There's an example in Demos/callback which shows
how you can go about this, but it relies on being
able to have an arbitrary pointer passed through
to the callback function.

It sounds like the callback mechanism you want to
use doesn't have provision for that, so you'll
just have to pass a fixed C function that calls
one particular Pyrex or Python function.
