[WriteProcessorPwrScheme is available for use in the operating systems specified in the Requirements section. It may be altered or unavailable in subsequent versions. See Remarks.]
Writes processor power policy settings for the specified power scheme.
The index of the power scheme to be written.
A pointer to a MACHINE_PROCESSOR_POWER_POLICY structure that contains the power policy settings to be written.
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.
This change does not affect the current system power policy. To apply this change to the current system power policy, call the SetActivePwrScheme function, using the index of this power scheme.
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.
For more information on using PowrProf.h, see Power Schemes.
