+   --  functions.

+
+   ---------------------------------
+   -- Control of Text/Binary Mode --
+   ---------------------------------
+
+   --  If text_translation_required is true, then the following functions may
+   --  be used to dynamically switch a file from binary to text mode or vice
+   --  versa. These functions have no effect if text_translation_required is
+   --  false (i.e. in normal unix mode). Use fileno to get a stream handle.
