libevent-2.1-6 - 2.1.8-stable-4 main

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).
.
For backward compatibility and to transition to "libevent_core only"
or "libevent_core + libevent_extra", the libevent source package builds
the libevent library that includes everything in libevent_core and
libevent_extra.
