7.8 Handling alerts

During a TLS connection alert messages may be exchanged by the two peers. Those messages may be fatal, meaning the connection must be terminated afterwards, or warning when something needs to be reported to the peer, but without interrupting the session. The error codes GNUTLS_E_WARNING_ALERT_RECEIVED or GNUTLS_E_FATAL_ALERT_RECEIVED signal those alerts when received, and may be returned by all GnuTLS functions that receive data from the peer, being gnutls_handshake and gnutls_record_recv. Alerts messages may be sent to the peer using gnutls_alert_send.
