unref

Decrements the reference count of dir.

Once the reference count reaches zero, the directory will be closed and all resources associated with it will be freed. If method@GLib.Dir.close is called when the reference count is greater than zero, the directory is closed but the GDir structure will not be freed until its reference count reaches zero.

It is an error to call any of the GDir methods other than method@GLib.Dir.ref and method@GLib.Dir.unref on a GDir after calling method@GLib.Dir.close on it.
