Till,

Sorry for the previous reply - I read these messages out of order.

I'm really just suggesting you add a small additional C++ source file to
your project in which you do all your PJ accessing and have it only include
the bare minimum of stuff.

Well, it is certainly available.

Possibly, though potentially there are a lot of fields you might want access
to.

Best regards.
