std::condition_variable_any能与std::shared_lock一同使用,以在std::shared_mutex上以共享所有权模式等待。 std::condition_variable_any与自定义可锁定(Lockable)类型的一种可能用法,是提供便利的可中断等待:自定义的锁定操作按预期锁定关联的互斥体,并进行必要的设置,以在收到中断信号时通知此条件变量。[1] ...

大condition_variable_any类是std::condition_variable.鉴于std::condition_variable只在std::unique_lock<std::mutex>,,,condition_variable_any可以对满足BasicLockable所需经费。 见std::condition_variable用于描述条件变量的语义。 全班std::condition_variable_any是一个标准布局类。它不是可复制的、可移动的、可...
其中std::condition_variable 仅支持 std::unique_lock<std::mutex> 类型作为互斥量。 std::condition_variable_any 可以支持任意基本可锁定(BasicLockable)类型作为互斥量,例如 [C++14]std::shared_lock,但也就意味着它的效率低于 std::condition_variable。
cpp reference: conditional_variable Even if the shared variable is atomic, it must be modified under the mutex in order to correctly publish the modification to the waiting thread. Any thread that intends to wait on std::condition_variable has to ...
