名称：互联网有害信息过滤1.0 功能：实时抓包，检测指定的有害信息 技术：使用原始套接字实现抓包功能 其他：本程序主要介绍使用原始套接字抓包的使用，希望对想了解这方面的朋友有点用。过滤部分很薄弱，如需当过滤系统使用，还需自行修改添加功能-Name: information filtering of harmful Internet 1.0 features: real-time capture, detection designated harmful information technology: the use of original socket capture realize other features: The program on the use of original capture the use of sockets, in the hope that it would like to know Friend a little used area. Filtering part is very weak, when the filtration system For use, needs to be modified to add functionality

信使小精灵,是一个简易的聊天工具。主要是演示了网络编程的主要步骤。本程序使用封装好的函数库，使得应用层不需要考虑网络消息是如何被接受和发送的，也不需要考虑数据粘包和丢包的刺手问题，你只要调用相应的函数就可以了。函数库为你做好了这些工作。你只需要定义自己的协议头和消息结构体，定义好网络消息的回调函数就可以了。 -messenger elf is a simple chat tools. A major demonstration is the main network programming steps. The programs use Packaging good libraries, makes application layer need not consider the network news is how it has been accepted and sent, and do not need sticky packets of data and packet loss of a thorn in hand, as long as you call the corresponding function on it. Functions well as your work. You only need to define its own agreement head and the structure of news, the definition of a good network news callback function on it.
