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 ¶ added in go1.15
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 ¶ added in go1.11
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 )
