Yep; the C library whose API I'm using uses macros to cast things to
the right structure, and (similar to Cython), as I already _have_ the
code, I wasn't particularly interested in working out how to convert
things like:

        LASSO_SAMLP2_NAME_ID_POLICY(LASSO_SAMLP2_AUTHN_REQUEST(
                LASSO_PROFILE(login)->request)->NameIDPolicy
            )->Format = strdup(LASSO_SAML2_NAME_IDENTIFIER_FORMAT_PERSISTENT);

into ctypes compatible syntax, when I can simply adapt the working C
code to Python. :)

Plus, there is the library static initialisation to manage, the issues
of distributing the C libraries if I do a C wrapper to call from
ctypes. This way, it can be distributed from our devpi very easily.
