Functions

func GetRandom

func GetRandom(p []byte, flags GetRandomFlag) (n int, err error)

GetRandom calls the Linux getrandom system call. See https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=c6e9d6f38894798696f23c8084ca7edbf16ee895

func Getpeername

func Getpeername(s int, addr []byte) error

Getpeername copies the binary encoding of the peer address for s into addr.

func Getsockname

func Getsockname(s int, addr []byte) error

Getsockname copies the binary encoding of the current address for s into addr.

func Recvfrom

func Recvfrom(s int, b []byte, flags int, addr []byte) (int, error)

Recvfrom receives a message from s, copying the message into b. The socket address addr must be large enough for storing the source address of the message. Flags must be operation control flags or 0. It retunrs the number of bytes copied into b.

func Sendto

func Sendto(s int, b []byte, flags int, addr []byte) (int, error)

Sendto sends a message to the socket address addr, copying the message from b. The socket address addr must be suitable for s. Flags must be operation control flags or 0. It retunrs the number of bytes copied from b.

Types

type GetRandomFlag

type GetRandomFlag uintptr

GetRandomFlag is a flag supported by the getrandom system call.

const (
	// GRND_NONBLOCK means return EAGAIN rather than blocking.
	GRND_NONBLOCK GetRandomFlag = 0x0001

	// GRND_RANDOM means use the /dev/random pool instead of /dev/urandom.
	GRND_RANDOM GetRandomFlag = 0x0002
)
