pyHANDLE is something of a special case, I suspect, since I can't
think of a situation in which you're going to create it yourself:
it'll always be returned from a call to, CreateFile etc. Once you
have the handle, the documentation which I assume you've seen for
the pyHANDLE object itself applies, although there's not much one
can usefully do with it except close it and refer to its [handle]
property which is the real Win32 Handle.

Are there other classes you can't find out about? If so, what are
they? I find the ActiveState CHM docs to be pretty good on the
whole. And, in case you haven't already looked, the Mark Hammond &
Andy Robinson book "Python Programming on Win32" is a must-have.
(At least via Safari: http://safari.oreilly.com/1565926218).

Ultimately, search the source, but that needs more time
than most people have when they're in a hurry!

Yes, I saw your post on c.l.py earlier. No experience of my own,
I'm afraid, and I don't have time to experiment just at the moment.
Could you post some useful code? Ideally using Python at both ends
of the pipe, but at least showing the sequence of events from the
Python perspective?
