aCC(1) options used to compile. Newly delivered as a recommended product on the BOE,
HA-OE, VSE-OE, and DC-OE.
• New: Copy-On-Write Functionality for Private Memory Objects: Provides copy-on-write
functionality for privately mapped files, private segments of child process after fork(2) and
private segments locked by mlock(2).
• New: getenv Performance Enhancement: Enhances the performance of the libc API
getenv(3C) for threaded applications. Delivered as an optional product in all OEs.
• New: HP MLIB: In TCOE, V9.5 includes a defect fix. HP MLIB is newly delivered as an optional
product in VSE-OE, HA-OE, and DC-OE.
• New: HP-MPI: Newly delivered as an optional product in BOE, VSE-OE, HA-OE, and DC-OE.
• New: HP Wildebeest Debugger: An HP-supported implementation of the Open Source GNU
debugger (GDB). Enables you to debug C, C++, and FORTRAN applications (32 bit and 64
bit versions) on Integrity and PA-RISC systems. Newly added as a recommended product to
the BOE, HA-OE, VSE-OE, DC-OE.
• New: HP-UX Atomic APIs (libatomic): Usage of these APIs avoid the use of mutex locks or
semaphores in certain scenarios. Delivered as an optional product in all OEs.
• New: Improved Support for Multi-threaded Applications: Extends the mpctl(2) API and adds

can be accessed and modified by kernel contexts, avoiding the copying in and out of data
when system calls are invoked.
• New: libc Enhancement: Contains a new API called memsetU16(3C), which can be used
for memory operations to set area in memory to contain 2-byte word. Delivered as an optional
product in all OEs.
• New: patch_active_text: Allows mprotect() write access to the text of a running process
such that the active text can be modified.
