自己删除自己

当一个可执行程序exe在执行过程中，程序文件无法删除，这是因为系统将每个正在运行的程序对应的硬盘文件
映射到内存，即虚拟内存，要实现自删除，关键一点在程序退出前将程序从内存映射中解放出来，然后
再调用文件操作函数删除程序文件！

typedef int (WINAPI *PFClose)(LPVOID);
    OSVERSIONINFO os_info;
    os_info.dwOSVersionInfoSize=sizeof(os_info);
    LPVOID pBuffer=NULL;
    PFClose pClose,pDelete;
    char fn[4096];
    HINSTANCE hins=GetModuleHandle(NULL);// 得到本程序句柄
    GetModuleFileName(NULL,fn,4096);      // 得到本程序名称
    if(!GetVersionEx(&os_info))           // 得到当前Windows系统版本
       return FALSE;
   
    switch(os_info.dwPlatformId)
    {
           case VER_PLATFORM_WIN32_NT:    // 当前系统为WinNT平台系统
                __try
                {
                    while(CloseHandle((HANDLE)4));
                }
                __except(1)
                {    }
                CloseHandle((HANDLE)4);
                pClose=PFClose(UnmapViewOfFile);
                break;
           case VER_PLATFORM_WIN32_WINDOWS: // 当前系统为Win9X平台系统
                pClose=PFClose(FreeLibrary);
                break;
           default:
                return FALSE;
    }
    pDelete=PFClose(DeleteFile);
    pBuffer=VirtualAlloc(NULL,4096,MEM_COMMIT,PAGE_EXECUTE_READWRITE);   
    _asm
    {
        call _delete_end
    }
    _asm   // 尝试关闭并删除程序
    {
     _test_close:
         push hins
        call [pClose]   // 关闭程序
        or eax,eax
        jz _test_close
        lea eax,fn
         push eax
         call [pDelete] // 删除程序
         or eax,eax
         jz _Exit_Process
         call eax
     _Exit_Process: // 退出进程
        push 0
        push MEM_RELEASE
         push 0
         push pBuffer
         push ExitProcess // 退出进程
         push VirtualFree
         ret
    }
    _delete_end:     // 删除准备工作
    _asm   
    {
         pop ebx
         push 128
         push ebx
        push [pBuffer]
        call memcpy
         jmp pBuffer
    }

自己删除自己，没试过行不
