NAME

       SSL_CTX_set_ssl_version, SSL_set_ssl_method, SSL_get_ssl_method -
       choose a new TLS/SSL method

SYNOPSIS

        #include <openssl/ssl.h>

        int SSL_CTX_set_ssl_version(SSL_CTX *ctx, const SSL_METHOD *method);
        int SSL_set_ssl_method(SSL *s, const SSL_METHOD *method);
        const SSL_METHOD *SSL_get_ssl_method(SSL *ssl);

DESCRIPTION

       SSL_CTX_set_ssl_version() sets a new default TLS/SSL method for SSL
       objects newly created from this ctx. SSL objects already created with
       SSL_new(3) are not affected, except when SSL_clear(3) is being called.

       SSL_set_ssl_method() sets a new TLS/SSL method for a particular ssl
       object. It may be reset, when SSL_clear() is called.

       SSL_get_ssl_method() returns a function pointer to the TLS/SSL method
       set in ssl.

NOTES

       The available method choices are described in SSL_CTX_new(3).

       When SSL_clear(3) is called and no session is connected to an SSL
       object, the method of the SSL object is reset to the method currently
       set in the corresponding SSL_CTX object.

RETURN VALUES

       The following return values can occur for SSL_CTX_set_ssl_version() and
       SSL_set_ssl_method():

       0   The new choice failed, check the error stack to find out the rea-
           son.

       1   The operation succeeded.
