36 * @short_description: Authentication methods for mountable locations
39 * #GMountOperation provides a mechanism for authenticating mountable
40 * operations, such as loop mounting files, hard drive partitions or
43 * Mounting operations are handed a #GMountOperation that then can use
44 * if they require any privileges or authentication for their volumes
45 * to be mounted (e.g. a hard disk partition or an encrypted filesystem),
46 * or if they are implementing a remote server protocol which requires
47 * user credentials such as FTP or WebDAV.
49 * Users should instantiate a subclass of this that implements all
50 * the various callbacks to show the required dialogs, such as
