With some inline assembly. On x86, you could try something like:
int cs_val;
asm("mov %%cs, %0": "=r"(cs_val));
I haven't tested this, so I have no idea if I have the inline assembly
syntax correct.
BTW, this kind of stuff is not useful from within a program. A running
program will modify its own registers. Why do you think this can be
useful for you?
