- * #GMountOperation provides a mechanism for authenticating mountable
- * operations, such as loop mounting files, hard drive partitions or
- * server locations.
+ * #GMountOperation provides a mechanism for interacting with the user.
+ * It can be used for authenticating mountable operations, such as loop
+ * mounting files, hard drive partitions or server locations. It can
+ * also be used to ask the user questions or show a list of applications
+ * preventing unmount or eject operations from completing.
*
- * Mounting operations are handed a #GMountOperation that then can use
- * if they require any privileges or authentication for their volumes
- * to be mounted (e.g. a hard disk partition or an encrypted filesystem),
- * or if they are implementing a remote server protocol which requires
- * user credentials such as FTP or WebDAV.
+ * Note that #GMountOperation is used for more than just #GMount
+ * objects – for example it is also used in g_drive_start() and
+ * g_drive_stop().
*
- * Users should instantiate a subclass of this that implements all
- * the various callbacks to show the required dialogs, such as
- * #GtkMountOperation.

+ * when automounting filesystems at login time), usually %NULL can be
+ * passed, see each method taking a #GMountOperation for details.
