The caller shall arrange receiving applicable X11 events, and pass them to ProcessKeyEvent() later.

Parameters:

	obj	VLC object owning an X window
	conn	XCB connection to the X server (to fetch key mappings)

Returns:

NULL on error, or a key handling context.

int ProcessKeyEvent	(	key_handler_t *	ctx,
		xcb_generic_event_t *	ev
	)
