[Winpcap-users] pcap_findalldevs_ex hangs inside java process

[Mark Bednarczyk]

 Mani,
  we use pcap_findalldevs_ex in our java project and we have no problem
within java VM. There are thousands of users using our project and it has
never come up as a problem. Our internal tests with findalldev_ex work as
well. Its an open source project, so you are welcome to take a look at the
source and how we use it.

http://jnetpcap.com

here is the link to the relavent C source file that implements the
<http://jnetpcap.svn.sourceforge.net/viewvc/jnetpcap/jnetpcap/trunk/src/c/wi
npcap_ext.cpp?view=markup> findalldevs_ex as a java wrapper. The
findalldevs_ex code starts around line 750.

Cheers,
mark...
