## Detailed Description

The Mount interface represents user-visible mounts.

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. It 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 AsyncReady. To unmount a Mount instance, first call unmount(). The callback slot will be called when the operation has resolved (either with success or failure), and a AsyncReady structure will be passed to the callback. That callback should then call unmount_finish() with the AsyncReady data to see if the operation was completed successfully.

This is an asynchronous operation, and is finished by calling guess_content_type_finish().

Parameters

  slot | A callback which will be called when the operation is completed or canceled.

|  | const Glib::RefPtr< Cancellable > & | cancellable,
|  | bool | force_rescan = true )

Tries to guess the type of content stored on the 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, and is finished by calling guess_content_type_finish().

Parameters

  slot | A callback which will be called when the operation is completed or canceled.
  cancellable | A cancellable object which can be used to cancel the operation.
  force_rescan | Whether to force a rescan of the content. Otherwise a cached result will be used if available.

## ◆ guess_content_type_finish()

std::vector< Glib::ustring > Gio::Mount::guess_content_type_finish | ( | const Glib::RefPtr< AsyncResult > & | result | ) |

Finishes guessing content types of the Mount.

void Gio::Mount::guess_content_type_sync | ( | const Glib::RefPtr< Cancellable > & | cancellable,
|  | bool | force_rescan = true )

## ◆ is_shadowed()

bool Gio::Mount::is_shadowed | ( |  | ) | const

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 glibmm 2.20

Returns
  `true` if mount is shadowed.

## ◆ on_changed()

## ◆ remount() [1/4]

|  | const SlotAsyncReady & | slot,
|  | const Glib::RefPtr< Cancellable > & | cancellable,
|  | MountFlags | flags = MountFlags::NONE )

Remounts a mount.

This is an asynchronous operation, and is finished by calling mount_finish() with the AsyncResult data returned in the callback slot.

Remounting is useful when some setting affecting the operation of the volume has been changed, as this 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.

Parameters

  operation | A mount operation.
  slot | A callback which will be called when the operation is completed or canceled.
  cancellable | A cancellable object which can be used to cancel the operation.
  flags | Flags affecting the operation.

|  | const SlotAsyncReady & | slot,
|  | MountFlags | flags = MountFlags::NONE )

This is an asynchronous operation, and is finished by calling mount_finish() with the AsyncResult data returned in the callback slot.

Remounting is useful when some setting affecting the operation of the volume has been changed, as this 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.
