The library function io.read effectively returns a string. So you were
right to try lua_checklstring.
So now, the error message was probably because the data was not the
first argument to the function.
Did you use something like object:method(binary_data) ? In that case
(with a colon in the call), the first argument will be `object` and
the second is `binary_data`.
