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。
在wait返回时,并且调用线程会锁定lock。如果无法满足此后条件[1],那么就会调用std::terminate。 ↑重新锁定互斥体的过程中抛出异常就会发生这种情况。 参数 lock-必须已经由调用线程锁定的锁 stoken-用于注册中断的停止令牌 pred-检查是否可以完成等待的谓词
cppreference 给出的官方解释: A condition variable is an object able to block the calling thread until notified to resume. It uses a unique_lock (over a mutex) to lock the thread when one of its wait functions is called. The thread remains blocked until woken up by another thread that ...
从文档语言中我不清楚是否必须在等待之前检查 std::condition_variable 的谓词。在cppreference上,有这样的语句:Any thread that intends to wait on std::condition_variable has to 1. ... 2. check the condition, in case it was already updated and notified ...
