ANSI Common Lisp 15 Arrays 15.2 Dictionary of Arrays

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

Exceptional Situations:

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

See Also:

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.
