Package

Arguments

on

A boolean.

Description

The function set-make-instance-initarg-checking provides control over whether make-instance checks its initialization arguments.

Calling set-make-instance-initarg-checking with on true, causes make-instance to check the initargs. This is the initial state of LispWorks.

Initarg checking is switched off globally and dynamically by
(set-make-instance-initarg-checking nil) .

Notes

The effect of calling set-make-instance-initarg-checking can be overridden in a runtime by the deliver argument :make-instance-keyword-check . See the LispWorks Delivery User Guide for details.
