     NAME
          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.
