interacts with C APIs in general.
Since using the FFI entails many safety concerns that Scheme
programmers can normally ignore, merely importing
@schememodname[scheme/foreign] with @scheme[(require scheme/foreign)]
does not import all of the FFI functionality. Only safe functionality
is immediately imported. For example, @scheme[ptr-equal?] can never
cause memory corruption or an invalid memory access, so it is
immediately available on import.
Use @scheme[(@#,indexed-scheme[unsafe!])] at the top-level of a
module that imports @schememodname[scheme/foreign] to make unsafe
features accessible. (For additional safety, the @scheme[unsafe!] is
itself protected; see @secref[#:doc '(lib
"scribblings/reference/reference.scrbl") "modprotect"].) Using this
macro should be considered as a declaration that your code is itself
unsafe, therefore can lead to serious problems in case of bugs: it is
your responsibility to provide a safe interface. Bindings that become
available only via @scheme[unsafe!] are documented in this manual in
sections with titles starting ``Unsafe.''
programmers can normally ignore, the library name includes
@schemeidfont{unsafe}. Importing the library macro should be
considered as a declaration that your code is itself unsafe, therefore
can lead to serious problems in case of bugs: it is your
responsibility to provide a safe interface. If your library provides
an unsafe interface, then it should have @schemeidfont{unsafe} in its
name, too.
For examples of common FFI usage patterns, see the defined interfaces
in the @filepath{ffi} collection.

The @schememodname[scheme/load] language supports traditional Scheme
The @schememodname[racket/load] language supports traditional Scheme
evaluation, where each top-level form in the module body is separately
passed to @scheme[eval] in the same way as for @scheme[load].
The namespace for evaluation shares the @tech{module registry} with
the @schememodname[scheme/load] module instance, but it has a separate
the @schememodname[racket/load] module instance, but it has a separate
top-level environment, and it is initialized with the bindings of
@schememodname[scheme]. A single namespace is created for each
instance of the @schememodname[scheme/load] module (i.e., multiple
modules using the @schememodname[scheme/load] language share a
namespace). The @scheme[scheme/load] library exports only
instance of the @schememodname[racket/load] module (i.e., multiple
modules using the @schememodname[racket/load] language share a
namespace). The @scheme[racket/load] library exports only
@schemeidfont{#%module-begin} and @schemeidfont{#%top-interaction}
forms that effectively swap in the evaluation namespace and call
@scheme[eval].
For example, the body of a module using @scheme[scheme/load] can
For example, the body of a module using @scheme[racket/load] can
include @scheme[module] forms, so that running the following module
prints @schemeresultfont{5}:
@schememod[
scheme/load
racket/load
(module m scheme/base
(module m racket/base
(provide x)
(define x 5))
(module n scheme/base
(module n racket/base
(require 'm)
(display x))
(require 'n)
]
Definitions in a module using @scheme[scheme/load] are evaluated in
Definitions in a module using @scheme[racket/load] are evaluated in
the current namespace, which means that @scheme[load] and
@scheme[eval] can see the definitions. For example, running the
following module prints @schemeresultfont{6}:
@schememod[
scheme/load
racket/load
(define x 6)
(display (eval 'x))
]
Since all forms within a @schememodname[scheme/load] module are
Since all forms within a @schememodname[racket/load] module are
evaluated in the top level, bindings cannot be exported from the
module using @scheme[provide]. Similarly, since evaluation of the
module-body forms is inherently dynamic, compilation of the module
provides essentially no benefit. For these reasons, use
@schememodname[scheme/load] for interactive exploration of top-level
@schememodname[racket/load] for interactive exploration of top-level
forms only, and not for constructing larger programs.
