怎样得到当前指定硬盘的指定剩余空间？

GetDiskFreeSpaceEx()更好用一点support:win95os2

[howtotell]

struct _diskfree_t diskfree;
int nDrive = _getdrive();

while(_getdiskfree(nDrive, &diskfree)==0)
{
nDrive++;
}
nDrive--;
CString m_DiskSpace;
m_DiskSpace.Empty();

for(nDrive;nDrive>2;nDrive--)
{
CString mod;
CString mod2;
mod=nDrive-1 + _T('A');
mod2.Format("%s",mod);
// mod.Format("%s%s",mod,":\\");
mod+=":\\";
DWORD sector,byte,cluster,free;
long int freespace,totalspace;
GetDiskFreeSpace(mod,§or,&byte,&free,&cluster);
totalspace=(cluster)*(byte)*(sector)/1024/1024;
freespace=(free)*(byte)*(sector)/1024/1024;
CString diskspace;
diskspace.Format("%s%s%d%s%d%s",mod2," ",freespace,"/",totalspace,"MB \r\n");
m_DiskSpace+=diskspace;
//m_DiskSpace.Format("%s%s%s%d%s%d%s",m_DiskSpace,mod2," ",freespace,"/",totalspace,"MB \r\n");
}

BOOL GetDiskFreeSpace(

LPDWORD lpSectorsPerCluster, // sectors per cluster
LPDWORD lpBytesPerSector, // bytes per sector
LPDWORD lpNumberOfFreeClusters, // free clusters
