# GO_REUSEPORT
[![Build Status](https://travis-ci.org/kavu/go_reuseport.png?branch=master)](https://travis-ci.org/kavu/go_reuseport)
[![codecov](https://codecov.io/gh/kavu/go_reuseport/branch/master/graph/badge.svg)](https://codecov.io/gh/kavu/go_reuseport)
[![GoDoc](https://godoc.org/github.com/kavu/go_reuseport?status.png)](https://godoc.org/github.com/kavu/go_reuseport)
**GO_REUSEPORT** is a little expirement to create a `net.Listener` that supports [SO_REUSEPORT](http://lwn.net/Articles/542629/) socket option.
For now, Darwin and Linux (from 3.9) systems are supported. I'll be pleased if you'll test other systems and tell me the results.
documentation on [godoc.org](http://godoc.org/github.com/kavu/go_reuseport "go_reuseport documentation").
## Example ##
```go
package main
import (
"fmt"
"html"
"net/http"
"os"
"runtime"
"github.com/kavu/go_reuseport"
)
func main() {
listener, err := reuseport.Listen("tcp", "localhost:8881")
if err != nil {
panic(err)
}
defer listener.Close()
server := &http.Server{}
http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
fmt.Println(os.Getgid())
fmt.Fprintf(w, "Hello, %q\n", html.EscapeString(r.URL.Path))
})
panic(server.Serve(listener))
}
```
Now you can run several instances of this tiny server without `Address already in use` errors.
## Thanks
Inspired by [Artur Siekielski](https://github.com/aartur) [post](http://freeprogrammersblog.vhex.net/post/linux-39-introdued-new-way-of-writing-socket-servers/2) about `SO_REUSEPORT`.
