本文介绍Cocos2d-x中用于简化内存管理的一系列宏，包括安全删除对象、数组及释放引用等实用功能，帮助开发者有效避免指针操作带来的潜在错误。

用计数很巧妙也很方便，但大部分处理过程涉及指针，难免比较烦琐，也容易出错。针对这个问题，Cocos2d-x为我们准备了一系列辅助宏来简化代码，这些宏都包含在头文件“CCPlatform Macro.h”里。表2-2列出了与内存管理相关的宏。
表2-2　Cocos2d-x中与内存管理有关的宏

 

宏描　　述
CC_SAFE_DELETE(p)使用delete操作符删除一个C++对象p，如果p为NULL，则不进行操作
CC_SAFE_DELETE_ARRAY(p)使用delete[]操作符删除一个C++数组p，如果p为NULL，则不进行操作
CC_SAFE_FREE(p)使用free()函数删除p，如果p为NULL，则不进行操作
CC_SAFE_RELEASE(p)使用release()方法释放Cocos2d-x对象p的一次引用，如果p为NULL，则不进行操作
CC_SAFE_RELEASE_NULL(p)使用release()方法释放Cocos2d-x对象p的一次引用，再把p赋值为NULL。如果p已经为NULL，则不进行操作
CC_SAFE_RETAIN(p)使用reatin()方法增加Cocos2d-x对象p的一次引用。如果p为NULL，则不进行操作
C++性能卡脖子？3 招零拷贝_内存池_指针优化破局

本文深入剖析搜狗workflow高性能网络编程的三大核心技术：零拷贝技术通过iovec向量化IO和智能编码流实现数据零拷贝传输，减少CPU开销；内存池设计采用资源池和线程池对象复用策略，优化高频内存分配；智能指针则替代传统指针管理资源生命周期。这些技术的系统级优化显著提升了网络框架的性能和稳定性。

这也是一个内存清除， CC_SAFE_DELETE宏定义如下 #define CC_SAFE_DELETE(p) do { if(p) { delete (p); (p) = 0; } } while(0)     展开宏：CCAutoreleasePool::~CCAutoreleasePool(void) 2 { 3 do 4 {

 带指针的类，自己写析构函数的时候，想把指针安全的删除掉，可以如下写：#define SAFE_DELETE_ELEMENT( ptr ) if (ptr != NULL)      {                         delete ptr;           ptr = NULL;       }#define SAFE_DELETE_ARRAY( ptr ) if (

我发现学程序大家差不多都有相似的地方,当一个人从这个地方摔倒的时候,后续总是不断的有人摔摔的,从论坛的提问就能看出来,因为自己学习的时候是每一一个人带的情况下,独自研究c++,现在仍然记得做c++的第一个星期,每写一句代码都要查一下资料,搜索一下网络,差不多写三句代码都要查半天的痛苦了,好的是用了一个多月的时间,c++实现了入门,写出了完成端口,视频,Flash加密,破解了别人一个带有数学公式和化

<br /><br /> <br />safe_delete(p)的若干心得<br /><br /><br />#define safe_delete(p) do{ delete p; p=NULL; } while(false)  <br /><br /><br />    这种写法的意义不是显而易见的，而且还有另外一种版本的safe_delete()，在此就不写了，同样的令人费解——或者说让初学C++编程的人费解。<br /><br /><br />    其实如此做的目的就是为了让程序更健壮。<br

safe_delete(p)的若干心得
