Description

The Mount interface represents user-visible mounts. Note, when porting from GnomeVFS, Mount is the moral equivalent of GnomeVFSVolume.

Mount is a "mounted" filesystem that you can access. Mounted is in quotes because it's not the same as a unix mount, it might be a gvfs mount, but you can still access the files on it if you use GIO. Might or might not be related to a volume object.

Unmounting a Mount instance is an asynchronous operation. For more information about asynchronous operations, see AsyncResult and Task. To unmount a Mount instance, first call mountUnmountWithOperation with (at least) the Mount instance and a AsyncReadyCallback. The callback will be fired when the operation has resolved (either with success or failure), and a AsyncResult structure will be passed to the callback. That callback should then call mountUnmountWithOperationFinish with the Mount and the AsyncResult data to see if the operation was completed successfully. If an error is present when mountUnmountWithOperationFinish is called, then it will be filled with any error information.

-> Maybe b	`cancellable`: optional `Cancellable` object, `Nothing` to ignore
-> Maybe AsyncReadyCallback	`callback`: a `AsyncReadyCallback`
-> m ()

Tries to guess the type of content stored on mount. Returns one or more textual identifiers of well-known content types (typically prefixed with "x-content/"), e.g. x-content/image-dcf for camera memory cards. See the shared-mime-info specification for more on x-content types.

This is an asynchronous operation (see mountGuessContentTypeSync for the synchronous version), and is finished by calling mountGuessContentTypeFinish with the mount and AsyncResult data returned in the callback.

Since: 2.18

-> m [Text]	Returns: a `Nothing`-terminated array of content types or `Nothing` on error. Caller should free this array with `strfreev` when done with it. (Can throw `GError`)

Tries to guess the type of content stored on mount. Returns one or more textual identifiers of well-known content types (typically prefixed with "x-content/"), e.g. x-content/image-dcf for camera memory cards. See the shared-mime-info specification for more on x-content types.

This is an synchronous operation and as such may block doing IO; see mountGuessContentType for the asynchronous version.

Since: 2.18

isShadowed

mountIsShadowed Source #

Arguments

:: (HasCallStack, MonadIO m, IsMount a)
=> a	`mount`: A `Mount`.
-> m Bool	Returns: `True` if `mount` is shadowed.

Determines if mount is shadowed. Applications or libraries should avoid displaying mount in the user interface if it is shadowed.

A mount is said to be shadowed if there exists one or more user visible objects (currently Mount objects) with a root that is inside the root of mount.

One application of shadow mounts is when exposing a single file system that is used to address several logical volumes. In this situation, a VolumeMonitor implementation would create two Volume objects (for example, one for the camera functionality of the device and one for a SD card reader on the device) with activation URIs gphoto2://[usb:001,002]/store1/ and gphoto2://[usb:001,002]/store2/. When the underlying mount (with root gphoto2://[usb:001,002]/) is mounted, said VolumeMonitor implementation would create two Mount objects (each with their root matching the corresponding volume activation root) that would shadow the original mount.

The proxy monitor in GVfs 2.26 and later, automatically creates and manage shadow mounts (and shadows the underlying mount) if the activation root on a Volume is set.

Since: 2.20

remount

mountRemount Source #

Arguments

:: (HasCallStack, MonadIO m, IsMount a, IsMountOperation b, IsCancellable c)
=> a	`mount`: a `Mount`.
-> [MountMountFlags]	`flags`: flags affecting the operation
-> Maybe b	`mountOperation`: a `MountOperation` or `Nothing` to avoid user interaction.
-> Maybe c	`cancellable`: optional `Cancellable` object, `Nothing` to ignore.
-> Maybe AsyncReadyCallback	`callback`: a `AsyncReadyCallback`, or `Nothing`.
-> m ()

Remounts a mount. This is an asynchronous operation, and is finished by calling mountRemountFinish with the mount and GAsyncResults data returned in the callback.

Remounting is useful when some setting affecting the operation of the volume has been changed, as these may need a remount to take affect. While this is semantically equivalent with unmounting and then remounting not all backends might need to actually be unmounted.

remountFinish

mountRemountFinish Source #

Arguments

:: (HasCallStack, MonadIO m, IsMount a, IsAsyncResult b)
=> a	`mount`: a `Mount`.
-> b	`result`: a `AsyncResult`.
-> m ()	(Can throw `GError`)

shadow

mountShadow Source #

Arguments

:: (HasCallStack, MonadIO m, IsMount a)
=> a	`mount`: A `Mount`.
-> m ()

Increments the shadow count on mount. Usually used by VolumeMonitor implementations when creating a shadow mount for mount, see mountIsShadowed for more information. The caller will need to emit the changed signal on mount manually.
