<p dir="auto">Yeah, I get this. And I agree with that comment in regards to application code. Though it needs to take special care as "not a constant" may also overflow (or at least stress) the amount of RAM that you have.</p>
<p dir="auto">And IMO, for library code the pros and cons listed are still valid.</p>
<p dir="auto">So I wonder if we should discuss other possibilities as well, like supporting only a defined upper path length of e.g. 4095 bytes (excl. 0-byte). This would allow either stack allocation or careful pre-allocation during init phase.</p>
<p dir="auto">An alternative would be a macro that does stack allocation if path length < 4096, else fall back to heap allocation. A MALLOC and a FREE macro could be used to hide the details.</p>
<p dir="auto">Maybe you have other ideas ? And 4096 is just an arbitrary values - it could as well be 1024 or 512, as we likely never see such path length in reality.</p>
