Or, if you have a ton of stuff to copy and some of the flex_array overhead is getting in the way. I'm not opposed to it, but I think I'd want to see a user first to make sure I got the implementation right. > * (macro ?) iterate through elements (better have it ready for users > of flex_array before, than convert their code later on) I've thought about this, but I don't think there's much advantage to doing it. It obfuscates things without any real gain in simplicity. We have LIST_FOR_EACH() because containerof() and some of the typing is a little non-obvious. But, here, I think it's mostly dummy-proof: We need a 'tmp' variable here because unlike list traversal, there's no position implied in the variables. So, we're looking at (with a new macro): int tmp; FA_FOR_EACH(fa, var, tmp) foo(var); vs. int i; for (i = 0; i < fa->total_nr_elements; i++) foo(flex_array_get(fa, i)); The macro *looks* cleaner, but I don't think it really buys us much. -- Dave _______________________________________________ Containers mailing list Containers@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/containers
