Boost.Interprocess

Wraps OS-specific APIs like UNIX sem_open and Windows CreateSemaphore into a high-level C++ interface, ensuring cross-platform compatibility without code changes, as highlighted in the philosophy.

As a header-only library, it requires no separate compilation or linking, simplifying integration and build processes, which is explicitly stated in the properties section.

Includes semaphores, mutexes, condition variables, and upgradable mutexes that can be placed in shared memory or memory-mapped files, enabling robust interprocess coordination as listed in the features.

Provides utilities to construct C++ objects, including STL-like containers, directly in shared memory, facilitating complex data sharing between processes, a key feature mentioned in the README.
