但实际上我按照会虚假唤醒写法去触发,并没有触发出来,这里是代码,编译g++ -std=c++14 -pthread例子是cppref上改的,一个线程producer作为生产者,consumer/consumer2线程是两个消费者线程,如果队列里面有数据产生,producer发送notify_one出来,唤醒消费者线程.预期:两个等待状态的线程每次都被唤醒,而第一个个被唤醒的线...

问类上下文中的C++ std::condition_variableEN在 C++ 标准库中，std::transform() 是一个非常有用的算法函数，它能够将给定范围中的每个元素进行变换，并将变换后的结果存储到另一个范围中。换句话说，它可以通过应用一个指定的操作函数来对容器范围内的元素进行转换。
Edit & run on cpp.sh My expectation is this way, albeit I'm almost sure it's not completely correct: The program, as useful, starts from themain()function/thread, theworkerthread is the called on line 35. After that point, the program's control goes to theworker_threadfunction. Auniq...
