.SH SYNOPSIS
.IX Header "SYNOPSIS"
.Vb 1
\& #include <openssl/ssl.h>
\&
\& int SSL_CTX_set_ssl_version(SSL_CTX *ctx, const SSL_METHOD *method);

.SH DESCRIPTION
.IX Header "DESCRIPTION"
\&\fBSSL_CTX_set_ssl_version()\fR sets a new default TLS/SSL \fBmethod\fR for SSL objects
newly created from this \fBctx\fR. SSL objects already created with
\&\fBSSL_new\fR\|(3) are not affected, except when
\&\fBSSL_clear\fR\|(3) is being called.
.PP
\&\fBSSL_set_ssl_method()\fR sets a new TLS/SSL \fBmethod\fR for a particular \fBssl\fR
object. It may be reset, when \fBSSL_clear()\fR is called.
.PP
\&\fBSSL_get_ssl_method()\fR returns a function pointer to the TLS/SSL method
set in \fBssl\fR.
.SH NOTES
.IX Header "NOTES"
The available \fBmethod\fR choices are described in
\&\fBSSL_CTX_new\fR\|(3).
.PP
When \fBSSL_clear\fR\|(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.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
The following return values can occur for \fBSSL_CTX_set_ssl_version()\fR
and \fBSSL_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.
