:mrdocs:

Return the address of a contiguous block of memory of at least the specified `*size` (in bytes), and load the actual amount of memory allocated into `*size`. If `*size` is 0, return 0 with no effect. If the allocation request exceeds the remaining free memory space in the current internal buffer, use the allocator supplied at construction to allocate a new internal buffer, then allocate memory from the new buffer.
