CPU_getProcessorSpeedInHZ
Returns the speed of the processor in Hz.
Declaration
void ZAPI CPU_getProcessorSpeedInHZ(
ibool accurate,
CPU_largeInteger *speed)
Prototype In
cpuinfo.h
Return Value
Accurate processor speed in Hz.
Description
This function returns the accurate speed of the CPU in Hz. Note that if the speed cannot be determined, this function will return 0.
This function is similar to the CPU_getProcessorSpeed function, except that it attempts to accurately measure the CPU speed in Hz. This is used internally in the Zen Timer libraries to provide accurate real world timing information. This is important for highly accurate timing using the Pentium RDTSC instruction, but it does take a lot longer for the profiling to produce accurate results.
