If I read the Windows unit sources correctly, INVALID_HANDLE_VALUE = -1
too. However, I believe that you might consider returning UnusedHandle
constant defined in System unit for all the platforms (that's -1 for at
least most of them anyway, but I believe that it may be still better from
portability point of view to refer to it using this constant).
I cannot rely on what the actual value of INVALID_HANDLE_VALUE really is
as it could in theory change. But nevertheless your suggestion to return
the UnusedHandle constant, once I locate it :), is very logical.
