Member Function Documentation

SbBool SbCondVar::wait

(

SbMutex &

mutex

)

[inline]

This method blocks the calling thread until another thread calls wakeOne() or wakeAll() on the SbCondVar object.

SbBool SbCondVar::timedWait	(	SbMutex &	mutex,
		SbTime	period
	)		[inline]

This method blocks the calling thread until another thread calls wakeOne() or wakeAll() on the object, but if this does not happen within period, the thread is woken again anyways.

TRUE is returned when the thread wakes because either wakeOne() or wakeAll() was called, FALSE is returned if the wait times out.
