IOCTL_VIDEO_SET_POWER_MANAGEMENT control code

This IOCTL is obsolete in Windows 2000 and later, and is no longer supported. A Plug and Play video miniport driver should implement the HwVidSetPowerState function, which provides similar functionality.

Resets the power-consumption level of the adapter to the specified state. As long as the state is VideoPowerOff, the port driver intercepts and fails all IOCTL_VIDEO_XXX requests to the miniport driver until the next IOCTL_VIDEO_SET_POWER_MANAGEMENT request that resets the state to a power-on condition.

Input Parameters

The VRP InputBuffer contains the VIDEO_POWER_MANAGEMENT structure, specifying the state to be set.

Output Parameters

None

I/O Status Block

The miniport driver does not set the Information member of the STATUS_BLOCK structure.

Requirements

Header
