内存中栈的具体表现
棧在內(nèi)存中到底是如何表現(xiàn)的呢?我們來做一個實例調(diào)試一下。
?
代碼如下:
?
#include <stdio.h>
void main()
{
?_asm
?{
??push 0x12345678
??push 0x11112222?
??pop eax
??pop ebx
?}
}
?
按F9下一個斷點,然后按F5進(jìn)行調(diào)試。反匯編窗口如下
?
5:??????? _asm
6:??????? {
7:??????????? push 0x12345678
00401028?? push??????? 12345678h
8:??????????? push 0x11112222
0040102D?? push??????? 11112222h
9:??????????? pop eax
00401032?? pop???????? eax
10:?????????? pop ebx
00401033?? pop???????? ebx
11:?????? }
寄存器窗口如下:
?
EAX = CCCCCCCC EBX = 7FFDF000 ECX = 00000000 EDX = 00191030 ESI = 00000000
EDI = 0012FF48 EIP = 00401028 ESP = 0012FEFC EBP = 0012FF48 EFL = 00000202
?
EBP的地址是0012FF48,ESP的地址是0012FEFC,通過這兩個值就可以找到棧

0012FF52? 00 00 B8 0F 19 00 30 10 19 00? ......0...
?
然后按F11單步執(zhí)行,這時發(fā)現(xiàn)
?
EAX = CCCCCCCC EBX = 7FFDF000 ECX = 00000000 EDX = 00191030 ESI = 00000000 EDI = 0012FF48 EIP = 0040102D ESP = 0012FEF8 EBP = 0012FF48 EFL = 00000202
