SYNC(2)                 COMMAND REFERENCE                 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.

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

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

SEE ALSO
     fsync(2), sync(8), and update(8).
