ogg dev - Feb 2008 - How do I seek to the beginning of an ogg stream?

Hello,

I've been trying to figure out (without much success) how to perform  
a seek to the beginning of an ogg stream? I've tried examining the  
libvorbis source code but because it's concerned with seeking to an  
arbitrary point in the stream, it's a little more complex than I'd  
like it to be. Really, what I'm trying to figure out is how to reset  
all of the ogg data structures so that I can replay an audio file  
from it's beginning. Does anyone have any pointers or can offer some  
insight into this task?
