NAME

       gd_fragment_index — retrieve the fragment containing a dirfile field

SYNOPSIS

       #include <getdata.h>

       int gd_fragment_index(const DIRFILE *dirfile, const char *field_code);

DESCRIPTION

       The  gd_fragment_index()  function  queries a dirfile(5) database specified by dirfile and
       returns the index number of the fragment defining the field specified by  field_code.   If
       field_code contains a representation suffix, it will be ignored.

RETURN VALUE

       Upon  successful completion, gd_fragment_index() returns the requested fragment index.  On
       error, gd_fragment_index() returns -1 and sets the dirfile error a non-zero  error  value.
       Possible error values are:

       GD_E_BAD_DIRFILE
               The supplied dirfile was invalid.

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

       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).
