No, it just calls connect on the target ip address, and relies on the
kernel to select an appropriate src address and interface.

Hmm. Adding an interface option to specify an ip address, and using
bind(2) to bind that as the local address of the socket before
connecting, should be straightforward.

Not sure how to deal with interface identifiers, though. How should that
work? I'm aware of the SO_BINDTODEVICE setsockopt, but I'm not sure
that's what you are asking for.
