62 * @is_media_check_automatic: Returns %TRUE if the #GDrive is capable of automatically detecting media changes.
63 * @can_poll_for_media: Returns %TRUE if the #GDrive is capable of manually polling for media change.
64 * @can_eject: Returns %TRUE if the #GDrive can eject media.
65 * @eject: Ejects a #GDrive.
66 * @eject_finish: Finishes an eject operation.
67 * @poll_for_media: Poll for media insertion/removal on a #GDrive.
68 * @poll_for_media_finish: Finishes a media poll operation.
69 * @get_identifier: Returns the identifier of the given kind, or %NULL if
70 * the #GDrive doesn't have one.
71 * @enumerate_identifiers: Returns an array strings listing the kinds
72 * of identifiers which the #GDrive has.
