Pass a reference to the type.  So, for instance, if it's to be a list,
you do something like this:

if (!PyArg_ParseTuple (args, "sO!", &sequence, &PyList_Type, &offsets))

The different type arguments are in the C API manual.  E.g., PyList_Type
is in http://python.org/doc/current/api/listObjects.html
