Functions

func SetIPv6Only

func SetIPv6Only(fd, ipv6only int) error

SetIPv6Only restricts a IPv6 socket to only process IPv6 requests or both IPv4 and IPv6 requests.

func SetKeepAlive

func SetKeepAlive(fd, secs int) error

SetKeepAlive sets whether the operating system should send keep-alive messages on the connection and sets period between keep-alive's.

func SetNoDelay

func SetNoDelay(fd, noDelay int) error

SetNoDelay controls whether the operating system should delay packet transmission in hopes of sending fewer packets (Nagle's algorithm).

The default is true (no delay), meaning that data is sent as soon as possible after a Write.

func SetRecvBuffer

func SetRecvBuffer(fd, size int) error

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

func SetReuseport

func SetReuseport(fd, reusePort int) error

SetReuseport enables SO_REUSEPORT option on socket.

func SetSendBuffer

func SetSendBuffer(fd, size int) error

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

func SockaddrToTCPOrUnixAddr

func SockaddrToTCPOrUnixAddr(sa unix.Sockaddr) net.Addr

SockaddrToTCPOrUnixAddr converts a Sockaddr to a net.TCPAddr or net.UnixAddr. Returns nil if conversion fails.

func SockaddrToUDPAddr

func SockaddrToUDPAddr(sa unix.Sockaddr) net.Addr

SockaddrToUDPAddr converts a Sockaddr to a net.UDPAddr Returns nil if conversion fails.

func SysConnect

func SysConnect(proto, addr string, sockopts ...Option) (fd int, sockaddr unix.Sockaddr, err error)

func TCPSocket

func TCPSocket(proto, addr string, sockopts ...Option) (int, net.Addr, error)

TCPSocket calls the internal tcpSocket.

func UDPSocket

func UDPSocket(proto, addr string, sockopts ...Option) (int, net.Addr, error)

UDPSocket calls the internal udpSocket.

func UnixSocket

func UnixSocket(proto, addr string, sockopts ...Option) (int, net.Addr, error)

UnixSocket calls the internal udsSocket.

Types

type Option

type Option struct {
	SetSockopt func(int, int) error
	Opt        int
}

Option is used for setting an option on socket.
