-// CRsfwFsDirCB::ReadL
-// File Server calls this function to retrieve one entry from open directory
-// (next unread). When the last entry has been read, the function leaves with
-// User::Leave(KErrEof). All of the properties of a TEntry, other than the UID
-// types, are always read. The time stored in the iModified member of anEntry
-// should be converted from UTC time to local time. When storing the iName
-// member of anEntry, the current (.), or parent marker (..) in the directory
-// should not be returned.
-//
-// If the KEntryAttAllowUid flag is set in the iAtt member of anEntry, then
-// the entry UID type of an entry will be read. If, on reading the UID from
-// a file, KErrCorrupt is generated, because the file is corrupt,
-// ReadL() should not leave with this error message, but should return
-// as normal.
-//
-// FILTERING:
-// The function should read successive entries until a suitable entry is found.
-// An entry is suitable if the entry attributes match the criteria set by this
-// object's attributes, which are set on initialisation. The File Server has
-// set CDirCB::iAtt (which we inherit) with the bitmask.
-//
-// The File Server opened the directory with a name mask (e.g. "*").
-// This mask has been to stored to iMask of this class. We must only return entries,
-// whose name match this mask.
-//
-// If, on return, the entry's full file name, TEntry::iName, is longer than
-// the maximum buffer size, then the entry cannot be returned to the client.
-// In this case the file server will set iPending to true and will call
-// StoreLongEntryName() before calling this function again.
-// In this case (when iPending is true), the function should re-read
-// the last entry to be read; it should also set iPending to false and
-// should not advance the current read position.
-//
-// (other items were commented in a header).
