Since it does not change any interfaces, just documents and commits existing ones, it requests a patch release binding. -Alan Coopersmith- alan.coopersmith@sun.com Sun Microsystems, Inc. - X Window System Engineering Some X clients need a reliable way to figure out if xscreensaver is running. For example, Sun Ray's utxlock tries to run xlock if it finds that xscreensaver is not running. Currently, there is no reliable way to do this that Sun has documented, but xscreensaver has long provided a status mechanism, which this case documents and commits to maintain. When Xscreensaver is running in an X session, an X window will be created as a child of the root window. When XGetClassHint is called on this window, it will return an XClassHint structure which has the 'res_class' field ("application class name") set to "XScreenSaver". When Xscreensaver has taken control of the screen, and either made it blank or is displaying the drawings of a screensaver "hack" module it will set a property on the root window named _SCREENSAVER_STATUS. If the screen can be returned to the normal state by just using one of the input devices to wake it up, without requiring any authentication, this property will contain an atom with atom_name "BLANK". If authentication will be required to return to the user session, this property will contain an atom with atom_name "LOCK". If the property does not exist or does not contain either atom, then xscreensaver is not currently controlling the screen.
