org-get-outline-path
org-get-outline-path is a compiled Lisp function in `org.el
'.
(org-get-outline-path &optional FASTP LEVEL HEADING)
Return the outline path to the current entry, as a list.
The parameters FASTP, LEVEL, and HEADING are for use by a scanner
routine which makes outline path derivations for an entire file,
avoiding backtracing. Refile target collection makes use of that.
