You can already do the last one with libarchive;
just register an output function that counts the
bytes but doesn't do anything. Done.
"Fast and exact" is simply not possible in general,
so I don't think I would bother with that option
at all.
Incorporating some sort of estimator into the API does
sound like a good idea. I'll have to think about it
some to see if I can figure out a good way to do that.
Thanks for the feedback,
Tim
