Function-output

Change-function-output

Modifying constructor for function-output structures.

Syntax

(change-function-output x 
                        [:reg <reg>] 
                        [:type <type>])

This is an often useful alternative to make-function-output.

We construct a new function-output 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
