What is full name in trainspotting?

It's not entirely clear what you mean by "full name" in the context of Trainspotting. Could you please clarify your question? Do you mean:

* The full name of the protagonist? The main character in Trainspotting is Mark Renton, but his full name is never explicitly given in the book or film.

* The full name of the movie? The full name of the movie is simply Trainspotting, and it is based on the novel of the same name by Irvine Welsh.

* The full name of the author? The full name of the author of the book is Irvine Welsh.

Please let me know which of these you are referring to, or if you have something else in mind.
