将字符指针作为对VC ++中函数的引用进行传递

问题描述

您好，专家

在我的VC ++项目中，我正在调用方法

Hi Experts,

In my VC++ project I am calling the method

SaveErrorMsg(*"End-of-File");

通过传递字符指针.
但是我遇到了以下错误.

by passing a character pointer.
But I am getting the following error.

"cannot convert parameter 1 from 'char *' to 'char &'"

有人可以帮我吗?
我正在使用Visual Studio2008.

Can any one help me over this?
I am using Visual studio 2008.

SaveErrorMsg(*"End-of-File");// function call

void SaveErrorMsg(char &msg)
	{		
		// Do Something
	}

Thanks in advance.

推荐答案

void SaveErrorMsg(char &msg)
{
  // Do Something
}

它可能看起来应该像这样:

It should probably look like this:

void SaveErrorMsg(const char* msg)
{
  // Do Something
}

然后，您可以这样称呼它:

You would then call it like this:

SaveErrorMsg("End-of-File");// function call

这可能会更好:

This would probably be even better:

void SaveErrorMsg(const CString& msg)
{
  // Do Something
}
// Or this
void SaveErrorMsg(const std::string& msg)
{
  // Do Something
}
void SaveErrorMsg(const std::wstring& msg)
{
  // Do Something
}

最好的问候
