CC3200 socket 设置为非阻塞

TI：

我是按照 TCP socket demo

    iSockID = sl_Socket(SL_AF_INET,SL_SOCK_STREAM, 0);
    if( iSockID < 0 )
    {
        // error
        ASSERT_ON_ERROR(SOCKET_CREATE_ERROR);
    }

    iAddrSize = sizeof(SlSockAddrIn_t);

    // binding the TCP socket to the TCP server address
    iStatus = sl_Bind(iSockID, (SlSockAddr_t *)&sLocalAddr, iAddrSize);
    if( iStatus < 0 )
    {
        // error
        sl_Close(iSockID);
        ASSERT_ON_ERROR(BIND_ERROR);
    }

    // putting the socket for listening to the incoming TCP connection
    iStatus = sl_Listen(iSockID, 0);
    if( iStatus < 0 )
    {
        sl_Close(iSockID);
        ASSERT_ON_ERROR(LISTEN_ERROR);
    }

    // setting socket option to make the socket as non blocking
    iStatus = sl_SetSockOpt(iSockID, SL_SOL_SOCKET, SL_SO_NONBLOCKING,
                            &lNonBlocking, sizeof(lNonBlocking));
    if( iStatus < 0 )
    {
        sl_Close(iSockID);
        ASSERT_ON_ERROR(SOCKET_OPT_ERROR);
    }
    iNewSockID = SL_EAGAIN;

    // waiting for an incoming TCP connection
    while( iNewSockID < 0 )
    {
        // accepts a connection form a TCP client, if there is any
        // otherwise returns SL_EAGAIN
        iNewSockID = sl_Accept(iSockID, ( struct SlSockAddr_t *)&sAddr,
                                (SlSocklen_t*)&iAddrSize);
        if( iNewSockID == SL_EAGAIN )
        {
           MAP_UtilsDelay(10000);
        }
        else if( iNewSockID < 0 )
        {
            // error
            sl_Close(iNewSockID);
            sl_Close(iSockID);
            ASSERT_ON_ERROR(ACCEPT_ERROR);
        }
    }

    // waits for 1000 packets from the connected TCP client
    while (lLoopCount < g_ulPacketCount)
    {
        iStatus = sl_Recv(iNewSockID, g_cBsdBuf, iTestBufLen, 0);
        if( iStatus <= 0 )
        {
          // error
          sl_Close(iNewSockID);
          sl_Close(iSockID);
          ASSERT_ON_ERROR(RECV_ERROR);
        }

        lLoopCount++;
    }

    Report("Recieved %u packets successfully\n\r",g_ulPacketCount);

    // close the connected socket after receiving from connected TCP client
    iStatus = sl_Close(iNewSockID);

这个 sl_SetSockOpt(); 试过任何位置， 从socket() 后面到 Recv() 前面都试过， 也试过多次设置， 非阻塞都是无效。

请问， 作为 TCP Server 应该怎么设置这个非阻塞呢？

TCP Server设置非阻塞时，要在socket创建成功后设置，并且参数要正确，在你的程序中调用SetSockOpt输入参数第一项要用iNewSockID，而不是iSockID。
