     DESCRIPTION
     DESCRIPTION
          Fsync causes all modified data and attributes of fd to be
          moved to a permanent storage device.  This normally results
          in all in-core modified copies of buffers for the associated
          file to be written to a disc.

          Fsync should be used by programs which require a file to be
          in a known state; for example in building a simple
          transaction facility.
