:> If it's a regular file [...] : :BZZZT! Wrong, but thanks for playing. (We are talking devices here) : :-- :Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 Well, most devices don't give a damn about the file offset supplied in the UIO from the file descriptor, so if it isn't a regular file why would you care?
