GetCpuFreqMhz
Estimates the processor operating frequency.
Syntax
IppStatus ippGetCpuFreqMhz(int* pMhz);
Include Files
ippcore.h
Parameters
pMhz |
Pointer to the result. |
Description
This function estimates the processor operating frequency and returns its value, in MHz as an integer stored in pMhz. The estimated value can vary depending on the processor workload.
To improve precision of the return value, this function accumulates CPU clocks. This operation takes several seconds and may result in long execution time.
Return Values
ippStsNoErr |
Indicates no error. |
ippStsNullPtrErr |
Indicates an error condition when the pMhz pointer is NULL. |
