const TUint KEntryAttNormal;

Description

File/directory attribute: any file without the hidden or system attribute.

const TUint KEntryAttReadOnly;

Description

File/directory attribute: read-only file or directory.

const TUint KEntryAttHidden;

const TUint KEntryAttRemote;

This file attribute bit is set if the file exists only on a remote file system and is not locally cached.

Due to the potential high-latency of remote file systems, applications (or users of applications) may make use of this bit to modify their behaviour when working with remote files.

This is a read-only attribute, so any attempt to set this attribute will will be ignored.

const TUint KEntryAttMaskFileSystemSpecific;

Description

The range of entry attributes reserved for file-system specific meanings. File systems may assign meaning to these bits, but their definition will not be supported nor maintained by Symbian.

All other file attribute bits are reserved for use by Symbian.

The following table summarises the assignment of attribute bits:

0 - KEntryAttReadOnly 1 - KEntryAttHidden 2 - KEntryAttSystem 3 - KEntryAttVolume

4 - KEntryAttDir 6 - KEntryAttArchive 7 - KEntryAttXIP

8 - KEntryAttRemote 9 - Reserved 10 - Reserved 11 - Reserved

12 - Reserved 13 - Reserved 14 - Reserved 15 - Reserved

const TUint KEntryAttMatchMask;

Description

Bit mask for matching file and directory entries.

This mask ensures that directories and hidden and system files are matched.

(Note that KEntryAttNormal matches all entry types except directories, hidden and system entries).

const TUint KEntryAttMaskSupported;

Description

Bit mask for matching file and directory entries.

This is used when all entry types, including hidden and system files, but excluding the volume entry are to be matched.

const TUint KEntryAttMatchExclusive;

Description

Bit mask for matching file and directory entries.

This is used for exclusive matching. When OR'ed with one or more file attribute constants, for example, KEntryAttNormal, it ensures that only the files with those attributes are matched. When OR’ed with KEntryAttDir, directories only (not hidden or system) are matched.

• KEntryAttDir
• KEntryAttNormal

const TUint KEntryAttMatchExclude;

Description

Bit mask for matching file and directory entries.

It is used to exclude files or directories with certain attributes from directory listings. This bitmask has the opposite effect to KEntryAttMatchExclusive. For example:

KEntryAttMatchExclude|KEntryAttReadOnly

excludes all read only entries from the directory listing.

KEntryAttMatchExclusive|KEntryAttReadOnly

lists only read only entries.
