    NAME

    
    
    reboot
    
     - reboot system or halt processor
    
     
    

    LIBRARY

    Lb libc
    
     
    

    SYNOPSIS

       #include <unistd.h>
       #include <sys/reboot.h>
    int reboot (int howto);
     

    DESCRIPTION

    The reboot ();
    system call reboots the system. Only the super-user may reboot a machine on demand. However, a reboot is invoked automatically in the event of unrecoverable system failures.

    The Fa howto argument is a mask of options; the system call interface allows the following options, defined in the include file In sys/reboot.h , to be passed to the new kernel or the new bootstrap and init programs.

    RB_AUTOBOOT
    The default, causing the system to reboot in its usual fashion.
    RB_ASKNAME
    Interpreted by the bootstrap program itself, causing it to prompt on the console as to what file should be booted. Normally, the system is booted from the file ``xx (0,0)kernel '' where xx is the default disk name, without prompting for the file name.
    RB_DFLTROOT
    Use the compiled in root device. Normally, the system uses the device from which it was booted as the root device if possible. (The default behavior is dependent on the ability of the bootstrap program to determine the drive from which it was loaded, which is not possible on all systems.)
    RB_DUMP
    Dump kernel memory before rebooting; see savecore(8) for more information.
    RB_HALT
    the processor is simply halted; no reboot takes place. This option should be used with caution.
    RB_POWEROFF
    After halting, the shutdown code will do what it can to turn off the power. This requires hardware support.
    RB_INITNAME
    An option allowing the specification of an init program (see init(8)) other than /sbin/init to be run when the system reboots. This switch is not currently available.
    RB_KDB
    Load the symbol table and enable a built-in debugger in the system. This option will have no useful function if the kernel is not configured for debugging. Several other options have different meaning if combined with this option, although their use may not be possible via the reboot ();
    system call. See ddb(4) for more information.
    RB_NOSYNC
    Normally, the disks are sync'd (see sync(8)) before the processor is halted or rebooted. This option may be useful if file system changes have been made manually or if the processor is on fire.
    RB_RDONLY
    Initially mount the root file system read-only. This is currently the default, and this option has been deprecated.
    RB_SINGLE
    Normally, the reboot procedure involves an automatic disk consistency check and then multi-user operations. RB_SINGLE prevents this, booting the system with a single-user shell on the console. RB_SINGLE is actually interpreted by the init(8) program in the newly booted system.

    When no options are given (i.e., RB_AUTOBOOT is used), the system is rebooted from file ``kernel'' 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 normally performed (see fsck(8)).  

    RETURN VALUES

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

    ERRORS

    Bq Er EPERM
    The caller is not the super-user.

     

    SEE ALSO

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

    HISTORY

    The reboot ();
    system call appeared in BSD 4.0  

    BUGS

    The HP300 implementation supports neither RB_DFLTROOT nor RB_KDB
