Function ARRAY-HAS-FILL-POINTER-P

Syntax:

array-has-fill-pointer-p array => generalized-boolean

Arguments and Values:

array---an array.

generalized-boolean---a generalized boolean.

Description:

Returns true if array has a fill pointer; otherwise returns false.

Examples:

     (array-has-fill-pointer-p (make-array 4)) =>  implementation-dependent
     (array-has-fill-pointer-p (make-array '(2 3))) =>  false
     (array-has-fill-pointer-p
       (make-array 8
                   :fill-pointer 2
                   :initial-element 'filler)) =>  true

Affected By: None.

Exceptional Situations:

Should signal an error of type type-error if its argument is not an array.

make-array, fill-pointer

Notes:

Since arrays of rank other than one cannot have a fill pointer, array-has-fill-pointer-p always returns nil when its argument is such an array.
