initial commit 2020-10-13 08:37:53 +00:00			`#lang racket/base`

add demo of static binary ffi this adds a demo where the embedding C wrapper creates a new primitive module with an ffi table which can be accessed and used from the racket side to call functions, even when the runtime is hosted in a static binary 2020-10-14 22:17:24 +00:00			`(require ffi/unsafe)`
