+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.
+.IP \fIlose_selection\fP 1i
+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.
+.IP \fIselection\fP 1i
+Specifies an atom that describes the type of the selection (for example,

+or
+.ZN XA_CLIPBOARD ).

+.IP \fItime\fP 1i
+Specifies the timestamp that indicates when the selection \*(Ti.

+.IP \fIw\fP 1i
+Specifies the widget \*(Wi.
+.SH DESCRIPTION
+The
+.ZN XtOwnSelection
+function informs the \*(xI selection mechanism that a
+widget believes it owns a selection.
+It returns
+.ZN True
+if the widget has successfully become the owner and
+.ZN 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.
+.LP
+The
+.ZN XtOwnSelectionInrcremental
+procedure informs the Intrinsics incremental selection mechanism that
+the specified widget wishes to own the selection. It returns
+.ZN True
+if the specified widget successfully becomes the selection owner or
+.ZN False
+otherwise. For more information about \fIselection\fP, \fItarget\fP,
+and \fItime\fP, see Section 2.6 of the \fIInter-Client Communication
+Conventions Manual\fP.
+.LP
+A widget that becomes the selection owner using
+.ZN XtOwnSelectionIncremental
+may use
+.ZN XtDisownSelection
+to relinquish selection ownership.
+.LP
+The
+.ZN XtDisownSelection
+function informs the \*(xI 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,
+.ZN XtDisownSelection
+does nothing.
+.LP
+After a widget has called
+.ZN 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
+.ZN XtDisownSelection
+finishes after the call to
+.ZN XtDisownSelection .
