No sleep function windows 8

This behavior changed starting with Windows Server This function causes a thread to relinquish the remainder of its time slice and become unrunnable for an interval based on the value of dwMilliseconds. The system clock "ticks" at a constant rate. If dwMilliseconds is less than the resolution of the system clock, the thread may sleep for less than the specified length of time.

If dwMilliseconds is greater than one tick but less than two, the wait can be anywhere between one and two ticks, and so on. To increase the accuracy of the sleep interval, call the timeGetDevCaps function to determine the supported minimum timer resolution and the timeBeginPeriod function to set the timer resolution to its minimum.

Use caution when calling timeBeginPeriod , as frequent calls can significantly affect the system clock, system power usage, and the scheduler. If you call timeBeginPeriod , call it one time early in the application and be sure to call the timeEndPeriod function at the very end of the application. After the sleep interval has passed, the thread is ready to run.

If you specify 0 milliseconds, the thread will relinquish the remainder of its time slice but remain ready. Note that a ready thread is not guaranteed to run immediately.
