8.1. The options for DEFSTRUCT

8.1.1. The :PRINT-FUNCTION option
8.1.2. The :INHERIT option

8.1.1. The :PRINT-FUNCTION option

The :PRINT-FUNCTION option should contain a lambda expression (LAMBDA (object stream depth) (declare (ignore depth)) ...) This lambda expression names a FUNCTION whose task is to output the external representation of the STRUCTURE-OBJECT object onto the STREAM stream. This may be done by outputting text onto the stream using WRITE-CHAR, WRITE-STRING, WRITE, PRIN1, PRINC, PRINT, PPRINT, FORMAT and the like. The following rules must be obeyed:

8.1.2. The :INHERIT option
