     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.

     See Also
	  shutdn(S), uadmin(S), shutdown(C)
