NAME
       dns_name_packet - extract names from DNS answer packet

SYNTAX
       #include <dns.h>

       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.
