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 inter‐
ested 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.

(for example, or
time Specifies the timestamp that indicates when the selection

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 speci‐
fied 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 nothing.
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 wid‐
get owned the selection. However, its done procedure will be called if
a conversion that started before the call to finishes after the call to
