Getting time more exact than millisecond

[onkelhotte]

Hi there,

I want to examine my code, so I can see, which subroutine and function takes how much time to execute. It is written in CVF6.6 and VS 6.

I tried enabling profiling in the linker section of project settings, but the subroutines I need to watch arent listed there, when I Profile function timings.

So I want to check the times before and after the subroutine, but CPU_TIME only returns in milliseconds and that is too inaccurate, because I get 0 or 0.01 seconds each time.

Is there a more accurate function or are there any other built in test methods for seeing the run-time behavior?

Thanks in advance

Look in the Win32 API documentation for "multimedia timers".

CPU_TIME and SYSTEM_CLOCK rely on the operating system updating timers, and the resolution of these is rather coarse, as you have found.
