You may try the *shared_memory_object* class defined in *
boost\interprocess\shared_memory_object.hpp*. The *truncate *function is to
allocate desired size of memory. Also, the *mapped_region *class defined in
*boost\interprocess\mapped_region.hpp* should be used to get the address of
shared memory and map to client program. Refer to this page for more
details:

.

Best regards!
