Vl-stream

Change-vl-stream

Modifying constructor for vl-stream structures.

Syntax

(change-vl-stream x 
                  [:dir <dir>] 
                  [:size <size>] 
                  [:parts <parts>] 
                  [:atts <atts>])

This is an often useful alternative to make-vl-stream.

We construct a new vl-stream 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 defprod.
