I don't believe the application code deals with this,
it just works in terms of IP addresses, not interfaces.
The OS maps the IP addresses to interfaces.
If you try to open an IP address that the OS believes
is on eth0, you'll get an eth0 socket.
If you try to open an IP address that the OS believes
is on eth1, you'll get an eth1 socket.
Try
ifup eth0 192.168.1.1
and open a socket on 192.168.1.2,
and then
ifdown eth0
ifup eth1 192.168.1.1
and try again. Your packets should head for eth0 in the
first case, and then eth1 in the second case.
Note that I haven't actually done this, but its a reasonable
guess :)
Cheers,
Dave
