Emacs/AUCTeX prefix arguments

In LaTeX mode C-c C-c is bound to:

(TeX-command-master &optional OVERRIDE-CONFIRM)

Normally this interactive function runs a command, perhaps a LaTeX compilation, asking for confirmation.

In tex-buf.el it reads:

If a prefix argument OVERRIDE-CONFIRM is given, confirmation will depend on it being positive instead of the entry in `TeX-command-list'.

This is a bit cryptic for me and reading C-h v TeX-command-list didn't help.

How can I pass the prefix argument to "TeX-command-master" so that I avoid all the confirmation requests?

Build & view

Again, this solution, instead of modifying the behaviour of the TeX-command-master, rewrites it. The rewritten version of the command, named build-view, follows a rather straightforward logic.

1. If the LaTeX file buffer is not-modified, it runs the default viewer;
2. If the buffer is dirty, it runs the default LaTeX compiler and, after the build, opens the output in the default viewer.

Here's the code:

(defun build-view ()
  (interactive)
  (if (buffer-modified-p)
      (progn  
    (let ((TeX-save-query nil)) 
    (TeX-save-document (TeX-master-file)))
    (setq build-proc (TeX-command "LaTeX" 'TeX-master-file -1))
    (set-process-sentinel  build-proc  'build-sentinel))
    (TeX-view)))

(defun build-sentinel (process event)    
  (if (string= event "finished\n") 
      (TeX-view)
    (message "Errors! Check with C-`")))

You can now type M-x build-view and start the told build-view process or associate it with a new keybinding such as “F2”:

(add-hook 'LaTeX-mode-hook '(lambda () (local-set-key (kbd "<f2>") 'build-view)))

Note: As suggested by Tyler, TeX-save-query variable is changed locally, therefore the old C-c C-c/ TeX-command-master is unaffected and will keep asking confirmations.

Do edit this code to make it better or easier to read!
