[Process-Thread] bootstrap DL : 0: 这个频率与硬件和操作系统都可能有关。利用 API 函数 QueryPerformanceFrequency 可以得到这个定时器的频率。利用 API 函数 QueryPerformanceCounter 可以得到定时器的当前值。根据要延时的时间和定时器的频率, 可以算出要延时的时间定时器经过的周期数。在循环里用 QueryPerformanceCounter 不停的读出定时器值, 一直到经过了指定周期数再结束循环, 就达到-the frequency with hardware and the operating system are likely. Using API function can be QueryPerformanceFrequency the timing The frequency. QueryPerformanceCounter API function can be present timer value. According to the delay time and the frequency of the timer, you could calculate the time to delay timer after a few cycles. In the circle with QueryPerformanceCounter kept read timer value, until after a specified number of cycles end the cycle again, to achieve
