TODO: NOT YET DOCUMENTED.

Insert to add the specified window to the save set or Delete to delete it from the save set.

The window to add or delete to/from your save set.

TODO: explain what the save set is for.

This function either adds or removes the specified window to the client's (your application's) save set.

If you want to handle errors directly with xcb_request_check instead, use xcb_change_save_set_checked. See xcb-requests(3) for details.

You created the specified window. This does not make sense, you can only add windows created by other clients to your save set.
You specified an invalid mode.
The specified window does not exist.
