NAME
       sync2 - Flush file system metadata and data from memory buffers to disk

SYNOPSIS
       #include <sys/mount.h>

       int sync2 (
	    unsigned int POLICY ,
	    char *path);

STANDARDS
       Interfaces documented on this reference page conform to industry standards as follows:

       sync2():  XSH5.0

       Refer to the standards(5) reference page for more information about industry standards and associated tags.

PARAMETERS
       Flush the file system memory buffers to disk.  The argument is one of the following: Flush all memory buffers.  Specifying this flag causes
       the function to behave the same as the sync function.  See sync(2).  Flush all memory buffers except those under smooth sync control.   The
       name  of  a  file  system  or  fileset.	 Specify the optional path parameter when you want to have the POLICY act only on that file system
       instead of all file systems.  Specify a NULL argument when you want to have the POLICY act on all file systems.

DESCRIPTION
       The sync2 function causes file system data to be flushed (written) to disk.  Which memory buffers are flushed to disk depends on the POLICY
       argument.

       If  the	policy	is  SYNC_SYNCPOLICY,  all  memory buffers are flushed to disk.	If the policy is SYNC_SMOOTHSYNCPOLICY, all memory buffers
       except those under smooth sync control are flushed to disk.

       To which file systems the POLICY argument applies depends on the path argument.	To apply the policy to one file system,  name  it  in  the
       path argument.  To apply the policy to all file systems, specify the path argument as NULL.

       The writing, although scheduled, is not necessarily complete upon return from the sync2 function.
