I meant the above comparison of pointers might not work
(I'm not sure, as I have no big-endian to test). Look:

# iostat -t da,scsi,pass
tempstr=3D0x7fffffffcfa0, &tstr[5]=3D0x7fffffffcfc8
tempstr=3D0x7fffffffcfa8, &tstr[5]=3D0x7fffffffcfc8
tempstr=3D0x7fffffffcfb0, &tstr[5]=3D0x7fffffffcfc8


D'oh.. endianness doesn't matter with arrays *blush
(Unless that's some system with decreasing memory
addressing. Ok, nevermind.)
