sync − update super-block
sync( )
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 example icheck, df, etc. It is mandatory before a boot.
sync(1), update(8)
The writing, although scheduled, is not necessarily complete upon return from sync.
(sync = 36.)
