IRL

What is this?

It is a thread-safe freeware resolver library for Un*x

Is it compatible with the "standard" resolver library?

In some areas, yes. In some other areas, no.
It supports most options in /etc/resolv.conf
It does not support the same API as the normal resolver. It is much simpler.
It is just as paranoid as the normal resolver.
It requires that the nameserver(s) that is queries support "recursion".
By default it is a bit more aggressive doing retransmits.
It always uses UDP.

Why did you make it?

I needed a freeware thread-safe resolver library not covered by *PL license agreements.

Why is it called "irl" ?
