      Empty-strin

      Create an empty strin-p structure.

      Signature
      (empty-strin) → *

      This is very unlikely to be useful to you. It exists only because we need an abstract strin-p corresponding to the initial sin$c.

      We just leave this enabled.

      Definitions and Theorems

      Function: empty-strin

      (defun empty-strin nil
        (declare (xargs :guard t))
        (let ((__function__ 'empty-strin))
          (declare (ignorable __function__))
          (make-strin :chars nil
                      :file ""
                      :line 1
                      :col 0)))
