ok..first off this is a win32 problem..
not really an opengl problem - but i am
constructing a new windowing wrapper lib for
use with opengl.
requires that you
set the dmDriverExtra member to indicate the size, in bytes, of the additional space available to receive private driver data.
what i want to know is simply..how can you
determine this value - or is this for use
with the cbWndExtra field of WindowClass???
Any help would be great...ive looked on
the microsoft dev site..but im still non
too sure about this...
