associate
to 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).
