pcap_t *handle = pcap_open_live("\\Device\\NPF_{GUID}", 65536, 1, 1000, errbuf); pcap_compile(handle, &fp, "tcp", 0, PCAP_NETMASK_UNKNOWN); pcap_setfilter(handle, &fp); pcap_loop(handle, 10, packet_handler, NULL); Your packet_handler will see raw Ethernet, IP, and TCP headers.

Download the latest stable WinPcap from the official site (or use the Npcap fork for modern Windows). Run the installer. Check “Automatically start the WinPcap driver at boot.” Reboot? Usually not needed, but don’t skip it if something feels off. jumpstart winpcap

#include <pcap.h> int main() { pcap_if_t *alldevs; char errbuf[PCAP_ERRBUF_SIZE]; pcap_t *handle = pcap_open_live("\\Device\\NPF_{GUID}"

Here’s a short, punchy piece on Jumpstart WinPcap — part tutorial teaser, part conceptual intro. Your packet_handler will see raw Ethernet

Now go capture something.
