SSL_LIBRARY_INIT(3) Library Functions Manual SSL_LIBRARY_INIT(3)
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);
int
OpenSSL_add_ssl_algorithms(void);
int
SSLeay_add_ssl_algorithms(void);
DESCRIPTION
These functions are deprecated. It is never useful for any application program to call any of them explicitly. The library automatically calls them internally whenever needed.
SSL_library_init() registers the available ciphers and digests which are used directly or indirectly by TLS.
OpenSSL_add_ssl_algorithms() and SSLeay_add_ssl_algorithms() are synonyms for SSL_library_init() and are implemented as macros.
RETURN VALUES
SSL_library_init() always returns 1.
