Introduce strtonum(), which works like string_to_number(), but passes
back the 'end' pointer. It is useful where you want to do boundary checking yet work with strings that are not entirely slurped by strtoul(), e.g.: s = "1/2"; /* one half */ if (!strtonum(s, &end, &value, 0, 5)) error("Zero-length string, or value out of bounds"); if (*end != '/') error("Malformed string"); info->param1 = value; if (!strtonum(end + 1, &end, &value, 2, 4)) error(".."); if (*end != '\0') error("Malformed string"); info->param2 = value; Signed-off-by: Jan Engelhardt <jengelh@computergmbh.de>
