that's because you are not calling the pcap_dumper function from within the pcap_loop callback.
your "my_callback" function simply prints out "Welcome".
 
Even if you are running on *nix, I suggest you to have a look at the samples included in the WinPcap developer's pack (examples-pcap folder).
 
Have a nice day

Subject: [Wireshark-dev] request help for packet capture using libpcap

Hello ,
 
I have been trying to write a small application using libpcap library.
Purpose is to capture some live network packets(say 100 packets) and store them in a file (pcap_savefile).
 
Please refer the attachment for the code.
 
As per my understanding the pcap_savefile should be in "pcap" format as this is the default file format for libpacp.
But when I pass this file to wireshark, it does not show any packet data.
Also the size of the pcap_savefile is just around 24 bytes for 100 packets.
So I was wondering whether the programm is actually capturing any network packet.
 
Could anyone please suggest how I can improve the programe and store the data in pcap format.
 
Thanks in advance.
 
Regards,
Atdev
