   <dd>The library only shallow copies objects into the buffer, it will not call the copy constructor. For many C++ objects this works fine, but if you require a deep copy you will have to look into libraries that supports something like C++ templates. And to be honest, you shouldn't be doing deep copies on a microcontroller or you could get random freezes from memory fragmentation.</dd>
