Thanks for the explanation.
1. << The result of a packet dissection is thrown away as soon as the packet has been read and presented, so if you 'click' on a new packet the dissection has to be redone.>> "Thrown away" means it's not stored anywhere. Am I right? If yes, why is it thrown away? And also, few things are done only once using "flags.visited == FALSE", why then this variable is used, if the previous results are not stored, then everything has to be redone. 1. << Not sure what you are referring to here >> In packet-rlc.c in epan/dissectors, duplicity of RLC frames is checked, should that be done everytime? ________________________________ From: wireshark-dev-boun...@wireshark.org [mailto:wireshark-dev-boun...@wireshark.org] On Behalf Of Anders Broman Sent: Friday, January 10, 2014 2:53 PM To: Developer support list for Wireshark Subject: Re: [Wireshark-dev] Siginificance of pinfo->fd->flags.visited From: wireshark-dev-boun...@wireshark.org [mailto:wireshark-dev-boun...@wireshark.org] On Behalf Of Vishnu Bhatt Sent: den 10 januari 2014 08:59 To: wireshark-dev@wireshark.org Subject: [Wireshark-dev] Siginificance of pinfo->fd->flags.visited >Hello all, > >Can anyone please explain me the significance of pinfo->fd->flags.visited.
