DriveT

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 potententially 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.
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 capabable 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.
