Libevent

libevent: High Performance Network Server Event Library

Develop fast and scalable network servers with libevent, providing APIs for event scheduling and callback notifications for I/O events and time delays.

What is Libevent?

libevent is an open source event notification library that provides a mechanism to execute callbacks when events occur. It is optimized for high-performance networking servers that process many concurrent connections and I/O events.

Some key features of libevent include:

• Support for sockets, timeouts, signals, and periodic events
• An event-driven model that allows handling multiple events with minimal resource usage
• APIs for scheduling events and executing callbacks when the events occur
• Portability across various platforms like Windows, Linux, BSD variants, and more
• Integration with various networking libraries/APIs like select, poll, epoll, kqueue, event ports

libevent is used by several well-known software projects including Memcached, Mozilla NSS, and OpenVPN. It helps build fast, efficient event-driven network applications that can process thousands of concurrent connections and scale well. The event-driven model and optimization for I/O operations makes it well-suited for servers and networking tools.
