The third element is the function which actually start the process.
Several such hooks has been defined:
TeX-run-command: Start up the process and show the output in a
separate buffer. Check that there is not two commands running for the
same file. Return the process object.
TeX-run-format: As `TeX-run-command', but assume the output is created
by a TeX macro package. Return the process object.
TeX-run-TeX: For TeX output.
TeX-run-interactive: Run TeX or LaTeX interactively.
TeX-run-BibTeX: For BibTeX output.
TeX-run-Biber: For Biber output.
TeX-run-compile: Use `compile' to run the process.
TeX-run-shell: Use `shell-command' to run the process.
TeX-run-discard: Start the process in the background, discarding its
output.
TeX-run-background: Start the process in the background, show output
in other window.
TeX-run-silent: Start the process in the background.
TeX-run-discard-foreground: Start the process in the foreground,
discarding its output.
TeX-run-function: Execute the Lisp function or function call
specified by the string in the second element. Consequently,
this hook does not start a process.
TeX-run-discard-or-function: If the command is a Lisp function,
execute it as such, otherwise start the command as a process,
discarding its output.
To create your own hook, define a function taking three arguments: The
name of the command, the command string, and the name of the file to
process. It might be useful to use `TeX-run-command' in order to
create an asynchronous process.
If the fourth element is non-nil, the user will get a chance to
modify the expanded string.
The fifth element indicates in which mode(s) the command should be
present in the Command menu. Use t if it should be active in any
mode. If it should only be present in some modes, specify a list with
the respective mode names.
Any additional elements get just transferred to the respective menu entries."
