=head1 NAME

SSL_library_init, OpenSSL_add_ssl_algorithms,
- initialize SSL library by registering algorithms

=head1 SYNOPSIS

 #include <openssl/ssl.h>

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

=head1 DESCRIPTION

SSL_library_init() registers the available SSL/TLS ciphers and digests.

OpenSSL_add_ssl_algorithms() is a synonym for SSL_library_init().

=head1 NOTES

SSL_library_init() must be called before any other action takes place.
SSL_library_init() is not reentrant. 

=head1 WARNING

SSL_library_init() adds ciphers and digests used directly and indirectly by
SSL/TLS.

=head1 EXAMPLES

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

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

=head1 RETURN VALUES

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