How to retrieve the time spent in user mode in a win32 process.

Question

I know that GetProcessTimes can be used to retrieve the time a process spent in user mode (as opposed to the time it spent in kernel mode or the time it was suspended). Unfortunately, it seems that the resolution is only 16ms (the same as GetTickCount).

Is there a way to retrieve the time with greater precision?

Answer 1

Take a look at QueryPerformanceCounter function. But I have heard that it has problems in multi core environments, not sure though.
