NAME
       sync, lsync - update disk

SYNOPSIS
DESCRIPTION
       causes  all  information in memory that should be on disk to be written
       out.  This includes modified file system meta-data  and	delayed	 block
       I/O.

       It  should be used by commands and programs that examine a file system,
       such as and so on.  It is mandatory before a shutdown.

       The writing, although  scheduled,  is  not  necessarily	complete  upon
       return from

       In  some HP-UX systems, may be reduced to a no-op.  This is permissible
       on a system which does not cache buffers or in a system	that  in  some
       way ensures that the disks are always in a consistent state.

       is a deprecated system call that is currently functionally identical to
       HP-UX kernel support for it remains only to aid compatibility with very
       old HP-UX binaries.
