func Alignof ¶

func Alignof[T any]() int

Alignof returns the alignment of type T in bytes.

alignof(T)

func Alloca ¶

func Alloca[T any](n int) *T

Alloca allocates an array of the given length on the stack and returns a pointer to it.

func Assert ¶

func Assert(cond bool, msg string)

Assert aborts the program with the given message if the condition is not true. If assertions are disabled, does nothing.

assert((cond) && msg)

func Bytes ¶

func Bytes(ptr *byte, n int) []byte

Bytes wraps a raw byte pointer and length into a []byte without copying. If ptr is nil, returns nil.

(so_Slice){ptr, n, n}

func PtrAdd ¶

func PtrAdd[T any](ptr *T, offset int) *T

PtrAdd adds offset bytes to a pointer and returns the result.

ptr + offset

func PtrAs ¶

func PtrAs[T any](ptr any) *T

PtrAs casts a raw pointer (void*) to *T.

(T*)(ptr)

func PtrAt ¶

func PtrAt[T any](ptr *T, index int) *T

PtrAt returns a pointer to the element at the given index in an array or slice.

&ptr[index]

func Raw ¶

func Raw(code string)

Raw emits a raw block of C code.

func Sizeof ¶

func Sizeof[T any]() int

Sizeof returns the size of type T in bytes.

sizeof(T)

func Slice ¶

func Slice[T any](ptr *T, len int, cap int) []T

Slice wraps a raw pointer and length into a []T without copying. If ptr is nil, returns nil.

(so_Slice){ptr, len, cap}

func String ¶

func String[T Char | ConstChar](ptr *T) string

String converts a null-terminated C string to a So string. If ptr is nil, returns "".

(so_String){s, strlen(s)}

func Val ¶

func Val[T any](expr string) T

Val emits a typed C expression.

func Zero ¶

func Zero[T any]() T

Zero returns the zero value of type T.
