int
SSL_CTX_set_ssl_version
(SSL_CTX
*ctx, const
SSL_METHOD *method);
int

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
called.
SSL_set_ssl_method
() sets a new TLS/SSL
method for a particular
SSL object
s. It may be reset when
SSL_clear(3) is
called.
SSL_CTX_get_ssl_method
() and
SSL_get_ssl_method
() return a function
pointer to the TLS/SSL method set in ctx and
ssl, respectively.
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 forSSL_CTX_set_ssl_version
() and
SSL_set_ssl_method
():
- 0
- The new choice failed. Check the error stack to find out the reason.
- 1
