34  * @short_description: Object used for authentication and user interaction
35  * @include: gio/gio.h
36  *
37  * #GMountOperation provides a mechanism for interacting with the user.
38  * It can be used for authenticating mountable operations, such as loop
39  * mounting files, hard drive partitions or server locations. It can
40  * also be used to ask the user questions or show a list of applications
41  * preventing unmount or eject operations from completing.
42  *
43  * Note that #GMountOperation is used for more than just #GMount
44  * objects – for example it is also used in g_drive_start() and
45  * g_drive_stop().
46  *
47  * Users should instantiate a subclass of this that implements all the
48  * various callbacks to show the required dialogs, such as
49  * #GtkMountOperation. If no user interaction is desired (for example
50  * when automounting filesystems at login time), usually %NULL can be
51  * passed, see each method taking a #GMountOperation for details.
