 * GDriveIface:
 * @g_iface: The parent interface.

 * @disconnected: The removed signal that 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.
 * @eject_button: Signal emitted when the physical eject button (if any) of a drive have been pressed.
 * @get_name: Returns the name for the given #GDrive.
 * @get_icon: Returns a #GIcon for the given #GDrive.
 * @has_volumes: Returns %TRUE if the #GDrive has mountable volumes.
 * @get_volumes: Returns a list #GList of #GVolume for the #GDrive.
 * @is_media_removable: Returns %TRUE if the #GDrive supports removal and insertion of media.
 * @has_media: Returns %TRUE if the #GDrive has media inserted.
 * @is_media_check_automatic: Returns %TRUE if the #GDrive is capabable of automatically detecting media changes.
 * @can_poll_for_media: Returns %TRUE if the #GDrive is capable of manually polling for media change.
 * @can_eject: Returns %TRUE if the #GDrive can eject media.
 * @eject: Ejects a #GDrive.
 * @eject_finish: Finishes an eject operation.
 * @poll_for_media: Poll for media insertion/removal on a #GDrive.
 * @poll_for_media_finish: Finishes a media poll operation.
 * @get_identifier: Returns the identifier of the given kind, or %NULL if 
 *    the #GDrive doesn't have one.
 * @enumerate_identifiers: Returns an array strings listing the kinds
 *    of identifiers which the #GDrive has.
 *
 * 
 * Interface for creating #GDrive implementations.
