class attributes and inner classes in C extensions

[harold fellermann]

Hello,

I just posted this question with a wrong subject... So here again with
a better one.

I am working on a C extension module that implements a bunch of
classes. Everything
works fine so far, but I cannot find any way to implement class
attributes or inner
classes. Consider you have the following lines of Python :

class Foo :
class Bar :
pass

spam = "foobar"

How can this class be translated to a C extension? Is there anything
comparable to
PyMethodDef that can be used for other attributes than functions?

Thanks for your help,
