Glossary
absolute pathname. An Open System Services (OSS) pathname that begins with a
slash (/) character and is resolved beginning with the root directory. Contrast with
relative pathname .
accelerate. To speed up emulated execution of a TNS object file by applying the
Accelerator for TNS/R system execution or the Object Code Accelerator (OCA) for
TNS/E system execution before running the object file.
accelerated mode. See TNS accelerated mode .
accelerated object code. The MIPS RISC instructions (in the MIPS region) that result from
processing a TNS object file with the Accelerator or the Intel® Itanium® instructions (in
the Itanium instruction region) that result from processing a TNS object file with the
Object Code Accelerator (OCA).
accelerated object file. A TNS object file that, in addition to its TNS instructions (in the
TNS region) and symbol information (in the symbol region), has been augmented by
the Accelerator with equivalent but faster MIPS RISC instructions (in the MIPS region),
the Object Code Accelerator (OCA) with equivalent but faster Intel® Itanium®
instructions (in the Itanium instruction region), or both.
Accelerator. A program optimization tool that processes a TNS object file and produces an
accelerated object file that also contains equivalent MIPS RISC instructions (called the
MIPS region). TNS object code that is accelerated runs faster on TNS/R processors
than TNS object code that is not accelerated. See also
TNS Object Code Accelerator
(OCA) .
Accelerator region of an object file. The region (called the MIPS region) of an object file
that contains MIPS RISC instructions and tables necessary to execute the object file
on a TNS/R system in accelerated mode. The Accelerator creates this region. Contrast
with
OCA region of an object file . See also accelerated object file .
address space. The memory locations to which a process has access.
alternate path. A path not enabled as the preferred path. An alternate path can become a
private dynamic-link library (private DLL) when a primary path is disabled.
ANSI. The American National Standards Institute.
APE. See application program interface (API) .
API. See application program interface (API) .
application program interface (API). A set of services (such as programming language
functions or procedures) that are called by an application program to communicate with
other software components. For example, an application program in the form of a client
might use an API to communicate with a server program.
