Overview

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.

Return value

Returns an xcb_void_cookie_t. Errors (if any) have to be handled in the event loop.

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

Errors

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

xcb_value_error_t

You specified an invalid mode.

xcb_window_error_t

The specified window does not exist.
