[Winpcap-users] pcap_findalldevs Hangs when called in Windows service

OK, excuse the blatant ignorance of my question, but I am just curious.

Since pcap_findalldevs_ex(), IMO, is very seldom called, why are you
using sub-threads?

IOW, one call and you have your list and then can use that list for a
determinant period of time.  If changes occur you can just call the
function again manually.

If you can enlighten me I would appreciate it.
