SYNOPSIS
#include <getdata.h>- size_t gd_carray_len(DIRFILE *dirfile, const char *field_code);
DESCRIPTION
The dirfile argument must point to a valid DIRFILE object previously created by a call to gd_open(3).
RETURN VALUE
Upon successful completion, gd_carray_len() returns the length of the field specified. On error, it returns zero and sets the dirfile error 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_FIELD_TYPE
- The field specified by field_code was not of CARRAY type.
- GD_E_BAD_REPR
- The representation suffix specified in field_code was not recognised.
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).
