)

Apple defines a bunch of magic values for the type of character, see https://opensource.apple.com/source/Libc/Libc-320/include/ctype.h.auto.html

These are provided as values for method that take _f parameter.

Functions

func AssertRtn

func AssertRtn(functionName, filePath string, lineNumber int, expression string) bool

func BSwap32

func BSwap32(a uint32) uint32

I'm not sure which header file this actually comes from?

func BSwap64

func BSwap64(a uint64) uint64

I'm not sure which header file this actually comes from?

func BuiltinExpect

func BuiltinExpect(a, b int) bool

func Fabs

func Fabs(x float64) float64

func Fabsf

func Fabsf(x float32) float32

func Fabsl

func Fabsl(x float64) float64

func Inf

func Inf() float64

func Inff

func Inff() float32

func Infl

func Infl() float64

func IsType

func IsType(_c Darwin_ct_rune_t, _f uint32) uint32

IsType replaces __istype(). It should not be strictly necessary but the real __istype() refers to internal darwin state (_DefaultRuneLocale) that is difficult to translate. So for now we will replace it but this could be removed in the future.

There may be multiple bit masks. And yes, I'm sure there is a much better way to handle this, so if you know one please consider putting in a PR :)

func Putchar

func Putchar(character int)

Types

type C__mbstate_t

type C__mbstate_t int64

FIXME: These are wrong.

type Darwin_ct_rune_t

type Darwin_ct_rune_t int

__darwin_ct_rune_t

func IsCType

func IsCType(_c Darwin_ct_rune_t, _f uint32) Darwin_ct_rune_t

__darwin_ct_rune_t __isctype(__darwin_ct_rune_t, uint32)

func MaskRune

func MaskRune(_c Darwin_ct_rune_t, _f uint32) Darwin_ct_rune_t

I have no idea what MaskRune is supposed to do. It is provided internally by darwin.

func ToLower

func ToLower(_c Darwin_ct_rune_t) Darwin_ct_rune_t

func ToUpper

func ToUpper(_c Darwin_ct_rune_t) Darwin_ct_rune_t

type Double2

	Sinval float64
	Cosval float64
}

func SincosStret
