Code snippet

The drive list consists of an array of 26 bytes. Array index 0 corresponds to drive A, 1 equals B etc. The array member value is a bitmap of drive attributes, or 0 if there is no such drive. The following code prints each drive in the drive list as a letter, followed by the hex value of the integer indicating the drive's attributes.

#include <f32file.h>

TDriveList drivelist;
TChar driveLetter; TInt driveNumber=EDriveA; 
_LIT(KDrive,"%c: %02x ");
User::LeaveIfError(fsSession.DriveList(drivelist)); 
 
for(;driveNumber<=EDriveZ;driveNumber++) 
{ 
   if (drivelist[driveNumber]) 
   {
     User::LeaveIfError(fsSession.DriveToChar(driveNumber,driveLetter));
     console->Printf(KDrive, TUint(driveLetter), drivelist[driveNumber]); 
   }
}
