[Pyrex] Re: C-methods in extension types

[Lenard Lindstrom]

Sorry, I missed the part about calling est_mtdb_get_doc outside 
Document. As long as you cdef a reference to Document you can access 
its attributes and C methods. I assume set_doc looks like this:

    cdef set_doc(self, ESTDOC *doc):
        self.doc = doc

Then:

cdef Document New_Doc    # Now the set_doc C method is callable
New_Doc=Document(Void=True)
New_Doc.set_doc(doc)
return New_Doc
