About Win32 api: QueryPerformanceFrequency !

[toptony]

Hi,guys!

I want to get the frequecy of my computer's motherboard with the Win32API QueryPerformanceFrequency().

The value is 3579545, but it's same as another computer's frequecy when i run my program on this compuer, but one computer is P4 2.3Hz, another is Celero 1.7Hz.Both them are Win XP SP2!

So I want to know the QueryPerformanceFrequency() is base on the OS or the hardware?

And How I get the hardware's frequency of my motherboard?

thanks!

QueryPerformanceFrequency() is irrelevant.
There are plenty of methods for p. freq.
You can ask on specialized win32 api newsgroup :
