请教一段经典汇编代码的解释

下面代码:
VC中嵌入汇编,实现了程序运行后自销毁程序的功能.我对Win32汇编不熟,麻烦高人解释一下.

#include "windows.h"
int main(int argc, char *argv[])
{
  char   buf[MAX_PATH];
  HMODULE module;
  module = GetModuleHandle(0);
  GetModuleFileName(module, buf, MAX_PATH);
  CloseHandle((HANDLE)4);
  __asm  
  {
    lea   eax, buf
    push   0
    push   0
    push   eax
    push   ExitProcess
    push   module
    push   DeleteFile
    push   UnmapViewOfFile
    ret
  }
  return 0;
}

操作                      堆栈
Push UnmapViewOfFile    Address of UnmapViewOfFile()
Push DeleteFile             Address of DeleteFile()
Push module             module
push ExitProcess             address of ExitProcess()
push eax                      offset buf
push 0                      0
push 0                      0


我自己的理解:当执行到ret之前,堆栈的情况如上面所示.当执行ret时,程序返回到了UnmapViewOfFile(),但是这个函数的参数是怎么传递进去的呢?

相关API:
BOOL UnmapViewOfFile(LPCVOID lpBaseAddress);
参数
  lpBaseAddress
  [in] Pointer to the base address of the mapped view of a file that is to be unmapped. This value must be identical to the value returned by a previous call to the MapViewOfFile or MapViewOfFileEx function.

等待中...

怎么没人说话呢？？help!

??晕 难道Address Of DeleteFile 成了UnmapViewOfFile 的参数不成？

继续等高人指点

"当然,UnmapViewOfFile 的参数不一定是Address Of DeleteFile ,而是这样:
"当前栈顶"+08,"当前栈顶"+0C之类的."


UnmapViewOfFile原型如下：
BOOL UnmapViewOfFile(LPCVOID lpBaseAddress);

那Address of DeleteFile() 就应该是UnmapViewOfFile的参数呀？？ 你为什么说"当前栈顶"+08,"当前栈顶"+0C之类的.

LPCVOID Pointer to a constant of any type.

不好意思 用词不当之处还望海涵

咱们共同提高！！
