DESCRIPTION
dns_name_packet is a low-level component of dns_name4, designed to sup‐
port asynchronous DNS lookups. It reads a DNS packet of length len from
buf, extracts the first PTR record from the answer section of the
packet, puts the result into out, and returns 0 or -1 the same way as
dns_name4.
