It is good to know that there is still a hope. In my case I could make it if only a ctype object would expose the address of the underlying C object. Thank you, Nadav. בתאריך 16 במרץ 2012 18:09, מאת Stéfan van der Walt <stefan@sun.ac.za>:

I have the following: A library of C function which is compiled into a dll A cython module with a function that expects as a parameter a C callback

My problem is how to make a python script to pass directly the address

of a C function from the dll to the cython function.

There's a Cython Enhancement Proposal for this, but it hasn't been implemented:

So, I don't think there's a cleaner way, unfortunately. It's great that you found a workaround, though--many people have been struggling with this issue.
