[Winpcap-users] how to de-register handler

[Gianluca Varenni]

The packet is not actually registered inside the library. When you call pcap_loop (or pcap_dispatch), pcap_loop blocks and internally uses the packet handler you provided to hand off packets to your application. As soon as pcap_loop/pcap_dispatch returns (for a reason or another), the packet handler that you provided is no longer used by the WinPcap library (it's NOT stored internally).

My humble suggestion is to use pcap_next_ex instead of pcap_loop/dispatch. It provides the same functionality, but it's IMHO much easier to understand and use.

Have a nice day

  Hi all,

   

  I register my specific packet handler using the API "packet_loop" during the init of my app. When I have to terminate I try "pcap_breakloop", but it doesn't seem to de-register the handler from the Winpcap lib.

   

  Any clues?

   

  TIA
