Constants

const AT_REMOVEDIR = 0x200

const AT_SYMLINK_NOFOLLOW = 0x100

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.

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
)
