Hmmm... the "find" function cannot detect that embedded within () I guess.
Thanks GV...
So do you have any idea how at this low level I could determine the packet
count so I could display it on my application screen? There is a byte count but
that is not the same...
Thanks,
Dennis

Subject: Re: [Winpcap-users] Anyone have current Packet32 source?
The code in the compiled DLL is the same as the one that we ship as a source
package (I'm the person who builds the packages). Remember that the same
sources generate different binaries, depending on the build configuration you
use (NT4, NT5x, NT6x).
The code you sent actually makes use of the Sync flag, here
Res = (BOOLEAN)DeviceIoControl(AdapterObject->hFile,
(Sync)?BIOCSENDPACKETSSYNC:BIOCSENDPACKETSNOSYNC,
(PCHAR)PacketBuff + TotBytesTransfered,
Size - TotBytesTransfered,
NULL,
0,
Have a nice day
GV
