Hello,

Trying to create a project that access a pcap file and prints ETH add, IP add and TCP/UDP. For a reason when I'm doing...

int ether_type = ((int)(pkt_pointer[12]) << 8) | (int)pkt_pointer[13];

		

		if(ether_type == ETHERTYPE_IP)

			offset = 14;

		else 

			offset = ?;

		

		pkt_pointer += offset;

Getting BUS ERROR. I know that error happening on the last line, but can't solve it. Any idea? Also, how many will be the offset in the else statement? Else refer to ETHETYPE_ARP.

Thank you

Where are you getting this BUS ERROR thing from?

What does the question mark ('?') on line 6 mean?

Good catch, I didn't even see that. That shouldn't even compile.
