Introduction

In this tutorial we learn how to install libasr on Fedora 34.

What is `libasr`

Libasr allows to run DNS queries and perform hostname resolutions in a fully asynchronous fashion. The implementation is thread-less, fork-less, and does not make use of signals or other “tricks” that might get in the developer’s way. The API was initially developed for the OpenBSD operating system, where it is natively supported. This library is intended to bring this interface to other systems. It is originally provided as a support library for the portable version of the OpenSMTPD daemon, but it can be used in any other contexts. libasr 1.0.4 5.fc34 x86_64 39 k libasr-1.0.4-5.fc34.src.rpm fedora Free, simple and portable asynchronous resolver library https BSD Libasr allows to run DNS queries and perform hostname resolutions in a fully asynchronous fashion.
