80 
81     Starting from OpenSSL v1.1.0, the `sk_*` functions are prefixed with
82     `OPENSSL_`, so e.g. `sk_num` becomes `OPENSSL_sk_num`.
83 
84     To cope with that and provide downstream with an easier interface to deal
85     with, we always provide the `OPENSSL_` methods, as they are just `extern(C)`
86     anyway, and we either provide `sk_*` as `alias`es or `extern (C)`.
87 
88     The need for aliases comes from users of those binding, e.g. `safestack`.
