Long-array

Change-long-array

Modifying constructor for long-array structures.

Syntax

(change-long-array x 
                   [:components <components>])

This is an often useful alternative to make-long-array.

We construct a new long-array structure that is a copy of x, except that you can explicitly change some particular fields. Any fields you don't mention just keep their values from x.

Definition
