摘要：
今天，我想和大家分享一个最近使用的基本技能：ini文件的使用。最近的项目组没有外部eeprom。在应用程序运行时打开/关闭数据保存是一个问题，因此最常见的方法是使用ini文件。lpFileName）36return0；3738//打开文件并将文件数据复制到缓冲区g_PData，返回INI文件大小39if40｛41RETAILMG；42return0；43｝4445cchCopied=0；46while（0！=）47｛48//RETAILMG；49//是注释行50if51continue；5253//是段名54if55｛56//是段名57if58｛59//查找键名60while（1！
今天和大家分享最近用到的一个基础技能：ini文件的使用
最近的项目arm没有外接eeprom，运行过程中应用程序开开关关数据的保存是个问题
所以用最常见的方式ini文件。
最开始我把ini文件存在nand flash中，但是后来发现使用的nand的擦写次数仅有10000次
于是就把ini放置在内存文件夹中
下面具体展示下代码
首先是 封装好的代码不是我写的，是网上收集的，这个算是写的不错的：

需要注意的是，这样的保存并不适用与断电，因为是在内存文件夹
所以断电的话，我会把所有数据发送到MCU的eeprom，上电首先MCU会发给arm初始化信息
呵呵！算是给和我一样的新人一个提醒，不要随便擦写，特别是nand flash
文中并么有详细讲解代码，大家有何指教或疑问留言，我会一一回复的！共同进步！！！
