ReadProcessorPwrScheme function

[ReadProcessorPwrScheme is available for use in the operating systems specified in the Requirements section. It may be altered or unavailable in subsequent versions. See Remarks.]

Applies to: desktop apps only

Retrieves the processor power policy settings for the specified power scheme.

Syntax

Copy

BOOLEAN WINAPI ReadProcessorPwrScheme(
  __in   UINT uiID,
  __out  PMACHINE_PROCESSOR_POWER_POLICY pMachineProcessorPowerPolicy
);

Parameters

uiID [in]: The index of the power scheme to be read.
pMachineProcessorPowerPolicy [out]: A pointer to a MACHINE_PROCESSOR_POWER_POLICY structure that receives the processor power policy settings.

Return value

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, call GetLastError.

Remarks

The MACHINE_PROCESSOR_POWER_POLICY structure contains processor power policy settings for use while the system is running on AC power or battery power.

Starting with Windows Vista, power management configuration of the system's processor is controlled through the GUID_PROCESSOR_SETTINGS_SUBGROUP power settings subgroup. Use the PowerEnumerate function to enumerate individual settings.
