Jule Manual

Appearance

std/integ/c ​

Supplementer package for C interoperability of Integrated Jule. Provides helper API to make C interoperability easy and defines standards for common operations. Most C interoperable programs should use this package to make the program reliable and standardized. This is an elementary package to write C interoperable programs and packages with any scale.

DANGER

This package contains low-level implementations and is under the terms of the Unsafe Jule. Be careful using API of this package.

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 might 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
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
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.
