Here is my "old and out-dated" experimental library:

http://appcore.home.comcast.net/

IMHO, the there are three very useful API's on here.




(1) The x86 lock-free support assembly library:

(2) The zero-overhead single-producer/consumer lock-free queue

http://appcore.home.comcast.net/appcore/include/ac_queue_spsc_h.html
http://appcore.home.comcast.net/appcore/src/ac_queue_spsc_c.html




(3) The zero-overhead eventcount

I am currently working on incorporating my new VZOOM library into some 
in-house server software; however, I would be happy to discuss AppCore, if 
you need any more information...
