Right syntax to make contents of an array volatile?

Question

I vaguely remember that the order of the volatile keyword has influence on wether you want the pointer to the array to be volatile or the contents itself. If I want the content to be volatile, do I need to write:

volatile short Array[];

or

short volatile Array[3];

Either will do. It is the difference between

short volatile * ptr; /* pointer to volatile short */

and

short * volatile ptr; /* volatile pointer to short */

that matters.

const behaves the same way.

Both of them will work fine. Order of specifiers doesn't matter.

As you see in user694733 answer, the order may matter. – Maestro Sep 04 '13 at 13:49
