Functions

func IO

func IO(typ, nr uint) uint

IO defines an ioctl with no parameters. It corresponds to _IO in the Linux userland API.

func IOR

func IOR(typ, nr, size uint) uint

IOR defines an ioctl with read (userland perspective) parameters. It corresponds to _IOR in the Linux userland API.

func IOW

func IOW(typ, nr, size uint) uint

IOW defines an ioctl with write (userland perspective) parameters. It corresponds to _IOW in the Linux userland API.

func IOWR

func IOWR(typ, nr, size uint) uint

IOWR defines an ioctl with both read and write parameters. It corresponds to _IOWR in the Linux userland API.

func Ioctl

func Ioctl(fd uintptr, op uintptr, arg uintptr) error
