[Winpcap-users] Anyone have current Packet32 source?

[Dennis Drew]

GV,
When one passes a PacketBuf with thousands of packets, and that is passed to 
Res = (BOOLEAN)DeviceIoControl(AdapterObject->hFile,
The low level routine sends many of the packets auromatically. We only get to see TotBytesTransfered += BytesTransfered; which in my case is many hunreds of packets. Is there any way to get a caount back of how many were sent at the lower level?

Dennis

Can you elaborate on that? Which packets do you want to count?
 
Have a nice day
