<div class="markdown_content"><p>Is there a way to do function callbacks in V3.<br/> What I wan't is to call a function when data arrives on TCP and are parsed and ready.</p> <p>It's sort of an event handler where I want to "subscribe" for different types of data and when they arrive I would like to call the provided function.</p> <p>The "subscription" could be initiated with something like this...<br/> MyFancyFB.Subscribe(sFilter:='I Listen For', pFunc := ADR(MyReceivingFunction));</p> <p>I'v looked at CAA_Callback but that seems to be for just specific system events, but I might be wrong.</p> <p>Anyone have suggestions...<br/> Is it at all possible?</p></div>
