NAME

sync − update super-block

SYNTAX

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 i-nodes, and delayed block I/O.

Programs which examine a file system, for example, fsck or df, use the sync system call. The writing, although scheduled, is not necessarily complete upon return from sync.
