@defmodule[net/osx-ssl]{The @racketmodname[net/osx-ssl] module
offers a fraction of the functionality of @racketmodname[openssl] and
works only on Mac OS, but it has the advantage that it works before
OpenSSL libraries are installed.}

Like @racket[ssl-connect], but without support for client contexts.}


@defproc[(osx-ssl-abandon-port [in osx-ssl-output-port?]) void?]{

Analogous to @racket[ssl-abandon-port].}


@defproc[(osx-ssl-output-port? [v any/c]) boolean?]{

Returns @racket[#t] of @racket[v] is an SSL output port produced by
@racket[osx-ssl-connect].}


@defproc[(osx-old-openssl?) boolean?]{

Returns @racket[#t] if the OpenSSL library currently accessed by
@racketmodname[openssl] is too old, in which case
@racket[osx-ssl-connect] should be preferred.}
