It lets you create and manage semaphores, shared memory segments, and message queues for coordinating work across multiple processes on Unix-like systems. The module has no runtime dependencies and exposes these low-level IPC mechanisms directly to Python, making it suitable for applications that need efficient, kernel-level process synchronization without higher-level abstractions.\n\nThe package is production-stable (Development Status 5), actively maintained, and has been in use since its first release with no reported bugs in the core code for seven years. Pre-built wheels are available for common platforms, though building from source requires a C compiler. The permissive BSD-3-Clause license makes it suitable for both open-source and commercial projects.","worth_installing":"Yes, if you need low-level POSIX IPC primitives for multi-process coordination on Unix-like systems. The package is stable, actively maintained, has no known vulnerabilities, and carries a permissive license. Install friction is moderate due to C compilation, but pre-built wheels cover common platforms. Not suitable if you need Windows support without Cygwin or if you prefer higher-level abstractions like multiprocessing or queue modules."},"id":"posix-ipc","links":{"html":"https://skillfed.io/packages/posix-ipc","md":"https://skillfed.io/packages/posix-ipc.md","pypi":"https://pypi.org/project/posix-ipc/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2025-10-23","license_spdx":null,"license_treatment":"permissive","name":"posix-ipc","python_support":"unspecified","summary":"POSIX IPC primitives (semaphores, shared memory and message queues) for Python"},"popularity":{"monthly_downloads":448256,"position":6603,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"1.3.2"}
