Who owns the memory in ctypes?

[Cem Karan]

Hi all, I'm hoping that this will be an easy question.

I have a pile of C code that I wrote that I want to interface to via the ctypes module (https://docs.python.org/3/library/ctypes.html).  The C code uses the Boehm-Demers-Weiser garbage collector (http://www.hboehm.info/gc/) for all of its memory management.  What I want to know is, who owns allocated memory?  That is, if my C code allocates memory via GC_MALLOC() (the standard call for allocating memory in the garbage collector), and I access some object via ctypes in python, will the python garbage collector assume that it owns it and attempt to dispose of it when it goes out of scope?

Ideally, the memory is owned by the side that created it, with the other side simply referencing it, but I want to be sure before I invest a lot of time interfacing the two sides together.

Thanks,
Cem Karan
