:mrdocs:

Return a newly‐allocated block of memory of the specified `size` (in bytes). If `size` is 0, a null pointer is returned with no other effect (e.g., on allocation statistics). Otherwise, invoke the `allocate` method of the allocator supplied at construction, and increment the number of currently (and cumulatively) allocated bytes by `size`.
