When using winpcap capture the UDP packet, I always appear when the data rate of 30 MB/s problem of packet loss (my card is gigabit nics, between two computers with network cable directly connected), before use pcap_next () to capture the UDP packets, found that such inefficiencies, now want to use the dump to capture the packet capture, but the dump can only be stored data, including baotou and file header, I want to get rid of baotou in the storage time and file header, have what good method, furthermore, by modifying the source code of winpcap, recompile should is feasible, which a great god has his own modified to implement the function of the source code, can you give me the reference or library,
