[Winpcap-users] Old WinPcap Question

[Rick Anthony]

At this point, it might make sense for me to update to a current version
before I troubleshoot more.

Thanks for response,
Rick

They 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...

 

Have a nice day

	Hi,

	 

	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.

	 

	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.

	 

	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?

	 

	I appreciate any help I can get.

	 

	Thanks,

	Rick
