The classshared_lockis a general-purpose shared mutex ownership wrapper allowing deferred locking, timed locking and transfer of lock ownership. Locking ashared_locklocks the associated shared mutex in shared m

为std::shared_lock 特化std::swap 算法。交换 lhs 与rhs 的内部状态。相当于调用 lhs.swap(rhs)。 参数lhs, rhs - 要交换状态的锁包装器 返回值(无) 示例本节未完成原因:暂无示例 参阅swap 与另一 shared_lock 交换数据成员 (公开成员函数)

构造shared_lock ,可选地锁定提供的互斥。1) 构造 shared_lock ,不关联互斥。 2) 移动构造函数。以 other 的内容初始化 shared_lock 。令 other 不关联到互斥。 3-8) 构造 shared_lock ,以 m 为关联的互斥。另外: 3) 通过调用 m.lock_shared() ,以共享模式锁定关联的互斥。若此线程已以任何模式占有互...

注意:在编译的时候可能会报 underfined reference to ‘pthread_create’错误,这个在编译选项中加 -g -lpthread 既可。原因 具体编译命令: 1 g++-std=c++11lock.cpp-g-lpthread case 1:mutex #include <iostream>#include<thread>#include<mutex>usingnamespacestd;volatileintcounter(0); ...
根据cppreference,其中说 std::weak_ptr<T>::lock 有效返回expired() ? Shared_ptr() :shared_ptr(*this),原子执行。 这是示例代码。 #include<memory> #include<thread> std::shared_ptr<int> g_s = std::make_shared<int>(1); std::weak_ptr<int> w_p{g_s}; void f1(std::weak_ptr<int>...
