Subject: What good are File_Access's?

Message-ID: <6oo80p$m20$1@nnrp1.dejanews.com> (raw)
It looks to me like the whole point of the File_Access type in Ada.Text_IO is
to allow Standard_Output and Current_Output (and the same functions for Input
and Error) to be compared in order to see if I/O has been redirected somehow.
However, when I compile and execute a DOS program using ObjectAda on NT,
Ada.Text_IO.Current_Output and Ada.Text_IO.Standard_Output are *not* equal. If
I do an Ada.Text_IO to either, it gets printed in my shell window.
So if I can't use the equality operations of File_Access to see where output
is going, what was the type put in there for? There's nothing else other than
the Standard* and Current* functions that give me one, and the only
operations allowed are equality comparison and assignment.
T.E.D.
