DESCRIPTION
       The sync() function causes all information in memory that should be on disk to be written out. The writing, although scheduled, is not nec-
       essarily complete upon return from the sync() function.	Types of information to be written  include  modified  superblocks,  inodes,  data
       blocks, and indirect blocks.

       The sync() function should be used by programs that examine a file system, such as the df command and the fsck command.
