How to find scope_id for an interface?

[Grant Edwards <grant.b.edwards@xxxxxxxxx>]

I'm trying to figure out how to connect to an IPv6 link-local address,
but I don't know what the value of sin_scope_id is supposed to be for 
the interface in question.  I took a guess that it was a small integer
(I only have two interfaces, including the local interface), but
nothing I've tried works.

How do I find the scope_id for a my Ethernet interface?
