SYNC(2) — SYSTEM CALLS
NAME
sync − update super-block
SYNOPSIS
sync()
DESCRIPTION
sync() writes out all information in core memory that should be on disk. This includes modified super blocks, modified inodes, and delayed block I/O.
sync() should be used by programs that examine a file system, for example fsck(8), df(1V), etc. sync() is mandatory before a boot.

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