“函数已经有一个主体" [英] "function already has a body"

问题描述

这是什么意思?

1>c:\users\vitali\documents\visual studio 2010\projects\salam\tools.cpp(107): error C2084: function 'bool readXMLInteger(xmlNodePtr,const char *,int &)' already has a body
1>c:\users\vitali\documents\visual studio 2010\projects\salam\tools.h(52) : see previous definition of 'readXMLInteger'

tools.cpp(107):

tools.cpp(107):

bool readXMLInteger(xmlNodePtr node, const char* tag, int32_t& value)
{
    char* nodeValue = (char*)xmlGetProp(node, (xmlChar*)tag);
    if(nodeValue)
    {
        value = atoi(nodeValue);
        xmlFreeXOXL(nodeValue);
        return true;
    }

    return false;
}

tools.h(52)

tools.h(52)

bool readXMLInteger(xmlNodePtr node, const char* tag, int& value);

推荐答案

您是否在原始头文件中使用了包含保护?

Did you use include guards in your original header file?

例如:

#ifndef _TOOLS_H_
#define _TOOLS_H_

... your header body is here ...

#endif

这会阻止在每个包含它的 cpp 中重新定义.

This blocks against re-defining in each cpp where it is included.
