SYNOPSIS

9       sync( )
10

DESCRIPTION

12       Sync causes all information in core memory that should be on disk to be
13       written out.  This includes modified super  blocks,  modified  i-nodes,
14       and delayed block I/O.
15
16       It  should be used by programs which examine a file system, for example
17       icheck, df, etc.  It is mandatory before a boot.

BUGS

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