Fundef

Change-fundef

Modifying constructor for fundef structures.

Syntax

(change-fundef x 
               [:extension <extension>] 
               [:specs <specs>] 
               [:declor <declor>] 
               [:asm? <asm?>] 
               [:attribs <attribs>] 
               [:declons <declons>] 
               [:body <body>] 
               [:info <info>])

This is an often useful alternative to make-fundef.

We construct a new fundef 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
