So I'd say the originally reported behaviour is "works as designed", and you'll have to code some other way if you want different results. In other words, if it wasn't meant to be very similar to regular snprintf, it would have been called something different. Using the "printf" family of names infers it acts like printf and friends every where else. 'tis a feature, not a bug. B-) -- A big old stinking pile of genius that no one wants coz there are too many silver coated monkeys in the world.
