How to use "yank" in an emacs lisp function?

Answer 1

You can access directly the kill-ring list to access the latest kill:

 (substring-no-properties (car kill-ring))

The substring-no-properties bit is important since text is kept in the kill ring with additional properties (like fontification specific to a particular mode and you'll probably want to strip those).
