Introduction

In this tutorial we learn how to install ivykis on CentOS 8.

What is `ivykis`

ivykis is a library for asynchronous I/O readiness notification. It is a thin, portable wrapper around OS-provided mechanisms such as epoll_create(2), kqueue(2), poll(2), poll(7d) (/dev/poll) and port_create(3C). ivykis was mainly designed for building high-performance network applications, but can be used in any event-driven application that uses poll(2)able file descriptors as its event sources.
