Mingw使用HPSocket的包装类

首先，HPSocket是一个很好的开源网络项目，支持跨平台，Windows,Linux，Android,MacOS等等。但是就Windows平台而言，它的开发环境是VisualStudio。由于c++编译器的差异，Mingw和Mingw64是无法调用HPSocket的c++动态链接库的，因此我们只能使用HPSocket的c语言动态库。但是对于习惯使用c++的人来说，使用c语言是一件感觉很不好的事，就像现代人，突然回到了原始社会一样，在c语言中，没有c++的各种武器，并且函数、变量分散，阅读代码困难。因此自己抛砖引玉，对HPSocket做了下简单的包装，代码如下。
