Paramdecl

Change-paramdecl

Modifying constructor for paramdecl structures.

Syntax

(change-paramdecl x 
                  [:spec <spec>] 
                  [:decl <decl>])

This is an often useful alternative to make-paramdecl.

We construct a new paramdecl 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.

Macro: change-paramdecl

                           (:decl . paramdecl->decl))
                         'change-paramdecl
                         'nil))
