+
+.SH DESCRIPTION
+Some extension
+.ZN XGenericEvents
+require additional memory to store information.
+For these events, the library returns a
+.ZN XGenericEventCookie
+with a token ('cookie') unique to this event. The
+.ZN XGenericEventCookie 's
+data pointer is undefined until
+.ZN XGetEventData
+is called.
+
+The
+.ZN XGetEventData
+function retrieves this extra data for the given cookie. No round-trip to
+the server is required. If the cookie is invalid or the
+event is not an event handled by cookie handlers,
+.ZN False
+is returned. If
+.ZN XGetEventData
+returns
+.ZN True ,
+the cookie's data pointer points to the memory containing the event
+information. A client must call
+.ZN XFreeEventData
+to free this memory.
+.ZN XGetEventData
+returns
+.ZN False
+for multiple calls for the same event cookie.
+
+The
+.ZN XFreeEventData
+function frees the data associated with a cookie. A client must call
+.ZN XFreeEventData
+for each cookie claimed with
+.ZN XGetEventData .
+
+.SH EXAMPLE CODE

+.TA .5i 3i
+.ta .5i 3i
+XEvent event;
+XGenericEventCookie *cookie = &ev;
+
+XNextEvent(display, &event);
+if (XGetEventData(display, cookie)) {
+ handle_cookie_event(cookie->data);
+} else
+ handle_event(&event);
+}
+XFreeEventData(display, cookie);
+.De
+
+.SH NOTES
+A cookie is defined as unclaimed if it has been returned to the client
+through
+.ZN XNextEvent
+but its data has not been retrieved via
+.ZN XGetEventData .
+Subsequent calls to
+.ZN XNextEvent
+may free memory associated with unclaimed cookies.
+Multi-threaded X clients must ensure that
+.ZN XGetEventData
+is called before the next call to
+.ZN XNextEvent .
