uggh.. do you not know? did you not put it there? usually wanting to do something like this is due to bad design and a good think about it will sort it out for you... there is no easy way and I'm loathe to suggest a way.. you parse /proc/self/maps and you figure out from that if the address of the string is in a r-x or rw- area.. I persume you mean from userspace.. if you're in the kernel get back to me, it'll be probably not as hard or maybe twice as hard.. again you probably only think you want to do this and you probably don't need to ..
