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 BSwap32 ¶ added in v0.9.0
BSwap32 handles __builtin_bswap32(). It is not supported and if used with panic. The original documentation says:
Returns x with the order of the bytes reversed; for example, 0xaabb becomes 0xbbaa. Byte here always means exactly 8 bits.
func BSwap64 ¶ added in v0.9.0
BSwap64 handles __builtin_bswap64(). It is not supported, see BSwap32().
func BuiltinObjectSize ¶ added in v0.19.3
BuiltinObjectSize is for __builtin_object_size. https://github.com/elliotchance/c2go/issues/359
func BuiltinStrcpy ¶ added in v0.19.3
BuiltinStrcpy is for __builtin___strcpy_chk. https://opensource.apple.com/source/Libc/Libc-498/include/secure/_string.h
func BuiltinStrncpy ¶ added in v0.19.3
BuiltinStrncpy is for __builtin___strncpy_chk. https://opensource.apple.com/source/Libc/Libc-498/include/secure/_string.h
func IsType ¶ added in v0.9.0
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 :)
Types ¶
type CtRuneT ¶ added in v0.13.7
type CtRuneT int
CtRuneT represents __darwin_ct_rune_t.
type Double2 ¶
Double2 is used by the functions that end with "Stret". It replaces the internal macOS type of __double2.
func SincospiStret ¶
SincospiStret handles __sincospi_stret().
type Float2 ¶
Float2 is used by the functions that end with "Stret". It replaces the internal macOS type of __float2.
func SincospifStret ¶
SincospifStret handles __sincospif_stret().
