Re: How to get and use segment address in linux?

Aren't DS and SS flags used for 16 bits assambly only?

On 32bits you don't use them as segment  registers, and on 64bits you don't use them at all.

They are not necessary to access memory areas, thanks to the flat model.

No.
Open source is about opening the source code complying with this conditions, period. The ability to choose among several packages is just a nice side effect.
