domain error
domain error. A mathematical error that occurs when an argument value falls outside the
defined bounds, or domain, of the specified mathematical operation.
dynamic-link library (DLL). A PIC (position-independent code) library file that offers
functions and data for use by other loadfiles. In UNIX, a DLL is known as a shared
object file or a dynamic shared object (DSO). DLLs are supported in both Guardian
and Open System Services environments.
eld utility. A utility that collects, links, and modifies code and data blocks from one or more
position-independent code (PIC) object files to produce a target TNS/E native object
file. See also Binder and nld utility.
EMS. See Event Management Service (EMS).
enoft utility. A utility that reads and displays information from TNS/E native object files.
See also noft utility.
EpTAL compiler. An optimizing TNS/E native-mode compiler for the pTAL language.
Event Management Service (EMS). A Distributed Systems Management (DSM) product
that provides event collection, event logging, and event distribution facilities. EMS
provides different event descriptions for interactive and programmatic interfaces, lets
an operator or an application select specific event-message data, and allows for
flexible distribution of event messages within a system or network.
expression. Any series of symbols whose evaluation produces a value.
extended data segment. A segment that provides up to 127.5 megabytes of indirect data
storage. A process can have more that one extended data segment.
file scope. Scope that continues until the end of the translation unit.
function. A named body of executable code together with any private, or local, objects used
by that code.
function prototype scope. Scope that continues until the end of the enclosing function
declaration.
Guardian. An environment available for interactive or programmatic use with the HP
NonStop operating system. Processes that run in the Guardian environment use the
Guardian system procedure calls as their application program interface; interactive
users of the Guardian environment use the TACL or another HP product’s command
interpreter. Contrast with Open System Services (OSS).
Guardian environment. The Guardian API, tools, and utilities.
high PIN. A process number (PIN) in the range 256 or higher.
HP NonStop operating system. The operating system for HP NonStop servers.
