Somebody asked for the docs to tell explicitly that this function was 
about disk caches, not DOS buffers.  Here's the patch:

  @subheading Description
  
  Attempts to update the disk with the data cached in the write-behind
! disk caches (such as @code{SmartDrv} and the built-in Windows 95 disk
! cache).
! 
! Note that this does @strong{not} flushes the DOS buffers.  You need to
! call @code{fsync} (@pxref{fsync}) or @code{close} (@pxref{close}) to
! force DOS to commit the file data to the disk; @code{sync}
! (@pxref{sync}) does that for all open files.
  
  @subheading Return Value
  
  None.

+ @subheading Example

+   sync ();
+   _flush_disk_cache ();
+ @end example
