Opening raw sockets in c is mad complicated yo. This library encapsulates the heavy lifting for non-weird drivers and returns you a socket that you can you can consume for a given interface name.
Since this is a clib library you can easily install it via:
clib install 4thel00z/libsniff
#include "../deps/libsniff/libsniff.h"
#include <stdio.h>
int main() {
int sock = libsniff_open_raw("wlan0mon");
if (sock == -1) {
fprintf(stderr, "something went wrong with libsniff_open_raw");
return sock;
}
// Use sock with recv and a buffer...
return 0;
