高手帮我分析用户堆栈

Funker · 发表于 2004-12-14 12:44:48

打印变量a以上的栈内容。
main()
{
      int a;
      printf("%p\n",&a);
      dump(&a,(int)(0xc0000000-(int)&a));
}

请高手看一下，bffff9dc到bffff20c和bffffa90到bffffb10.
打印的结果如下：

0xbffff9c4
      变量a    bp    返回值

怎么样才能对齐呢？

phyma · 发表于 2004-12-14 16:05:30

问题是什么？

Funker · 发表于 2004-12-14 16:14:12

对我打印的内容做分析啊。。。。。
