本文实例讲述了C++采用ring3读取MBR的方法,分享给大家供大家参考。具体实现方法如下:
\\\\\\\\.\\\\PhysicalDrive0\", GENERIC_READ, FILE_SHARE_READ | FILE_SHARE_WRITE, NULL, OPEN_EXISTING, 0, NULL);
if(hDevice == INVALID_HANDLE_VALUE)
{
printf(\"\\nFailed - CreateFile - Open the PhysicalDrive0.\\n\");
return 0;
}
bRet = ReadFile(hDevice, (LPVOID)bytBuffer_1, 512, &dwBytesReturned, NULL);
if(bRet == FALSE)
{
printf(\"\\nFailed - ReadFile - the first one.\\n\");
return 0;
}
printf(\"aaaa\");
Sleep(1000*3);
printf(\"\\nRead MBR using the ReadFile function...\\n\");
printf(\"- - - - - - - - - - - - - - - - - - - - - - - - - - - -\");
sprintf(string, \"\\n\");
for(DWORD i = 0; i < 512; i++)
{
sprintf(string, \"%s %02X\", string, bytBuffer_1[i]);
if(((i + 1) % 16) == 0)
sprintf(string, \"%s\\n\", string);
if(((i + 1) % 16) == 8)
sprintf(string, \"%s -\", string);
}
printf(\"%s\", string);
printf(\"- - - - - - - - - - - - - - - - - - - - - - - - - - - -\");
打印结果如下:
希望本文所述对大家的C++程序设计有所帮助。
