gd_flush(3) GETDATA gd_flush(3) 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). SEE ALSO

gd_rewrite_fragment -- re-write a dirfile format specification fragment SYNOPSIS
#include <getdata.h> int gd_rewrite_fragment(DIRFILE *dirfile, int fragment); DESCRIPTION
The gd_rewrite_fragment() writes the format specification fragment specified by fragment to disk, regardless of whether it has changed or not, overwriting the existing file. In addition to being simply a valid fragment index, fragment may also be the special value GD_ALL_FRAGMENTS, which indicates that all frag- ments should be rewritten. 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_ACCMODE The supplied dirfile was opened in read-only mode. GD_E_BAD_DIRFILE The supplied dirfile was invalid. GD_E_BAD_INDEX The supplied fragment index was out of range. 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. GD_E_INTERNAL_ERROR An internal error occurred in the library while trying to perform the task. This indicates a bug in the library. Please report the incident to the maintainer. 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). BUGS
When writing metadata using Standards Version 4 or earlier, the reference field may change, owing to the lack of a /REFERENCE directive. A work-around is to upgrade to Standards Version 5 or later. SEE ALSO
