'int' is no good, because in the 64 bit ABI, an 'int' is still 32 bit,
but a pointer (like 'id') is 64 bit. I suggest using NSUInteger because
it is always the same size as a pointer (32 in 32bit and 64 in 64bit).
Likewise, %i should be %lu.
Do I understand correctly that this API takes an ASCII string (of a
base-10 number) that represents a pointer address?!? That's strange,
no? This is likely to wreak havoc with Obj-C garbage collection....
