PowrProf
public static interface PowrProf.POWER_INFORMATION_LEVEL
Enum which indicates the power information level requested from PowrProf.CallNtPowerInformation(int, com.sun.jna.Pointer, int, com.sun.jna.Pointer, int). This value indicates the specific power information to be set or retrieved.

    • LastSleepTime

      static final int LastSleepTime
      The lpInBuffer parameter must be NULL; otherwise, the function returns WinError.ERROR_INVALID_PARAMETER.

      The lpOutputBuffer buffer receives a WinDef.ULONGLONG that specifies the interrupt-time count, in 100-nanosecond units, at the last system sleep time.

      static final int LastWakeTime
      The lpInBuffer parameter must be NULL; otherwise, the function returns WinError.ERROR_INVALID_PARAMETER.

      The lpOutputBuffer buffer receives a WinDef.ULONGLONG that specifies the interrupt-time count, in 100-nanosecond units, at the last system wake time.

    • ProcessorInformation

      static final int ProcessorInformation
      The lpInBuffer parameter must be NULL; otherwise, the function returns WinError.ERROR_INVALID_PARAMETER.

      The lpOutputBuffer buffer receives one WinNT.PROCESSOR_POWER_INFORMATION structure for each processor that is installed on the system. Use the Kernel32.GetSystemInfo(com.sun.jna.platform.win32.WinBase.SYSTEM_INFO) function to retrieve the number of processors, which will be the number of logical processors on the current Processor Group.

    • SystemBatteryState

      static final int SystemBatteryState
      The lpInBuffer parameter must be NULL; otherwise, the function returns WinError.ERROR_INVALID_PARAMETER.

      The lpOutputBuffer buffer receives a WinNT.SYSTEM_BATTERY_STATE structure containing information about the current system battery.

    • SystemExecutionState

      static final int SystemExecutionState
      The lpInBuffer parameter must be NULL otherwise, the function returns WinError.ERROR_INVALID_PARAMETER.

      The lpOutputBuffer buffer receives a WinDef.ULONG value containing the system execution state buffer. This value may contain any combination of the following values: WinBase.ES_SYSTEM_REQUIRED, WinBase.ES_DISPLAY_REQUIRED, or WinBase.ES_USER_PRESENT. For more information, see the Kernel32.SetThreadExecutionState(int) function.

    • SystemPowerCapabilities

      static final int SystemPowerCapabilities
      The lpInBuffer parameter must be NULL; otherwise, the function returns WinError.ERROR_INVALID_PARAMETER.

      The lpOutputBuffer buffer receives a WinNT.SYSTEM_POWER_CAPABILITIES structure containing the current system power capabilities.

      This information represents the currently supported power capabilities. It may change as drivers are installed in the system. For example, installation of legacy device drivers that do not support power management disables all system sleep states.

      The lpInBuffer parameter must be NULL; otherwise, the function returns WinError.ERROR_INVALID_PARAMETER.

      The lpOutputBuffer buffer receives a WinNT.SYSTEM_POWER_INFORMATION structure.

      Applications can use this level to retrieve information about the idleness of the system.

    • SystemPowerPolicyAc

      static final int SystemPowerPolicyAc
      If lpInBuffer is not NULL, the function applies the WinNT.SYSTEM_POWER_POLICY values passed in lpInBuffer to the current system power policy used while the system is running on AC (utility) power.

      The lpOutputBuffer buffer receives a WinNT.SYSTEM_POWER_POLICY structure containing the current system power policy used while the system is running on AC (utility) power.

    • SystemPowerPolicyDc

      static final int SystemPowerPolicyDc
      If lpInBuffer is not NULL, the function applies the WinNT.SYSTEM_POWER_POLICY values passed in lpInBuffer to the current system power policy used while the system is running on battery power.

      The lpOutputBuffer buffer receives a WinNT.SYSTEM_POWER_POLICY structure containing the current system power policy used while the system is running on battery power.

    • SystemReserveHiberFile

      static final int SystemReserveHiberFile
      If lpInBuffer is not NULL and the current user has sufficient privileges, the function commits or decommits the storage required to hold the hibernation image on the boot volume.

      The lpInBuffer parameter must point to a BOOLEAN value indicating the desired request. If the value is TRUE, the hibernation file is reserved; if the value is FALSE, the hibernation file is removed.
