Moreover how can I tranfers messages between the 2 involved threads
using condition variables? I though that it would need to use an
intermediate queue of fifo? Using the Mac IPC allows directly to do
that...
Do it in the process' memory? You have a pthread mutex, it can
protect a private queue in addition to the condition variable.
Do you mean using "pthread_mutex" and "pthread_cond_signal/wait" API?
How can this be done?
In fact, the condition variable is only interesting when the queue
runs dry. This is always more efficient than trying to queue the
memory in the kernel. Besides, you are limited to a queue depth of 16
(default 5) when you use Mach message queues. Not really much of a
queue to store things in, when you think about it.
OK... Thanks
Stephane
