| 18 | =head1 DESCRIPTION
|
|---|
| 19 |
|
|---|
| 20 | SSL_CTX_set_tmp_ecdh() sets ECDH parameters to be used to be B<ecdh>.
|
|---|
| 21 | The key is inherited by all B<ssl> objects created from B<ctx>.
|
|---|
| 22 | This macro is deprecated in favor of L<SSL_CTX_set1_groups(3)>.
|
|---|
| 23 |
|
|---|
| 24 | SSL_set_tmp_ecdh() sets the parameters only for B<ssl>.
|
|---|
| 25 | This macro is deprecated in favor of L<SSL_set1_groups(3)>.
|
|---|
| 26 |
|
|---|
| 27 | SSL_CTX_set_ecdh_auto() and SSL_set_ecdh_auto() are deprecated and
|
|---|
| 28 | have no effect.
|

| 30 | =head1 RETURN VALUES
|
|---|
| 31 |
|
|---|
| 32 | SSL_CTX_set_tmp_ecdh() and SSL_set_tmp_ecdh() return 1 on success and 0
|
|---|
| 33 | on failure.
