> The function aligned_alloc() is the same as memalign(), except for the added restriction that size should be a multiple of alignment. So for a non-zero alignment size need to be non-zero.

I don't think the last part is true, 0 x Alignment = 0. That said, for non-zero sizes we know alignment holds, so this is fine.
