恢复QMutex和QWait 条件
原标题:Reusing QMutex and QWaitCondition

Are QMutex+QWaitCondition objects reusable? I have a method to wait for some threads to complete.

void FinishWait()
{
    mutex.lock();
    waitCondition(&qMutex, ULONG_MAX);
}

等待条件:觉醒一(a)被打到不同的十字路口。

第1次呼吁FinishWait()工作,但第2次呼吁并没有返回,即使我规定了时间。

最佳回答

假设“互惠”和“qMutex”是指相同的变数(否则就没有什么意义),那么,在等待(或)返回后,你必须打破mut。

void FinishWait()
{
    mutex.lock();
    waitCondition.wait(&mutex);
    mutex.unlock();
}
