WebTherefore it is must to check if a given index position exists in the array or not before accessing element at that index position. To check if index position is valid or not, first we need to fetch the size of the array, and then we can check, if the given index position is either greater than or equal to zero and less than the size of the array. WebAug 4, 2013 · 上一篇《C++11 并发指南二(std::thread 详解)》中主要讲到了 std::thread 的一些用法，并给出了两个小例子，本文将介绍 std::mutex 的用法。 Mutex 又称互斥量，C++ 11中与 Mutex 相关的类（包括锁类型）和函数都声明在 头文件中，所以如果你需要使用 std::mutex，就必须包含 头文件。

WebA recursive mutex is a lockable object, just like mutex, but allows the same thread to acquire multiple levels of ownership over the mutex object. This allows to lock (or try-lock) the mutex object from a thread that is already locking it, acquiring a new level of ownership over the mutex object: the mutex object will actually remain locked owning the thread …

While it is neither the exclusive or most efficient way to accomplish this, it can be among the simplest to those familiar with the pattern. One waits on a std::condition_variable with a std::unique_lock. buddhist worship tiktok
