    following state change event from multi_role as an example of this:

       ICall_freeMsg(pMsg->pData);
       break;
    @endcode

    If the message is not successfully queued to the application, TRUE is returned
    so that the GAPRole can deallocate the message. If the heap has enough room,
    the message must always be successfully enqueued.
