Hello, While I was writing a network application, I was thinking that it would be nice to have a syscall that could "bind" two file descriptors, of any type (socket, file...), a bit like funopen() does in the libc. Having such a syscall in the kernel would allow to implement "zero-copy" wherever it is feasible. Then, sendfile() would just be a particular case of this syscall, where the input fd is a file and the output fd is a socket, and it could be rewritten using it. Do you think this makes sense and it would be useful to have ? Just my $0.02, Maxime -- Don't be fooled by cheap finnish imitations ; BSD is the One True Code Key fingerprint = F9B6 1D5A 4963 331C 88FC CA6A AB50 1EF2 8CBE 99D6 Public Key : http://www.epita.fr/~henrio_m/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-arch" in the body of the message
