Thanks Helmut. Could the filter be positioned on the Driver layer? If could,
how to write the filter string and then pcap_setfilter(...)?

I just filter out unwanted packets (in your case, packets sent by your app) by
comparing ether.source with the MAC address of the bound adapter.

Hi experts,
There is a problem about use pcap_next_ex(...) to receive packet in Windows
XP SP3. This function will be unexpected to receive the packet sent by the
function pcap_sendpacket(...) in the same port. And when I use
pcap_setdirection(m_pcapHandle, PCAP_D_IN) to set it, it will return -1, the
error info is "Setting direction is not implemented on this platform". How
could I implement the functionality that the pcap_next_ex(...) don't receive
packet sent by pcap_sendpacket? Any help from you will be highly appreciated.
Thanks!
BR.
Sam
