Open System Services Porting Guide (G06.29+, H06.06+, J06.03+)

Guardian services An application program interface (API) to the HP NonStop™ operating system, plus the tools and
utilities associated with that API. This term is synonymous with Guardian environment.
See also Guardian.
hard link The relationship between two directory entries for the same file. A hard link acts as an additional
pointer to a file. A hard link cannot be used to point to a file in another fileset. Contrast with
symbolic link.
header Generically, a collection of information, typically at or before the beginning of a structure,
aggregate, message or other object, containing information about that object.

2. A header file.
header file A source file included by reference in other source files, typically to define an interface or set of
facilities.

IEC International Electrotechnical Committee. IEC is a professional organization that creates or adopts
standards for computer hardware, environments, and physical interconnections.
IEEE Institute of Electrical and Electronics Engineers. IEEE is a professional organization whose
committees develop and propose computer standards that define the physical and data link
protocols of entities such as communication networks.
ILP32 The C/C++ data model where int, long, and pointer data types are all 32 bits wide; also
used as the C/C++ 32-bit compiler pragma.
See also LP64.
Intel® Itanium®
instructions
Register-oriented Itanium instructions that are native to and directly executed by a TNS/E system.
Itanium instructions do not execute on TNS and TNS/R systems. Contrast with TNS instructions
and RISC instructions.
internationalization.
The process of designing and coding software so that it can be adapted to meet the needs of
different languages, cultures, and character sets, with the ability to handle various linguistic and
cultural conventions. Internationalization methods enable the processing of character-based data
independently of the underlying character encoding, allowing choice among character sets.
Sometimes referred to as I18N, derived from the 18 letters between the initial I and the final N
of the word internationalization. See also character set.
interoperability The ability of programs and functions in one environment to operate on data, files, and other
objects from another environment. For example, OSS processes can perform many operations
on Guardian files, and Guardian processes can perform some operations on OSS files.
ISO International Organization for Standardization. ISO is an international body that drafts, discusses,
proposes, and specifies standards for network protocols. ISO is best known for its seven-layer
reference model that describes the conceptual organization of protocols.
ISO is sometimes called the “International Standards Organization”; although ISO is the official
abbreviation, it does not correspond to the organization’s name in any language.
