Wireshark · Wireshark-dev: [Wireshark-dev] Get COL_INFO string?

["David Underhill" <dgu@xxxxxxxxxxxx>]

I have a dissector which is calling the Ethernet dissector on part of the packet.

This causes the dissector to re-label the protocol and COL_INFO fields with the sub-packets dissection.

Ideally,
what I'd like to do is prefix COL_INFO data to the stuff that gets set
after I call call_dissector.  It seems like one way to this is after I
call call_dissector, I could get the current string and then create a
new one with my text prefix to that string with snprintf. 
Unfortunately I don't seem to be able to find a method which tells me
what the COL_INFO is.

Any ideas?

Thanks,

~ David
