Memory allocation

.malloc

C.malloc(size: num) -> ptr

Allocate memory block

Params (1)

size

Size of memory block, in bytes.

Return value

On success, a pointer to the memory block allocated by the function.

If size is zero or the function failed to allocate the requested block of memory, null is returned.

.calloc

C.calloc(count: num, size: num) -> ptr

Allocate and zero-initialize array

Params (2)

count

Number of elements to allocate.

size

Size of each element.

Return value

Like C.malloc, but the returned memory block is zero-initialized.

.realloc

C.realloc(addr: ptr, size: num) -> ptr

Reallocate memory block

Params (2)

addr

Pointer to a memory block previously allocated with C.malloc, C.calloc or C.realloc.

If this is a null pointer, the function works like C.malloc.

size

• New size for the memory block, in bytes.

Return value

See C.malloc.

.free

C.free(addr: ptr)

Deallocate memory block

Parameters (1)

addr

A block of memory previously allocated by a call to C.malloc, C.calloc or C.realloc is deallocated, making it available again for further allocations.

Return value

None.

Must free pointers created by malloc, calloc and realloc to avoid memory leaks.

Do not free any pointer is freed or not formed by malloc, calloc and realloc.
