I've always thought of "!!" as the "canonicalize boolean" operator... Vaguely ugly, but I think it's actually _more clear_ than != 0 in contexts where the value is already "boolean" in the C zero or not-zero sense, but you want a "proper" boolean (0 or 1) for some reason. -miles -- Somebody has to do something, and it's just incredibly pathetic that it has to be us. -- Jerry Garcia - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
