[Winpcap-users] How to save packets to a file?

[He Zhiyu]

Hello,
I'm writing a sniffer for my graduation project(protocol analyzer),I have 
finished most functions of it.I captured packets and created a dynamic list 
to save all the packets in the buffer.Every node of the list contains a 
struct pcap_pkthdr *header and a u_char *pkt_data.I have a problem.How to 
save the packets in the buffer to a file,and read packets from the dump 
file? (I'm not able to use pcap_dump to do this,because pcap_dump_open 
needs a parameter(pcap_t *p) from pcap_open,but I should save the packets 
from the buffer to the file,not from the adapter to the file!)
Thanks a lot

Best regards
