These functions are deprecated. It is never useful for any application program to call any of them explicitly. The library automatically calls them internally whenever needed.

() registers the available ciphers and digests which are used directly or indirectly by TLS.

() and () are synonyms for SSL_library_init() and are implemented as macros.

SSL_library_init() always returns 1.
