Hex-integer-literal

Make-hex-integer-literal

Basic constructor macro for hex-integer-literal structures.

Syntax

(make-hex-integer-literal [:digits/uscores <digits/uscores>] 
                          [:prefix-upcase-p <prefix-upcase-p>] 
                          [:suffix? <suffix?>])

This is the usual way to construct hex-integer-literal structures. It simply conses together a structure with the specified fields.

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

Definition

This is an ordinary make- macro introduced by fty::defprod.
