高级语言反汇编程序的函数调用过程

h                ;esp减少一个值,空出一段存储区
00402036   push        ebx                    ;将三个寄存器的值入栈,以便在函数中使用它
00402037   push        esi                    ;
00402038   push        edi                    ;
00402039   lea         edi,[ebp-44h]          ;
0040203C   mov         ecx,11h                ;
00402041   mov         eax,0CCCCCCCCh         ;
00402046   rep stos    dword ptr [edi]        ;
127:      int* q = (int*)p;                   ;
00402048   mov         eax,dword ptr [ebp+8]  ;ebp+8指向函数输入参数的最低位地址;
;如果是ebp+4则指向函数返回地址00401FC1的最低位,值为C1
0040204B   mov         dword ptr [ebp-4],eax  ;
128:      return 0;                           ;
0040204E   xor         eax,eax                ;返回值放入eax寄存器中
129:  }
00402050   pop         edi                    ;三个寄存器出栈
00402051   pop         esi                    ;
00402052   pop         ebx                    ;
00402053   mov
