Boost.Interprocess simplifies the use of common interprocess communication and synchronization mechanisms and offers a wide range of them:

• Shared memory.
• Memory-mapped files.
• Semaphores, mutexes, condition variables and upgradable mutex types to place them in shared memory and memory mapped files.
• Named versions of those synchronization objects, similar to UNIX/Windows sem_open/CreateSemaphore API.
• File locking.
• Relative pointers.
• Message queues.

Also offers higher-level interprocess mechanisms to dynamically allocate portions of a shared memory or a memory mapped file. Using these mechanisms, it offers useful tools to construct C++ objects, including STL-like containers, in shared memory and memory mapped files.
