# Libunbound wrapper in Go


I've created a small wrapper for [libunbound](https://unbound.net) for use in
[Go](http://www.golang.org).

The code can be [found at github](http://github.com/miekg/unbound). It depends
on my Go DNS library which can be [found here](http://github.com/miekg/dns).

[Official announcement on the Unbound-users@
list](https://unbound.nlnetlabs.nl/pipermail/unbound-users/2012-July/002431.html).

To give
you a little taste of how it looks, I've (re)created tutorials 2 to 6 in Go.
Tutorial 2 looks like this, for instance:

    package main

    // https://www.unbound.net/documentation/libunbound-tutorial-2.html

    import (
            "dns"
            "fmt"
            "os"
            "unbound"
    )

    func main() {
            u := unbound.New()
            defer u.Destroy()

            if err := u.ResolvConf("/etc/resolv.conf"); err != nil {
                    fmt.Printf("error %s\n", err.Error())
                    os.Exit(1)
            }

            if err := u.Hosts("/etc/hosts"); err != nil {
                    fmt.Printf("error %s\n", err.Error())
                    os.Exit(1)
            }

            r, err := u.Resolve("www.nlnetlabs.nl.", dns.TypeA, dns.ClassINET)
            if err != nil {
                    fmt.Printf("error %s\n", err.Error())
                    os.Exit(1)
            }
            fmt.Printf("%+v\n", r)
    }
