+
+#include <openssl/ssl.h>
+
+long SSL_CTX_set_tmp_ecdh(SSL_CTX *ctx, const EC_KEY *ecdh);
+long SSL_set_tmp_ecdh(SSL *ssl, const EC_KEY *ecdh);

+=head1 DESCRIPTION
+
+SSL_CTX_set_tmp_ecdh() sets ECDH parameters to be used to be B<ecdh>.
+The key is inherited by all B<ssl> objects created from B<ctx>.
+
+SSL_set_tmp_ecdh() sets the parameters only for B<ssl>.
+
+SSL_CTX_set_ecdh_auto() and SSL_set_ecdh_auto() are deprecated and
+have no effect.
