"Post compile hook" in auctex

Question

How can I make emacs execute a script every time when a latex-compilation (via auctex and latexmk) finished successfully? In particular I want to send a SIGHUP signal to mupdf to make it reload my pdf file.

I know that the sighup can be send when using latexmk from commandline with -pvc option and that in this case also a general post compile hook is supported (https://tex.stackexchange.com/questions/299822/post-compile-hook-latexmk), however latexmk -pvc doesn't integrate well in auctex (https://github.com/tom-tan/auctex-latexmk/pull/11), so I am looking for an emacs way for a post compile hook.

You can use TeX-after-compilation-finished-functions, as the name suggests it can be used to run functions after the compilation finished successfully. This is its docstring:

Hook being run after TeX/LaTeX/ConTeXt finished successfully. The functions in this hook are run with the DVI/PDF output file given as argument. Using this hook can be useful for updating the viewer automatically after re-compilation of the document.

If you use an emacs-internal viewer such as doc-view-mode or pdf-view-mode, add TeX-revert-document-buffer to this hook.
