.. function:: int nghttp3_conn_set_client_stream_priority(nghttp3_conn *conn, int64_t stream_id, const uint8_t *data, size_t datalen)

    
    `nghttp3_conn_set_client_stream_priority` updates priority of a
    stream denoted by *stream_id* with the value pointed by *data* of
    length *datalen*, which should be a serialized :rfc:`9218` priority
    field value.  *stream_id* must identify client initiated
    bidirectional stream.
    
    This function must not be called if *conn* is initialized as
    server.
    
    This function returns 0 if it succeeds, or one of the following
    negative error codes:
    
    :macro:`NGHTTP3_ERR_INVALID_ARGUMENT`

    :macro:`NGHTTP3_ERR_STREAM_NOT_FOUND`
        Stream not found.
    :macro:`NGHTTP3_ERR_NOMEM`
