Libevent is an asynchronous event notification library that provides a
mechanism to execute a callback function when a specific event occurs
on a file descriptor or after a timeout has been reached.
It is meant to replace the asynchronous event loop found in
event driven network servers. Currently, libevent supports /dev/poll,
kqueue(2), event ports, select(2), poll(2) and epoll(4).
The libevent_core library includes event loops, timers, buffer code,
and various small compatibility functions.
If you're writing software that only uses libevent's event loop, you
should link against only the libevent_core library.
