reboot(3)               (BSD Compatibility Package)               reboot(3)


   NAME
         reboot - reboot system or halt processor

   SYNOPSIS
         cc [ flag... ] file ... -lucb

         #include <sys/reboot.h>

         reboot(howto, [ bootargs ] )
         int howto;
         char *bootargs;

   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
         RBHALT or RBAUTOBOOT 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
         instance RBAUTOBOOT) is given, the system is rebooted from file
         /stand/unix.  An automatic consistency check of the disks is then
         normally performed.

         The bits of howto that are used are:

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

         RBASKNAME     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
                        /stand/unix without asking.

   RETURN VALUE
         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.

   FILES
         /vmunix

   SEE ALSO

   NOTES
         Any other howto argument causes /stand/unix to boot.
