Types

}

type Writer

type Writer struct {
	Buffer bytes.Buffer
	// contains filtered or unexported fields
}

Writer wraps an underlying o.Writer to write packet data in PCAP format. See http://wiki.wireshark.org/Development/LibpcapFileFormat for information on the file format.

For those that care, we currently write v2.4 files with nanosecond or microsecond timestamp resolution and little-endian encoding.

func NewWriter

func NewWriter(buf bytes.Buffer) *Writer

func NewWriterNanos

func NewWriterNanos(buf bytes.Buffer) *Writer

func (*Writer) WriteDataPcapBuffer

func (w *Writer) WriteDataPcapBuffer(h *gabs.Container) error

WriteDataToBuffer writes a file header out to the writer. This must be called exactly once per output.

func (*Writer) WriteDataToBuffer

func (w *Writer) WriteDataToBuffer(h *gabs.Container) error

WriteDataToBuffer writes a file header out to the writer. This must be called exactly once per output.

func (*Writer) WritePcapHeader

func (w *Writer) WritePcapHeader(snaplen uint32, linkType uint32) error

WriteFileHeader writes a file header out to the writer. This must be called exactly once per output.

func (*Writer) WritePcapPacket

func (w *Writer) WritePcapPacket(ci gopacket.CaptureInfo, data []byte) error

WritePacket writes the given packet data out to the file.
