No, reads are assumed to be "side-effect" free (as far as the options
are concerned).

OK, got it.

Nope, not at this point. Printing messages wouldn't be hard to do,
but dialog boxes are a bit trickier because sometimes there is no user
to dialog with. What exactly did you have in mind?
As a general comment, I fully expect that we'll have to make some
adjustments to the SANE API to better support digital cameras. I'd
suggest that, for now, you hack around problems you encounter as your
progresses. Then, once we're confident we understand what's needed to
support cameras well, we can then add the missing stuff to the API.
Sounds reasonable?
