本文介绍了嵌入式系统中线程的管理方法，包括如何强行结束并挂起线程，以及重新启动线程的过程。此外还涉及了网络相关API的使用，如获取本地时间、TCP/UDP套接字操作等。

一个线程，强行结束另外一个线程，并将其挂起：

static void SuspendTask(TX_THREAD *thread)
{
    UINT status = 0;
    UINT state;

    status = tx_thread_terminate(thread);
    if(status != TX_SUCCESS)
        return ;
    do
    {
        tx_thread_sleep(1);
        status = tx_thread_info_get(thread, NULL, &state, NULL, NULL, NULL, NULL, NULL, NULL);
        if (status != TX_SUCCESS)
        {
            xp_log("can not get clean thread status (0x%02x)\r\n", status);
            break;
        }
    } while (!(state & (TX_COMPLETED | TX_TERMINATED)));
    tx_thread_reset(thread);
}

启动

static void StartRawTask(void)
{
    UINT status = 0;
    UINT state;

    status = tx_thread_info_get(&rawThread, NULL, &state, NULL, NULL, NULL, NULL, NULL, NULL);
    if(status == TX_SUCCESS)
    {
        if(state == TX_SUSPENDED)
            tx_thread_resume(&rawThread);
    }
    else
        tx_thread_create(&rawThread, (CHAR *) "raw thread", RawThreadCallback, (ULONG)(&MaterialBoxTempT3), &raw_stack, COMMON_THREAD_STACK, 6, 6, 0, TX_AUTO_START);
}

    /* Get local time as set by SNTP client */
    status = nx_sntp_client_get_local_time(&g_sntp_client, &seconds, &milliseconds, NX_NULL);
    if (status != NX_SUCCESS)
        return 0;

    /* Convert to Unix epoch */
    seconds -= UNIX_TO_NTP_EPOCH_SECS;

    return seconds;
}
