The LUA API lacks an equivalent to tvb_get_stringz().
This could be worked-around with the following LUA code, but it would be nice
to have it in the API.
local function tvb_get_stringz(tvb, offset)
local len = 0
while tvb(offset + len, 1):uint() ~= 0 do
len = len + 1
end
len = len + 1;
return tvb(offset, len), offset + len
end
