Type-pointer

Make-type-pointer

Basic constructor macro for type-pointer structures.

Syntax

(make-type-pointer [:to <to>])

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

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