Expr-va-arg

Make-expr-va-arg

Basic constructor macro for expr-va-arg structures.

Syntax

(make-expr-va-arg [:list <list>] 
                  [:type <type>])

This is the usual way to construct expr-va-arg structures. It simply conses together a structure with the specified fields.

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

Definition

                       args '((:list) (:type))
                       'make-expr-va-arg
                       nil))

Function: expr-va-arg

(defun expr-va-arg (list type)
  (declare (xargs :guard (and (exprp list) (tynamep type))))
  (declare (xargs :guard t))
  (let ((__function__ 'expr-va-arg))
    (declare (ignorable __function__))
    (b* ((list (mbe :logic (expr-fix list) :exec list))
         (type (mbe :logic (tyname-fix type)
                    :exec type)))
      (cons :va-arg (list list type)))))
