Is there a standard API for retrieving the machine CPU speed ?
I know the info is in the registry:
HKEY_LOCAL_MACHINEHARDWARE\DESCRIPTION\System\CentralProcessor\0

I'm curious if there is a stanard way to get it.

thanks,
Avi.

Sorry,
Looking for a standard API call, not a library.
If you were wondering, I'm comparing API's of a few OS as a part of my research.

thanks,
Avi.

you mean in by programring

try c++builder there are some system components that will get it for you

or if you want it for dos as well take a comp that you know it's speed then make a loop and check how much time did it take for the comp to pass the loop then you can do it on any comp and colculate the comp speed

1. I'm working with VC++ 6.0
2. Still looking for a WIN32 call.
3. Why not using HKEY_LOCAL_MACHINEHARDWARE\DESCRIPTION\System\CentralProcessor\0

There is no Win32 API function to do what you want. The closest is the GetSystemInfo function.

Do you know when: HKEY_LOCAL_MACHINEHARDWARE\DESCRIPTION\System\CentralProcessor\0

is calculated and how accurate it is ?

I think that registry value is written when Windows is installed or there is any change to the CPU. The value is not 100% accurate.
