This is the function:
http://workshop.pgrouting.org/chapters/wrapper.html#route-between-lat-lon-points-and-return-ordered-geometry-with-heading

As Steve mentioned, you will not be successful to copy pieces of code
(randomly) without understanding what actually is going on there.

The workshop really tries to explain everything, and I don't think it makes
sense to just copy the text from the link above. It should be all
explained. If you're missing some information, or something is unclear,
then feel free to ask.
