41 * Parse a range and indicate if the range is valid.
42 * Valid ranges are in the form:
43 * <long> -> min=max=long has_min has_max
44 * -<long> -> max=long !has_min has_max
45 * <long>- -> min=long has_min !has_max
46 * <long1>-<long2> -> min=long1 max=long2 has_min has_max
48 * If the range is valid, getrange returns 1.
49 * If the range is not valid, getrange returns 0.
