Can someone confirm that I'm doing this correctly? I'm trying to declare a
pointer to an array of ints. I have a index which I load dynamically, so I find
I have to do declare my pointer like this:

   int (*index)[DIM2];

This lets index act the same as if static storage was allocated with:

   int index[DIM1][DIM2];

I can now do something like index=malloc(sizeof(int)*DIM1*DIM2).

This appears to work, but seems to be highly un-intutitive! Is there no way I
can actually have [DIM1][DIM2] in the declaration, or at least [DIM1]? I just
get worried that a year from now when I change the index structure I'll screw
the pointer.

Also, I'm not too impressed by the way I have to calculate the size of the
array in the malloc(). But I don't see anyway around this.
