BOOT(9)			     OpenBSD Kernel Manual		       BOOT(9)

     boot - halt or reboot the system

     #include <sys/reboot.h>

     boot(int howto);

     The boot() function handles final system shutdown, and either halts or
     reboots the system.  The exact action to be taken is determined by the
     flags passed in howto and by whether or not the system has finished

     If the system has finished autoconfiguration, boot() does the following:

	   1.	Sets the boothowto system variable from the howto argument.

	   2.	If this is the first invocation of boot() and the RB_NOSYNC
		flag is not set in howto, syncs and unmounts the system disks
		by calling vfs_shutdown(9) and sets the time of day clock by
		calling resettodr(9).

	   3.	Disables interrupts.

	   4.	If rebooting after a crash (i.e., if RB_DUMP is set in howto,
		but RB_HALT is not), saves a system crash dump.

	   5.	Runs any shutdown hooks by calling doshutdownhooks(9).

	   6.	Prints a message indicating that the system is about to be
		halted or rebooted.

	   7.	If RB_HALT is set in howto, halts the system.  Otherwise,
		reboots the system.

     If the system has not finished autoconfiguration, boot() runs any
     shutdown hooks by calling doshutdownhooks(9), prints a message, and halts
     the system (unless RB_USERREQ is specified, in which case the system will
     be halted if RB_HALT is given, and rebooted otherwise; see reboot(2) for
     more details).
