windows下的api磁盘的读写

要有windows.h文件。文件能运行 必须有creatfile devicectrlo readfile writefile
point 要源代码。希望大神帮忙

Windwos 下是不允许直接操作硬件的，但可以通过 IOCTRL 来控制驱动实现对硬件的操作。
你是想要通过 IOCTRL 函数来直接对磁盘进行读写吗？如果是，则不仅仅需要这些 API 函数，还需要驱动的支持。

不知道你的目的是什么，要达到什么效果，它有一些标准的 IO

void CReadSectorDlg::OnReadButton()
{
UpdateData (TRUE) ;
CFile m_Sector_file ;
char * buffer ;

if ( m_FileName_str == "") 
{
    MessageBox ("Please enter a file to which the read sector contents are to be stored !!");
    return ;
}

m_Sector_file.Open (m_FileName_str, CFile::modeCreate | CFile::modeWrite  , NULL ) ;
buffer = (char*) malloc (512 * m_NumSec_int) ;

buffer = ReadSectors (m_Head_int, m_Track_int, m_Sector_int, m_NumSec_int);
if ( buffer == NULL ) 
{
    MessageBox ("Operation Failed -- !!");
    return ;
}
m_Sector_file.Write (buffer, 512*m_NumSec_int) ;
m_Sector_file.Close ();

MessageBox ("Operation Complete !","ReadSectors",  MB_ICONINFORMATION );

}

char * CReadSectorDlg::ReadSectors(int head, int track, int sector, int numsec)

看上去就是不要使用windows 文件API，比如CFile等来读写文件，而是通过DeviceControl，WriteFile这些来读写

w哦不知道怎么安装需要的驱动
