Functions

func InterfaceForSource

func InterfaceForSource(ip net.IP) (*net.Interface, error)

InterfaceForSource returns a multicast-capable interface that can communicate with given IP.

Types

type Conn

type Conn interface {
	net.PacketConn
	SetReadBuffer(int) error
}

Conn is a Multicast connection.

func NewMultiConn

func NewMultiConn(
	address string,
	listenPacket func(network, address string) (net.PacketConn, error),
) (Conn, error)

NewMultiConn allocates a MultiConn.

func NewSingleConn

func NewSingleConn(
	intf *net.Interface,
	address string,
	listenPacket func(network, address string) (net.PacketConn, error),
) (Conn, error)

NewSingleConn allocates a SingleConn.

type MultiConn

type MultiConn struct {
	// contains filtered or unexported fields
}

MultiConn is a multicast connection that works in parallel on all interfaces.
