linking
executable loadfile for a program or library. Compiling creates one linkfile per
independent source module. Contrast with loadfile.
linking. The operation of collecting, connecting, and relocating code and data blocks from
one or more separately compiled object files to produce a target object file.
local area network (LAN). A network that is located in a small geographical area and
whose communications technology provides a high-bandwidth, low-cost medium to
which low-cost nodes can be connected. One or more LANs can be connected to the
system such that the LAN users can access the system as if their workstations were
connected directly to it. Contrast with wide area network (WAN).
loadable library. A loadfile that offers functions and data to other loadfiles. In this manual,
dynamic-link libraries and hybrid shared run-time libraries are libraries. A library cannot
normally be invoked externally; for example, by a RUN command. Instead, it is invoked
by calls or data references from client loadfiles.
loader. A programming utility that transfers a program into memory so it can run. The
mechanism that brings loadfiles into memory for execution, maps them into virtual
address space, and resolves symbol references among them. Synonyms include
run-time loader and run-time linker. The loader for TNS and for TNS/R native programs
and libraries that are not position-independent code (PIC) is part of the operating
system. For PIC loadfiles, a loader called RLD works with the operating system to load
programs and libraries.
loadfile. An executable object code file that is ready for loading into memory and executing
on the computer. Loadfiles are further classified as executable programs (containing a
main routine at which to begin execution of that program) or executable libraries
(supplying routines or variables to multiple programs or separately loaded libraries). A
TNS code file might be both a loadfile and a linkfile; native code files are never both.
Contrast with linkfile.
loadList. A list of all the libraries that must be loaded for a given loadfile to execute. A
loadfile’s loadList includes all the libraries in the given loadfile’s libList plus all the
libraries in those loadfiles’ libLists, and so forth. It does not include the implicit libraries.
The loadList order is the sequence in which these loadfiles are to be loaded when they
are not already loaded by a previous operation. The loadList of the program includes
all the loadfiles present in the process, in the order they were loaded.
MAC address. See media access control (MAC) address.
management information base (MIB). A definition of management items for some network
components that can be accessed by a network manager. A MIB includes the names
of objects it contains and the type of information retained.
management process. A process through which an application issues commands to a
subsystem. A management process can be part of a subsystem, or it can be
associated with more than one subsystem. In the latter case, the management process
