It puts the (first) domain name into out and returns 0. If the relevant in-addr.arpa domain does not exist in DNS, or has no PTR records, out will be empty. If dns_name4 has trouble with the DNS lookup or runs out of memory, it returns -1, setting errno appropriately. It may or may not change out.SEE ALSOdns_name_packet(3), dns_name4_domain(3), dns_name6(3), dns_ip4(3) dns_name4(3)
