Queue blocking for producer / consumer threads for win32 / C

Question

I am trying to replace some thread binding with a user queue, the producer is currently using PostThreadMessage, the consumer is using WaitForSingleObject / PeekMessage.

http://www.justsoftwaresolutions.co.uk/threading/implementing-a-thread-safe-queue-using-condition-variables.html will be what I need, but boost, and C ++ is not an option.

Not wanting to redefine the wheel, does anyone have such a queue implemented in C?

in consumer...
   while(true)
      WaitForSingleObject(event)
      acquire_lock
