HP-UX 11i v3 March 2012 Release Notes

information. The library will reduce the dependency on other HP-UX commands for I/O
information.
• libpthread Library: Added new API, pthread_setschedprio(), to set scheduling priority
of target thread.
• Link Editor (ld): Additional linker options introduced since patch PHSS_34440, June 2006,
and other changes.
• Mercury Library (libhg): Provides high performance interfaces between the user programs
and the kernel making it possible to transfer key pieces of information back and forth at high
speeds.
• Software Transition Kit (STK): Designed to help transition HP-UX applications from earlier
versions of HP-UX to the latest version of HP-UX. Will not be available for HP-UX 11i v3.
• Threads Renice facility: Two new pthread APIs to change nice value of a thread in a
multi-threaded process.
• UNIX 2003 Standard Profile Conformance: New functions and compiler conformance as
defined in Single UNIX Specification version 3. The Precision Architecture (PA) systems have
most of the UNIX 2003 features available for applications. Since the C99 compiler will not
be available on PA, full UNIX 2003 branding is not supported. Itanium®-based systems fully
conform and are branded to UNIX 2003.
• Unwind Library (libunwind): Updated to version 1.48. Performance of the unwind express
APIs has been improved substantially; U_STACK_TRACE(3X) and _UNW_STACK_TRACE(3X)
APIs have been enhanced; new APIs have been added to the unwind express portion of the
library.

• New: Locale Versioning: localedef/libc UNIX 2003-related I18N changes. New locale version
“locales.3” has been generated for all system supported locale binaries. This has been provided
to protect older PA-RISC-based archived applications from unexpected systems behavior in
order to fully support the UNIX 2003 standard.
• UNIX 2003 Support: The localedef, locale and iconv commands and the associated
C library APIs, locale databases and iconv converters have been updated to align with the
UNIX 2003 standard.

• New: Messaging Commands: mkcatdefs, dspmsg, and dspcat . Added to HP-UX for
compatibility with Tru64 UNIX.

system.config.iconv file provided to separate the HP-UX core OS iconv mapping table
information from the layered third-party and user-specific iconv mapping table information.
• Japanese Mainframe Character Set: iconv now supports an extended area of Japanese
mainframe character sets.
