          SYNC(2)              INTERACTIVE UNIX System              SYNC(2)



          NAME
               sync - update super block

          SYNOPSIS
               void sync ( )

          DESCRIPTION
               The sync system call causes all information in memory that
               should be on disk to be written out.  This includes modified
               super blocks, modified inodes, and delayed block I/O.

               It should be used by programs which examine a file system,
               for example, fsck, df, etc.  It is mandatory before a re-
               boot.

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