Research of high-resolution timing methods in Windows 2000

Firstly,the necessity and the importance to realize the high-resolution timing in windows 2000 were pointed.Six high-resolution timing methods were expatiated,after that,the realization mechanisms and using means were analyzed and researched for every method,and the excellence and disadvantage of every method was also indicated.Considering the necessity of practice program-ming,a delay function was implemented by using every method correspondingly.Finally,the minimum precision and the maximum timing value of every high-resolution timing method were expatiated,including the best scopes where they are applied.
