Hi Carlos,

You can write a "wrapper" to make C functions look like Python functions.
There' s a good utility called SWIG that makes wrapper writing fairly
easy:

    http://www.swig.org/

It usually involves telling SWIG what the function interface looks like.

accessible to Python.


If you're curious about how all this actually works, you can take a look
at the Extending and Embedding Document:

If you have more questions, please feel free to ask.  Good luck!
