I am trying to play with sound datatypes using the extended mode to handle some streaming.

So, I created a DT object setting the SDTA_Mode to mode SDTA_Mode_Extended, but I don't know how to use SDTM_FETCH properly.
Is there some example around?

I know Reggae is better at this, and I already know how to do audio streaming using it. But there, I'd like to do something similar through datatypes for some reasons. :)
