array-total-size
array => size
array—an array.
size—a non-negative integer.
Returns the array total size of the array.
(array-total-size (make-array 4)) => 4 (array-total-size (make-array 4 :fill-pointer 2)) => 4 (array-total-size (make-array 0)) => 0 (array-total-size (make-array '(4 2))) => 8 (array-total-size (make-array '(4 0))) => 0 (array-total-size (make-array '())) => 1
Should signal an error of type type-error if its argument is not an array.
If the array is a vector with a fill pointer, the fill pointer is ignored when calculating the array total size.
Since the product of no arguments is one, the array total size of a zero-dimensional array is one.
(array-total-size x) == (apply #'* (array-dimensions x)) == (reduce #'* (array-dimensions x))
