SSL_library_init, OpenSSL_add_ssl_algorithms
- 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.
=head1 NOTES
SSL_library_init() must be called before any other action takes place.
SSL_library_init() is not reentrant.
=head1 WARNINGS
SSL_library_init() adds ciphers and digests used directly and indirectly by
SSL/TLS.
=head1 RETURN VALUES

value.
