Scratchobj-cinst

Make-scratchobj-cinst

Basic constructor macro for scratchobj-cinst structures.

Syntax

(make-scratchobj-cinst [:val <val>])

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

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