In article <mit.lcs.mail.freebsd-arch/Pine.NEB.3.96L.1010301084659.65459C-100000@fledge.watson.org> you write: >There are, unfortunately, a few apps that make use of the inode >number returned by stat -- generally to try and detect hard links (I >think tar does this). As I have pointed out before, it is a requirement of POSIX that distinct files have distinct (device, inode) pairs. The individual st_dev and st_ino values are not required to have any particular meaning except when used together in this way. (So, it's possible to treat the pair of members as a single 64-bit quantity, should that be desired, provided that uniqueness can be guaranteed.) -GAWollman -- Garrett A.
