array-has-fill-pointer-p (Function)

Syntax:

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

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.
