<body>I don't recall suggesting "void" pointers. I suggested reference-counted (and thus, typed) pointers.<br><br><div class="gmail_quote">Le 19 août 2018 11:16:19 GMT+03:00, Thomas Guillem <thomas@gllm.fr> a écrit :<blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
<div>I agree about keeping fmt.id for TS ES and using an unique ID for libvlc or the new input manager.<br></div>

<div>Using a void* can be racy when deleting and creating an ES (the es can use the same pointer).<br></div>
<div><br></div>
<div>An integer overflow is very unlikely to happen when creating an ES (and we can still check the overflw and fail if it happens). </div>

<div>Do you still prefer using void* ?</div>

<div> But as François pointed out, no matter how large the integer, you can always overflow after long enough.<br></div>
<div> <br></div>
<div> I just don't see the point in using handles or IDs when you can use pointers. Pointers are generally the easiest identifier in C.<br></div>

<div> You can't track usable ids unless you allocate UINTxx_MAX bits to<br></div>
