NAME
reboot - reboot system or halt processor SYNOPSIS
#include <sys/reboot.h> int reboot(int howto, char *bootargs); DESCRIPTION
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. RETURN VALUES
Upon successful completion, reboot() never returns. Otherwise, -1 is returned and errno is set to indicate the error. ERRORS
The reboot() function will fail if: EPERM The {PRIV_SYS_CONFIG} privilege is not asserted in the effective set of the calling process. SEE ALSO

Name
       reboot - reboot system or halt processor

Syntax
       #include <sys/reboot.h>

       reboot(howto)
       int howto;

Arguments
       howto   The howto argument is a mask of options passed to the bootstrap program.

	       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  pre-
		      vents  the consistency check, rather simply booting the system with a single-user shell on the console.  RB_SINGLE is inter-
		      preted by the init(8) program in the newly booted system.  This switch is not available from the system call interface.

	       Only the superuser may a machine.

Description
       The system call reboots the system, and is invoked automatically in the event of unrecoverable system failures.	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 (for example, RB_AUTOBOOT) is given, the system is rebooted  from
       file in the root file system of unit 0 of a disk chosen in a processor-specific way.  Normally, an automatic consistency check of the disks
       is then performed.

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

Diagnostics
       The call fails under the following condition:

       [EPERM]	      The caller is not the superuser.
