C++使用ICE实现两台主机通信实例

IT知识使用主机

最是人间留不住，朱颜辞镜花辞树。这篇文章主要讲述C++使用ICE实现两台主机通信实例相关的知识，希望能为你提供帮助。
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。

【C++使用ICE实现两台主机通信实例】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
