<DIV><FONT size=2>Benjamin,</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>what do you mean exactly by "stopping the capture
correctly"?</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>pcap_next_ex is simpluy an API reading packets from a WinPcap
adapter (like a read on a socket or file), so there's nothing so special to
do.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>In general if you want to close your app cleanly (well, every
application!) when Ctrl-C is hit, you should register a handler for the Ctrl-C
"signal" and in this handler set some flag that tells the main thread (i.e. the
one running main()) to stop looping over pcap_next_ex()</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>This is just some pseudocode (I haven't looked at the
documentation, so the prototype of the handler is probably
wrong):</FONT></DIV>

<DIV class=RTE>I want to know if it is possible to stop the capture
"correctly" when I use "pcap_next_ex" to capture packets.</DIV>
<DIV class=RTE>"Correctly" means when I enter Ctr+C for exemple!</DIV>

<DIV class=RTE>Thanks you</DIV>
