I don't really understand what you mean, but I think we're sort of
talking about the same kind of thing?  In my example code a dbus int32
would map to a SANE_Int, a dbus string would map to a SANE string, and
a dbus boolean would map to a SANE_Bool.

Glad you agree. :)

Great job!  Thanks for doing all that, I'll check it out on my box.
