QueryPerformanceFreqency and QueryPerformanceCounter

[1248]

hello , i try make a customizable delay out of QueryPerformanceFreqency and QueryPerformanceCounter i try is as i googled for 6+ hours and couldnot find anything to work with but i am not sure how to get it working.

Problem for me is that i have no idea how to use QueryPerformanceCounter so that value would be updating constantly not only 1 value and finished.
What sould i use in code to make values update itself very fast automatically?

for example id like QueryPerformanceCounter to update its value that is compared(<=) to calculation with fixed values. QueryPerformanceFreqency+QueryPerformanceCounter*2 to get a 2sec delay as soon as value is equal or larger than other and then
use if true to do delayed task.

How to make QueryPerformanceCounter update itself in comaprison to calculation that would be with fixed values?
