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
