+SSL_set_current_cert() also supports the option B<SSL_CERT_SET_SERVER>.
+If B<ssl> is a server and has sent a certificate to a connected client
+this option sets that certificate to the current certificate and returns 1.
+If the negotiated ciphersuite is anonymous (and thus no certificate will
+be sent) 2 is returned and the current certificate is unchanged. If B<ssl>
+is not a server or a certificate has not been sent 0 is returned and
+the current certificate is unchanged.
