Golang Packet.WriteToFile Examples

Example #1

File: outToFile.go Project: sunwxg/golibwireshark

func main() {
	file := "../../1.pcap"
	outfile := "o.pcap"

	err := golibwireshark.Init(file, outfile)
	if err != nil {
		fmt.Printf("open file failed\n")
		return
	}
	defer golibwireshark.Clean()

	//golibwireshark.PrintPacket()

	var p golibwireshark.Packet

	for {
		p.GetPacket()
		if p.Edt == nil {
			break
		}

		p.WriteToFile()

		p.FreePacket()

	}
}

Example #2

File: golibwireshark_test.go Project: sunwxg/golibwireshark

func TestWriteToFile(t *testing.T) {
	file := "1.pcap"
	err := golibwireshark.ReOpenInputFile(file)
	if err != nil {
		t.Fatalf("%s", err)
	}

	err = golibwireshark.ReOpenOutputFile("o.pcap")
	if err != nil {
		t.Fatalf("%s", err)
	}

	var p golibwireshark.Packet

	p.GetPacket()
	if p.Edt == nil {
		fmt.Println("can't find packet")
		os.Exit(1)
	}

	err = p.WriteToFile()
	if err != nil {
		t.Errorf("%s", err)
	}

	p.FreePacket()
	golibwireshark.CloseInputFile()
	golibwireshark.CloseOutputFile()
}
