View the official Windows Driver Kit DDI referenceThe POWER_STATE union specifies a system power state value or a device power state value.
SystemStateA system power state value of type SYSTEM_POWER_STATE.
DeviceStateA device power state value of type DEVICE_POWER_STATE.
The POWER_STATE union is used in conjunction with the POWER_STATE_TYPE enumeration type to specify a system power state value or a device power state value. This union is also used in cases where the power state type is implicitly determined by the context in which it is used. For example, see PoRequestPowerIrp and PoSetPowerState.
