I have a dissector that needs the capture file name at the time my dissector's
init function is called. I attempt to get the name with
plugin_if_get_ws_info(...), not an unreasonable request I think you'll agree,
but unfortunately the filename comes back as a NULL pointer.
I've traced through the code and this is what happens:
* We pass through the MainWindow signal and slot stuff and eventually call
cf_open(...) in file.c with the filename as one of the parameters
* cf_open(...) opens the file to test the validity of the filename and then
closes with cf_close(cf)
* cf_close(cf) frees the memory holding the filename and NULLs the filename
pointer in the cf structure
* cf_open then creates a new epan session with ws_epan_new(cf)
* ws_epan_new(cf) calls epan_new() which calls init_dissection() and this
is where eventually my dissector's init function gets called
* My dissector calls plugin_if_get_ws_info(...) which attempts to get the
filename info from the cf structure, which due to the above returns a NULL
filename pointer
* Eventually we return back to cf_open(...) and a little later we set up
the file name in the cf structure - all too late for my dissector's init
function
So my questions are:
* Can I raise this as a bug?
* If not, would a solution that made the filename available to
plugin_if_get_ws_info(...) at init time be accepted?
* What would be an acceptable solution?
Thanks and regards...Paul
