[Winpcap-users] WinPcap 3.1 beta 4 memory leak? crashes?

[Tom Brown]

Gianluca,

Thank you! That explains what we are seeing. How long is a few weeks? Two 
weeks? Three weeks? My manager would like you to know we are calling 
pcap_findalldevs() in a "mission critical" application. It's already been 
released to our customers and we are looking for an update soon. In the 
meantime, I can try using RegisterDeviceNotification(), as suggested in a 
previous post, to cut down on the memory leakage.

Thanks,
Tom
