We might also want to pre-emptively offer iovs instead of offsets, because that's the very first thing that's going to be requested after people prototype having to iterate calling sendfile() for each contiguous copy region.Indeed, I was about to propose that exactly. So that would be psendfilev. I don't think psendfile is useful, and can be easily provided at the libc level. Paolo
