Application connected to core instance

In <outputfolder>/bin start the instance 3001 with following parameter: sdv_control STARTUP --instance3001.

When the instance is running the application system_demo_example can be started as external application, meaning not loading the components but to connect to the running instance.

In <outputfolder>/examples/bin start the application with following parameter: sys_demo_example -f../../bin --instance3001 --connect.

the following shows the system:

This code shows the basic code to connect to a running instance. It tries to connect to the example with the instance 3001. If successful it will get the interface of the :Complex Service. It would also be possible to get the interfaces of the :Basic Service.

/**

    const char* envVariable = std::getenv("SDV_FRAMEWORK_RUNTIME");
    if (envVariable)

        return true;
    }
    return false;

    uint32_t uiInstance = 3001;
    sdv::app::CAppControl appcontrol;
    if (!IsSDVFrameworkEnvironmentSet())
    {
        // if SDV_FRAMEWORK_RUNTIME environment variable is not set we need to set the Framework Runtime directory
        appcontrol.SetFrameworkRuntimeDirectory("../../bin");
    }

    appcontrol.AddModuleSearchDir("../../bin");

    std::stringstream sstreamAppConfig;
    sstreamAppConfig << "[Application]" << std::endl;
    sstreamAppConfig << "Mode=\"External\"" << std::endl;
    sstreamAppConfig << "Instance=" << uiInstance << std::endl;
    sstreamAppConfig << "Retries=" << 10 << std::endl;    
    sstreamAppConfig << "[Console]" << std::endl;
    sstreamAppConfig << "Report=\"Verbose\"" << std::endl;

    // Start the framework as external application, which wants to connect to instance 3001
    if (!appcontrol.Startup(sstreamAppConfig.str()))
    {
        std::cout << "appcontrol.Startup() failed." << std::endl;
        return false;
    }

    auto pCounterSteeringSvc = sdv::core::GetObject("Counter Steering Example Service").GetInterface<ICounterSteeringService>();
    if (!pCounterSteeringSvc)
    {
        std::cout << "\nERROR: Could not get 'ICounterSteeringService', connection to " << std::to_string (uiInstance) << "probably failed.\n" << std::endl;
        return false;
    }

    std::cout << "\nSUCCESS: Got 'ICounterSteeringService', could connect to instance." << std::to_string (uiInstance) << "\n" << std::endl;

    return true;
}

Just start the sdv::app::CAppControl with a configuration instead of an empty string. Set Mode = External and Instance to the instance number the application has to connect to.
