C++浅析——虚表和虚表Hook

为了探究虚表的今生前世，先来一段测试代码

虚函数类：

 1 class    CTest
 2 {
 3 public:
 4     int        m_nData;
 5 
 6     virtual    void    PrintData()
 7     {
 8         printf("Data = 0x%x\n", m_nData);
 9     }
10 };
11 
12 
13 class    CBase1
14 {
15 public:
16     int        m_nData;
17 
18     virtual    void PrintData1() = 0;
19 };
20 
21 
22 class    CBase2
23 {
24 public:
25     int        m_nData;
26 
27     virtual    void PrintData2() = 0;
28 };
29 
30 class    CBaseTest : public CBase1, public CBase2
31 {
32 public:
33     void    PrintData1()
34     {
35         printf("Data = 0x%x\n", CBase1::m_nData);
