NAME¶
gd_put_string — retrieve a string from a dirfile databaseSYNOPSIS¶
#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.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_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), or gd_put_constant(3) instead.
- GD_E_BAD_REPR
- The representation suffix specified in field_code was not recognised.
- 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.
