Overloaded instance of C++ 's CNoTrackObject class and new delete operator

This article illustrates the overloading of the CNoTrackObject class and the new delete operator in C++. The details are as follows:

Header:

class CNoTrackObject{  

public: //In this case, public is not added as the private variable of the class by default, and MyThreadData cannot access the member variable & NBSP; after inheriting this class. < br / >
    void* operator new(size_t nSize);  

    void operator delete(void*);  

    virtual ~CNoTrackObject(){}  

};

The implementation method is as follows:

void* CNoTrackObject::operator new(size_t nSize)  

{  

    //Request a piece of memory & NBSP; < br / >
    void* p = ::GlobalAlloc(GPTR , nSize);  

    return p;  

}  

  

void CNoTrackObject::operator delete(void* p)  

{  

    if (p != NULL)  

    {  

        ::GlobalFree(p);  

    }  

}

The use process is as follows:

struct MyThreadData:public CNoTrackObject  

{  

    MyThreadData* pNext;  

    int nShortData;  

}; 


for (int i=0;i<10;i++)  

    {  

        <span style="color:#ff0000;">pData = new MyThreadData;</span>  

        pData->nShortData = i;  

        list.AddHead(pData);  

    }  

  

    //Traversing the list, releasing the space occupied by the MyThreadData object. < br / >
    pData = (MyThreadData*)list.GetHead();  

    while(pData != NULL)  

    {  

        MyThreadData* pNextData = pData->pNext;  

        printf("The value is %dn",pData->nShortData);  

        <span style="color:#ff0000;">delete pData;</span>  

        pData = pNextData;  

    }
