libevent-extra-2.1-7t64 - 2.1.13-stable-1~deb13u1 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).
.
The libevent_extra library includes code for HTTP, DNS, RPC, and so
on.
.
If you're writing software that uses libevent's protocol support, you
need to link libevent_core and libevent_extra as well.
