lock()。2) 获得互斥体 m 的所有权而不试图锁定它。若当前线程不在 m 上保有非共享锁(即由 lock、try_lock、try_lock_for 或try_lock_until 取得的锁)则行为未定义。3) 复制构造函数被弃置。若m 先于lock_guard 对象被销毁,则行为未定义。 参数m - 要获得所有权的共享互斥体 t - 用于选择构造

平时看代码时,也会使用到std::lock_guard,但是std::unique_lock用的比较少。在看并发编程,这里总结一下。方便后续使用。 std::unique_lock也可以提供自动加锁、解锁功能,比std::lock_guard更加灵活。 std::lock_guard std::lock_guard是RAII模板类的简单实现,功能简单。

关于您提到的“binding reference of type 'std::lock_guard<std::mutex>::mutex_type&'”错误,这通常意味着在代码中尝试将一个std::lock_guard<std::mutex>::mutex_type&(即std::mutex&)类型的引用绑定到了不合适的对象上。以下是对这个问题的详细分析和可能的解决方案: 1. 理解问题背景...
