Hi, I'm following a tutorial about 10 years old and I'm running into trouble compiling this source.
I found this on libpcap's website and cannot compile it. I'm running Windows 11 Pro Visual C++ 2022. The location for the C:\Windows\System32\Npcap .dll and I think this is the way to compile this. Any suggestions please I'm starting to learn socket programming.
