Field Detail
-
LastSleepTime
static final int LastSleepTime
ThelpInBufferparameter must beNULL; otherwise, the function returnsWinError.ERROR_INVALID_PARAMETER.The
lpOutputBufferbuffer receives aWinDef.ULONGLONGthat specifies the interrupt-time count, in 100-nanosecond units, at the last system sleep time.- See Also:
- Constant Field Values
-
LastWakeTime
static final int LastWakeTime
ThelpInBufferparameter must beNULL; otherwise, the function returnsWinError.ERROR_INVALID_PARAMETER.The
lpOutputBufferbuffer receives aWinDef.ULONGLONGthat specifies the interrupt-time count, in 100-nanosecond units, at the last system wake time.- See Also:
- Constant Field Values
-
ProcessorInformation
static final int ProcessorInformation
ThelpInBufferparameter must beNULL; otherwise, the function returnsWinError.ERROR_INVALID_PARAMETER.The
lpOutputBufferbuffer receives oneWinNT.PROCESSOR_POWER_INFORMATIONstructure for each processor that is installed on the system. Use theKernel32.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.- See Also:
- Constant Field Values
-
SystemBatteryState
static final int SystemBatteryState
ThelpInBufferparameter must beNULL; otherwise, the function returnsWinError.ERROR_INVALID_PARAMETER.The
lpOutputBufferbuffer receives aWinNT.SYSTEM_BATTERY_STATEstructure containing information about the current system battery.- See Also:
- Constant Field Values
-
SystemExecutionState
static final int SystemExecutionState
ThelpInBufferparameter must beNULLotherwise, the function returnsWinError.ERROR_INVALID_PARAMETER.The
lpOutputBufferbuffer receives aWinDef.ULONGvalue containing the system execution state buffer. This value may contain any combination of the following values:WinBase.ES_SYSTEM_REQUIRED,WinBase.ES_DISPLAY_REQUIRED, orWinBase.ES_USER_PRESENT. For more information, see theKernel32.SetThreadExecutionState(int)function.- See Also:
- Constant Field Values
-
SystemPowerCapabilities
static final int SystemPowerCapabilities
ThelpInBufferparameter must beNULL; otherwise, the function returnsWinError.ERROR_INVALID_PARAMETER.The
lpOutputBufferbuffer receives aWinNT.SYSTEM_POWER_CAPABILITIESstructure 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.
- See Also:
- Constant Field Values
-
SystemPowerInformation
static final int SystemPowerInformation
ThelpInBufferparameter must beNULL; otherwise, the function returnsWinError.ERROR_INVALID_PARAMETER.The
lpOutputBufferbuffer receives aWinNT.SYSTEM_POWER_INFORMATIONstructure.Applications can use this level to retrieve information about the idleness of the system.
- See Also:
- Constant Field Values
-
SystemPowerPolicyAc
static final int SystemPowerPolicyAc
IflpInBufferis notNULL, the function applies theWinNT.SYSTEM_POWER_POLICYvalues passed inlpInBufferto the current system power policy used while the system is running on AC (utility) power.The
lpOutputBufferbuffer receives aWinNT.SYSTEM_POWER_POLICYstructure containing the current system power policy used while the system is running on AC (utility) power.- See Also:
- Constant Field Values
-
SystemPowerPolicyCurrent
static final int SystemPowerPolicyCurrent
ThelpInBufferparameter must beNULL; otherwise, the function returnsWinError.ERROR_INVALID_PARAMETER.The
lpOutputBufferbuffer receives aWinNT.SYSTEM_POWER_POLICYstructure containing the current system power policy used while the system is running on AC (utility) power.- See Also:
- Constant Field Values
-
SystemPowerPolicyDc
static final int SystemPowerPolicyDc
IflpInBufferis notNULL, the function applies theWinNT.SYSTEM_POWER_POLICYvalues passed inlpInBufferto the current system power policy used while the system is running on battery power.The
lpOutputBufferbuffer receives aWinNT.SYSTEM_POWER_POLICYstructure containing the current system power policy used while the system is running on battery power.- See Also:
- Constant Field Values
-
SystemReserveHiberFile
static final int SystemReserveHiberFile
IflpInBufferis notNULLand 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
BOOLEANvalue indicating the desired request. If the value isTRUE, the hibernation file is reserved; if the value isFALSE, the hibernation file is removed.- See Also:
- Constant Field Values
