                         unsigned int len);

DESCRIPTION
       dns_mx_packet is a low-level component of dns_mx, designed to support
       asynchronous DNS lookups. It reads a DNS packet of length len from buf,
       extracts the MX records from the answer section of the packet, puts the
       result into out, and returns 0 or -1 the same way as dns_mx.
