NAME

       gd_carray_len — returns the length of a CARRAY field in a dirfile

SYNOPSIS

       #include <getdata.h>

       size_t gd_carray_len(DIRFILE *dirfile, const char *field_code);

DESCRIPTION

       The gd_carray_len() function queries a dirfile(5) database specified by dirfile and returns the number of
       length  of the CARRAY field field_code.  If field_code contains a valid representation suffix, it will be
       ignored.

       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  re‐
       turns 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).
