本文深入剖析了DW毫秒级延时算法的核心原理，通过详细阐述其工作流程和关键步骤，旨在为读者提供一种在特定应用中优化延迟响应时间的高效解决方案。通过引入高性能计时机制，该算法能够在毫秒级别内精确控制延迟，为各种实时系统和交互应用带来显著提升。文章不仅涵盖了理论基础，还提供了实际应用案例，帮助开发者更好地理解和实现这一算法。
void DelayTime(DWORD dwMilliseconds)
{
LARGE_INTEGER littmp;
LONGLONG lTimeBegin;
LONGLONG lTimeEnd;
double dMinus;
double dFreq;
double dTim;
QueryPerformanceFrequency(&littmp);
dFreq=(double)littmp.QuadPart;
QueryPerformanceCounter(&littmp);
lTimeBegin=littmp.QuadPart;
do
{
QueryPerformanceCounter(&littmp);
lTimeEnd=littmp.QuadPart;
dMinus=(double)(lTimeEnd-lTimeBegin);
dTim=dMinus/dFreq;
} while (dTim<dwMilliseconds*0.001);
}
{
LARGE_INTEGER littmp;
LONGLONG lTimeBegin;
LONGLONG lTimeEnd;
double dMinus;
double dFreq;
