SSL_CTX_set_ssl_version(3)   OpenSSL   SSL_CTX_set_ssl_version(3)

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 reason.

     1   The operation succeeded.
