Hi Alex,
thanks for your tips ... and patience!
My lack of experience with C, Pointers and low level programming clearly
shows in my questions, and most real world libraries of 'native' wrappers I
find don't really implement complex C signatures, so I have to experiment
myself.
I'll try to digest your hints and do some more experimentation over the
weekend.
Luckily, If I manage to wrap one such C function, I can reuse that
understanding for many others ....
Cheers
Thorsten
