[openvrml-develop] determining AudioClip node child of Sound node

[-oli- <ol...@fr...>]

Hi!

How can I find out from within the class NodeAudioClip if the AudioClip 
node is [currently] child (i.e. source) of a Sound node?
I need this to determine if the audio data has to be played or not, because 
this check is done in the method NodeAudioClip::update().

Thanks for help!
