Here is a very simple example that sends & receives 3 packets:
```go
pinger, err := ping.NewPinger("www.google.com")
if err != nil {
panic(err)
}
pinger.Count = 3
pinger.Run() // blocks until finished
stats := pinger.Statistics() // get send/receive/rtt stats
pinger, err := ping.NewPinger("www.google.com")
if err != nil {
panic(err)
}
pinger.Count = 3
pinger.Run() // blocks until finished
stats := pinger.Statistics() // get send/receive/rtt stats
```
Here is an example that emulates the unix ping command:
```go
pinger, err := ping.NewPinger("www.google.com")
if err != nil {
fmt.Printf("ERROR: %s\n", err.Error())
return
}
pinger.OnRecv = func(pkt *ping.Packet) {
fmt.Printf("%d bytes from %s: icmp_seq=%d time=%v\n",
pkt.Nbytes, pkt.IPAddr, pkt.Seq, pkt.Rtt)
}
pinger.OnFinish = func(stats *ping.Statistics) {
fmt.Printf("\n--- %s ping statistics ---\n", stats.Addr)
fmt.Printf("%d packets transmitted, %d packets received, %v%% packet loss\n",
stats.PacketsSent, stats.PacketsRecv, stats.PacketLoss)
fmt.Printf("round-trip min/avg/max/stddev = %v/%v/%v/%v\n",
stats.MinRtt, stats.AvgRtt, stats.MaxRtt, stats.StdDevRtt)
}
fmt.Printf("PING %s (%s):\n", pinger.Addr(), pinger.IPAddr())
pinger.Run()
pinger, err := ping.NewPinger("www.google.com")
