Call Library Function

[thenoob94]

I have the following c function:

extern "C"{

int getInterfaces( uint32_t numInterface, void* g_hSystem);
    
}

int getInterfaces( uint32_t numInterface, void* g_hSystem)
{
    //Get Interface
    bool bChanged = false;

    SV_RETURN ret = SVSystemUpdateInterfaceList(g_hSystem, &bChanged, 1000);
    if (SV_ERROR_SUCCESS != ret)
    {
        printf("%s SVSystemUpdateInterfaceList failed!:%d\n", __FUNCTION__, ret);
        return -1;
    }

    ret = SVSystemGetNumInterfaces(g_hSystem, &numInterface);
    if (SV_ERROR_SUCCESS != ret)
    {
        printf("%s SVSystemGetNumInterfaces failed!:%d\n", __FUNCTION__, ret);
        return -1;
    }

    if (0 == numInterface)
    {
        printf("%s No Interface Available!\n", __FUNCTION__);
        return -1;
    }
}

 

How would I create "void* g_hSystem" in Labview?

You need the .h file which defines g_hSystem.
