);

Parameters

  • pSystemPowerStatusEx2
    [out] Pointer to a buffer that receives power status information.

    In addition, the additional information might be different from platfrom to platform.

  • fUpdate
    [in] Specify TRUE to get the latest information from the device driver. Specify FALSE to get cached information that may be out-of-date by several seconds.
