are in the current version of WinPcap. WinPcap 2.2? I don't have the foggiest
idea. They probably were, but also consider that a large number of bugs were
fixed since WinPcap 2.2 was released. For sure, if you are using a
multiprocessor/multicore machine, WinPcap 2.2 will not work properly there...</span><span

<p class=MsoNormal>Hi,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’m trying to debug some old code written around WinPcap
2.2. I’d rather not update to a newer version if at all possible.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The problem is that pcap_next() sometimes returns a non-NULL
packet pointer, but the returned packet header length is 0. Repeated
calls to pcap_next() return the same packet pointer with a header length of 0
and the timestamp no longer increments.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The capture code runs in its own thread and appears
correct. However, I do notice that a separate thread is used to call
pcap_sendpacket() with the same pcap descriptor. Are these calls thread
safe?<o:p></o:p></p>
<p class=MsoNormal> <o:p></o:p></p>
<p class=MsoNormal>I appreciate any help I can get.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks,<o:p></o:p></p>
<p class=MsoNormal>Rick<o:p></o:p></p>
