If you download the Subdivision Surface Suite at:

You can find code that will help you.

Although the code I have at the above location doesn't support sharp
edges, you might want to do so.  It requires maintaining the state of
each edge, and the calculations get a bit more complicated, but
allows much more flexibility in the models you can support.
