Generally speaking, functions which have to be called by the OS have to be
of a different calling type than C++ memeber functions. No way to mix the
two, AFAIK.

Why not? Of course, you don't have the implicit "this" pointer.
But you should be able to explicitely pass any piece of data you want to
your C-type function, including a pointer to your class instance. This
should work for you - or am I missing anything?

Hope this helps,
