Changing fundamental syscalls and structures would defeat this and make life much harder for people that want to sell 6.0 as a painless migration. On the surface I like your idea of stat64 (regardless of politics of having 64-bit specific in the API names), but I'd like to think on it a bit. In the mean time I'm off to listen to Steve profess his love to Intel ;-) ScottReceived on Mon Jun 06 2005 - 14:12:30 UTC
