Stanford CS Education Library #102 一.Basic Pointers 指针主要有两个用途:使不同的代码段共享信息.方便链表(树)的处理. 指针示意图: dereference操作会根据指针的值去找到它的pointee. NULL是一个特殊的指针值(一般是地址0),表示这个指针不指向任何pointee. 指针的赋值会使得两个指针指向相同的pointee,但pointee本身不会改变: 传指针vs传值: 定义一个指针后,这个指针是没有被初始化的: 这时候如果进行de…

extention dll 1.指從MFC中繼承過來的DLL,一般要求使用共享MFC DLL進行連接,也要求調用者也使用MFC且使用共享MFC,如此可保證DLL與調用者有相同的MFC庫. 2.在使用資源的時候,打個比方說,加載一個對話框,會調用 AfxGetResourceInstance () 進行獲取HINSTANCE,這個函數會自動獲取DLL的 hInstance,所以,這牠不會造成調用者與DLL的資源混淆. normal dll 1.這個可以當成普通的DLL,調用者可以不是基於MFC編寫…

简介 MemProof(内存清道夫)是AutomatedQA出品的一款非常不错的检测内存泄漏和资源泄漏的免费调试工具,适合于WIN32平台下使用DELPHI/C++ BUILDER开发的应用程序. 利 用它可以方便的查找出 一些忘记释放的指针以及资源.它通过在调试模式下运行目标程序,监视程序的创建和释放操作,以达到检测资源泄漏的效果.监测过程中它会根据资源类型计数, 每次创建后增加计数,释放则递减计数,最后程序结束根据计数即可判断出资源的泄漏. MemProof的原作者是Atanas Stoya…

lock free数据结构一般来说拥有比基于lock实现的数据结构更高的性能,但是其实现比基于lock的实现更为复杂,需要处理的难题包括预防ABA问题,内存如何重用和回收等.通常,最简单最有效的处理ABA问题的方法是在目标内存区域加入一个tag,每次目标内存区域被更新或者被重用时增加tag.线程最后一次读取目标内存区域后tag没有改变,CAS操作才能成功.比如对于无锁链表来说,目标内存区域就是链表节点. 但是,在目标内存区域中包含tag这种方法,当所有线程都不再需要使用某块内存区域时,没有机制可…

一:架构概述 FreeRTOS是一个相对较小的应用程序.最小化的FreeRTOS内核仅包括3个(.c)文件和少数头文件,总共不到9000行代码,还包括了注释和空行.一个典型的编译后(二进制)代码映像小于10KB. FreeRTOS的代码可以分解为三个主要区块:任务,通讯,和硬件接口. ●任务:大约有一半的FreeRTOS的核心代码用来处理多数操作系统首要关注的问题:任务.任务是给定优先级的用户定义的C函数.task.c和task.h完成了所有有关创建,调度,和维护任务的繁重工作. ●通讯:任务很…
