If you have WinPcap 3.1, it doesn't - it retrieves them using 
pcap_findalldevs().

If *you're* using WinPcap 3.1, *you* shouldn't be using 
pcap_lookupdev(), either - *you* should be using pcap_findalldevs() or 
pcap_findalldevs_ex().

If you're using a version of WinPcap earlier than the 3.1 release (if 
you're using one of the alpha or beta versions of 3.1, you're using a 
version earlier than the 3.1 release), you should stop using whatever 
you're using, and start using WinPcap 3.1 - it's the only version the 
WinPcap developers support, and it fixes a bunch of bugs and adds 
additional capabilities.

That sounds as if you're using WinPcap 3.1.  Stop using 
pcap_lookupdev(), and start using pcap_findalldevs() or 
pcap_findalldevs_ex():
