6.12 Security
The Security manual contains information about migrating a programming
interface from ULTRIX to DIGITAL UNIX, including basic migration issues
and ways to move ULTRIX authentication files to a DIGITAL UNIX system.
The DIGITAL UNIX system does not support the functions for getting and
setting authorization entries in the auth database. See the discussion of
secauthmigrate in the Security manual for more information.
Additionally, Section B.18 contains a list of security-related header files
that exist in ULTRIX but do not exist on a DIGITAL UNIX system.
6.13 Curses Libraries
The curses package is a set of cursor optimization routines for writing
screen-management programs. ULTRIX and DIGITAL UNIX systems both
support X/Open and BSD curses library routines. The capabilities in both
of these libraries have been extended beyond what is available with Version
4.2 and Version 4.3 of the ULTRIX system. For example, the DIGITAL
UNIX curses package provides multibyte character support.
ULTRIX applications will need to change references to header files and
libraries. See Section 7.2, Section 7.7, and Section 4.7 for more information.
