Source.getId

Returns the numeric ID for a particular source. The ID of a source is a positive integer which is unique within a particular main loop context. The reverse mapping from ID to source is done by [glib.main_context.MainContext.findSourceById].

You can only call this function while the source is associated to a #GMainContext instance; calling this function before [glib.source.Source.attach] or after [glib.source.Source.destroy] yields undefined behavior. The ID returned is unique within the #GMainContext instance passed to [glib.source.Source.attach].
