This is very operating system dependent. There is no guarantee that
Ada.Text_IO files will allow this.

If the two tasks are part of the same program, have them share an

If you are writing your own file package, you should not try build it
on top of Text_IO.

You might be able to use Ada.Streams.Stream_IO instead.
