sync

sync(2) 							   System Calls 							   sync(2)

NAME

       sync - update super block

SYNOPSIS

       #include <unistd.h>

       void sync(void);

DESCRIPTION

       The  sync() function writes all information in memory that should be on disk, including modified super blocks, modified inodes, and delayed
       block I/O.

       Unlike fsync(3C), which completes the writing before it returns, sync() schedules but does not  necessarily  complete  the  writing  before
       returning.

USAGE

       The  sync()  function  should  be  used	by  applications that examine a file system, such as fsck(1M), and df(1M), and is mandatory before
       rebooting.
