  NAME

  SYNTAX
       Boolean XtOwnSelection(w, selection, time, convert_proc,
       lose_selection, done_proc)
             Widget w;
             Atom selection;
             Time time;
             XtConvertSelectionProc convert_proc;
             XtLoseSelectionProc lose_selection;

       void XtDisownSelection(w, selection, time)
             Widget w;
             Atom selection;
             Time time;

  ARGUMENTS
       convert_proc
                 Specifies the procedure that is to be called
                 whenever someone requests the current value of the
                 selection.

       done_proc Specifies the procedure that is called after the
                 requestor has received the selection or NULL if
                 the owner is not interested in being called back.

       lose_selection
                 Specifies the procedure that is to be called
                 whenever the widget has lost selection ownership
                 or NULL if the owner is not interested in being
                 called back.

       selection Specifies an atom that describes the type of the
                 selection (for example, XA_PRIMARY, XA_SECONDARY,
                 or XA_CLIPBOARD).

       time      Specifies the timestamp that indicates when the
                 selection ownership should commence or is to be

                 relinquished.

       w         Specifies the widget that wishes to become the
                 owner or to relinquish ownership.

  DESCRIPTION
       The XtOwnSelection function informs the Intrinsics selection
       mechanism that a widget believes it owns a selection.  It
       returns True if the widget has successfully become the owner
       and False otherwise.  The widget may fail to become the
       owner if some other widget has asserted ownership at a time
       later than this widget.  Note that widgets can lose
       selection ownership either because someone else asserted
       later ownership of the selection or because the widget
       voluntarily gave up ownership of the selection.  Also note
       that the lose_selection procedure is not called if the
       widget fails to obtain selection ownership in the first
       place.

       The XtDisownSelection function informs the Intrinsics
       selection mechanism that the specified widget is to lose
       ownership of the selection.  If the widget does not
       currently own the selection either because it lost the
       selection or because it never had the selection to begin
       with, XtDisownSelection does nothing.

       After a widget has called XtDisownSelection, its convert
       procedure is not called even if a request arrives later with
       a timestamp during the period that this widget owned the
       selection.  However, its done procedure will be called if a
       conversion that started before the call to XtDisownSelection
       finishes after the call to XtDisownSelection.
