<para>
This extension provides inteface to
<link

library - a high performance full-featured event loop written in C.
</para>
¬e.no-windows.extension;
<para>
<emphasis>Libev</emphasis>
is an event loop: one registers interest in certain events (such as a file
descriptor being readable or a timeout occurring), and it will manage these
event sources and provide the program with events.
</para>
<para>
To do this, it must take more or less complete control over the process (or
thread) by executing the event loop handler, and will then communicate
events via a callback mechanism.
</para>
<para>
You register interest in certain events by registering so-called event
watchers, and then hand it over to libev by starting the watcher.
