ngtcp2_conn_update_pkt_tx_time
==============================

Synopsis
--------

*#include <ngtcp2/ngtcp2.h>*

.. function:: void ngtcp2_conn_update_pkt_tx_time(ngtcp2_conn *conn, ngtcp2_tstamp ts)

    
    `ngtcp2_conn_update_pkt_tx_time` sets the time instant of the next
    packet transmission to pace packets.  This function must be called
    after (multiple invocation of) `ngtcp2_conn_writev_stream`.  If
    packet aggregation (e.g., packet batching, GSO) is used, call this
    function after all aggregated datagrams are sent, which indicates
    multiple invocation of `ngtcp2_conn_writev_stream`.
