+=head1 NAME
+SSL_get_peer_tmp_key, SSL_get_server_tmp_key, SSL_get_tmp_key - get information
+about temporary keys used during a handshake
+=head1 SYNOPSIS
+ #include <openssl/ssl.h>
+ long SSL_get_peer_tmp_key(SSL *ssl, EVP_PKEY **key);
+ long SSL_get_server_tmp_key(SSL *ssl, EVP_PKEY **key);
+ long SSL_get_tmp_key(SSL *ssl, EVP_PKEY **key);
+SSL_get_peer_tmp_key() returns the temporary key provided by the peer and
+used during key exchange. For example, if ECDHE is in use, then this represents
+the peer's public ECDHE key. On success a pointer to the key is stored in
+B<*key>. It is the caller's responsibility to free this key after use using
+SSL_get_server_tmp_key() is a backwards compatibility alias for
+Under that name it worked just on the client side of the connection, its
+behaviour on the server end is release-dependent.
+SSL_get_tmp_key() returns the equivalent information for the local
+end of the connection.
+All these functions return 1 on success and 0 otherwise.
+=head1 NOTES
+This function is implemented as a macro.
