Hi guys, anyone got OpenGL interoperability
With the following patch I'm able to create a context sharing OpenGL

I took a look, and it doesn't seem like ctypes has much in the way of
C-accessible interface. One can of course emulate the Python code in
C++, but I'm not sure that's necessary. If you'd like guidance on how
do that, let me know.
Lastly, would you mind posting a fully functional example so that I
add it to the examples/ directory shipped with
PyOpenCL? I think that
could be rather helpful for people trying to follow in your footsteps.
Thanks for your work!
I make my code doing ctypes casting in C++ work, so there is no more the
need to do that casting explicitly in python code. (patch attached)
I also wrote a simple example working on linux (I have used glX APIs and
flags) showing the usage of GL interop. It draws the sin function using
coordinates that are generated directly by the video hardware.
I hope this will be useful :)
