Syntax:
vector-pop vector => element
Arguments and Values:
vector---a vector with a fill pointer.
element---an object.
Description:
Decreases the fill pointer of vector by one, and retrieves the element of vector that is designated by the new fill pointer.
Examples:
(vector-push (setq fable (list 'fable))
(setq fa (make-array 8
:fill-pointer 2
: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.
