Functions ¶

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

func IsNonblock ¶

func IsNonblock(fd int) (nonblocking bool, err error)

func Openat ¶

func Openat(dirfd int, path string, flags int, perm uint32) (int, error)

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
)
