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

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

Description
The function informs the Intrinsics selection mechanism that a widget believes it owns a selection. It returns if the widget has success-
fully become the owner and 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 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, does noth-
ing.
After a widget has called 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 finishes after the
call to
