[Gtk2hs-devel] Wrong binding for textBufferGetBounds ?

[Andy Stewart]

Today, i see function `gtk_text_buffer_get_bounds` document:

------------------------------> document start <------------------------------
/**
 * gtk_text_buffer_get_bounds:
 * @buffer: a #GtkTextBuffer 
 * @start: iterator to initialize with first position in the buffer
 * @end: iterator to initialize with the end iterator
 *
 * Retrieves the first and last iterators in the buffer, i.e. the
 * entire buffer lies within the range [...@start,@end).
 * 
 **/
void
gtk_text_buffer_get_bounds (GtkTextBuffer *buffer,
                            GtkTextIter   *start,
                            GtkTextIter   *end)
...
------------------------------> document end   <------------------------------

So textBufferGetBounds should be

     "TextBufferClass self => self -> IO (TextIter, TextIter)", 

and not current type signature

    "TextBufferClass self => self -> TextIter -> TextIter -> IO ()"
    
return `IO ()` haven't any sense.


Below is my new implement of `textBufferGetBounds`:

------------------------------> implement start <------------------------------
textBufferGetBounds :: TextBufferClass self => self -> IO (TextIter, TextIter)
textBufferGetBounds self = do
  start <- makeEmptyTextIter
  end   <- makeEmptyTextIter
  {# call unsafe text_buffer_get_bounds #}
     (toTextBuffer self)
     start
     end
  return (start, end)
------------------------------> implement end   <------------------------------

What do you think?
