NAME

       reboot - reboot system or halt processor

SYNOPSIS

       #include <sys/reboot.h>

       int reboot(int howto, char *bootargs);

       The  reboot()  function	reboots  the  system.	The howto argument specifies the behavior of the system while rebooting and is a mask con-
       structed by a bitwise-inclusive-OR of flags from the following list:

       RB_AUTOBOOT     The machine is rebooted from the root filesystem on the default boot device. This is the default behavior. See boot(1M) and
		       kernel(1M).

       RB_HALT	       The processor is simply halted; no reboot takes place. This option should be used with caution.

       RB_ASKNAME      Interpreted by the bootstrap program and kernel, causing the user to be asked for pathnames during the bootstrap.

       RB_DUMP	       The  system  is	forced	to panic immediately without any further processing and a crash dump is written to the dump device
		       (see dumpadm(1M)) before rebooting.

       Any other howto argument causes the kernel file to boot.

       The interpretation of the bootargs argument is platform-dependent.

       Upon successful completion, reboot() never returns.  Otherwise, -1 is returned and errno is set to indicate the error.

       The reboot() function will fail if:

       EPERM	The {PRIV_SYS_CONFIG} privilege is not asserted in the effective set of the calling process.

NAME

       reboot - reboot system or halt processor

SYNOPSIS

       #include <sys/reboot.h>

       reboot(howto)
       int howto;

DESCRIPTION

       Reboot  reboots	the system, and is invoked automatically in the event of unrecoverable system failures.  Howto is a mask of options passed
       to the bootstrap program.  The system call interface permits only RB_HALT or RB_AUTOBOOT to be passed to  the  reboot  program;	the  other
       flags  are  used  in scripts stored on the console storage media, or used in manual bootstrap procedures.  When none of these options (e.g.
       RB_AUTOBOOT) is given, the system is rebooted from file "vmunix" in the root file system of unit 0 of a disk chosen in a processor specific
       way.  An automatic consistency check of the disks is then normally performed.

       The bits of howto are:

       RB_HALT
	      the processor is simply halted; no reboot takes place.  RB_HALT should be used with caution.

       RB_ASKNAME
	      Interpreted by the bootstrap program itself, causing it to inquire as to what file should be booted.  Normally, the system is booted
	      from the file "xx(0,0)vmunix" without asking.

       RB_SINGLE
	      Normally, the reboot procedure involves an automatic disk consistency check and then multi-user operations.  RB_SINGLE prevents  the
	      consistency  check,  rather  simply  booting  the  system  with a single-user shell on the console.  RB_SINGLE is interpreted by the
	      init(8) program in the newly booted system.  This switch is not available from the system call interface.

       Only the super-user may reboot a machine.

RETURN VALUES

       If successful, this call never returns.	Otherwise, a -1 is returned and an error is returned in the global variable errno.

ERRORS

       [EPERM]	      The caller is not the super-user.

SEE ALSO

       crash(8), halt(8), init(8), reboot(8)

BUGS

       The notion of ``console medium'', among other things, is specific to the VAX.
