gd_metaflush(3)			    GETDATA		       gd_metaflush(3)

NAME
       gd_metaflush — write modified dirfile metadata to disk

SYNOPSIS
       #include <getdata.h>

       int gd_metaflush(DIRFILE *dirfile);

DESCRIPTION
       The gd_metaflush() function flushes all pending metadata changes in the
       dirfile specified by dirfile to disk.  This is accomplished by re-writ‐
       ing  the	 format	 specification fragments containing modified metadata,
       overwriting the existing files.	Format file fragments  which  are  un‐
       changed are not touched.

       Metadata	 is  written  to  disk	using the current Standards Version as
       stored in the dirfile object.  See gd_dirfile_standards(3) to change or
       report the current Standards Version.  If the dirfile metadata conforms
       to no known Standards Version, a Standards non-compliant fragment  will
       be written.

       This  function flushes only metadata.  To flush the field data as well,
       call gd_sync(3) instead.

RETURN VALUE
       On success, zero is returned.  On error, -1 is returned and the dirfile
       error is set to a non-zero error value.	Possible error values are:

       GD_E_ACCMODE
	       The supplied dirfile was opened in read-only mode.

       GD_E_ALLOC
	       The library was unable to allocate memory.

       GD_E_BAD_DIRFILE
	       The supplied dirfile was invalid.

       GD_E_FLUSH
	       A  temporary  file  could not be opened into which to write the
	       modified metadata, or renaming  the  temporary  file  over  the
	       original fragment failed.

       The  dirfile error may be retrieved by calling gd_error(3).  A descrip‐
       tive error string for the last error encountered can be obtained from a
       call to gd_error_string(3).

BUGS
       When  writing metadata using Standards Version 4 or earlier, the refer‐
       ence field may change, owing to the lack of a /REFERENCE directive.   A
       work-around is to upgrade to Standards Version 5 or later.
