[lwip-devel] Why pcap_findalldevs_ex()?

[Gisle Vanem]

In contrib/ports/win32/pcap_helper.c there is a call to pcap_findalldevs_ex().
What's the advantage of this over the more normal pcap_findalldevs()?

 char source[] = "rpcap://";
 int index = 0;
...

  if (pcap_findalldevs_ex(source, NULL, &alldevs, errbuf) == -1) {
     printf("Error in pcap_findalldevs: %s\n", errbuf);
     return -1;
  }

Can we please use the simpler pcap_findalldevs()? There is a lot of
problem elsewhere with this function. E.g. look at the Wireshark
developers mailing-list; some distros of libpcap seems to require 
PCAP_REMOTE be defined when building or using this function in
libpcap.
