[Boost-users] Boost.Threads, Boost.Interprocess, mutex

Hello,

In a single process but multithreaded software, should I use 
Boost.Threads synchronization mechanisms or can I use Boost.Interprocess 
synchronization mechanisms without counterparts and without seeing any 
difference ? ( in particular boost::interprocess::interprocess_semaphore 
class )

When using interprocess_mutex, my programm threw a lock_exception. I 
changed to boost::mutex and didn't managed to reproduce it. So, could 
this be related or the lock_exception has same chances to happen with 
boost::mutex ?

I'm using semaphore to synchronize threads, so is it reliable in a 
single process multithreaded software ?

By the way, I'm currently using boost::mutex instances which I lock() 
and unlock() directly. What benefits could I have by using 
boost::unique_lock (with a deferred lock) rather than access directly to 
the mutex instance ?

Thanks in advance.
Axel
