The scheme/foreign library re-exports ffi/unsafe, ffi/unsafe/cvector, and ffi/vector, except that unsafe! must be used to import the unsafe bindings of ffi/unsafe and ffi/unsafe/cvector.
Makes unsafe bindings available.
(provide* provide-star-spec ...)
provide-star-spec = (unsafe id) | (unsafe (rename-out [id external-id])) | provide-spec
Like provide, but ids under unsafe are not actually provided. Instead, they are collected for introduction into an importing module via a macro created by define-unsafer.
