I tried to do this:

int* pointer = whatever;
if (pointer & 0xFFF == 0) dosomething();

Didn't compile.

Tried this:

if (((int)pointer) & 0xFFF == 0) dosomething();

And it follows (dereferences) the pointer, instead of using the address of the pointer itself.

I'm doing the craziest shit, ain't I?

I'm no C pro (or is this C++ ?), but I'm not sure exactly what you're trying to do.

But beware precedence levels. So, while it doesn't fix your problem, be careful of this:

You may also wish to use stdint.h 's intptr_t and uintptr_t .

Perfect, thank you! This worked:

if (((intptr_t)pointer & 0xFFF) == 0) break;
