  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.
