Libev

libev: High-Performance Event Loop Library

libev is a high-performance event loop/event model library written in C, supporting timers, signals, sockets, pipes and more for efficient asynchronous event handling.

What is Libev?

libev is a high-performance event loop/event model library written in C. It provides an efficient, priority-based callback scheduling mechanism that allows applications to register interest in certain events and respond to them asynchronously when they occur.

Some key capabilities and features of libev include:

• High-performance event loop based on efficient state machines and linked lists for time-ordered event processing
• Supports various event notification interfaces like timers, signals, sockets, pipes, and more
• Lightweight - designed to have a small footprint and minimal external dependencies
• Portable - works across POSIX platforms like Linux, macOS, *BSD
• Integrates easily into applications and other event loops/libraries
• Priority-based callback execution for accurate timing of events
• Support for one-shot, periodic, and repeating events/timers
• Integrated fork handling for safe post-fork event handling

libev is very useful for developing highly concurrent network services, real-time apps, client/server software, audio/video frameworks, emulators, and other event-driven use cases where scalability and accurate event timing are critical.
