all possible with GLBasic?
Any help in this regard will be very much appreciated.

I've solved this problem by studying the TCL example in detail.

There's an OpenGL wrapper somewhere. gl.gbas
