本文介绍了一个使用 FeBird RPC 框架实现的简单客户端-服务器示例。该示例包括一个回显服务，服务器接收消息并返回带有前缀的相同消息。客户端连续发送输入直到文件结束。

// echo.h

class Echo : public GlobaleScope
{
public:
	BEGIN_RPC_ADD_MF(Echo)
		RPC_ADD_MF(echo)
	END_RPC_ADD_MF()

	// 3rd macro param is ';' means non-pure-virtual
	RPC_DECLARE_MF_EX(echo, (const std::string& msg, std::string* y), ;)
};
RPC_TYPEDEF_PTR(Echo);

rpc_return_t Echo::echo(const std::string& msg, std::string* y)
{
	cout << "input: " << msg << endl;
	*y = "server: " + msg;
	return 0;
}

int main(int argc, char** argv[])

		// 加入命名的 Servant
		server.add_servant(
			new Echo,
			"echo",
			0 // 0 will not auto create GlobaleScope Object
			);

		server.start();
	}
