You are mistaken on two counts.

You can't pickle a CObject, you'd have to create a custom type (one

Thanks everyone.
Finally, I used Falcolas suggestion and took into consideration
sturlamolden's comments.

Formally, you should cast the pointer to Py_intptr_t, as it has t

Hello
From my C extension module I want to store a C pointer in a given PyObject.
The only way I figure how to do it is to use Py_BuildValues and store the
poiner casted to Py_ssize_t, thus:
Py_BuildValues("n", (Py_ssize_t)my_ptr)
Can it be done differently?
