Functions

func CopyFileRange

func CopyFileRange(rfd int, roff *int64, wfd int, woff *int64, len int, flags int) (n int, err error)

func Eaccess

func Eaccess(path string, mode uint32) error

func Fcntl

func Fcntl(fd int, cmd int, arg int) (int, error)

func Fstatat

func Fstatat(dirfd int, path string, stat *syscall.Stat_t, flags int) error

func GetRandom

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

GetRandom calls the getrandom system call.

func HasNonblockFlag

func RecvmsgInet4

func RecvmsgInet4(fd int, p, oob []byte, flags int, from *syscall.SockaddrInet4) (n, oobn int, recvflags int, err error)

func RecvmsgInet6

func RecvmsgInet6(fd int, p, oob []byte, flags int, from *syscall.SockaddrInet6) (n, oobn int, recvflags int, err error)

func SendmsgNInet4

func SendmsgNInet4(fd int, p, oob []byte, to *syscall.SockaddrInet4, flags int) (n int, err error)

func SendmsgNInet6

func SendmsgNInet6(fd int, p, oob []byte, to *syscall.SockaddrInet6, flags int) (n int, err error)

func SendtoInet4

func SendtoInet4(fd int, p []byte, flags int, to *syscall.SockaddrInet4) (err error)

func SendtoInet6

func Unlinkat

func Unlinkat(dirfd int, path string, flags int) error

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
)
