For most people, the easiest way to get wpcap working is:
// Find all network devices if (pcap_findalldevs(&alldevs, errbuf) == -1) fprintf(stderr, "Error finding devices: %s\n", errbuf); return 1; For most people, the easiest way to get
// Print device list for (pcap_if_t *d = alldevs; d != NULL; d = d->next) printf("%s\n", d->name); if (d->description) printf(" (%s)\n", d->description); For most people
pcap_freealldevs(alldevs); return 0;
