HP-UX 11i v3 March 2014 Release Notes

• HP-UX C Library (libc)
HP-UX C library (libc) - UNIX 2003 Standard Compliance: libc library enhanced to
comply with UNIX 2003 standards. A number of APIs have been added, while some
APIs have been modified.
◦
◦ HP-UX C library (libc) - Other Changes: New features include Tru64 API migration,
malloc(3C) thread local cache enhancements, long username and groupname.
◦ libc(1) Library: Deprecated. Is a HP-UX 10.20 compatibility “C” library available in HP-UX
11i. No immediate impact in HP-UX 11i v3. When the libc(1) library is obsoleted, all
programs linking to this library will not work. Hence you are encouraged to start migrating
your programs from libc(1) to libc(2) library.
◦ Networking libc APIs: The return value of the gai_strerror(3N) API has changed from
char to const char. Includes other changes as well.
• HP-UX Color-Curses: libcur_colr Library and Commands: Obsolete. Were declared
deprecated in HP-UX 10.30 and are not available in HP-UX 11i v3 PA-RISC.
• Java 2 Platform
Java JDK/JRE for HP-UX: HP-UX 11i v3 does not include Java 1.3 and Java 3D (J3D 1.4).
SDK/RTE version 5.0 has been updated to incorporate defect fixes.
◦
◦ Java Out-of-Box: Updated to incorporate defect fixes.
• New: libIO Library: libIO.so (for Itanium®-based systems) or libIO.sl (for PA-RISC
systems) is a shared library, which provides APIs for accessing the HP-UX I/O subsystem
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.
