SSL_library_init, OpenSSL_add_ssl_algorithms,
       SSLeay_add_ssl_algorithms - initialize SSL library by
       registering algorithms


SYNOPSIS

        #include <openssl/ssl.h>

        int SSL_library_init(void);
        #define OpenSSL_add_ssl_algorithms()    SSL_library_init()
        #define SSLeay_add_ssl_algorithms()     SSL_library_init()


DESCRIPTION

       SSL_library_init() registers the available ciphers and
       digests.

       OpenSSL_add_ssl_algorithms() and
       SSLeay_add_ssl_algorithms() are synonyms for
       SSL_library_init().


NOTES

       SSL_library_init() must be called before any other action
       takes place.


WARNING

       SSL_library_init() only registers ciphers. Another
       important initialization is the seeding of the PRNG
       (Pseudo Random Number Generator), which has to be
       performed separately.


EXAMPLES

       A typical TLS/SSL application will start with the library
       initialization, will provide readable error messages and
       will seed the PRNG.

        SSL_load_error_strings();                /* readable error messages */
        SSL_library_init();                      /* initialize library */
        actions_to_seed_PRNG();


RETURN VALUES

       SSL_library_init() always returns "1", so it is safe to
       discard the return value.
