Constants 

const (
	AT_EACCESS          = 0x200
	AT_FDCWD            = -0x64
	AT_REMOVEDIR        = 0x200
	AT_SYMLINK_NOFOLLOW = 0x100

	R_OK = 0x4
	W_OK = 0x2
	X_OK = 0x1
)

Variables 

var FcntlSyscall uintptr = syscall.SYS_FCNTL

FcntlSyscall is the number for the fcntl system call. This is usually SYS_FCNTL, but can be overridden to SYS_FCNTL64.

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 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 HasNonblockFlag(flag int) bool

func IsNonblock 

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

func KernelVersion 

func KernelVersion() (major, minor int)

KernelVersion returns major and minor kernel version numbers, parsed from the syscall.Uname's Release field, or 0, 0 if the version can't be obtained or parsed.

Currently only implemented for Linux.

func Openat 

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

func RecvfromInet4 

func RecvfromInet4(fd int, p []byte, flags int, from *syscall.SockaddrInet4) (int, error)

func RecvfromInet6 

func RecvfromInet6(fd int, p []byte, flags int, from *syscall.SockaddrInet6) (n int, err error)

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 SendtoInet6(fd int, p []byte, flags int, to *syscall.SockaddrInet6) (err 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
)
