but how to get the location (called offset, right?) value? since I need to reach to the last byte of the packet
Offsets within the tvbuff containing your packet start at 0, so if your packet is N bytes long, the offset of the last byte of the packet is N-1. Subtract 1 from the result of tvb_reported_length(); that's the offset to use. ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev () wireshark org> Archives: http://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-request () wireshark org?subject=unsubscribe
