       int dns_name_packet(stralloc* out,const char* buf,
                           unsigned int len);

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.
