OSS environment
OSS environment. The OSS API, tools, and utilities.
pathname. In the HP NonStop™ Open System Services (OSS) file system and Network
File System (NFS), the string of characters that uniquely identifies a file within its file
system. A pathname can be either relative or absolute. See also ISO/IEC IS
9945-1:1990 (ANSI/IEEE Std. 1003.1-1990 or POSIX.1), Clause 2.2.2.57.
PIC (position-independent code). Executable code that need not be modified to run at
different virtual addresses. External reference addresses appear only in a data area
that can be modified by the loader; they do not appear in PIC code. PIC is also called
shared code.
PIN. See process identification number (PIN).
private library. See user library (UL).
process. (1) A program that has been submitted to the operating system for execution, or a
program that is currently running in the computer. (2) An address space, a single
thread of control that executes within that address space, and the system resources
required by that thread of control.
process identification number (PIN). A number that uniquely identifies a process running
in a processor. The same number can exist in other processors in the same system.
program file. A loadfile containing a program’s main routine plus related routines statically
linked together and combined into the same object file. Other routines shared with
other programs might be located in separately loaded libraries. A program file can be
named on a RUN command; other code files cannot. See also object file.
pTAL. A machine-independent systems programming language based on TAL. The pTAL
language excludes architecture-specific TAL constructs and includes new constructs
that replace the architecture-specific constructs. Compare to HP Transaction
Application Language (TAL).
pTAL compiler. An optimizing native-mode compiler for the pTAL language.
public library. A dynamic-link library (DLL) or shared run-time library (SRL) that is known to
the operating system, available for execution by any process or user, and that is not an
implicit library.
reduced instruction-set computing (RISC). A processor architecture based on a
relatively small and simple instruction set, a large number of general-purpose registers,
and an optimized instruction pipeline that supports high-performance instruction
execution. Compare to complex instruction-set computing (CISC).
relative pathname. In the HP NonStop™ Open System Services (OSS) file system and
Network File System (NFS), a pathname that does not begin with a slash (/) character.
A relative pathname is resolved beginning with the current working directory. Compare
to absolute pathname.
