The timeEndPeriod function clears a previously set minimum timer resolution.

Syntax

MMRESULT timeEndPeriod(
  UINT uPeriod
);

Parameters

uPeriod

Minimum timer resolution specified in the previous call to the timeBeginPeriod function.

Return value

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

Remarks

Call this function immediately after you are finished using 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.
