[Winpcap-users] Filters in a multi-threading application

[Marcel van Lieshout]

Hello,

I'm working on an application where (through winpcap) packets are received 
and sent. I have created two threads: one will only receive packets, the 
other will only send packets. Both threads have their own handle to the same 
adapter.

Because the sender never receives packets, it never calls pcap_next (or one 
of the other packet retrieving functions). Only pcap_sendpacket() is used. 
Which filter should I set to let the driver know about this? I was thinking 
of something a filter like "len <= 1". Will this work? Sending packets 
should not be limited by the filter in any way.

Thank you!

Marcel
