DriveIF

#GDrive - this represent a piece of hardware connected to the machine. It's generally only created for removable hardware or hardware with removable media.

#GDrive is a container class for #GVolume objects that stem from the same piece of media. As such, #GDrive abstracts a drive with (or without) removable media and provides operations for querying whether media is available, determining whether media change is automatically detected and ejecting the media.

If the #GDrive reports that media isn't automatically detected, one can poll for media; typically one should not do this periodically as a poll for media operation is potentially expensive and may spin up the drive creating noise.

#GDrive supports starting and stopping drives with authentication support for the former. This can be used to support a diverse set of use cases including connecting/disconnecting iSCSI devices, powering down external disk enclosures and starting/stopping multi-disk devices such as RAID devices. Note that the actual semantics and side-effects of starting/stopping a #GDrive may vary according to implementation. To choose the correct verbs in e.g. a file manager, use g_drive_get_start_stop_type().

For porting from GnomeVFS note that there is no equivalent of #GDrive in that API.

Functions

addOnChanged gulong addOnChanged(void delegate(DriveIF) dlg, ConnectFlags connectFlags): Emitted when the drive's state has changed.
addOnDisconnected gulong addOnDisconnected(void delegate(DriveIF) dlg, ConnectFlags connectFlags): This signal is emitted when the #GDrive have been disconnected. If the recipient is holding references to the object they should release them so the object can be finalized.
addOnEjectButton gulong addOnEjectButton(void delegate(DriveIF) dlg, ConnectFlags connectFlags): Emitted when the physical eject button (if any) of a drive has been pressed.
addOnStopButton gulong addOnStopButton(void delegate(DriveIF) dlg, ConnectFlags connectFlags): Emitted when the physical stop button (if any) of a drive has been pressed.
canEject bool canEject(): Checks if a drive can be ejected.
canPollForMedia bool canPollForMedia(): Checks if a drive can be polled for media changes.
canStart bool canStart(): Checks if a drive can be started.
canStartDegraded bool canStartDegraded(): Checks if a drive can be started degraded.
canStop bool canStop(): Checks if a drive can be stopped.
eject void eject(GMountUnmountFlags flags, Cancellable cancellable, GAsyncReadyCallback callback, void* userData): Asynchronously ejects a drive.
ejectFinish bool ejectFinish(AsyncResultIF result): Finishes ejecting a drive.
ejectWithOperation void ejectWithOperation(GMountUnmountFlags flags, MountOperation mountOperation, Cancellable cancellable, GAsyncReadyCallback callback, void* userData): Ejects a drive. This is an asynchronous operation, and is finished by calling g_drive_eject_with_operation_finish() with the @drive and #GAsyncResult data returned in the @callback.
ejectWithOperationFinish bool ejectWithOperationFinish(AsyncResultIF result): Finishes ejecting a drive. If any errors occurred during the operation, @error will be set to contain the errors and %FALSE will be returned.
enumerateIdentifiers string[] enumerateIdentifiers(): Gets the kinds of identifiers that @drive has. Use g_drive_get_identifier() to obtain the identifiers themselves.
getDriveStruct GDrive* getDriveStruct(bool transferOwnership): Get the main Gtk struct
getIcon IconIF getIcon(): Gets the icon for @drive.
getIdentifier string getIdentifier(string kind): Gets the identifier of the given kind for @drive. The only identifier currently available is #G_DRIVE_IDENTIFIER_KIND_UNIX_DEVICE.
getName string getName(): Gets the name of @drive.
getSortKey string getSortKey(): Gets the sort key for @drive, if any.
getStartStopType GDriveStartStopType getStartStopType(): Gets a hint about how a drive can be started/stopped.
getStruct void* getStruct(): the main Gtk struct as a void*
getSymbolicIcon IconIF getSymbolicIcon(): Gets the icon for @drive.
getVolumes ListG getVolumes(): Get a list of mountable volumes for @drive.
hasMedia bool hasMedia(): Checks if the @drive has media. Note that the OS may not be polling the drive for media changes; see g_drive_is_media_check_automatic() for more details.
hasVolumes bool hasVolumes(): Check if @drive has any mountable volumes.
isMediaCheckAutomatic bool isMediaCheckAutomatic(): Checks if @drive is capable of automatically detecting media changes.
isMediaRemovable bool isMediaRemovable(): Checks if the @drive supports removable media.
isRemovable bool isRemovable(): Checks if the #GDrive and/or its media is considered removable by the user. See g_drive_is_media_removable().
pollForMedia void pollForMedia(Cancellable cancellable, GAsyncReadyCallback callback, void* userData): Asynchronously polls @drive to see if media has been inserted or removed.
pollForMediaFinish bool pollForMediaFinish(AsyncResultIF result): Finishes an operation started with g_drive_poll_for_media() on a drive.
start void start(GDriveStartFlags flags, MountOperation mountOperation, Cancellable cancellable, GAsyncReadyCallback callback, void* userData): Asynchronously starts a drive.
startFinish bool startFinish(AsyncResultIF result): Finishes starting a drive.
stop void stop(GMountUnmountFlags flags, MountOperation mountOperation, Cancellable cancellable, GAsyncReadyCallback callback, void* userData): Asynchronously stops a drive.
stopFinish bool stopFinish(AsyncResultIF result): Finishes stopping a drive.
