Synopsis
--------

*#include <ngtcp2/ngtcp2_crypto_gnutls.h>*

.. function:: int ngtcp2_crypto_gnutls_configure_server_session(gnutls_session_t session)

    
    `ngtcp2_crypto_gnutls_configure_server_session` configures
    *session* for server side QUIC connection.  It performs the
    following modifications:
    
    - Set gnutls_handshake_set_secret_function.
    - Set gnutls_handshake_set_read_function.
    - Set gnutls_alert_set_read_function.
    - Register a TLS extension handler for QUIC Transport Parameters.
    
    Application must set a pointer to :type:`ngtcp2_crypto_conn_ref` to
    gnutls_session_t object by calling gnutls_session_set_ptr, and
    :type:`ngtcp2_crypto_conn_ref` object must have
    :member:`ngtcp2_crypto_conn_ref.get_conn` field assigned to get
    :type:`ngtcp2_conn`.
    
    It returns 0 if it succeeds, or -1.
