关于“求精度更高的Sleep函数”后续

void Sender()
{
	LARGE_INTEGER time1, time2, nFreq;
	QueryPerformanceFrequency(&nFreq);
	while (1)
	{
		QueryPerformanceCounter(&time1);
		Sleep(10);//先粗略睡眠一段时间，避免占用过多cpu
		QueryPerformanceCounter(&time2);
		while ((double)(time2.QuadPart - time1.QuadPart)/(double)nFreq.QuadPart < 0.02f)//0.02f就是指睡眠的时间：20ms即0.02s
			QueryPerformanceCounter(&time2);
		std::thread a(Work);
		a.detach();
	}
}
