Malloc ​

jule
fn Malloc(size: uint): *unsafe

Allocates size bytes of memory. Memory does not initialize. Returns pointer to allocation if success, nil if not.

This function is part of the C-style memory management. It can be very dangerous.

Calloc ​

jule
fn Calloc(size: uint, n: uint): *unsafe

Allocates n elements of size bytes each, all initialized to zero. Returns pointer to allocation if success, nil if not.

This function is part of the C-style memory management. It can be very dangerous.

Realloc ​

jule
unsafe fn Realloc(mut ptr: *unsafe, size: uint): *unsafe

Re-allocates the previously allocated block in ptr, making the new block size bytes long. Returns pointer to allocation if success, nil if not.

This function is part of the C-style memory management. It can be very dangerous.

Free ​

jule
unsafe fn Free(mut ptr: *unsafe)

Free a block allocated by malloc, realloc or calloc. ptr is not set as nil by function, therefore ptr is dangling after free. Set ptr as nil after free for more safety.

This function is part of the C-style memory management. It can be very dangerous.

New ​

jule
fn New[T](): *T

Allocates new memory. Equivalent to: new T in C++

NewArray ​

jule
fn NewArray[T](size: int): *T

Allocates new array memory. Equivalent to: new T[size] in C++

Delete ​

jule
unsafe fn Delete[T](heap: *T)

Deallocates memory allocation. Equivalent to: delete heap in C++

DeleteArray ​

jule
unsafe fn DeleteArray[T](heap: *T)

Deallocates array memory allocation. Equivalent to: delete[] heap in C++

UTF16FromStr ​

jule
fn UTF16FromStr(s: str): []u16

Returns the UTF-16 encoding of the UTF-8 string s, with a terminating NULL added. If s includes NULL character at any location, ignores followed characters.

UTF16ToStr ​

jule
fn UTF16ToStr(s: []u16): str

Returns the UTF-8 encoding of the UTF-16 sequence s, with a terminating NULL removed. Returns empty string if s is nil.

U16PtrToStr ​

jule
unsafe fn U16PtrToStr(s: *u16): str

Returns the UTF-8 encoding of the UTF-16 sequence s in *u16 form, with a terminating NULL removed. Returns empty string if s is nil.

BytePtrToStr ​

jule
unsafe fn BytePtrToStr(s: *byte): str

Returns the string of s, with a terminating NULL removed. Returns empty string if pointer is nil.

StrToBytes ​

jule
fn StrToBytes(s: str): []byte

Returns s as NULL terminated byte slice which is able to be used safely as NULL terminated string pointer. If s contatins NULL termination at any location, accepts NULL termination is the end of s and skips following bytes.
