- initialize SSL library by registering algorithms

=head1 SYNOPSIS

 #include <openssl/ssl.h>

 int SSL_library_init(void);

 int OpenSSL_add_ssl_algorithms(void);

=head1 DESCRIPTION

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

OpenSSL_add_ssl_algorithms() is a synonym for SSL_library_init() and is
implemented as a macro.

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

=head1 WARNING

SSL/TLS.

value.
