NAME
ctrl_alt_del - routes the keyboard interrupt ctrl-alt-del key sequence
SYNOPSIS
linux/kernel/sys.c
void ctrl_alt_del(void);
DESCRIPTION
This simple routine tests the variable C_A_D for a true/false
condition. If it is true then a hard reset is done by the system.
Otherwise, a signal SIGINT is sent to the process with the process
ID 1, usually a program called init.
WARNINGS
This routine is in interrupt mode. It can not sync() your system.
Data loss may occur. It is recommended that you
configure your system to send a signal
to init, where you can control the shutdown.
NOTES
The default of this function is to do hard resets immediately.
