Thanks for the reply. However guess, its better to restate my problem, so that i can make you people clear about my query.
I am using some 3 NICS ( network interface cards), which together get me 10 ports. 2 NICs are are from D-Link NIC cards which have 4 ports each in them, and another is NETGEAR NIC, which has 2 ports in it. with the help of pcap_findalldevs() , i can obtain the list of all ports , along with details of NIC cards, their MAC_ addresses and others. But my question is , pcap_findalldevs( ), gives me list of all 10 ports i am using, assume i use a cross-cable and connect any 2 ports to form a loopback condition,then is their any function in wpcap, which tells me which 2 ports are in loopback state among the 10 ports i am using. or any other function is their apart from wpcap, which helps me to do this. please help me to figure out this problem.
