nice! very nice...

I never figured out how to create a typemap for a struct so that I could use
the struct as an argument in a call to a function in a C library. Note... a
struct not a pointer to a struct. There are a couple functions in the
Win32API which actually take things like a POINT or a RECT as an argument
and not just a pointer to it. I've worked around this by passing each member
of the struct as separate arguments. But it always bugged me that I couldn't
find a way to actually pass the struct itself as an argument.
