Tiny epoll-based event loop library for event-driven Linux applications.

• I/O listeners for handling events on sockets and friends
• Timers with millisecond resolution
• Dispatch and exit handling that is thread- and signal-safe and lock-free
• Delightfully simple and clean interface
• Integration with systemd sd-event loop

• Add file and directory listener support built on inotify
• Add built-in signal handling support (if signalfd can be be setup in a bullet-proof way)
• Enhance event_dispatch() to allow high throughput capability (currently limited by socket buffer size).
