"Time since first packet" is straightforward to calculate if, for example, the time stamp of the first packet is stored in the capture_file structure for the file. "Time since previous captured packet" is straightforward to calculate given the current packet's frame_data structure and the previous packet's frame_data structure (which is straightforward to find if you know the current packet's frame number - if the frame number is 1 "time since previous captured packet" is your choice of 0 or "leave it blank because it's inapplicable" and if it's > 1 then it's the value for frame N-1). "Time since previous displayed packet" is a bit more work - you have to scan backwards through frames until you either hit one with flags.passed_dfilter set or run out of frames (in which case the answer is either 0 or "leave it blank because it's inapplicable"). ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <[email protected]> Archives: http://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://wireshark.org/mailman/options/wireshark-dev mailto:[email protected]?subject=unsubscribe
