Ah. I'm not sure how the C++ library works in that sense, but if it
takes function pointers then you can do something else like:
Then in C#:
delegate void EventHandler(...);
Pass the delegate to the unmanaged code (make sure you keep a managed
reference to the delegate so it's not garbage collected) and then your
unmanaged code will in fact be calling into managed land when it uses
that function pointer.
