NAME
       gd_flush -- write all pending dirfile changes to disk.

SYNOPSIS
       #include <getdata.h>

       int gd_flush(DIRFILE *dirfile, const char *field_code);

DESCRIPTION
       The  gd_flush()	function  flushes  and	closes	all  file handles associated with field_code, or its input(s), in the dirfile specified by
       dirfile.  If the field_code contains a valid representation suffix, it will be ignored.	As a special case,  if	field_code  is	NULL,  all
       fields  in  dirfile will be flushed and closed.	In this special case, modified metadata will also be flushed to disk as if gd_metaflush(3)
       had been called.

       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.

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_BAD_CODE
	       The field specified by field_code was not found in the database.

       GD_E_BAD_DIRFILE
	       The supplied dirfile was invalid.

       GD_E_BAD_REPR
	       The representation suffix specified in field_code was not recognised.

       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.  Only returned when field_code is NULL.

       GD_E_RAW_IO
	       An error occurred while trying to flush or close the field(s).

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