|
|
* @short_description: mounted volume management
|
|
*
|
|
* Class for managing mounted volumes.
|
|
*
|
|
* Unmounting volumes is an asynchronous operation. For more information about
|
|
* asynchronous operations, see #GAsyncReady and #GSimpleAsyncReady. To unmount a volume,
|
|
* first call g_volume_unmount() with (at least) the volume and a #GAsyncReadyCallback.
|
|
* The callback will be fired when the operation has resolved (either with success or failure),
|
|
* and a #GAsyncReady structure will be passed to the callback.
|
|
* That callback should then call g_volume_unmount_finish() with
|
|
* the volume and the #GAsyncReady data to see if the operation was completed successfully.
|
|
* If an @error is present when g_volume_unmount_finish() is called, then it will
|
|
* be filled with any error information.
|
|
*
|
|
* Ejecting volumes is also an asynchronous operation.
|
|
* To eject a volume, call g_volume_eject() with (at least) the volume to eject
|
|
* and a #GAsyncReadyCallback. The callback will be fired when the eject operation
|
|
* has resolved (either with success or failure), and a #GAsyncReady structure will
|
|
* be passed to the callback. That callback should then call g_volume_eject_finish()
|
|
* with the volume and the #GAsyncReady data to determine if the operation was completed
|
|
* successfully. If an @error is present when g_volume_eject_finish() is called, then
|
|
* it will be filled with any error information.
