Error

Make-error

Basic constructor macro for error structures.

Syntax

(make-error [:info <info>])

This is the usual way to construct error structures. It simply conses together a structure with the specified fields.

This macro generates a new error structure from scratch. See also change-error, which can "change" an existing structure, instead.

Definition

                       nil))
