gnutls_alert_send - API function
int gnutls_alert_send(gnutls_session_t session, gnutls_alert_level_t level, gnutls_alert_description_t desc);
This function will send an alert to the peer in order to inform him of something important (eg. his Certificate could not be verified). If the alert level is Fatal then the peer is expected to close the connection, otherwise he may ignore the alert and continue.
The error code of the underlying record send function will be returned, so you may also receive GNUTLS_E_INTERRUPTED or GNUTLS_E_AGAIN as well.
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise an error code is returned.
