C++ 不确定如何装饰我的C++；C语言中使用的库代码

我们定义了一些方法，以便在需要时允许临时控制台输入。这些方法包含在名称空间中，并定义和使用类来执行实际工作

为简洁起见，将定义简化为：

控制台输入.h

#include <cstddef>
#include <map>
#include <memory>
#include <vector>

namespace MyNameSpc
{

typedef std::vector<char> buffer_t;

class ConsoleInput

// Methods for windows and linux console input
}

int GetString(buffer_t &buffer, ...);

}

#include "ConsoleInput.h"
#include <cstddef>
#include <string>

namespace MyNameSpc
{

const std::string empty = std::string();

class RequestInputParam
{
// Methods
}

int RequestInput(buffer_t &buffer);
int RequestInput(buffer_t &buffer, const RequestInputParam &param);
// and other overloads
}

它目前抛出了以下错误（I C&p仅在第一部分，它开始重复；行号与上面的代码不匹配，上面的代码已删除所有注释，因此我添加了注释和注释行#）：

我怀疑文章中被称为“副本”的答案只是写出来的，没有经过测试。经过更多的搜索，我最终偶然发现了它，它提供了构建该平台所需的指导

简而言之，我在我的C++包装代码（FACEPALM）中缺少命名空间，我必须添加RealTytCasic调用。我还更改了typedef中类型的名称。。。我认为它是引用C++类型（因为这是至少一个例子显示），但是，不…它需要是它自己的结构类型
