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).
