Types

type SocketController

type SocketController interface {
	GetControl() func(network, addr string, c syscall.RawConn) (err error)
}

SocketController represents the socket listener controller.

func New

func New(flag SocketFlag, keepAlive int) SocketController

New returns the socket controller.

type SocketFlag

type SocketFlag uint

SocketFlag represents the flag to enable specific feature for the socket listener.
