TEComCachedDriveInfoIterator Class Reference

class TEComCachedDriveInfoIterator

Iterator which return only valid drives.

After instantiation, user must call either First() or Last() to set the initial position and check InRange() before calling the methods to access the drive number and attributes.

TBool

SetPos

(

const TInt

aDrive

)

Check if the drive is enabled for scanning and move index there if true.

Parameters

const TInt aDrive

the drive number of the drive to check.
