nodejs c++ addon question

[late close]

Hello,  I am new in nodejs addon, I have a newbie question.

I have a class in C++ as following:

class CConfigInterface: public IKnown

{

public:

    virtual int  Load(const char *szFileName) = 0;

    virtual int  Save(const char *szFileName) = 0;

    virtual const char * GetString(const char *szSection, const char *szEntry, const char *szDefault) = 0;

    virtual int GetInt(const char *szSection, const char *szEntry, int iDefault) = 0;

    virtual int  SetString(const char *szSection, const char *szEntry, const char *szValue) = 0;

    virtual int SetInt(const char *szSection, const char *szEntry, int iValue) = 0;

};

which is defined in config,h

if I want to do: CConfigInterface * lpConfig = NewConfig(); in nodejs addon

what does the syntax looks in .cc file? Can I directly include "config.h"?

Thank you in advance.
