C-char-char

Make-c-char-char

Basic constructor macro for c-char-char structures.

Syntax

(make-c-char-char [:code <code>])

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

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