Ulong-array

Change-ulong-array

Modifying constructor for ulong-array structures.

Syntax

(change-ulong-array x 
                    [:elemtype <elemtype>] 
                    [:elements <elements>])

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

We construct a new ulong-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

This is an ordinary change- macro introduced by fty::defprod.
