unsigned int len);
dns_ip6_packet is a low-level component of dns_ip6, designed to support asynchronous DNS lookups. It reads a DNS packet of length len from buf, extracts IPv4 and IPv6 addresses from the answer section of the packet, puts the addresses into out, and returns 0 or -1 the same way as dns_ip6.
