Mark the Emacs daemon as being initialized.
This finishes the daemonization process by doing the other half of detaching
from the parent process and its tty file descriptors.

Return non-nil if the current emacs process is a daemon.
If the daemon was given a name argument, return that name.

Dump current state of Emacs into executable file FILENAME.
Take symbols from SYMFILE (presumably the file you executed to run Emacs).
This is used in the file `loadup.el' when building Emacs.

You must run Emacs in batch mode in order to dump it.

Return the directory name in which the Emacs executable was located.

Return the program name that was used to run Emacs.
Any directory names are omitted.

Exit the Emacs job and kill it.
If ARG is an integer, return ARG as the exit program code.
If ARG is a string, stuff it as keyboard input.

This function is called upon receipt of the signals SIGTERM
or SIGHUP, and upon SIGINT in batch mode.

The value of `kill-emacs-hook', if not void,
is a list of functions (of no args),
all of which are called before Emacs is actually killed.
