Apologies Bill - I missed this question.
Yes, I think this is safe, the index value must always be > 0 since
if_nametoindex() returns zero on error thus that can't be a valid index.
https://tools.ietf.org/html/rfc3493#section-4.1
BTW I didn't test on Windows so I hope the code works OK there too, it
looked like the standard sockets APIs were available.
If there is some Windows equivalent to "lo" on Linux then you could set:
#define TEST_ZONE_NAME ..
in test/testsock.c to as I did for #ifdef __linux__?
