Returns TIMERR_NOERROR, if successful, or TIMERR_NOCANDO, if the resolution specified in uPeriod is out of range.

Call this function immediately before using timer services, and call the timeEndPeriod function immediately after you finish using the timer services.

You must match each call to timeBeginPeriod with a call to timeEndPeriod, specifying the same minimum resolution in both calls.

An application can make multiple timeBeginPeriod calls as long as each call is matched with a call to timeEndPeriod.
