okay thanks, I obtained the result desired in another way.

One more thing: somebody knows a tool that prints something each time a 
data (or piece of code) is not on the physical memory? I know that the 
Solaris command 'truss' with the '-m fltpage' do this. But I need 
something to Linux (strace doesn't do). Anyone? Please?

Thanks a lot
