No, it isn't specific to wireshark. I only needed this:

function extract_com.packet()

    local values = { ctxId() }
    -- {} is a table constructor, so values is a table

    -- then you can iterate over the entries in your "values" table
    for i,value in ipairs(values) do
        
        print (i, value)
        
        test = tostring(value)
        print (test)
    end

    -- You can even return all values if you want using unpack:
    return unpack(values)
end

Thanks
Joseph

This is a wireshark specific question. There is no generoc way to access
internals of userdata (lua doesn't know what's in a userdata, its
untyped memory from its point of view), you have to use the functions
that the implementor of the wireshark provided to work with that
userdata.
