/*
 * Sample program for sync system call  - No.35
 *
 * sync - commit buffer chache to disk
 *
 * Synopsis
 *     #include <unistd.h>
 *
 *     void sync(void);
 *
 * Description
 *     sync first commits inodes to buffers, and then buffers to disk.
 *
 *     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 that examine a file system, such as
 *     fsck, df, etc.  It is mandatory before a re-boot.
 *
 *     The writing, although scheduled, is not necessarily completed before
 *     sync returns.  The fsync system call completes the writing before it
 *     returns.
