How do you write an abortable function?

Question

How do you wrote an abortable function, so that when user presses C-g during execution, this function is "stopped"

;; my function so far
(defun my/elfeed-extra-info-2 ()
  (interactive)
  (next-line)
  (message "here1")
  (sleep-for 0.5)
  (next-line)
  (message "here2")
  (sleep-for 0.5)
  (next-line)
  (message "here3")
  (sleep-for 0.5)
  (next-line)
  (message "here4")
  (sleep-for 0.5)
  (next-line)
  (message "here5")
  (sleep-for 0.5)
  (next-line)
  (message "here6")
  (sleep-for 0.5)
  (next-line)
  (message "here7")
  (sleep-for 0.5)
  (next-line)
  (message "here8")
  (sleep-for 0.5)
)
