Hi,
I'm just beginner, new winpcap user.
Here is something working :
memcpy(ethernet, packet, sizeof (struct ethernet_header));
BTW, be careful about how packed are your datas, for exemple
struct ex
{
char c;
int i;
};
can be 8 bits wide instead of 5. Look at how to use
#pragma pack(1) within visual studio.
In fact, you can do it with many ways. This one is quick but
dirty.
