Types

type TCPConn

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

TCPConn defines a TCP-packet oriented connection

func Dial

func Dial(network, address string) (*TCPConn, error)

Dial connects to the remote TCP port, and returns a single packet-oriented connection

func Listen

func Listen(network, address string) (*TCPConn, error)

Listen acts like net.ListenTCP, and returns a single packet-oriented connection

func (*TCPConn) Close

func (conn *TCPConn) Close() error

Close closes the connection.

func (*TCPConn) LocalAddr

func (conn *TCPConn) LocalAddr() net.Addr

LocalAddr returns the local network address.

func (*TCPConn) ReadFrom

func (conn *TCPConn) ReadFrom(p []byte) (n int, addr net.Addr, err error)

ReadFrom implements the PacketConn ReadFrom method.

func (*TCPConn) SetDSCP

func (conn *TCPConn) SetDSCP(dscp int) error

SetDSCP sets the 6bit DSCP field in IPv4 header, or 8bit Traffic Class in IPv6 header.

func (*TCPConn) SetDeadline

func (conn *TCPConn) SetDeadline(t time.Time) error

SetDeadline implements the Conn SetDeadline method.

func (*TCPConn) SetReadBuffer

func (conn *TCPConn) SetReadBuffer(bytes int) error

SetReadBuffer sets the size of the operating system's receive buffer associated with the connection.

func (*TCPConn) SetReadDeadline

func (conn *TCPConn) SetReadDeadline(t time.Time) error

SetReadDeadline implements the Conn SetReadDeadline method.

func (*TCPConn) SetWriteBuffer

func (conn *TCPConn) SetWriteBuffer(bytes int) error

SetWriteBuffer sets the size of the operating system's transmit buffer associated with the connection.

func (*TCPConn) SetWriteDeadline

func (conn *TCPConn) SetWriteDeadline(t time.Time) error

SetWriteDeadline implements the Conn SetWriteDeadline method.

func (*TCPConn) WriteTo

func (conn *TCPConn) WriteTo(p []byte, addr net.Addr) (n int, err error)

WriteTo implements the PacketConn WriteTo method.
