dpmssettimeouts

DPMSSetTimeouts(3)						    X FUNCTIONS 						DPMSSetTimeouts(3)

NAME

       DPMSSetTimeouts - permits applications to set the timeout values used by the X server for DPMS timings

SYNOPSIS

       cc [ flag ... ] file ... -lXext [ library ... ]
       #include <X11/extensions/dpms.h>

       Status DPMSSetTimeouts
	      (
		    Display *display,
		    CARD16 standby,
		    CARD16 suspend,
		    CARD16 off
	      );

ARGUMENTS

       display
	      Specifies the connection to the X server

       standby
	      Specifies the new standby timeout in seconds

       suspend
	      Specifies the new suspend timeout in seconds

       off    Specifies the new off timeout in seconds

DESCRIPTION

       The  DPMSSetTimeouts  function  permits	applications to set the timeout values used by the X server for Display Power Management Signaling
       (DPMS) timings.

       The value standby is the amount of inactivity time, in seconds, before standby mode is invoked. The actual effects of this mode are  depen-
       dent  on  the characteristics of the monitor and frame buffer card. Standby mode is implemented by shutting off the horizontal sync signal,
       and pulsing the vertical sync signal. Standby mode provides the quickest monitor recovery time.	Note also  that  many  monitors  implement
       this mode identical to suspend mode.  A value of zero disables the standby mode.

       The  value  suspend  is	the  amount of time of inactivity, in seconds, before the second level of power savings is invoked. Suspend mode's
       physical and electrical characteristics are implementation defined. For DPMS compliant hardware, setting the suspend mode is implemented by
       pulsing the horizontal sync signal and shutting off the vertical sync signal.  In general, suspend mode recovery is considered to be slower
       than standby mode, but faster than off mode. However it may vary from monitor to monitor.  As noted above,  many  monitors  implement  this
       mode identical to the standby mode.  A value of zero disables this mode.

       The  value  off	is  the  amount of time of inactivity,in seconds, before the third and final level of power savings is invoked. Off mode's
       physical and electrical characteristics are implementation defined. In DPMS compliant hardware, it is implemented by shutting off both hor-
       izontal	and  vertical  sync  signals,  resulting in powering down of the monitor.  Recovery time is implementation dependent.  Usually the
       recovery time is very close to the power-up time of the monitor. A value of zero disables this mode.

       Chronologically, standby mode occurs before or simultaneously with suspend mode, and suspend mode must occur before or simultaneously  with
       off  mode.   Therefore, non-zero mode timeout values must be greater than or equal to the timeout values of earlier modes.  If inconsistent
       values are supplied, a BadValue error will result.

RETURN VALUES

       TRUE	      The DPMSSetTimeouts function returns TRUE when the function has succeeded.

ERRORS

       BadValue       An argument is out of range.
