This is the output:
getaddrinfo AF_UNSPEC/SOCK_STREAM/AI_ADDRCONFIG failed
so, yes: hints.ai_flags = AI_ADDRCONFIG; makes getaddrinfo fail.
Just so I can understand the precise nuances of this, can you post
the
output of:
wget http://people.apache.org/~jorton/gai.c
make gai
./gai ::1
./gai ::1 null inet6
./gai -a ::1
./gai -a ::1 null inet6
Ubuntu 7.04 (no ipv6 addresses -- other then loopback -- configured):
[EMAIL PROTECTED]:~/gai$ make gai
cc gai.c -o gai
[EMAIL PROTECTED]:~/gai$ ./gai ::1
getaddrinfo("::1", NULL, {.family=AF_UNSPEC, .hints=0}) = 0:

Same machine, now with -n:
