REBOOT(2)							     REBOOT(2)

NAME
       reboot - close down the system or reboot

SYNTAX
       #define _MINIX_SOURCE 1

       #include <unistd.h>

       int reboot(int how)

DESCRIPTION
       Reboot()	 is  used to close down the system.  It allows several ways of
       shutting down depending on how:

       reboot(RBT_DEFAULT)
	    Default shut-down action, the same as used	when  CTRL+ALT+DEL  is
	    pressed on the keyboard.

       reboot(RBT_HALT)
	    Halt the system.

       reboot(RBT_PANIC)
	    Cause  a  system panic.  This is not normally done from user mode,
	    but by servers using the sys_abort() kernel call.

       reboot(RBT_POWEROFF)
	    Power off the system if possible, reset otherwise.

       reboot(RBT_REBOOT)
	    Reboot the system with a software reset (currently not  supported,
	    so a hardware reset is used).

       reboot(RBT_RESET)
	    Reboot the system with a hardware reset.

       Reboot() may only be executed by the super-user.

DIAGNOSTICS
       If  the	call succeeds, it never returns.  If something went wrong, the
       return value is -1 and an error is indicated by errno.

SEE ALSO
       shutdown(8), reboot(8), halt(8), sync(2).
