I think you're probably getting into premature optimization here. Using strbuf_vaddf should be within the same order of magnitude of instructions (and I think we should almost never hit this code path anyway, because we'll be reading into a static strbuf generally which will come pre-sized to hold a date). -Peff -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
