What platforms have sin_len in the generic sockaddr structure?  The one I've 
always seen is sa_len, and that's consistent with sa_family in terms of field 
name prefixes.

sockaddr         -> sa_
sockaddr_in      -> sin_
sockaddr_in6     -> sin6_
sockaddr_storage -> ss_

I suspect you'd do fine if you ditched the test for sockaddr.sin_len and tested 
either sockaddr_in.sin_len or sockaddr.sa_len.  (And I'd expect an OS to be 
consistent as to whether the _len field exists for each of the various socket 
address structures.)

At first glance, the IPv6 flavor of the code looks okay on this score...
