XSetScreenSaver(3)		XLIB FUNCTIONS		    XSetScreenSaver(3)

       XSetScreenSaver, XForceScreenSaver, XActivateScreenSaver, XResetScreen‐
       Saver, XGetScreenSaver - manipulate the screen saver

       int XSetScreenSaver(Display *display, int timeout, int interval, int
	      prefer_blanking, int allow_exposures);

       int XForceScreenSaver(Display *display, int mode);

       int XActivateScreenSaver(Display *display);

       int XGetScreenSaver(Display *display, int *timeout_return, int *inter‐
	      val_return, int *prefer_blanking_return, int *allow_expo‐

		 Specifies the screen save control values.  You can pass Don‐
		 tAllowExposures, AllowExposures, or DefaultExposures.

		 Returns the current screen save control value (DontAllowExpo‐
		 sures, AllowExposures, or DefaultExposures).

       display	 Specifies the connection to the X server.

       interval	 Specifies the interval, in seconds, between screen saver

		 Returns the interval between screen saver invocations.

       mode	 Specifies the mode that is to be applied.  You can pass
		 ScreenSaverActive or ScreenSaverReset.

		 Specifies how to enable screen blanking.  You can pass Dont‐
		 PreferBlanking, PreferBlanking, or DefaultBlanking.

		 Returns the current screen blanking preference (Dont‐
		 PreferBlanking, PreferBlanking, or DefaultBlanking).

       timeout	 Specifies the timeout, in seconds, until the screen saver
		 turns on.

		 Returns the timeout, in seconds, until the screen saver turns

       Timeout and interval are specified in seconds.  A timeout of 0 disables
       the screen saver (but an activated screen saver is not deactivated),
       and a timeout of -1 restores the default.  Other negative values gener‐
       ate a BadValue error.  If the timeout value is nonzero, XSetScreenSaver
       enables the screen saver.  An interval of 0 disables the random-pattern
       motion.	Both values are limited to a 16-bit signed integer range by
       the wire protocol, despite the C prototype.  If no input from devices
       (keyboard, mouse, and so on) is generated for the specified number of
       timeout seconds once the screen saver is enabled, the screen saver is

       For each screen, if blanking is preferred and the hardware supports
       video blanking, the screen simply goes blank.  Otherwise, if either
       exposures are allowed or the screen can be regenerated without sending
       Expose events to clients, the screen is tiled with the root window
       background tile randomly re-origined each interval seconds.  Otherwise,
       the screens' state do not change, and the screen saver is not acti‐
       vated.  The screen saver is deactivated, and all screen states are
       restored at the next keyboard or pointer input or at the next call to
       XForceScreenSaver with mode ScreenSaverReset.

       If the server-dependent screen saver method supports periodic change,
       the interval argument serves as a hint about how long the change period
       should be, and zero hints that no periodic change should be made.
       Examples of ways to change the screen include scrambling the colormap
       periodically, moving an icon image around the screen periodically, or
       tiling the screen with the root window background tile, randomly re-
       origined periodically.

       XSetScreenSaver can generate a BadValue error.

       If the specified mode is ScreenSaverActive and the screen saver cur‐
       rently is deactivated, XForceScreenSaver activates the screen saver
       even if the screen saver had been disabled with a timeout of zero.  If
       the specified mode is ScreenSaverReset and the screen saver currently
       is enabled, XForceScreenSaver deactivates the screen saver if it was
       activated, and the activation timer is reset to its initial state (as
       if device input had been received).

       XForceScreenSaver can generate a BadValue error.

       The XActivateScreenSaver function activates the screen saver.

       The XResetScreenSaver function resets the screen saver.

       The XGetScreenSaver function gets the current screen saver values.

       BadValue	 Some numeric value falls outside the range of values accepted
		 by the request.  Unless a specific range is specified for an
		 argument, the full range defined by the argument's type is
		 accepted.  Any argument defined as a set of alternatives can
		 generate this error.
