Please reread the information regarding bi-endian hardware and note that some can be configured to switch endianness on a per-page basis. That's with a single processor. Note also that the mapping of memory in different processes may be to different addresses (i.e. different pages). Given that there are two separate processes involved, I cannot safely assume that different endianness might never arise; it's certainly conceivable that the ntp side might be built big-endian (to simplify networking operations), while the other process might be little-endian (perhaps to more efficiently cope with hardware). _______________________________________________ questions mailing list questions@lists.ntp.org http://lists.ntp.org/listinfo/questions
