RTOS/EK-TM4C1294XL: How to call Task_create with two different ports, i required to simultaneously send/receive from 3 ports with multi task.

Hi,

 I assume you are talking about multiple "Ethernet" ports based on the other post you are referencing. Is this correct? Did you have a chance to check out the tcpEcho example from TI-RTOS?

  Below is the snippet of code in that example that uses the task_create() to create a socket connection. If you have multiple ports I guess you can replicate this task_create() per your application. 

  In tcpEchoHooks.c 

void netOpenHook()
{
    Task_Handle taskHandle;
    Task_Params taskParams;
    Error_Block eb;

    /* Make sure Error_Block is initialized */
    Error_init(&eb);

    /*
     *  Create the Task that farms out incoming TCP connections.
     *  arg0 will be the port that this task listens to.
     */
    Task_Params_init(&taskParams);
    taskParams.stackSize = TCPHANDLERSTACK;
    taskParams.priority = 1;
    taskParams.arg0 = TCPPORT; // TCPPORT is specified in the #define
    taskHandle = Task_create((Task_FuncPtr)tcpHandler, &taskParams, &eb);
    if (taskHandle == NULL) {
        System_printf("netOpenHook: Failed to create tcpHandler Task\n");
    }

In tcpEcho.c

Void tcpHandler(UArg arg0, UArg arg1)
{
    int                status;
    int                clientfd;
    int                server;
    struct sockaddr_in localAddr;
    struct sockaddr_in clientAddr;
    int                optval;
    int                optlen = sizeof(optval);
    socklen_t          addrlen = sizeof(clientAddr);
    Task_Handle        taskHandle;
    Task_Params        taskParams;
    Error_Block        eb;

    server = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
    if (server == -1) {
        System_printf("Error: socket not created.\n");
        goto shutdown;
    }


    memset(&localAddr, 0, sizeof(localAddr));
    localAddr.sin_family = AF_INET;
    localAddr.sin_addr.s_addr = htonl(INADDR_ANY);
    localAddr.sin_port = htons(arg0);
