25 ;; X-win.el: this file defines functions to initialize the X window
26 ;; system and process X-specific command line parameters before
27 ;; creating the first X frame.
29 ;; Beginning in Emacs 23, the act of loading this file should not have
30 ;; the side effect of initializing the window system or processing
31 ;; command line arguments (this file is now loaded in loadup.el). See
32 ;; `handle-args-function' and `window-system-initialization' for more details.
34 ;; startup.el will then examine startup files, and eventually call the hooks
35 ;; which create the first window(s).

131 When a session manager tells Emacs that the window system is shutting
132 down, this function is called. It calls the functions in the hook
133 `emacs-save-session-functions'. Functions are called with the current
134 buffer set to a temporary buffer. Functions should use `insert' to insert
135 lisp code to save the session state. The buffer is saved in a file in the
136 home directory of the user running Emacs. The file is evaluated when
137 Emacs is restarted by the session manager.
139 If any of the functions returns non-nil, no more functions are called
140 and this function returns non-nil. This will inform the session manager
141 that it should abort the window system shutdown."
