Value-pointer

Make-value-pointer

Basic constructor macro for value-pointer structures.

Syntax

(make-value-pointer [:core <core>] 
                    [:reftype <reftype>])

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

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

Definition

This is an ordinary make- macro introduced by fty::defprod.

Macro: make-value-pointer

(defmacro make-value-pointer (&rest args)
  (std::make-aggregate 'value-pointer
                       args '((:core) (:reftype))
                       'make-value-pointer
                       nil))

Function: value-pointer

(defun value-pointer (core reftype)
  (declare (xargs :guard (and (pointerp core) (typep reftype))))
  (declare (xargs :guard t))
  (let ((__function__ 'value-pointer))
    (declare (ignorable __function__))
    (b* ((core (mbe :logic (pointer-fix core)
                    :exec core))
         (reftype (mbe :logic (type-fix reftype)
                       :exec reftype)))
      (cons :pointer (list core reftype)))))
