Thank you. Now I have noticed "data" is a pointer

I add "printf("%s\n",(pinfo->src).data)"

For almost all address types, including IPv4 and IPv6 addresses, the data field does *NOT* point to a text string.  Wireshark deals with binary packet data; it does not turn everything into nice easy-to-print strings.  If you want to get the string corresponding to the address, use Wireshark's ip_to_str() routine.

I have solve this problem about get ip address.However there is another question,When I print the ip address I notice there are two ip addresses I get.I think this because there are two kinds of packet in or out.So how to judge a packet is in or out ?
