NAME

sync − update super-block

SYNOPSIS

void sync ( )

DESCRIPTION

sync 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. 

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

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