=========================================

Synopsis
--------

*#include <ngtcp2/ngtcp2.h>*

.. function:: int ngtcp2_conn_decode_early_transport_params(ngtcp2_conn *conn, const uint8_t *data, size_t datalen)

    
    `ngtcp2_conn_decode_early_transport_params` decodes QUIC transport
    parameters from *data* of length *datalen*, which is assumed to be
    the parameters received from the server in the previous connection,
    and sets it to *conn*.  These parameters are used to send early
    data.  QUIC requires that client application should remember
    transport parameters along with a session ticket.
    
    At least following fields should be set:
    
    - initial_max_stream_id_bidi
    - initial_max_stream_id_uni
    - initial_max_stream_data_bidi_local
    - initial_max_stream_data_bidi_remote
    - initial_max_stream_data_uni
    - initial_max_data
    - active_connection_id_limit
    - max_datagram_frame_size (if DATAGRAM extension was negotiated)
    
    This function must only be used by client.
    
    This function returns 0 if it succeeds, or one of the following
    negative error codes:
    
    :macro:`NGTCP2_ERR_NOMEM`
        Out of memory.
    :macro:`NGTCP2_ERR_MALFORMED_TRANSPORT_PARAM`
        The input is malformed.
