Minimum Processor State API

[Yasz]

Hi,

My question about the following available setting option in windows :
In windows and under Power option ==> advance power setting ==> Processor Power Management ==> Minimum Processor State ( Can be set as percentage%)

What is the corresponding API structure to this value, I would like to write a program which can control the % of the minimum and maximum processor state. I tried , SYSTEM_POWER_INFO, SYSTEM_POWER_CAPABILITY, .., nothing mentioned about this value.

Pls advise.

Regards,
