跨平台的网络通信,跟设备的集成控制,牵扯到在各种平台下的文件搜索问题,windows下面的已经有了。地址如下:http://blog.csdn.net/wangyaninglm/article/details/8668132这篇文章主要介绍一下linux下面的文件搜索实现:Filesearch.h/

跨平台的网络通讯,跟装备的集成控制,牵扯到在各种平台下的文件搜索问题,windows下面的已有了。

这篇文章主要介绍1下linux下面的文件搜索实现:

Filesearch.h

// // Filesearch.h // // // Created by mac mac on 13⑷⑵8. // Copyright (c) 2013年 __MyCompanyName__.

Filesearch.cpp:
