gMountIsShadowed: gMountIsShadowed
Description
Determines if mount is shadowed. Applications or libraries should
avoid displaying mount in the user interface if it is shadowed.Usage
gMountIsShadowed(object)
Value
TRUE if mount is shadowed.
Details
A mount is said to be shadowed if there exists one or more user
visible objects (currently GMount objects) with a root that is
inside the root of mount.
One application of shadow mounts is when exposing a single file
system that is used to address several logical volumes. In this
situation, a GVolumeMonitor implementation would create two
GVolume objects (for example, one for the camera functionality of
the device and one for a SD card reader on the device) with
activation URIs gphoto2://[usb:001,002]/store1/
and gphoto2://[usb:001,002]/store2/. When the
underlying mount (with root
gphoto2://[usb:001,002]/) is mounted, said
GVolumeMonitor implementation would create two GMount objects
(each with their root matching the corresponding volume activation
root) that would shadow the original mount.
The proxy monitor in GVfs 2.26 and later, automatically creates and
manage shadow mounts (and shadows the underlying mount) if the
activation root on a GVolume is set.
