HALTSYS(C)               XENIX System V                HALTSYS(C)



     Name
          haltsys, reboot - Closes out the file systems and shuts down
          the system.

     Syntax
          /etc/haltsys
          /etc/reboot

     Description
          The haltsys utility performs a uadmin() system call (see
          uadmin(S)) to flush out pending disk I/O, mark the file
          systems clean, and halt the processor.  haltsys takes effect
          immediately, so user processes should be killed beforehand.
          shutdown(C) is recommended for normal system shutdown, since
          it warns users, terminates processes, then calls haltsys.
          Use haltsys directly only if you cannot run shutdown; for
          example, because of some system problem.

          The reboot command performs the same function as haltsys,
          except the system is rebooted automatically afterwards.

     Notes
          haltsys locks hard disk heads.
