Wireshark-dev: [Wireshark-dev] Running a function only on first run

Hello,

I'm trying to have Wireshark maintain a list of certain information
from packets as it receives them (using a GHashTable or a GSList, not
sure which yet). The problem I am facing is that the code in my
dissection routine that does this gets run once on each packet as they
are analyzed, but also every time I click on a packet. I understand
this is how Wireshark works, but I was wondering if there was some way
of telling if this is a "first run" analysis or a second-visiting of
the same packet, without maintaining my own variables to keep track of
this for each packet. Does this make sense?

Thanks,
Jeremy
