Oh, thanks.

I have done two tests, and I think savedump doesnt miss any packets. What can be the problem then? Maybe parameters in pcap functions or buffering?

What do you mean by "quite unreadable"?

savedump creates a pcap-compatible file that can be opened with wireshark 
(it's not a text file, it's pcap file i.e. binary).

I have tried it and the content of the capture file (which I have given the 
name of 'dump.txt') is quite unreadable.

Out of curiosity, does the sample in the WinPcap developer's pack named
wpdpack\Examples-pcap\savedump lose packets as well?

Hi

I am implementing a packet sniffer with VS. I posted some time ago problems
with losing packets, and someone here suggested me that it could be a
problem between disk access and NIC speed.

I have done some research, and it seems this doesn't happen to Wireshark
because of the use of a ring buffer. Can someone tell me which files (apart
from ringbuffer.c) are involved in Wireshark avoiding packet loss? Can I use
any configuration of Winpcap function parameters for losing less packets?

Thanks in advance
