|
|
|
The
|
|
|
|
|
.I DPMSEnable
|
|
|
|
|
function enables Display Power Management Signaling (DPMS) on the specified
|
|
|
|
|
.I display.
|
|
|
|
|
When DPMS is enabled, DPMS will use the currently saved timeout values. It will
|
|
|
|
|
trigger the appropriate DPMS power level based on the timeout values. Refer to
|
|
|
|
|
.I DPMSSetTimeouts.
|
|
|
|
|
All physical screens are affected by
|
|
|
|
|
.I DPMSEnable
|
2006-11-25 09:46:32 -07:00
|
|
|
at the same time.
|
|
|
|
|
|
2012-03-10 07:01:58 -07:00
|
|
|
If
|
|
|
|
|
.I DPMSEnable
|
|
|
|
|
is invoked on a display which has DPMS already enabled, or on a display which
|
2006-11-25 09:46:32 -07:00
|
|
|
does not support DPMS, no change is made and no error is returned.
