Unfortunately this type of use of pointers is not going to work. You
are most likely going to have to wrap this particular struct up in a
class and deal with the pointers in a similar way to a previous post
( )

What you could do is make the wrapper class (as described above) for
the void pointer look like a python file object by providing
read/write methods. The union will also require access functions
because of the const char * type, though this is usually easily dealt
with by using an STL string.
