I get the impression where ctypes is good for accessing native C libraries from
within python, the data-type object is meant to add a more direct way to share
native python object's *data* with C (or other languages) in a more efficient
way. For data that can be represented well in continuous memory address's, it
lightens the load so instead of a list of python objects you get an "array of
data for n python_type objects" without the duplications of the python type for
every element.
I think maybe some more complete examples demonstrating how it is to be used
from both the Python and C would be good.
Cheers,
Ron
