在这两种情况下,都有一种有效的本机平台方法来对平台的本机 condition_variable 对应项执行等待,但它还需要本机互斥体句柄。因此,为了使用它,实现不仅需要完全访问 CV,还需要完全访问互斥锁。仅当外部类型都是实现的内部类型时才能完成此操作。std::condition_variable_any 没有这样的奢侈,它不能直接访问给定的互斥...
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 acquire a std::unique_lockstd::mutex, on the...
