About C++ and real-time OSs...

Hello,


I have been working on a queue with a condition variable, but
i have noticed that a condition variable does not work
correctly, because the threads must be waiting to be able
to be signaled, if they are not waiting the signal will be lost,
so the way that many are using a condition variable with
a FIFO queue is not correct, they are for example using
this logic on the consumer side:

  while(the_queue.empty())
         {
             the_condition_variable.wait(lock);
         }


and this is not correct, because if the_queue_empty() is true ,
and the last producer thread signals before the consumer
thread is waiting for the condition variable , so this will deadlock,
so i have avoided condition variables and i have designed and 
implemented an efficient real-time and thread-safe and bounded FIFO 
Queue and Stack an i am actually finishing them and they are working 
well, and i will soon posted them on internet.



Thank you,
Amine Moulay Ramdane.
