If a high-resolution performance counter exists on the system, the QueryPerformanceFrequency function can be used to express the frequency, in counts per second. The value of the count is processor dependent. On some processors, for example, the count might be the cycle rate of the processor clock.
The '''QueryPerformanceCounter''' function retrieves the current value of the high-resolution performance counter (if one exists on the system). By calling this function at the beginning and end of a section of code, an application essentially uses the counter as a high-resolution timer. For example, suppose that '''QueryPerformanceFrequency''' indicates that the frequency of the high-resolution performance counter is 50,000 counts per second. If the application calls '''QueryPerformanceCounter''' immediately before and immediately after the section of code to be timed, the counter values might be 1500 counts and 3500 counts, respectively. These values would indicate that .04 seconds (2000 counts) elapsed while the code executed.
