get_node_path

Returns the `/dev/input/event*` path of this device.

For `GdkDevice`s that possibly coalesce multiple hardware devices (eg. mouse, keyboard, touch,...), this function will return null.

This is most notably implemented for devices of type gdk_source_pen, gdk_source_tablet_pad.

Parameters:

this	a `GdkDevice`

Returns:

the `/dev/input/event*` path of this device
