It does. If a function tries to modify a formal argument which was marked const you'll get a warning.
We're talking about different things here. My point is that it is perverted and evil for a function to modify its own args (unless it's very small and simple), and a const declaration is a useful way for a maintenance programmer to be assured that nobody has done perverted and evil things to a function. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
