[Clam-devel] main.cxx for Constructing_and_playing_a_simple_network: GetAudioFile()

[David García Garzón]

Yes, sorry, we forgot to update the example after changes in last releases. 
Now the example is up to date and compiling again.

The AudioFile object, that contains the file header, became a hidden 
implementation class. We added a GetHeader method on the processings to 
access such information which leads to a simpler interface. Also a cast to 
the concrete processing class was also needed to be able to use such a 
method.

Thanks for noticing it out.

David.
