Hello,
I am developping an application that uses multiple threaded
environnement on Windows XP.
One of these threads opens a network interface to count the number of
packets per second and compute statistics.
This architecture works fine for a real network interface (ie realteck,
3 com, ...) but fails with the first interface (Adapter for generic
dialup and VPN capture).
I have made a little change on my code to use the same thread than my
application.
The result is good. My application works without deadlok.
If I resume :
- Multithreaded :
main thread Statistic thread
-> Do something... -> pcap_open_live()
on the first interface (Adapter for generic dialup and VPN capture)
=> Result is a deadlock in the pcap_open_live() function. The function
is blocked.
- Single threaded :
main thread
-> pcap_open_live() on the first interface.
=> Result is an handle on the file openned (no deadlock detected).
I have tried this solution only on WinPcap 4.1.1. I don't know if this
problem appears in another version of WinPcap.
Can you help me ?
Thank you in adavance,
Cyril
