[ this latest and greatest hotmail refuses to put ">" on earlier text and seems to resent the idea I would decline to send html. LOL ] There is no requirement that the address space cardinality as reflected in the size of a pointer be related to relevant registers or bus size or anything having to do with your application needs. Sure, normally registers are sized to manipulate addresses and usually this would be a reasonable guess on register size but may not be related to various bus sizes. More important things, like cache size, would be nice to learn about at runtime. As a person who likes to write lower level code and gets annoyed manipulating char's knowing that registers and buses are wider, I have a lot of sympathy, but you first need to size your structures for your needs. What did the OP mean by "best?"

Just curious why it's not there already.
