how about
fzero(int fd, off_t off, size_t len)
which zeros the blocks and if it can creates a holey file?
However, that's not what Bob wants, he wants to remove commercials from recorded TV. So what he wants is
fdelete(int fd, off_t off, size_t len)
which has the semantics of shifting the rest of the file backwards to "off".
The main problem with this is if the off/len are not block aligned. If they are, then this is just block twiddling, if they aren't, then this is a file rewrite anyway. -- --- Larry McVoy lm at bitmover.com http://www.bitmover.com/lm - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
