Event notification library
The libevent API executes a callback function when a specific event occurs on a file descriptor or after a timeout has been reached. It also supports callbacks due to signals or regular timeouts. It is meant to replace the asynchronous event loop found in event-driven network servers. 'libevent' currently supports /dev/poll, kqueue(2), select(2), poll(2) and epoll(4). It also has experimental support for real-time signals. The internal event mechanism is independent of the exposed event API, so a simple update of libevent provides new functionality without having to redesign applications. As a result, Libevent allows for portable application development and provides the most scalable event notification mechanism available on an operating system.
