This is so hard for me as a beginner. I already spend more than thirty hour in this program. But the program doesn't work. The program continues run in the "while" loop in main function and never stop. I would be very aprciate if someone can help me. #include<stdio.h...

ConcurrentLinkedQueue是一个基于链接节点的无边界的线程安全队列,它采用FIFO原则对元素进行排序。采用“wait-free”算法(即CAS算法)来实现的。 CoucurrentLinkedQueue规定了如下几个不变性: 在入队的最后一个元素的next为null 队列中所有未删除的节点的item都不能为null且都能从head节点遍历到 ...
通过上面的图示,我们可以看到ConcurrentLinkedQueue在入队列过程中非常明显的一个特点就是tail指针不是实时更新的,即tail节点可能会滞后于队列中真正的最后一个节点,只有当最后的一个节点与tail节点之前的距离大于1时才会更新,而这样设计的目的就是为了减少避免每增加一个节点,tail节点都需要去执行一次CAS操作的情况发生。
在C++11中,有两个主要的与数据结构相关的特性:智能指针和基于范围的for循环。 1. 智能指针 (Smart Pointers):智能指针是一种对象,它像常规指针一样存储对象的地址,但当智能指针的生命周期结束时,它会自动删除它所指向的对象。这种自动管理内存的能力使得智能指针成为防止内存泄漏的重要工具。C++11引入了三种类型的智...
ConcurrentLinkedQueue提供了poll()方法进行出列操作。入列主要是涉及到tail,出列则涉及到head。我们先看源码: 代码语言:javascript 复制 publicEpoll(){// 如果出现p被删除的情况需要从head重新开始restartFromHead:// 这是什么语法?真心没有见过for(;;){for(Node<E>h=head,p=h,q;;){// 节点 itemEitem=p...
For example, the system can send an unsolicited message using tpnotify() without the TPACK() flag, or an application can send a message using tpacall() with the TPNOREPLY() flag. If the message queue of the receiving program is full, the message is dropped....
