Package goshark use tshark to decode IP packet and create data struct to analyse packet.

### Dependency

* tshark

### Examples

```go

file := "2.pcap"

d := goshark.NewDecoder()

if err := d.DecodeStart(file); err != nil {

    log.Println("Decode start fail:", err)

    return

}

defer d.DecodeEnd()

f, err := d.NextPacket()

if err != nil {

    log.Println("Get packet fail:", err)

    return

}

key := "igmp.maddr"

value, ok := f.Iskey(key)

if ok {

    fmt.Printf("key: %s\nvalue: %s\n", key, value)

}

```

Output:

```

key: igmp.maddr

value: 224.0.0.251

```
