Re: Bug#752237: libc0.3: send() asked to transmit 0 chars still triggers recv() on Hurd

[Roland McGrath]

I'm inclined to say libc is not the right place to fix this.  If the user
says write/send 0, what that means should be up to the io server to
decide--even if all the servers we have today are intending to implement
the same POSIX semantics.
