I understand this is the performance respond to frequency, in ticks per second. Ns don"t know exactly how to convert this to a unit of time(let"s say seconds, milli-seconds or nano-seconds.. Anything) ?

How plenty of ticks constitute a second ? What is the conversion variable ?

LARGE_INTEGER freq;KeQueryPerformanceCounter(&freq);

*

In the link:

Remarks

KeQueryPerformanceCounter always returns a 64-bit integer that represents the existing value the a monotonically nondecreasing counter. The counter starts incrementing native zero when the computer system starts up.

You are watching: How many ticks are in a second

To gain the resolution of the timer offered to accumulate the current tick count, specify a non-NULL guideline value because that the PerformanceFrequency parameter. The frequency worth that the regimen writes come the place pointed to by this parameter is the number of ticks every second.

Here, it means that freq variable will contain ticks every second
