Roger, for the sake of my mental health, would you mind put a sample
that indeed works?

Wayne already answered to you that ffi_lib takes an array, multiple
invocations to append are not possible.

If you believe that could be improved, send a patch.

Also, when using functions, try put the indication to a true function,
which in the case of FindWindow, as discussed before, do not exist.
