"The libevent API provides a mechanism to execute a callback
function when a specific event occurs on a file descriptor or after a
timeout has been reached. Furthermore, libevent also support callbacks
due to signals or regular timeouts.

network servers. An application just needs to call event_dispatch() and
then add or remove events dynamically without having to change the event
