sync(2)                                                      sync(2)


       NAME
             sync - update super block

       SYNOPSIS
             #include <unistd.h>
             void sync(void);

       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.

             The writing, although scheduled, is not necessarily completed
             before sync returns.  The fsync system call completes the
             writing before it returns.

       USAGE
             sync should be used by programs that examine a file system,
             such as fsck(1M), df(1M), and so on.  It is mandatory before a
             re-boot.
