  43  * GMountIface:
  44  * @g_iface: The parent interface.
  45  * @changed: Changed signal that is emitted when the mount's state has changed.
  46  * @unmounted: The unmounted signal that is emitted when the #GMount have been unmounted. If the recipient is holding references to the object they should release them so the object can be finalized.
  47  * @pre_unmount: The pre_unmout signal that is emitted when the #GMount will soon be emitted. If the recipient is somehow holding the mount open by keeping an open file on it it should close the file.
  48  * @get_root: Gets a #GFile to the root directory of the #GMount.
  49  * @get_name: Gets a string containing the name of the #GMount.
  50  * @get_icon: Gets a #GIcon for the #GMount.
  51  * @get_uuid: Gets the UUID for the #GMount. The reference is typically based on the file system UUID for the mount in question and should be considered an opaque string. Returns %NULL if there is no UUID available.
  52  * @get_volume: Gets a #GVolume the mount is located on. Returns %NULL if the #GMount is not associated with a #GVolume.
  53  * @get_drive: Gets a #GDrive the volume of the mount is located on. Returns %NULL if the #GMount is not associated with a #GDrive or a #GVolume. This is convenience method for getting the #GVolume and using that to get the #GDrive.
  54  * @can_unmount: Checks if a #GMount can be unmounted.
  55  * @can_eject: Checks if a #GMount can be ejected.
  56  * @unmount: Starts unmounting a #GMount.
  57  * @unmount_finish: Finishes an unmounting operation.
  58  * @eject: Starts ejecting a #GMount.
  59  * @eject_finish: Finishes an eject operation.
  60  * @remount: Starts remounting a #GMount.
  61  * @remount_finish: Finishes a remounting operation.
  62  * @guess_content_type: Starts guessing the type of the content of a #GMount.
  63  *     See g_mount_guess_content_type() for more information on content
  64  *     type guessing. This operation was added in 2.18.
  65  * @guess_content_type_finish: Finishes a contenet type guessing operation. Added in 2.18.
  66  * @guess_content_type_sync: Synchronous variant of @guess_content_type. Added in 2.18
  67  * @unmount_with_operation: Starts unmounting a #GMount using a #GMountOperation. Since 2.22.
  68  * @unmount_with_operation_finish: Finishes an unmounting operation using a #GMountOperation. Since 2.22.
  69  * @eject_with_operation: Starts ejecting a #GMount using a #GMountOperation. Since 2.22.
  70  * @eject_with_operation_finish: Finishes an eject operation using a #GMountOperation. Since 2.22.
  71  * @get_default_location: Gets a #GFile indication a start location that can be use as the entry point for this mount. Since 2.24.
  72  * @get_sort_key: Gets a key used for sorting #GMount instance or %NULL if no such key exists. Since 2.32.
  73  *
  74  * Interface for implementing operations for mounts.
