Looking in the most recent ntpshm.c I see only the calls to shmget and shmat. But I think you are right, it should be quite simple to add a compilation conditional and replace it with mapping calls similar to what is found in the Windows port of ntpd. However, it could also be that libraries that come with cygwin already do that translation. _______________________________________________ questions mailing list [email protected] http://lists.ntp.org/listinfo/questions
