[Winpcap-users] basic_dump example

The reason behind this requirement is that in order to list the adapters we need to
1. start the underlying kernel driver if it's not already running and
2. communicate with the driver to get some information from each adapter.

Hope it helps

  The line:
 pcap_findalldevs_ex(PCAP_SRC_IF_STRING, NULL, &alldevs, errbuf)
returns -1 and the app then exits with
 fprintf(stderr,"Error in pcap_findalldevs: %s\n", errbuf);
What's the full message that it prints?  (I.e., what's in errbuf?

  My mistake, I didn't run the app as administrator. I'm a little surprised though that it's not even possible to enumerate the devices without running the app as administrator.
