Summary of Change
Changes to libc To support IPv6 in HP-UX 11i v2, the following new Application
Programming Interfaces (APIs) have been introduced as part of HP-UX libc:
• setutsent()
• getutsent()
• getutsid()
• getutspid()
• getutsline()
• pututsline()
• endutsent()
• bwtmpname()
• endbwtmp()
• setbwtmp()
• updatebwdb()
• getbwent()
While providing support for IPv6, the new solution addresses the performance
scalability and feature scalability problems existing in the previous implementation.
This solution introduces a daemon, utmpd, and a library, libuseracct, to manage user
accounting on HP-UX.
To accommodate increases in the sizes of various fields of the structure at a future date
and for scalability, the new solution implements the user-accounting database as an
in-memory database of the daemon utmpd. HP-UX applications using the old /etc/utmp
and /etc/utmpx files to log user-accounting information (namely, telnetd, rlogind,
