call-process problem

[Fabian Braennstroem]

Hi,

I would like to run a program with some arguments on the
current buffer. I would like to use call-process, because
the program has to run in background (even after closing emacs).

I actually tried some approaches using this function:

(defun fluent_journal ()
    "Runs FLUENT on Journal File"
    (interactive)
    (let ((bname2 (substring (buffer-name) 0 (string-match
"\\.jou" (buffer-name)))))
      (and
       (file-exists-p (concat bname2 ".jou"))
       ;(shell-command (concat "fluent 3d --version 6.3.26
-gu < " bname2 ".jou > & log_" bname2 " &"))
      ; (call-process "fluent" nil 0 nil "3d" "--version"
"6.3.26" "-gu" "<" bname2 ">" "&" "log"  ))
       (call-process "fluent" nil 0 nil "3d" "--version
6.3.26 -gu <" bname2 "> & log"  ))       ))

The actual call on a terminal looks like:
        fluent 3d --version 6.3.26 -gu < filename > & log

Does anyone know, how I have to define this 'call-process'?
Thanks!
Fabian
