Types

type GConn

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

func NewClient

func NewClient(addr, key string) (*GConn, error)

func NewServer

func NewServer(ip, prng string) (*GConn, error)

NewServer takes an ip to listen on and port range "n:m" and returns a GConn object listening to a port in that range or an error if it can't listen.

func (*GConn) Close

func (gc *GConn) Close() error

func (*GConn) LocalPort

func (gc *GConn) LocalPort() int

func (*GConn) Read

func (gc *GConn) Read(extbuf []byte) (int, error)

func (*GConn) RemoteAddr
