<DIV><FONT size=2>There is a machine, It send packets to my application ,
</FONT><FONT size=2>and the speed is fixed </FONT></DIV>
<DIV><FONT size=2>(about 200000 packets/per second = 0.000005 second for a
packet),</FONT></DIV>
<DIV><FONT size=2>the packet include some informations, my application need the
informations to do realtime control.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>my application need 0.0001 second (0.1 ms) to finish a control
loop,</FONT></DIV>
<DIV><FONT size=2>when the application doing control, it need
"current" information.</FONT></DIV>
<DIV><FONT size=2>but because the buffer, I always got the oldest information in
buffer,</FONT></DIV>
<DIV><FONT size=2>so i can't do the realtime control.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Does any function can clear buffer?</FONT></DIV>
<DIV><FONT size=2>or decrease the buffer size ?</FONT></DIV>
<DIV><FONT size=2>or stop capture packet for awhile ( let the incoming packets
drops immediacy, don't fill into buffer )?</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>another question, how large is the buffer size?</FONT></DIV>

<DIV><FONT face=Arial size=2>I don't think there is a way to get to the front
of the queue to get the latest packet. You have to sequentially read
through the queue.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Can you explain what your application is
doing? When you say you want the newest packet, what does that mean
(i.e. each packet received is the newest packet at that moment in
time)?</FONT></DIV>
