I would split the wrapping in layers, the lowest layer is a one on one exposure of the library with your wrapper, I would rather avoid ctypes for performance reasons, however if performance is not a concern ctypes is excellent and broadly available.

The next layer is purely there to make the lower layer pythonic, i.e. apply namespaces, automatic handling of memory, PEP8 naming convetions, etc. etc.
just what you would expect from a modern pure python module

The next layer, if you want to, contains tools that are often used in that concept, think in the line of design patterns.
