NAME
put_string --- retrieve a string from a dirfile databaseSYNOPSIS
#include <getdata.h>- int put_string(DIRFILE *dirfile, const char *field_code, const char *data_in);
DESCRIPTION
- The put_string() function queries a dirfile(5) database specified by dirfile and sets the STRING field_code to the value specified in data_in.
The dirfile argument must point to a valid DIRFILE object previously created by a call to dirfile_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 dirfile_metaflush(3), or until the dirfile is closed.
RETURN VALUE
On success, put_string() returns the length of the string stored, including the trailing NULL 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 putdata(3), or 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 get_error(3). A descriptive error string for the last error encountered may be obtained from a call to get_error_string(3).
