C++使用ICE实现两台主机通信实例

ice使用过程跟google protocol buffer、gsoap类似，都是先写一个类似配置文件的东西，然后使用提供的工具生成相应语言的代码。

ice先写一个后缀名为.ice的文件，然后使用slice2cpp.exe生产对应c++代码，如下

module MCal
{
    interface Cal
    {
        int add(int num1,int num2);
        int sub(int num1,int num2);  
    };
};

其中MCal是生成c++类的命名空间，Cal是生成类的名字，add和sub是定义类的两个方法。

可以直接命令行执行slice2cpp Caculator.ice生成，也可以在vs中选择slice2cpp作为编译.ice的工具生成，下面是工具生成的代码

可以看到生成的类继承自Ice::Object，这点和ACE的使用又有点像了，只不过ACE要自己写类继承。调用的时候一个作为server端监听端口并提供对象访问点，client端连接端口并访问server端提供方法，上面生成的Caculator.h提供给client工程编译即可。
