This is the first time I write to this list. I just read a post about thebehavior of function pcap_lookupdev().Now I wonder: what if I have two or more (2...N) Ethernet NICs installed in my computer and I want to retrieve the name of the second NIC to associateto a socket and start reading from it? Is there a way to achieve this using this function?
No.In newer versions of libpcap, however, there is, however, a way to find all the devices on which you can capture; you use pcap_findalldevs().
Choosing the appropriate adapter from the list pcap_findalldevs() returns is the job of the application using pcap_findalldevs() (because pcap_findalldevs() has no idea which adapter would be appropriate, as it doesn't know what criteria to use).
