Wireshark · Wireshark-dev: [Wireshark-dev] looking into dissection information

[Ravid Gabbay <ravid@xxxxxxxxxxxx>]

Hello,
I'm building a dissector that among other things call other dissectors 
like the wlan dissector.
I want to be able within my dissector to view what has been dissected by 
the wlan disscetor (without changing it offcourse, and without repeating 
the wlan dissection).
for example, I want to be able to know if the dissected packet is a 
beacon (which as a user I'd do wlan.fc.type_subtype == 0x08, to see if 
it's a beacon)

How can I do that?
is there an example I can use?

Thanks
Ravid
