timeBeginPeriod (Windows Embedded CE 6.0)

1/6/2010

This function sets the minimum timer resolution for an application or device driver.

Syntax

MMRESULT timeBeginPeriod(
  UINT uPeriod
);

Parameters

• uPeriod
  [in] Minimum timer resolution, in milliseconds, for the application or device driver.

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 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.
