So I'm trying to work out a way to have socket passing using DuplicateHandle. Unfortunately I don't think that sendmsg works correctly.
I use socketpair to create a pair of connected Unix Domain sockets. Then I fork. Then I create a socket which I want to pass to the child. But when I call sendmsg on the original socketpair thing it returns -1, a Bad Address. I don't set msg_name in the msghdr because the socket is already connected. So I went into the sources and sure enough sendmsg is implemented by calling sendto using the msg_name that's being passed, and since message name is null the call dies. I know that calling sendmsg, on a socketpair after a fork, with no name works on Unix. Is there any way around this?
