WinPcap does not provide any information regarding the direction of the packet. 
You will need to get this information by looking at stuff like the source and 
destination MAC address of the packet.

Subject: [Winpcap-users] how to determine input and output packet?


Hi all

 

I would like to know if the packet received from pcap_next_ex() is an input 
packet or an output one?

 

Thanks for your help.

 

Germain
