NAME
       sync - Update all file systems

SYNOPSIS
       #include <unistd.h>

       void sync(
	       void );

STANDARDS
       Interfaces  documented on this reference page conform to industry stan‐
       dards as follows:

       sync(): XSH4.2, XSH5.0

       Refer to the standards(5) reference page	 for  more  information	 about

DESCRIPTION
       The  sync() function causes all information in memory that should be on
       disk to be written out. The writing, although scheduled, is not	neces‐
       sarily complete upon return from the sync() function. Types of informa‐
       tion to be written include modified superblocks, inodes,	 data  blocks,
       and indirect blocks.

       The sync() function should be used by programs that examine a file sys‐
       tem, such as the df and fsck commands.
