How to do it...

It is considered that spawning separate sub-processes instead of threads makes a program more reliable, because termination of a sub-process does not terminate the main process. We won't argue with that assumption here, and just see how data sharing between processes can be implemented.

1. A lot of headers are required for this recipe:

#include <boost/interprocess/managed_shared_memory.hpp> 
#include <boost/interprocess/containers/deque.hpp> 
#include <boost/interprocess/allocators/allocator.hpp> 
#include <boost/interprocess/sync/interprocess_mutex.hpp> 
#include <boost/interprocess/sync/interprocess_condition.hpp> 
#include <boost/interprocess/sync/scoped_lock.hpp> 
 
#include <boost/optional.hpp> 

2. Now, we need to define our structure, ...
