sk_dup

Starting from OpenSSL v1.1.0, the sk_* functions are prefixed with OPENSSL_, so e.g. sk_num becomes OPENSSL_sk_num.

To cope with that and provide downstream with an easier interface to deal with, we always provide the OPENSSL_ methods, as they are just extern(C) anyway, and we either provide sk_* as aliases or extern (C).

The need for aliases comes from users of those binding, e.g. safestack.

  1. alias sk_dup = OPENSSL_sk_dup
    version(DeimosOpenSSLv1_1)
    extern (C) nothrow
    alias sk_dup = OPENSSL_sk_dup
  2. _STACK* sk_dup(_STACK* st)
