You can see how we did this before with the opencv wrappers starting at line 117 of this file: https://github.com/scikits-image/scikits-image/blob/0.3.1/scikits/image/open... On Sat, Mar 17, 2012 at 2:35 PM, Chris Colbert <sccolbert@gmail.com> wrote:

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,

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

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.
