1. condition_variable和condition_variable_any类相似,前者只能使用unique_lock<mutex>来锁定线程,因为在condition_variable的内部将通过调用unique_lock的lock()函数来获取mutex,而诸如lock_guard对象并不提供lock()操作。后者可以使用任意类型的可锁定对象。 2.wait(lck)用于等待通知。而wait(lck,pred)会先判断pred条...

&g_mutex);才能lock这个mutex,不然的话,不然的话在生产者还没有释放mutex lock之前,消费者怎么能拿到这个锁呢, 所以我对之前的pthread_cond_wait(&g_cond, &g_mutex);有点疑问,我认为之前说法是等wait, 但是等待
The condition variable gives you the way to put them to sleep while they are waiting, simultaneously releasing the mutex and doing so in a way that avoids race conditions where you miss wake ups. Top Lost Wakeup and Spurious Wakeup 唤醒丢失(Lost Wakeup)和虚假唤醒(Spurious Wakeup) Lost wakeup...
wokeout getting in the way of good sleep? Don.t think your fat cells won.t notice. A new study published in The Annals of Internal Medicine (a medical journal) finds that inadequate shut-eye has a harmful effect on fat cells, reducing their ability to respond to insulin (胰岛素) by ...
qthread 和 QWaitCondition配合 的 阻塞流程 背景: 在QThread的run函数中执行耗时工作。 示例代码 void wakeThread::run() { m_waitcondition.wait(); #1 if(getThreadState()==STOP) #2 { break; } for(int i=0;i<1000;++) #3 { QThread::sleep(1); ... ... } } 问题: 多个线程(A,B...
