timeBeginPeriod

Syntax

WORD timeBeginPeriod(wPeriod)

This function sets the minimum (lowest number of milliseconds) timer resolution that an application or driver is going to use. Call this function immediately before starting to use timer-event services, and call timeEndPeriod immediately after finishing with the timer-event services.

Parameters

WORD wPeriod

Specifies the minimum timer-event resolution that the application or driver will use.

Return Value

Returns zero if successful. Returns TIMERR_NOCANDO if the specified wPeriod resolution value is out of range.

Comments

For each call to timeBeginPeriod, you must call timeEndPeriod with a matching wPeriod value. An application or driver can make multiple calls to timeBeginPeriod, as long as each timeBeginPeriod call is matched with a timeEndPeriod call.
