[Discuss-gnuradio] Thread-Safe Blocking?

[Michael Dickens]

In implementing gr-audio-osx, I've figured out (after much debugging)  
that 2 threads are conflicting (GR is 1 thread, CoreAudio is the  
other), and thus I need a semaphore or equivalent ... needs to be  
thread-safe.  Does GR have a preference of what to use for this?  Or  
is it OS- and programmer-dependent?  Thanks! - MLD

ps> gr-audio-osx -almost- works, excepting this one issue (as far as  
I have found).  Once that's resolved, I'll do some internal testing  
at UND over the holidays to flush out any other issues.  Look for a  
release sometime in early January.
