Error Codes Reference (AutoLISP)

 
 
 

The following table shows the values of error codes generated by AutoLISP. The ERRNO system variable is set to one of these values when an AutoLISP function call causes an error that AutoCAD detects. AutoLISP applications can inspect the current value of ERRNO with (getvar "errno").

The ERRNO system variable is not always cleared to zero. Unless it is inspected immediately after an AutoLISP function has reported an error, the error that its value indicates may be misleading. This variable is always cleared when starting or opening a drawing.

NoteThe possible values of ERRNO, and their meanings, are subject to change.
