RTOS: OPC UA - ANSI C Stack

Tool/software: TI-RTOS

Hello,

Last time I started a thread for OPC UA. Now I am planning to restart the project. 

As I look around I found to ways to go ahead. One is the purchase license from an SDK Vendor such as Matrikon or implement my own solution. I am waiting for reply from them, because their licensing model is not clear for me.

Right now I like the 2nd option. Do you have any experience with OPC UA ANSI C source? 

What do you think about the OPC UA ANSI C - TI RTOS integration? I don't see any issue that makes the integration impossible. Do you?

Thank you for your reply

    I'm not familiar with OPC UA. Maybe someone else on this forum has some experience and can comment. I think you should review the TI-RTOS docs and examples and come back with more specific concerns or questions.

    Thanks,

    Hello, well I have a specific question.

    I am trying to port the following code section to TI-RTOS:

    OpcUa_StatusCode OpcUa_P_RawSocket_CreateSocketPair(  OpcUa_RawSocket* pRawSocketRead, OpcUa_RawSocket* pRawSocketWrite)
{

      int filedes[2];
      int retval = socketpair(AF_UNIX, SOCK_STREAM, 0, filedes);
    
      if(retval<0)
      {
        *pRawSocketRead  = (OpcUa_RawSocket)OPCUA_P_SOCKET_INVALID;
        *pRawSocketWrite = (OpcUa_RawSocket)OPCUA_P_SOCKET_INVALID;
        return OpcUa_Bad;
      }
    
      *pRawSocketRead  = (OpcUa_RawSocket)filedes[1];
      *pRawSocketWrite = (OpcUa_RawSocket)filedes[0];
      
       return OpcUa_Good;
}

    And my problem is how can I implement socketpair() in RTOS? Any idea?

    Found an example of how to implement socketpair() using socket primitives, albeit in Python rather than C - https://gist.github.com/geertj/4325783

    Does that help?
