  • File ord.c — part of check-in [6a14de1811] at 2019-07-20 23:37:03 on branch trunk — udpate xpriv to use sysv shmem by default; give iaia an option to generate its own types, and allow selecting between 7-bit and 8-bit encodings for ascii (defaulting to 8-bit); update mkpw to work with new iaia; update ord to add flag controlling byte length (7 or 8) for iaia's ascii mode (user: lexi, size: 10625) [annotate] [blame] [check-ins using]
