Absoliutus Vėlavimas į C / C pagal laimėti 98/xp/nt

[visweswara]

Kaip programa kurti realaus laiko atidėjimo mikrosekundę arba millisecond naudojant C / C po langais 98/xp/nt?

jums reikia

tuščia delaySeconds (float sekundžių)
(
__int64 timeEllapsed;
__int64 timeStart;
__int64 timeDelta;

QueryPerformanceFrequency ((LARGE_INTEGER *) (& timeDelta));
QueryPerformanceCounter ((LARGE_INTEGER *) (& timeStart));

__int64 timeToWait = (double) timeDelta * (double) sekundžių;

timeEllapsed = timeStart;

while ((timeEllapsed - timeStart) <timeToWait)
(
QueryPerformanceCounter ((LARGE_INTEGER *) (& timeEllapsed));

);
)

tuščia delayMiliSeconds (float miliseconds)
(
__int64 timeEllapsed;
__int64 timeStart;
__int64 timeDelta;

QueryPerformanceFrequency ((LARGE_INTEGER *) (& timeDelta));

__int64 timeToWait = (double) timeDelta * (double) miliseconds/1000.0f;

QueryPerformanceCounter ((LARGE_INTEGER *) (& timeStart));

timeEllapsed = timeStart;

while ((timeEllapsed - timeStart) <timeToWait)
(
QueryPerformanceCounter ((LARGE_INTEGER *) (& timeEllapsed));

);
)

tuščia delayMicroSeconds (float ms)
(
__int64 timeEllapsed;
__int64 timeStart;
__int64 timeDelta;

QueryPerformanceFrequency ((LARGE_INTEGER *) (& timeDelta));

__int64 timeToWait = (double) timeDelta * (double) mikrosekundžių / 1000000.0f;

QueryPerformanceCounter ((LARGE_INTEGER *) (& timeStart));

timeEllapsed = timeStart;

while ((timeEllapsed - timeStart) <timeToWait)
(
QueryPerformanceCounter ((LARGE_INTEGER *) (& timeEllapsed));

);
)
