I'm trying to be sure how to do computed offsets larger than 2G. I looked at the source for dd, and it multiplies and unsigned long with a size_t and puts the result in off_t (which is the new wide type if things are compiled with the new largefile symbols). I would like to have some idea why this works though. Examining the headers, off64_t looks like it is really a structure consisting of a single array of two long integers, is the compiler responsible for making this multiplication make sense, or what?
