Vl-struct

Make-vl-struct

Basic constructor macro for vl-struct structures.

Syntax

(make-vl-struct [:members <members>] 
                [:packedp <packedp>] 
                [:pdims <pdims>] 
                [:udims <udims>] 
                [:signedp <signedp>])

This is the usual way to construct vl-struct structures. It simply conses together a structure with the specified fields.

This macro generates a new vl-struct structure from scratch. See also change-vl-struct, which can "change" an existing structure, instead.

Definition

This is an ordinary make- macro introduced by defprod.

Macro: make-vl-struct

(defmacro make-vl-struct (&rest args)
  (std::make-aggregate 'vl-struct
                       args
                       '((:members)
                         (:packedp)
                         (:pdims)
                         (:udims)
                         (:signedp))
                       'make-vl-struct
                       nil))
