`k` : |

### GNOME_VFS_TYPE_VOLUME_MONITOR

### GNOME_VFS_VOLUME_MONITOR()

    #define GNOME_VFS_VOLUME_MONITOR(o)          (G_TYPE_CHECK_INSTANCE_CAST ((o), GNOME_VFS_TYPE_VOLUME_MONITOR, GnomeVFSVolumeMonitor))

### GNOME_VFS_VOLUME_MONITOR_CLASS()

### GnomeVFSVolumeMonitor

    typedef struct _GnomeVFSVolumeMonitor GnomeVFSVolumeMonitor;

### GnomeVFSVolumeMonitorClass

    typedef struct {
    	GObjectClass parent_class;

    	void (* volume_mounted)	  	(GnomeVFSVolumeMonitor *volume_monitor,
    				   	 GnomeVFSVolume	       *volume);
    	void (* volume_pre_unmount)	(GnomeVFSVolumeMonitor *volume_monitor,
    				   	 GnomeVFSVolume	       *volume);
    	void (* volume_unmounted)	(GnomeVFSVolumeMonitor *volume_monitor,

    } GnomeVFSVolumeMonitorClass;

### gnome_vfs_get_volume_monitor ()

    GnomeVFSVolumeMonitor* gnome_vfs_get_volume_monitor
                                                (void);

Returns a pointer to the GnomeVFSVolumeMonitor singleton. GnomeVFSVolumeMonitor is a singleton, this means it is guaranteed to exist and be valid until `gnome_vfs_shutdown()` is called. Consequently, it doesn't need to be refcounted since gnome-vfs will hold a reference to it until it is shut down.

Returns : | a pointer to the GnomeVFSVolumeMonitor singleton.

Since 2.6

### gnome_vfs_volume_monitor_emit_pre_unmount ()

    void        gnome_vfs_volume_monitor_emit_pre_unmount
                                                (GnomeVFSVolumeMonitor *volume_monitor,
                                                 GnomeVFSVolume *volume);

Emits the "pre-unmount" signal on `volume`.

`volume_monitor` : | the GnomeVFSVolumeMonitor
`volume` : | a GnomeVFSVolume

Since 2.6

### gnome_vfs_volume_monitor_get_connected_drives ()

    GList*      gnome_vfs_volume_monitor_get_connected_drives
                                                (GnomeVFSVolumeMonitor *volume_monitor);

`volume_monitor` : |
Returns : |

Since 2.6

### gnome_vfs_volume_monitor_get_drive_by_id ()

    GnomeVFSDrive* gnome_vfs_volume_monitor_get_drive_by_id
                                                (GnomeVFSVolumeMonitor *volume_monitor,
                                                 gulong id);

Looks for a GnomeVFSDrive whose id is `id`. A valid `volume_monitor` to pass to this function can be acquired using `gnome_vfs_get_volume_monitor()`

`volume_monitor` : | a GnomeVFSVolumeMonitor
`id` : | the GnomeVFSVolume id to look for
Returns : | the GnomeVFSDrive corresponding to `id`, or NULL if no GnomeVFSDrive with a matching id could be found. The caller owns a reference on the returned drive, and must call `gnome_vfs_drive_unref` when it no longer needs it.

Since 2.6

### gnome_vfs_volume_monitor_get_mounted_volumes ()

    GList*      gnome_vfs_volume_monitor_get_mounted_volumes
                                                (GnomeVFSVolumeMonitor *volume_monitor);

Gets the list of all the mounted GnomeVFSVolume volumes.

`volume_monitor` : | the GnomeVFSVolumeMonitor
Returns : | GList of GnomeVFSVolume. The GnomeVFSVolume objects must be unreffed by the caller when no longer needed with `gnome_vfs_volume_unref()` and the GList must be freed.

Since 2.6

### gnome_vfs_volume_monitor_get_type ()

    GType       gnome_vfs_volume_monitor_get_type
                                                (void);

Returns : |

### gnome_vfs_volume_monitor_get_volume_by_id ()

    GnomeVFSVolume* gnome_vfs_volume_monitor_get_volume_by_id
                                                (GnomeVFSVolumeMonitor *volume_monitor,
                                                 gulong id);

Looks for a GnomeVFSVolume whose id is `id`. A valid `volume_monitor` to pass to this function can be acquired using `gnome_vfs_get_volume_monitor()`

`volume_monitor` : | a GnomeVFSVolumeMonitor
`id` : | the GnomeVFSVolume id to look for
Returns : | the GnomeVFSVolume corresponding to `id`, or NULL if no GnomeVFSVolume with a matching id could be found. The caller owns a reference on the returned volume, and must call `gnome_vfs_volume_unref` when it no longer needs it.

Since 2.6

### gnome_vfs_volume_monitor_get_volume_for_path ()

    GnomeVFSVolume* gnome_vfs_volume_monitor_get_volume_for_path
                                                (GnomeVFSVolumeMonitor *volume_monitor,
                                                 const char *path);

`volume_monitor` : |
`path` : |
Returns : |

Since 2.6

### gnome_vfs_volume_monitor_ref ()

    GnomeVFSVolumeMonitor* gnome_vfs_volume_monitor_ref
                                                (GnomeVFSVolumeMonitor *volume_monitor);

Increases the reference count of a GnomeVFSVolumeMonitor by one.

You shouldn't use this function unless you know what you are doing: GnomeVFSVolumeMonitor is to be used as a singleton object, see `gnome_vfs_get_volume_monitor()` for more details.

`volume_monitor` : | a GnomeVFSVolumeMonitor
Returns : | `volume_monitor` with its refcount increased by one.

Since 2.6

### gnome_vfs_volume_monitor_unref ()

    void        gnome_vfs_volume_monitor_unref  (GnomeVFSVolumeMonitor *volume_monitor);

Decreases the reference count of a GnomeVFSVolumeMonitor by one.

You shouldn't use this function unless you know what you are doing: GnomeVFSVolumeMonitor is to be used as a singleton object, see `gnome_vfs_get_volume_monitor()` for more details.

`volume_monitor` : | a GnomeVFSVolumeMonitor

Since 2.6
