library client
it can be a system-managed collection of preloaded routines. Source-code libraries fall
outside the scope of this glossary. See also dynamic-link library (DLL) and shared run-
time library (SRL).
library client. A program or another library that uses routines or variables from that library.
library file. See library.
library import characterization (LIC). A list of the export digests and relocation offsets of
all the libraries used to resolve symbols in a loadfile. It allows the loader and operating
system to determine when a file is being loaded in an environment equivalent to that
found by the linker or to a previous load (see fastLoad). A LIC is generated and stored
in the loadfile by the linker when a file is preset; it can be used in a subsequent load
step to determine whether the loadfile’s existing bindings can be reused. The operating
system can also retain the bindings as modified when a loadfile is loaded (see cached
bindings) and associate a LIC with those cached bindings, so that they can be reused
when the same file is again loaded in an equivalent environment.
LIC. See library import characterization (LIC).
LIF. See logical interface (LIF).
light-emitting diode (LED). A semiconductor device that emits light from its surface.
Indicator lights are composed of LEDs. See also indicator lights.
line. The specific hardware path over which data is transmitted or received. A line can also
have a process name associated with it that identifies an input/output process (IOP) or
logical device associated with that specific hardware path.
linear load. Electrical loads for which the impedance is constant regardless of the voltage,
so that if the voltage is sinusoidal, the current drawn is also sinusoidal.
line-handler process. See Expand line-handler process or Expand-over-ServerNet
line-handler process.
line interface unit (LIU). A dual-ported unit consisting of two parts: a communications line
interface processor (CLIP) and a line interface module (LIM). An LIU can communicate
with either the primary or the backup processor, providing fault tolerance. When it is a
component of the communications subsystem, an LIU communicates with either
processor through either of a pair of communications interface units (CIUs).
link. In the Open System Services (OSS) file system, a directory entry for a file.
link count. In the Open System Services (OSS) file system, the number of directory entries
that refer to a particular file.
linker. (1) The process or server that invokes the message system to deliver a message to
some other process or server. (2) A programming utility, which combines one or more
