[Winpcap-users] Regarding sniffing on multiple interfaces.

[Mygapula, Sudheer IN BLR SISL]

Thanks for the fast response..

Another questing...if I am actively sniffing the packet on adapter and suddenly the adaper is disabled or some problem with Network adapter.

Then how I will be notified ? So that I can stop sniffing on such adapter.

Packets accumulate in the kernel buffer of WinPcap until the buffer is full.
When the buffer gets full and you do not process the packets with pcap_next_ex or similar, all the subsequent packets are dropped.

Let me know if this answers your question.

Have a nice day
