.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fISSL_CTX_set_ssl_version()\fR sets a new default \s-1TLS/SSL\s0 \fBmethod\fR for \s-1SSL\s0 objects
newly created from this \fBctx\fR. \s-1SSL\s0 objects already created with
SSL_new(3) are not affected, except when
SSL_clear(3) is being called.
.PP
\&\fISSL_set_ssl_method()\fR sets a new \s-1TLS/SSL\s0 \fBmethod\fR for a particular \fBssl\fR
object. It may be reset, when \fISSL_clear()\fR is called.
.PP
\&\fISSL_get_ssl_method()\fR returns a function pointer to the \s-1TLS/SSL\s0 method
set in \fBssl\fR.
.SH "NOTES"
.IX Header "NOTES"
The available \fBmethod\fR choices are described in
SSL_CTX_new(3).
.PP
When SSL_clear(3) is called and no session is connected to
an \s-1SSL\s0 object, the method of the \s-1SSL\s0 object is reset to the method currently
set in the corresponding \s-1SSL_CTX\s0 object.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
The following return values can occur for \fISSL_CTX_set_ssl_version()\fR
and \fISSL_set_ssl_method()\fR:
.Ip "0" 4
The new choice failed, check the error stack to find out the reason.
.Ip "1" 4
.IX Item "1"
The operation succeeded.
