获取C++类成员虚函数地址

class Base{
    int i;
public:
    virtual void f1(){
        cout<<"Base's f1()"<<endl;
    }
};

Base b;
void (Base::*mfp)() = &Base::f1;
printf("address: %p", (void*)(b->*mfp));

#define ShowFuncAddress(function) _asm{\
    mov eax, function}\
    _asm{mov p,eax}\
    cout<<"Address of "#function": "<<p<<endl;

//使用示例
ShowFuncAddress(Base::f1);

/**********************
@className:类名称
@pObj:类对象地址
@index:虚函数表项（从0开始）
**********************/
void showVtableContent(char* className, void* pObj, int index){
    unsigned long* pAddr=NULL;
    pAddr=reinterpret_cast<unsigned long*>(pObj);
    pAddr=(unsigned long*)*pAddr;     //获取虚函数表指针
    cout<<className<<"'s vtable["<<index<<"]";
    cout<<": 0x"<<(void*)pAddr[index]<<endl;
}

//使用示例：
class Base{
    int i;
public:
    virtual void f1(){
        cout<<"Base's f1()"<<endl;
    }
    virtual void f2(){
        cout<<"Base's f2()"<<endl;
    }
};

Base b;
showVtableContent("Base",&b,0);  //输出第一个虚函数Base::f1的地址
showVtableContent("Base",&b,1);  //输出第二个虚函数Base::f2的地址
