在编译代码时,我一直收到错误: error C2248: 'boost::mutex::mutex' : cannot access private member declared in class 'boost::mutex' 通过在线阅读,我发现使用Boost的lock_guard,结果如下所示 PointPorcessor processor = PointProcessor(x,y,z); 创建类的实例并将其赋值给processor变量。( 浏览1提问于2013...

同步原语和锁 Mutex 锁状态 type Mutex struct { state int32 sema uint32 } Mutex 结构体只有两个字段: state 表示锁状态...当队列中最后一个 goroutine 被执行或者它的等待时间低于 1 ms 时,会将该锁的状态切换回正常 Loc...
互斥锁/量(mutex):提供了以排他方式防止数据结构被并发修改的方法。 读写锁(reader-writer lock):允许多个线程同时读共享数据,而对写操作是互斥的。 自旋锁(spin lock)与互斥锁类似,都是为了保护共享资源。互斥锁是当资源被占用,申请者进入睡眠状态;而自旋锁则循环检测保持着是否已经释放锁。 条件变量(condition)...
