kernel

The kernel is the computer program at the core of the OS and is responsible for managing interactions with all hardware devices, such as terminals, databanks, scanners and so forth through device drivers; for handling inputs; for creating and terminating connections; for the execution of system calls; and for other basic system services.

Vars
max_users	The maximum number of users that may connect to the OS.
ping_accept	The number of cycles for which the kernel should reply to any pings made.
processing_drivers	A list of drivers that are open to receiving messages from the OS.
rescan_period	How often the mainframe should ping the network, in cycles.
rescan_timer	The current number of cycles until the mainframe should ping the network.
setup_progname_init	The default program name of the init program.
setup_progname_login	The default program name of the login program.
setup_progname_shell	The default program name of the shell.
sys_folder	The `/sys` directory that the kernel is located in.
users	A list of users currently connected to the OS, indexed by their user ID.
Procs
change_metadata	Alter the metadata of a specified file.
initialize_driver	Set up an individual driver, registering them for processing if necessary.
initialize_drivers	Initialise all drivers, setting up driver data and initialising them individually.
initialize_users	Initialise all users and user data, logging in connected terminals, and setting up home directories and user record files.
is_sysop	Check whether this user is a superuser.
login_temp_user	Log a connection in as a temporary user, starting the full login program, or logging in fully if a valid login record is provided.
login_user	Attempt to login as a full user, setting up a home directories and user record file if successful.
logout_user	Log a user out, terminating any running programs, and removing the user's record file.
message_all_users	Send a message to all logged in users.
