33 ;; It handles the all aspects of startup once the C code has finished
|
|
|
34 ;; initializing itself. Entry from C is through the function set in
|
|
|
35 ;; the `top-level' variable, which is normally `normal-top-level'. At
|
|
|
36 ;; the point that `normal-top-level' has been invoked:
|
|
|
37 ;;
|
|
|
38 ;; (1) the dumped Elisp files are available. Either they were loaded
|
|
|
39 ;; during this invocation of temacs and it was then converted to
|
|
|
40 ;; XEmacs using the run-temacs mechanism, or (more likely) the
|
|
|
41 ;; loadup and dumping occurred at some point in the past and we
|
|
|
42 ;; just read in the dumped data.
|
|
|
43 ;;
|
|
|
44 ;; (2) All C subsystems have been initialized.
|
|
|
45 ;;
|
|
|
46 ;; (3) A "stream" device has been created, which does I/O over stdin
|
|
|
47 ;; and stdout. This is the only device we have available and our
|
|
|
48 ;; only means of communication, other than disk files.
|
|
|
49 ;;
|
|
|
50 ;; (4) The command-line arguments have been sorted according to
|
|
|
51 ;; priority specs (this implies that the names of all arguments
|
|
|
52 ;; must be hard-coded into emacs.c), and certain low-level
|
|
|
53 ;; arguments such as -sd, -t, -nd, -nw, -batch, etc. have been
|
|
|
54 ;; processed by main_1() and removed. (NOTE: main_1() is the name
|
|
|
55 ;; in the source code, but in the object file it has some other
|
|
|
56 ;; name, such as xemacs_21_2_34_mips_sgi_irix6().) Certain other
|
|
|
57 ;; arguments such as -version and -help are partially-processed,
|
|
|
58 ;; triggering some special behavior but being left on the list for
|
|
|
59 ;; further processing by the Lisp code.
