Constructor & Destructor Documentation

Dir ( )

Create an uninitialized directory.

Must call open to initialize the directory on a file system

Dir	(	FileSystem *	fs,
		const char *	path
	)

Open a directory on a filesystem.

Parameters

fs	Filesystem as target for a directory
path	Name of the directory to open

virtual ~Dir ( )

virtual

Destroy a file.

Closes file if the file is still open

Member Function Documentation

virtual int close ( )

virtual

Close a directory.

Returns: 0 on success, negative error code on failure

Implements DirHandle.

virtual int closedir ( )

virtualinherited

Closes the directory.

Returns: 0 on success, -1 on error.

Deprecated:: Replaced by `int DirHandle::close()'

Definition at line 117 of file DirHandle.h.

virtual int open	(	FileSystem *	fs,
		const char *	path
	)

virtual

Open a directory on the filesystem.

Parameters

fs	Filesystem as target for a directory
path	Name of the directory to open

Returns: 0 on success, negative error code on failure

virtual ssize_t read ( struct dirent * ent )

virtual

Read the next directory entry.

Parameters

ent	The directory entry to fill out

Returns: 1 on reading a filename, 0 at end of directory, negative error on failure

Implements DirHandle.

virtual struct dirent* readdir ( )

virtualinherited

Returns the directory entry at the current position, and advances the position to the next entry.

Returns: A pointer to a dirent structure representing the directory entry at the current position, or NULL on reaching end of directory or error.

Deprecated:: Replaced by `ssize_t DirHandle::read(struct dirent *ent)

Definition at line 132 of file DirHandle.h.

virtual void rewind ( )

virtual

Rewind the current position to the beginning of the directory.

Implements DirHandle.

virtual void rewinddir ( )

virtualinherited

Resets the position to the beginning of the directory.

Deprecated:: Replaced by `void DirHandle::rewind()'

Definition at line 142 of file DirHandle.h.

virtual void seek ( off_t offset )

virtual

Set the current position of the directory.

Parameters

offset Offset of the location to seek to, must be a value returned from tell

Implements DirHandle.

virtual void seekdir ( off_t location )

virtualinherited

Sets the position of the DirHandle.

Parameters

location The location to seek to. Must be a value returned by telldir.

Deprecated:: Replaced by `void DirHandle::seek(off_t offset)'

Definition at line 166 of file DirHandle.h.

virtual size_t size ( )

virtual

Get the sizeof the directory.

Returns: Number of files in the directory

Reimplemented from DirHandle.

virtual off_t tell ( )

virtual

Get the current position of the directory.

Returns: Position of the directory that can be passed to rewind

Implements DirHandle.

virtual off_t telldir ( )

virtualinherited

Returns the current position of the DirHandle.

Returns: the current position, -1 on error.

Deprecated:: Replaced by `off_t DirHandle::tell()'

Definition at line 155 of file DirHandle.h.
