SYNC(2)                 GENIX Programmer's Manual                 SYNC(2)



      NAME
           sync - update super-block

      SYNOPSIS
           sync()

      DESCRIPTION
           Sync causes all information in core memory that should be on disk to
           be  written  out.   This includes modified super blocks, modified i-
           nodes, and delayed block I/O.

           It should be used by programs which examine a file system, for exam-
           ple icheck, df, etc.  It is mandatory before a boot.

      SEE ALSO
           sync(1), update(8)

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