objc:objc-block-pointer

(objc:objc-block-pointer block)

The address of block's literal, an integer, or nil once objc:free-objc-block freed it. Rarely needed: an objc:objc-block passes where a block goes as it stands. Part of the macOS-only objc package -- the interpreter (java -jar, or the rontolisp native binary), a compiled .class / .jar and a --native executable for macOS on Apple silicon, never a .wasm; on a machine without the runtime it signals an error. See the macOS GUI guide.
