Unless the code in that project calls pcap_freealldevs() on the list it gets back from pcap_findalldevs_ex(), that's a leak. Presumably, if you're using that code, it's only calling pcap_findalldevs_ex() once, so it's not a *continuing* leak, however. > and I noticed that when I looked at my app in task manager it was increasing > its memory usage like crazy.

How do you know that it's WinPcap, not your application? WinPcap isn't supposed to keep allocating memory while you're capturing traffic, no matter *how* it's configured. Could you send us your code, so we can see whether there's a leak in it? _______________________________________________ Winpcap-users mailing list [email protected] https://www.winpcap.org/mailman/listinfo/winpcap-users
