No casting to a constant memory value

[anxious7]

what should i do in order to avoid casting in this situation ?

(unknown data type) *ptr = 0x00102f3c;

Unless you're writing for DOS, or an embedded platform, why would you want to?

[anxious7]

it's for an embedded system

So what's the problem with using a cast?

You could hide it inside a macro, say
[tt]#define MK_PTR(x) ((void*)(x))[/tt]

Or maybe a short, possibly inline, function, say

void *mk_ptr ( unsigned long addr ) {
  return (void*)addr;
}

[anxious7]

is casting inevitable ?

Maybe not, but before I think about some horribly contrived answer, why are you so against the idea of having just one cast to do one known thing?
