SSL_CTX_set_ssl_version, SSL_set_ssl_method, SSL_get_ssl_method - choose a new TLS/SSL method
#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);
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 are not affected, except when SSL_clear 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.
The available method choices are described in SSL_CTX_new.
When SSL_clear 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.
The following return values can occur for SSL_CTX_set_ssl_version() and SSL_set_ssl_method():
The new choice failed, check the error stack to find out the reason.
The operation succeeded.
