gobject:binding-dup-source (binding)

binding -- a g:binding object

The g:object source instance, or nil if the source does not exist any more.

Retrieves the g:object instance used as the source of the binding. A g:binding object can outlive the g:object source instance as the binding does not hold a strong reference to the source. If the source is destroyed before the binding then this function will return nil.
