Performing measures within the execution of a c++ code every t milliseconds
- by user506901
Given a while loop and the function ordering as follows:
int k=0;
int total=100;
while(k<total){
doSomething();
if(approx. t milliseconds elapsed) { measure(); }
++k;
}
I want to perform 'measure' every t-th milliseconds. However, since 'doSomething' can be close to the t-th millisecond from the last execution, it is acceptable to perform the measure after approximately t milliseconds elapsed from the last measure.
My question is: how could this be achieved?
One solution would be to set timer to zero, and measure it after every 'doSomething'. When it is withing the acceptable range, I perform measures, and reset. However, I'm not which c++ function I should use for such a task. As I can see, there are certain functions, but the debate on which one is the most appropriate is outside of my understanding. Note that some of the functions actually take into account the time taken by some other processes, but I want my timer to only measure the time of the execution of my c++ code (I hope that is clear). Another thing is the resolution of the measurements, as pointed out below. Suppose the medium option of those suggested.
