What problem does it solve?

EPICS module developers need reliable, OS-independent building blocks for concurrency, timing, inter-thread communication, and lifecycle integration.

Core Features & Use Cases

• Threading with epicsThread: Create runnable threads, manage priorities and stack sizes, and use one-time initialization and thread-local storage.
• Synchronization & messaging: Use epicsMutex, epicsEvent, and epicsMessageQueue for safe coordination between threads.
• Performance-oriented data structures: Apply epicsRingPointer and epicsRingBytes for lock-free or bounded buffering patterns.
• Timers, time, and observability: Schedule periodic work with epicsTimer, handle timestamps with epicsTime, and log issues via errlog.
• IOC integration primitives: Register IOC shell commands, init hooks, exit handlers, and subroutine/aSub functions to wire logic into IOC lifecycles.
• Networking portability (osiSock): Abstract socket creation and address conversion for cross-platform support.

Quick Start

Ask the AI to generate a minimal, production-style EPICS module snippet that uses an epicsThread worker plus an epicsEvent-driven shutdown, logs startup/shutdown with errlog, and registers an iocsh command for toggling the worker behavior.
