NAME

       DPMSForceLevel - forces a DPMS capable display into the specified power level

SYNOPSIS

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

       Status DPMSForceLevel ( Display *display, CARD16 level );

ARGUMENTS

       display
	      Specifies the connection to the X server

       level  Specifies the level to force power to

DESCRIPTION

       The  DPMSForceLevel function forces a DPMS capable display into the specified power level.  The level must be one of following four states:
       DPMSModeOn, DPMSModeStandby, DPMSModeSuspend, or DPMSModeOff. Values other than these will result in a BadValue error.  If DPMS is disabled
       on the display, trying to set the power level on the display will result in a BadMatch protocol error.

RETURN VALUES

       TRUE	      The DPMSForceLevel function always returns TRUE.

ERRORS

       BadValue       A level other than DPMSModeOn, DPMSModeStandby, DPMSModeSuspend, or DPMSModeOff was specified.

       BadMatch       DPMS is disabled on the specified display.
