Thread: GetTickCount()

My GetTickCount() seems to always return the same value.
Has this happened to you ?

Yes, for something like:

Code:

#include <windows.h>
#include <iostream>

int main()
{
int i=200;

while (i)
  {
  std::cout<<GetTickCount()<<"\n";
  --i;
  }

std::cout<<std::endl;
}

Put a call to 'Sleep' in before the GetTickCount call and it will update. This is because GetTickCount is not very accurate.

If you need a more precise timer then you can get millisecond precision with timeGetTime (if you set the period to 1ms with timeBeginPeriod). Windows also has high resolution timers but these may not be available with older machines - see QueryPerformanceCounter and QueryPerformanceFrequency. Search the boards, too, for these functions and 'timing'; I suspect you'll find previous discussions on the subject of timing that may be of interest.
