ACPI and Thermal zones

Hi

I try to get the data of the ACPI thermal zones. Currently I don't know how.
As far as I believe I must access the acpi.sys driver "in a way" to get the
data. Unfortunately I dont know how.
When I searched the web for references I found a program named
"mobilemeter". This programm accesses the ACPI in a way and displays the
thermal zone. It looks like this programm accesses the ACPI driver since no
driver is shipped with this program...

Hope anybody has a idea or example. I use VC++ for development...

Thnaks in advance

Some of the ACPI information is exposed through WMI.
If you are interested to this information from user-mode,
please search for `MSACPI_ThermalZoneTemperature`.

Great!

I searched the web but I did not find it in the MSDN described. Am I too
stupid or what is the problem?

From the documentation point of view,
the classes under root\WMI are advertised by installed drivers, and,
they are supposed to be self documenting, by virtue of having
a "textual" representation in the form of a MOF.

On most mobos and laptops of Pentium-III era the temperature sensors were
NOT available via WMI due to some ACPI issues in the BIOS. Only the chipset
dependent "motherboard monitors" or "AsusProbes" could help.

Maybe it is not so on more modern computers. Same situation is with the fan
speeds.
