Code
===========

    // create socket
    mSocketRef = CFSocketCreate( kCFAllocatorDefault, PF_INET, SOCK_STREAM, IPPROTO_TCP,  kCallbackTypes,
                                (CFSocketCallBack)VideoSocket::_SocketCallBack, context );

  // Create socket runloop source
    mRunLoopSource = CFSocketCreateRunLoopSource(kCFAllocatorDefault, mSocketRef, 0);
    if(mRunLoopSource == NULL)
    {
        fprintf(stderr, "DCSocket::Failed to create runloop source" );
        return false;
    }
   
    // add socket source to runloop
    CFRunLoopAddSource(CFRunLoopGetCurrent(), mRunLoopSource, kCFRunLoopDefaultMode);
    CFRelease(mRunLoopSource);
