[Winpcap-users] How can i get the new-est packet from buffer? HELPPLEASE~!

[David Chang]

Just keep calling pcap_next_ex.  It's a circular queue.  That is, new data is constantly being put in the queue.  Your application has to get the data out of the queue fast enough so that it doesn't drop packets.  If you don't take the data out of the queue fast enough (by calling pcap_next_ex), then it overwrites the oldest data.

  i have some data thansmite from another machine,
  it is very fast (about 200000 packets/per second),
  when i called function "pcap_next_ex",
  it always get the old data, i guess that's because the packets is fill into a buffer,
  if i need to get the new-est packet , 
  how should i do?

  Thanks.
