How to identity processor architecture

[prabhu]

Hi Enrico,

I am not sure.

No, because 32bit code will tell the datatype size and i think pointer 
variable depends on architecture.
So 64 bit processor needs 64 address line to point the data location. So 
pointer variable needs to be 8 byte.

please correct me if i am worng.

Thanks,
Prabhu
