(v13) Configuration device routines

This page applies to Harlequin v13.1r0 and later; and to Harlequin Core but not Harlequin MultiRIP

The configuration device need implement only the open_file , close_file , read_file , bytes_file , and last_error routines. The last_error routine is not needed if the other routines never return errors.

It may be useful to implement some of the other routines; a common choice is to implement the write_file routine to have somewhere to send output during the execution of the PostScript language text read from %config% .
