SYNOPSIS

#include <getdata.h>

int gd_put_string(DIRFILE *dirfile, const char *field_code, const char *data_in);

DESCRIPTION

The gd_put_string() function queries a dirfile(5) database specified by dirfile and sets the STRING field_code , which should not contain a representation suffix, to the value specified in data_in.

The dirfile argument must point to a valid DIRFILE object previously created by a call to gd_open(3).

Because string values are stored in the dirfile metadata, the new value of field_code won't be written to disk until the dirfile metadata is flushed with gd_metaflush(3), or until the dirfile is closed.

RETURN VALUE

On success, gd_put_string() returns the length of the string stored, including the trailing NUL character. On error, it returns 0 and sets the dirfile error to a non-zero value. Possible error values are:

GD_E_ACCMODE

The specified dirfile was opened read-only.

GD_E_BAD_CODE

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

GD_E_BAD_DIRFILE

An invalid dirfile was supplied.

GD_E_BAD_FIELD_TYPE

The supplied field_code referred to a field of type other than STRING. The caller should use gd_putdata(3), gd_put_carray(3), or gd_put_constant(3) instead.

GD_E_BAD_TYPE

An invalid data_type was specified.

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.

GD_E_PROTECTED

The fragment containing the string was protected from change.

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