-  * gnutls_session_sign_algorithm_get - get signature algorithms requested by peer
-  * @session: is a #gnutls_session_t structure.
-  * @indx: is an index of the signature algorithm to return
-  * @algo: the returned certificate type will be stored there
-  *
-  * Returns the signature algorithm specified by index that was
-  * requested by the peer. If the specified index has no data
-  * available this function returns
-  * %GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE.  If the negotiated TLS
-  * version does not support signature algorithms then
-  * %GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned even for
-  * the first index.
-  *
-  * This function is usefull in the certificate callback functions
-  * to assist in selecting the correct certificate.
-  *
-  * Returns: On success, %GNUTLS_E_SUCCESS (0) is returned, otherwise
-  *   an error code is returned.
