Hello,
I would like to ask you a question about pcap library. I try to use function
pcap_loop on a loopback device. My callback function is quite simple, it just
gets sequence field from ICMP and prints it. When I run my program and start
to ping the lo device the program produces strange output. My callback
function is called four time for every packet arrived. It seems to me that
the pcap_loop function is calling callback as fast as it can and in my case
it is four time before new packet arrives. What's more, i tried to slow down
my callback function by using a loop. For 65535 empty iterations there was
the same effect but for 65536 iterations my program catches only the first
packet and then starts to behave like there was no more traffic. What is the
problem? It is very important to me to synchronize this because I have to
catch EVERY packet and then decide if to drop it or not.
thanks for quick response
