See :c:func:`array_size`, :c:func:`array3_size`, and :c:func:`struct_size`,
for more details as well as the related :c:func:`check_add_overflow` and
:c:func:`check_mul_overflow` family of functions.
For other calculations, please compose the use of the size_mul(),
size_add(), and size_sub() helpers. For example, in the case of::

Instead, use the helpers::
