DESCRIPTION

       dns_name_packet  is  a  low-level component of dns_name4, designed to support 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.
