flags affecting the operation
optional gio.Cancellable object, NULL to ignore
a GAsyncReadyCallback to call when the request is satisfied, or NULL
the data to pass to callback function
Deprecated: Use g_file_unmount_mountable_with_operation() instead.
Unmounts a file of type G_FILE_TYPE_MOUNTABLE.
If cancellable is not NULL, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error G_IO_ERROR_CANCELLED will be returned.
When the operation is finished, callback will be called. You can then call g_file_unmount_mountable_finish() to get the result of the operation.
