There's strbuf_getwholeline_fd, but it's horrifically inefficient (one syscall per character). But the other option is to implement your own buffering, and we're generally better off letting stdio do that for us (the exception here is that stdio does not have a good NUL-safe "read until X" function). -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
