ANSI Common Lisp 15 Arrays 15.2 Dictionary of Arrays
- Arguments and Values:
vector - a vector with a fill pointer.
element - an object.
Decreases the fill pointer of vector by one,
and retrieves the element of vector that is
designated by the new fill pointer.
(vector-push (setq fable (list 'fable))
(setq fa (make-array 8
:initial-element 'sisyphus))) 2
(fill-pointer fa) 3
(eq (vector-pop fa) fable) true
(vector-pop fa) SISYPHUS
(fill-pointer fa) 1
- Side Effects:
The fill pointer is decreased by one.
- Affected By:
The value of the fill pointer.
- Exceptional Situations:
An error of type type-error is signaled if vector does not have a fill pointer.
If the fill pointer is zero, vector-pop signals an error of type error.
