A handle to a file server session.
A program or thread may have arbitrarily many sessions open simultaneously.
Use this class for all file system manipulation, including:
This class is not intended for user derivation.
The following restrictions apply when a path is specified:
| anonymous enum |
Special enumerator values for the SupportedFileSystemName() API.
| Enumerator | |
|---|---|
| KRootFileSystem | specifies "root" file system. The result will be the same as for FileSystemName() API call |
| KFirstChildFileSystem | specifies the first child file system number, the second will be KFirstChildFileSystem+1 etc. |
specifies drive finalisation modes
A set of special flags passed directly to the media driver via RFs::RemountDrive() API.
They are used to specify how exactly the drive should be remounted. For more information see RLocalDrive::ForceMediaChange()
| Enumerator | |
|---|---|
| KForceMediaChangeReOpenAllMediaDrivers | Passing this flag to RFs::RemountDrive() API results in all media drivers associated with the primary media being closed and reopened. All pending requests on all logical drives associated with the primary media will be cancelled. |
| KMediaRemountForceMediaChange | This flag is used to simulate ejecting and re-inserting the media. All pending requests on all logical drives associated with the primary media will be cancelled. |
| KForceMediaChangeReOpenMediaDriver | This flag is used to force the media driver for the specified logical drive to be closed and reopened. It should not affect any pending requests on other logical drives associated with the primary media. |
| EFSRV_IMPORT_C TInt RFs::AddCompositeMount | ( | const TDesC & | aFileSystemName, |
| TInt | aLocalDriveToMount, | ||
| TInt | aCompositeDrive, | ||
| TBool | aSync | ||
| ) | const |
Adds a local drive to the composite filesystem.
This can only be used before the composite filesystem is mounted. The local drive is mounted with the filesystem provided. If any local drive added is marked to be asynchronous, then the whole composite drive will be treated asynchronous.
| aFileSystemName | The filesystem of the local drive to be added. |
| aLocalDriveToMount | The local drive to be added. |
| aCompositeDrive | The drive the composite filesystem will be mounted on. |
| aSync | If the filesystem added here is preferred to be synchronous. |

| EFSRV_IMPORT_C TInt RFs::CheckDisk | ( | const TDesC & | aDrive | ) | const |
Checks the integrity of the File System mounted on the specified drive.
The behaviour of this API and return codes are File System specific, dependent on how the File System implements its CheckDisk functionality. Note that CheckDisk does not fix any errors that may be found, it just reports the first problem it has found.
CheckDisk checks for a limited amount of possible corruption cases such as invalid cluster numbers in the FAT table, lost and cross-linked cluster chains, various errors within the directory entry etc.
If CheckDisk returns KErrNone, this means that there are no errors that CheckDisk on FAT is aware of.
Error codes returned by the FAT version of CheckDisk include: 1 Bad cluster value in FAT table detected. 2 Cross-linked cluster chain detected. 3 Lost cluster chain detected. 4 File size does not correspond to the number of clusters reported in the FAT table.
| aDrive | Path containing the drive to be checked. If the drive letter is not specified, the current session drive is taken by default. |

Connects a client to the file server.
To end the file server session, use Close().
| aMessageSlots | The number of message slots required. The default value of KFileServerDefaultMessageSlots indicates that message slots will be acquired dynamically from the system wide pool. Override this value with a fixed number, if a fixed number of slots are to be allocated to the session. If overriding, note that the number of message slots represents the number of operations, such as reads and writes, that can be outstanding at once; always remember to provide a spare slot for the cancel operation. |

This function queries the sub type of the file system mounted on the specified volume.
For example, 'FAT16' of the Fat file system. TFSName is recommended as the type for aName when using this function.
NOTE: For the file systems without a sub type (e.g. ROM file system), the the file system name is returned (For example, 'Rom'). Examples: "FAT" file system; the subtypes can be "fat12", "fat16" or "fat32" "ROFS" file system; the subtype will be "ROFS"
Note also that the file system name, returned in the aName descriptor shall be threated as case-insensitive string. I.e. "fileSystem" and "FILESYSTEM" mean absolutely the same. Therefore, case-insensitive string methods (like TDesC::FindF(), TDesC::CompareF()) shall be used to deal with the names.

The following restrictions apply to the path and to its components:
| aFileName | The path to be checked for validity. May specify a filename alone, or an entire path specification, including drive letter. If a path is specified, all components are checked for validity. |
| aBadChar | reference to the variable that on return can contain illegal character from aFileName. 1. if the filename and optional path in aFileName are valid, this method will return ETrue and aBadChar will be set to 0x00. 2. if there is an illegal character in aFileName, this method will return EFalse and aBadChar will contain this illegal character. 3. if there is no illegal characters in aFileName, but this is still not a valid filename (like "\\SomeName\\") this method will return EFalse and aBadChar will contain space ' ' or code 0x20. |

| EFSRV_IMPORT_C TBool RFs::IsValidName | ( | const TDesC & | aName, |
| TNameValidParam & | aParam | ||
| ) |
This API can be used to validate both directory and file names.
If the name ends with a trailing backslash '\' then it is considered to be a directory else a filename. For example: "C:\\test\\" would mean a directory, whereas "C:\\test" would mean a file, both of which would be returned as a Valid Name. However a name such as "C:\\test\\\\" would be returned as an Invalid name with error code TError::ErrBadName
The following restrictions apply to the path and to its components:
| aName | The path to be checked for validity. May specify a name alone, or an entire path specification, including drive letter. If a path is specified, all components are checked for validity. |
| aParam | reference to the variable that on return can contain details of the error if any. While constructing an object of this type one could specify whether one wants to use the sessionPath for filling up missing parts of aName, or one would want to test aName as it is without prepending the sessionPath. By default the sessionPath is NOT used. 1. if the name and optional path in aName are valid, this method will return ETrue and TError::iError will contain ErrNone. 2. if there is an illegal character in aName, this method will return EFalse and TError::iError will contain KErrBadCharacter. Also TError::iInvalidCharPos will indicate the position of the rightmost invalid character. 3. if there is no illegal characters in aName, but this is still not a valid name (like "") this method will return EFalse and TError::iError will contain KErrBadCharacter, while iInvalidCharPos will be set to 0 4. if length of the name exceeds 256 characters, this method will return EFalse and TError::iError will contain KErrTooLong. if the optional sessionPath is used, then the length of the sessionPath is also used to determine whether the length exceeds 256 characters. |

Sets the password for the media in the specified drive.
The media is not necessarily locked afterwards. Accessibility is determined by the following rules:
| aDrv | The drive. |

| EFSRV_IMPORT_C TInt RFs::MkDir | ( | const TDesC & | aPath | ) |
Makes a directory.
It should be a sub-directory of an existing directory and its name should be unique within its parent directory, otherwise the function returns error code KErrAlreadyExists.
Note that if a filename is specified in the argument, it is ignored. Therefore, there should be a trailing backslash after the final directory name in the argument to indicate that it is a directory, not a filename.
For example, following code will create directory "C:\\DIR1\\"
The last line in the following example will result in KErrAlreadyExists because "DIR2" doesn't have a trailing backslash, therefore is considered as a file name and discarded. Directory "C:\\DIR1\\" has already been created.
This example will always fail because "DIR1" doesn't have a trailing backslash and discarded while the root directory always exists.
Note, the following case
But if there is a file named "example.txt", which exists at the same location, KErrAccessDenied is returned.
Note also that because this method can return an error code (eg. because the disk is full) before checking whether the path already exists, it is not appropriate to use it just to work out whether a path exists or not.
See MkDirAll(), which may also create intermediate directories.
| aPath | The name of the new directory. Any path components which are not specified here will be taken from the session path. The directory name shall not contain wild cards ('?' or '*' characters) and illegal characters like '<', '>', ':', '"', '/', '|' and ''. The directory name containing only whilte space characters (See TChar::IsSpace()) is also illegal. |

| EFSRV_IMPORT_C TInt RFs::MkDirAll | ( | const TDesC & | aPath | ) |
Makes one or more directories.
Any valid path component specified in aPath which does not already exist is created as a directory.
Note that if a filename is specified in the argument, it is ignored. Therefore, there should be a trailing backslash after the final directory name in the argument to indicate that it is a directory, not a filename.
See also notes on RFs::MkDir() about trailing backslashes in directory names.
Note also that because this method can return an error code (eg. because the disk is full) before checking whether the path already exists, it is not appropriate to use it just to work out whether a path exists or not.
See MkDir(), which creates only a single new directory.
| aPath | The path name specifiying the directory or directories to create. If the function completes successfully, this path identifies a valid directory. Any path components which are not specified here are taken from the session path. |

| EFSRV_IMPORT_C void RFs::NotifyChange | ( | TNotifyType | aType, |

Requests a notification of change to files or directories.
Changes are notified either:
or
Such notification is useful for programs that maintain displays of file lists which must be dynamically updated. The alternative is to do no updating, or to perform periodic monitoring for change, which is inefficient.
This is an asynchronous request and, as such, results in precisely one signal to the request status passed as a parameter. To avoid missing any change, this request should be issued before the first file list is constructed. When the request completes, a new request should be issued before the next file list is constructed. When the file server session is closed, this request is implicitly cancelled.
Call NotifyChangeCancel() to explicitly cancel a notification request.
| aType | Indicates the kind of change that should result in notification. For example: ENotifyEntry causes notification only when an entry is added or deleted, or when a disk is formatted or changed; ENotifyAll causes notification following any type of change, such as when a file is written to, or when a file's attributes are changed. |
| aStat | The request status. This is set to KErrNone on completion, otherwise one of the other system-wide error codes. |

The threshold is crossed if free disk space increases to a value above the threshold value or decreases to a value below the threshold value.
This is an asynchronous request that completes if any of the following events occur:
Note that free disk space notification is not supported for drives using remote file systems.
TDriveNumber
| aThreshold | The threshold value. This must be greater than zero and less than the total size of the disk. |
| aDrive | The drive number. This is an explicit drive defined by one of the TDriveNumber enum values or the value KDefaultDrive. If KDefaultDrive is specified, then the drive monitored is the session path drive. |
| aStat | The request status object. On request completion, contains: KErrNone, if the threshold value is crossed, if any drive is formatted, if there is a media change on any socket, if there is a power up or if the scandrive utility is run on any drive; KErrCancel, if the outstanding request is cancelled by a call to NotifyDiskSpaceCancel(); KErrArgument, if the threshold value is outside its limits. |

| TNotifyDismountMode | aMode = EFsDismountRegisterClient |

| ) | const |
Controls file system dismounting on the specified drive, the way of control depends on the parameter TNotifyDismountMode.
This API allows interested parties to: 1. Subscribe for notification of file system dismounting events. This allows subscribers to commit their data to the media prior to the file system being dismounted. See TNotifyDismountMode::EFsDismountRegisterClient
If there are clamped files on the volume, the file system dismounting will not happen until these files are unclamped.
The use case scenario: A 'Master' application that wants to dismount the file system on some drive 'aDrive' 'Client1' and 'Client2' applications interested in file system dismount event notifications, because they need to commit their data before the file system is dismounted.
If, for example, 'Client2' hasn't responded in a reasonable time by calling RFs::AllowDismount(), the 'Master' can cancel the pending 'aStat' and dismount the file system by force by calling this API with EFsDismountForceDismount. In this case all subsequent attempts by 'Client2' to use its opened handles will result in KErrDismounted; these handles should be closed.

| const TDesC & | aNewName | ||
| ) |
Renames a single file or directory.
It can also be used to move a file or directory by specifying different destination and source directories. If so, the destination and source directories must be on the same drive. If a directory is moved, then the directory structure beneath it is also moved.
If a directory specified by aNewName is different from one specified by anOldName, then the file or directory is moved to the new directory. The file or directory cannot be moved to another device by this means, either explicitly (by another drive specified in the name) or implicitly (because the directory has been mapped to another device with SetSubst().
The function fails and returns an error code in the following circumstances:
Read-only, system and hidden files may be renamed. The renamed file's attributes are preserved.
Note that when this function is operating on directories, a trailing backslash is not required after the final directory name in either anOldName or aNewName.
See class CFileMan for information on renaming multiple files.
| anOldName | File or directory to be renamed. Any path components which are not specified here will be taken from the session path. |
| aNewName | Path specifying the new name for the file or directory and/or its new parent directory. All directories specified in this path must exist. Any path components which are not specified here will be taken from the session path. |

| EFSRV_IMPORT_C TInt RFs::Replace | ( | const TDesC & | anOldName, |
| const TDesC & | aNewName | ||
| ) |
Replaces a single file with another.
This function does not support the use of wildcards. Unlike Rename(), it only applies to files.
This function operates as follows:
anOldName may be hidden, read-only or a system file. However, neither anOldName, nor, if it exists, aNewName, can be open; aNewName must not be read-only. Both files must be on the same drive.
| anOldName | The file to be replaced. Must exist and must be closed. It is deleted by this function. |
| aNewName | The file to replace anOldName. Does not need to exist, but if it does exist, it must be closed. If it exists, its name remains unchanged but its contents, attributes and the date and time of its last modification are replaced by those of anOldName. If it does not exist, it will be created and is assigned the contents and attributes of anOldName. Must not be followed by a trailing backslash. |

| EFSRV_IMPORT_C TInt RFs::ReserveDriveSpace | ( | TInt | aDriveNo, |
| TInt | aSpace | ||
| ) |
Reserves an area of a drive.
It is intended that sensible (tm) apps will reserve a small area of disk for 'emergency' use in case of later out of disk situations. If the amount of reserved space later needs to be readjusted, this method should be called again with aSpace as the amount of extra space needed.
Once space has been reserved via this method, an application can use RFs::GetReserveAccess to gain access to the reserved area prior to executing disk space critical sections of code. After the section of code is complete, the application should release access to the reserved area.
For internal drives, reserved space will be lost if a reboot occurs. For removeable drives, reserved space may be lost if there is a media change.
Reserved space will be cleaned up automatically when the RFs is closed.
Each drive has a max amount of space available to be reserved, and individual sessions also have a max amount of space. These are defined in f32/sfile/sf_std.h as KMaxTotalDriveReserved and KMaxSessionDriveReserved respectively. Once space is reserved, it is only available to the reserving session until that session releases the reserved space.
| aDriveNo | Which drive to reserve space on |
| aSpace | Amount of space to reserve |

| EFSRV_IMPORT_C TInt RFs::ResourceCount | ( | ) | const |
Gets the number of currently open resources.
The resource count is incremented by one: when a file or directory is opened, when a device is opened in preparation for formatting, when a direct access channel to a disk is opened.
(generated from Symbian Developer Library)
| EFSRV_IMPORT_C void RFs::ResourceCountMarkEnd | ( | ) | const |
Ends resource count checking.
Typically, this function is called immediately before closing a session with the file server.
Panic condition: CSessionFs 2 if the number of resources opened since the start of resource count checking is not equal to the number of resources closed.
(generated from Symbian Developer Library)
| EFSRV_IMPORT_C void RFs::ResourceCountMarkStart | ( | ) | const |
Marks the start of resource count checking.
Typically, this function is called immediately after a client is connected to the file server, and before any resources are opened.

| EFSRV_IMPORT_C TInt RFs::RmDir | ( | const TDesC & | aPath | ) |
Removes a directory.
The directory must be empty and cannot be the root directory.
Note that if a filename is specified in the argument, it is ignored.
For example, following code will result in directory "C:\\SRC\\" being removed as long as it is empty, the existance of "ENTRY" will not be checked:
Therefore, there should be a trailing backslash after the final directory name in the argument to indicate that it is a directory, not a filename.
See class CFileMan for information on deleting a non-empty directory and all of its contents.
| aPath | The path name of the directory to be removed. Any path components which are not specified here are taken from the session path. Only the lowest-level directory identified is removed. |
(generated from Symbian Developer Library)
| EFSRV_IMPORT_C TInt RFs::ScanDrive | ( | const TDesC & | aDrive | ) | const |
Checks the integrity of the File System mounted on the specified drive and attempts to correct some known File System errors.
The behaviour of this API and return codes are File System specific, dependent on how the File System implements its ScanDrive functionality.
ScanDrive will not run on drives that have files or directories opened.
ScanDrive is intended to be run ONLY on "Rugged-FAT" file system which is applicable to internal non-removable drives. Internal RAM drives are not supported.
The "Rugged FAT" file system is designed in such a way that only a limited number of known cases of corruption can be caused by sudden power loss. All of these known cases can be corrected by ScanDrive. Hence, running ScanDrive on "Rugged FAT" file system will result in: KErrNone If there was no File System corruption or ScanDrive has successfully repaired the File System. KErrCorrupt If ScanDrive has found a File System error that it cannot repair. Other system-wide error codes, see above.
Running ScanDrive on removable media or media that has FAT file system not in "Rugged FAT" mode is not practical, because ScanDrive is not designed for this. Therefore, do not treat ScanDrive on removable media as a generic "disk repair utility".
| aDrive | Path indicating the drive which contains the disk to be checked. If the drive letter is not specified, the current session drive is taken by default. |

| EFSRV_IMPORT_C TInt RFs::SessionPath | ( | TDes & | aPath | ) | const |
Gets the session path.
When a client connects to the file server, its session path is initialised to the system default path. The session path of an existing client can only be changed by this function.
| aPath | On return, contains the session path, including a trailing backslash. |
(generated from Symbian Developer Library)
| EFSRV_IMPORT_C TInt RFs::SetAllocFailure | ( | TInt | aAllocNum | ) |
Fails an allocation after aAllocNum successes.
This function can only be used in debug builds or if _DEBUG or _DEBUG_RELEASE is defined. In release build, this method is not implemented and it always returns KErrNotSupported.
| aAllocNum | Count after which allocation failure is expected. |

| EFSRV_IMPORT_C TInt RFs::SetAtt | ( | const TDesC & | aName, |
| TUint | aSetAttMask, | ||
| TUint | aClearAttMask | ||
| ) |
Sets or clears the attributes of a single file or directory.
The function uses two bitmasks. The first bitmask specifies the attributes to be set; the second specifies the attributes to be cleared.
An attempt to set or clear the KEntryAttDir, KEntryAttVolume or KEntryAttRemote attributes have no effect.
| aName | File or directory name. Any path components which are not specified here will be taken from the session path. Must not include wildcard characters. The file must be closed. |
| aSetAttMask | Bitmask indicating the attributes to be set. |

| const TTime & | aTime, | ||
| TUint | aSetAttMask, | ||
| TUint | aClearAttMask | ||
| ) |
Sets both the attributes and the last modified date and time for a file or directory.
The function uses two bitmasks. The first bitmask determines which attributes should be set. The second bitmask determines which should be cleared.
An attempt to set or clear the KEntryAttDir, KEntryAttVolume or KEntryAttRemote attributes have no effect.
| aName | File or directory name. |
| aTime | New date and time. UTC date and time should be used. |
| aSetAttMask | Bitmask indicating which attributes are to be set. |

| EFSRV_IMPORT_C TInt RFs::SetNotifyChange | ( | TBool | aNotifyChange | ) |
Enables/Disables change notification on a per-session basis.
Change notification is enabled by default, and can be disabled using this API. Disabling change notification will result in clients of the file server not being notified of events such as directory/file changes.
| aNotifyChange | ETrue to enable change notifications, EFalse to disable. |
(generated from Symbian Developer Library)
| EFSRV_IMPORT_C void RFs::SetNotifyUser | ( | TBool | aValue | ) |

Note that if some drive is mounted as synchronous (see RFs::MountFileSystem), the user won't be notified about read/write failures on it.
| aValue | ETrue, if user is to be notified of read or write failures; EFalse, for no notification. |
(generated from Symbian Developer Library)
| EFSRV_IMPORT_C TInt RFs::SetSessionPath | ( | const TDesC & | aPath | ) |
Sets the session path for the current file server client.
When the client first connects to the file server, its session path is initialised to the system default path.
Note that the session path is text-only. It does not cause any locking. Thus, although the path must be syntactically correct, its components do not need to be valid at the time the path is set, and any component may be deleted, removed or unmounted while the path is set.
| aPath | The new session path. Consists of a drive and path. Normally, a drive should be specified, but if not, the drive specified in the existing session path is preserved. If a file is specified, then the function fails and returns an error code. Therefore, the final component in the path must have a trailing backslash to indicate that it is a directory. All components of the path must be syntactically correct, for example, wildcard characters and double backslashes are not allowed in any part of it. |
(generated from Symbian Developer Library)
| EFSRV_IMPORT_C TInt RFs::SetSessionToPrivate | ( | TInt | aDrive | ) |
Sets the session path to point to the private path on the specified drive.
The private directory does not need to exist at this point.
The private path for a process has the form: \Private\13579BDF\ where 13579BDF is the identity of the process.
| aDrive | The drive for which information is requested. Specify a drive in the range EDriveA to EDriveZ for drives A to Z respectively. |

| EFSRV_IMPORT_C TInt RFs::SetSubst | ( | const TDesC & | aPath, |
| TInt | aDrive = KDefaultDrive |
||
| ) |
Assigns a path to a drive letter.
Whenever that drive letter is used, it will be translated into a reference to the path specified here. To clear a drive substitution, specify an empty descriptor for aPath.
Note that the substituted path is text-only. Its components need not be syntactically correct, nor must they be valid at the time the substitution is set. Any component may be deleted, removed or unmounted while the substitution is set.
| aPath | The path to be assigned to the drive letter. If a drive letter is specified in the path, it must not itself be substituted or redirected, or the function will return an error. If no drive is specified, the drive contained in the default session path is used, and if no path is specified, the default session path is used. If a filename or extension is included in the path, the function will return an error. Therefore, the final component in the path must have a trailing backslash to indicate that it is a directory. |
| aDrive | The drive to which a path is to be assigned. Specify a number in the range 0 (EDriveA) to 25 (EDriveZ) for drives A to Z. Must not be local, ROM, or redirected, otherwise an error is returned. May be substituted, but only if the function is being used to clear the substitution. If the same drive is specified in the path, the function will return an error. The default drive is the session default drive KDefaultDrive. |

| EFSRV_IMPORT_C TInt RFs::SupportedFileSystemName | ( | TDes & | aName, |
| TInt | aDrive, | ||
| TInt | aFsEnumerator | ||
| ) | const |
Get one of the supported file system names on a specified drive.
This API can be used for enumerating file systems that can be recognised and mounted automatically, without user's interaction. If the automatic recognition and mountng some known file systems is supported on the specified drive, there shall be at least 2 names in the list. For example "FAT" and "exFAT". If "automatic file system recognising" feature is not supported, the list will consist of just one name, and this will be the name returned by RFs::FileSystemName() API.
Note that the file system name, returned in the aName descriptor shall be threated as case-insensitive string. I.e. "fileSystem" and "FILESYSTEM" mean absolutely the same. Therefore, case-insensitive string methods (like TDesC::FindF(), TDesC::CompareF()) shall be used to deal with the names.
FileSystemName() KRootFileSystem
| aName | On successful return, contains the name of the file system that correspond to the aFsEnumerator value. m |
| aDrive | The drive number |
| aFsEnumerator | The supported file system enumerator. can be: KRootFileSystem a special value; in this case the returned name will be the same as obtained by FileSystemName() 0,1,2... integer values specifying the sequential number of supported filesystem. See the return error code. |

| TRequestStatus & | aStat | ||
| ) | const |
Gets volume information for a formatted device asynchronously.
TInt RFs::Volume(TVolumeInfo& aVol,TInt aDrive) for the synchronous version."Asynchronously" corresponds to the amount of free space on the volume in TVolumeInfo::iFree. I.e. this function returns the current amount of free space on the volume, which can be changing due to some filesystems' activities. For example, some filesystems can be performing free space calculations in the background. Comparing to the RFs::Volume(TVolumeInfo& aVol,TInt aDrive), this method doesn't block the client until background filesystem activity finishes, which can be useful in some situations.
| aVol | On return, contains the volume information with the current value in the TVolumeInfo::iFree. |
| aDrive | Drive number to query. Specify a drive in the range EDriveA to EDriveZ for drives A to Z respectively. |
| aStat | request status. At present is used just for indication of the asynchronous version and gets immediately completed, so there is no reason to analyse its value. |

Gets volume information for a formatted device.
This function provides additional information to that given by Drive(), including the volume label, if set, and the amount of free space on the disk.
Note, use Drive() to get information about the drive without reference to a volume. These two functions are separate because, while the characteristics of a drive cannot change, those of a volume can, by mounting different media, reformatting etc. A volume may not even be present if the media is removable.
| aVol | On return, contains the volume information. |
| aDrive | The drive which contains the media for which volume information is to be displayed. Specify a drive in the range EDriveA to EDriveZ for drives A to Z respectively. The default drive is the session default drive KDefaultDrive. |
