NAME
dns_ip4_packet - extract IPv4 address from DNS answer packet
SYNTAX

,
unsigned int

);
DESCRIPTION
dns_ip4_packet is a low-level component of dns_ip4, designed to support asynchronous DNS lookups. It reads a DNS packet of length len from buf , extracts IP addresses from the answer section of the packet, puts the addresses into out , and returns 0 or -1 the same way as dns_ip4.
