[Openal] Unqueuing all buffers from a stream

[Nolan Darilek]

I'm working on my streaming implementation and am confused about  
something. I'm trying to implement random music on levels, so at some  
point my code needs to unqueue everything associated with a stream  
and queue new music. At the moment I'm getting an invalid operation  
on my alUnqueueBuffers() call.

Based on what I've read in the programmer's manual, I'm guessing that  
this is because I'm iterating through the list of AL_QUEUED_BUFFERS  
and attempting to unqueue all of them, but because some/none of them  
have been processed, the code is failing.

So, is there any way to unqueue all buffers from a stream, even those  
that have not yet been processed? AFAIK the source has been stopped,  
which I'd have thought was all that'd be necessary to yank  
unprocessed buffers from the queue. Or am I missing/misunderstanding  
something?

Thanks in advance.
