Weballocator: A general purpose allocator for managed memory segments As seen, Boost.Interprocess offers raw memory allocation and object construction using managed memory segments (managed shared memory, managed mapped files...) and one of the first user requests is the use of containers in managed shared memories. WebBoost.Interprocess offers 4 managed memory segment classes: To manage a shared memory mapped region ( basic_managed_shared_memory class). To manage a memory mapped file ( basic_managed_mapped_file ). To manage a heap allocated ( operator new) memory buffer ( basic_managed_heap_memory class).
