DESCRIPTION

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