cppreference.com 创建账户 std::condition_variable 在标头<condition_variable>定义 classcondition_variable; (C++11 起) std::condition_variable是与std::mutex一起使用的同步原语,它能用于阻塞一个线程,或同时阻塞多个线程,直至另一线程修改共享变量(条件)并通知std::condition_variable。

std::condition_variable - cppreference.com Acquire a std::mutex (typically via std::lock_guard). Modify the shared variable while the lock is owned. Call notify_one or notify_all on the std::condition_variable (can be done after releasing the lock). 随意,逻辑上不会出错。 如果先unlock然...

先贴一个condition_variable的讲解:https://en.cppreference.com/w/cpp/thread/condition_variable,很详细也很全面,但是是英文的,劝退了一部分英语不好的人(也包括我),但是借助翻译还是大概可以看下来的,而且里面的两个代码也很有代表性,使用的生产者消费者模式,推给大家。
我不能理解为什么这个cv是用局部变量。。。回到正题，遇到这种问题本来就是无解的，因为notify本来就是...
